Abstract:

In spite of the remarkable achievements in the healthcare sector over recent decades, inequities in accessibility and affordability of these facilities coexist throughout Pakistan. Thus, we aimed to explore and document the cultural knowledge of herbal teas used medicinally by the local community members of Manoor Valley, Pakistan. Field investigations were undertaken during the summer season of 2015–2017, and cultural practices of medicinal plant usage for treating various ailments were gathered through interviews of the local inhabitants. Ethnomedicinal insights of the medicinal plants used in herbal teas were gained with different indexes. Our results revealed 27 plant species, comprising of herbs (70%), shrubs (26%), and trees (4%), which were used for treating 21 diseases. Plants belonged to 18 families: Asteraceae and Lamiaceae were the leading families used for treating diseases. Diarrhea and gas troubles were the most frequent diseases. Based on indexes values, Cannabis sativa was the dominant species used. The results revealed that 57% of medicinal uses are new to literature. This ethnomedicinal study is providing the first insights into the traditional medication system of Lesser Himalaya, Pakistan, through ethnomedicinal teas.

Abstract:

Objectives. The present analysis was to investigate the content of caffeic acid derivatives, antioxidant activity, and the presence of caffeic acid in alcoholic extracts obtained from 16 simple teas from the following medicinal plants: Vaccinium mуrtilluѕ, Camеllia ѕinеnѕiѕ, Coffea arabica, Mеlіssa οffіcіnalіs, Οcіmum basіlіcum, Rοsmarіnus οffіcіnalіs, Salvіa οffіcіnalіs, Ηyssοрus οffіcіnalіs, Αrtеmіsіa absіntһіum, Cynara scοlymus, Calendula officinalis, Cοrіandrum satіvum, Fοеnіculum vulgarе, Carum carvі, Rοsa canіna, Crataеgus mοnοgyna. Materials and methods. The presence of caffeic acid was evaluated using the thin layer chromatography method (TLC). The total content of phenylpropanoids from the medicinal herbs alcoholic extracts was determined using a spectrophotometric method. Outcomes. Results were in the range of 0.046-2.426% caffeic acid derivatives (CAE%). The antioxidant properties were measured using the DPPH radical scavenging mechanism. The results were found to be in the range of 63.93% and 0.38% inhibition level (I%). The greatest antioxidant activity was measured for Camellia sinensis (I = 45.54%), followed by Vaccinium myrtillus (I = 50.289%). Conclusions. In this paper it was shown that these medicinal plants are rich in caffeic acid derivatives with antioxidant action capitalized in the prevention of serious diseases.

Abstract:

Teas made from 18 Hungarian medicinal plants were investigated for their total phenolic content and antioxidant effect as radical scavenging activity using the Folin-Ciocaltau and DPPH assays. Antimicrobial effect of the herbal teas was measured by agar diffusion method. In total, the results showed that the smallflower hairy willowherb (Epilobium parviflorum) had the highest antioxidant effect among the plants studied. Teas made from fennel (Foeniculum vulgare) and bean pods (Phaseoli legumen) have the lowest activity. Only four herbal teas showed some antimicrobial activity: the smallflower hairy willowherb (Epilobium parviflorum), common agrimony (Agrimonia eupatoria), spearmint (Mentha crispa) and bean pods. At smaller concentrations the relationship found between total phenolic content and radical scavenging activity was linear but with increasing phenol content the antioxidant activity remained the same.

Abstract:

Various herbal teas including German chamomile, Chrysanthemum Vascuflow herb tea, hop, jasmine and orange flowers, sweet marjoram, spearmint and thyme leaves, and papaya-mint tea as well as coffee substitutes (Bambu instant Swiss, Teeccino chocolate-mint, and Teeccino Mediterranean Espresso) were analyzed for fungal contamination and the presence of aerobic mesophilic bacteria (APC). The results of this investigation showed that fungal counts reached levels as high as 5.8 × 105 colony forming units (cfu) per gram. German chamomile harbored the highest fungal contamination. The most common fungi found in herbal teas were Aspergillus niger, Penicillium spp., Eurotium rubrum, E. chevalieri, A. flavus, Fusarium spp., Alternaria alternata, and yeasts. Among the coffee substitutes, only the chocolate-mint coffee was contaminated with low numbers (<1.0 × 103 cfu g-1) of E. rubrum, Ulocladium spp. and Phoma spp., and with yeasts (< 100–6.8 × 103 cfu g-1). Aerobic mesophilic bacteria were recovered from 100% of the herbal tea, chocolate-mint and Mediterranean Espresso, and from 50% of the Bambu instant Swiss coffee samples. The highest APC counts of 1.2 × 107 cfu g-1 were observed in spearmint leaves.

Abstract:

The plants that make up herbal tea have a complex chemical composition and can be related to drug collections and have various pharmacological properties that affect human health. In addition to organic acids, vitamins, flavonoids, essential oils, the medicinal properties of plants are affected by macro- and microelements included in their composition. Macronutrients and microelements determine the medicinal properties of plants, are substances necessary for human growth and normal development. The composition of seven herbal teas developed in the scientific center of the North Ossetian State University after K.L. Khetagurov, each of which contains from 3 to 8 plant components was analyzed. Plant material was collected in the summer of 2018 in the mountainous and foothill areas of North Ossetia (Central Caucasus). Using instrumental neutron activation analysis and atomic absorption spectrometry, the presence and determination of 37 elements was carried out for the first time in herbal teas (Na, Mg, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Mo, In, Sb, Cs, Ba, La, Ce, Sm, Tb, Hf, Ta, W, Au, Th, and U). The results are discussed in terms of using the studied herbal teas as a safe source of trace elements. Herbal teas can be used as functional foods that are not a drug, but replenish the human body with important compounds and elements that have a definite positive effect on the body.

Abstract:

PURPOSE: Thirty-five commercially available Camellia sinensis (black and green) and herbal leisure teas and an assortment of Traditional Chinese medicinal teas were randomly selected and examined for their potential to inhibit the drug metabolizing enzyme cytochrome P450 3A4 (CYP3A4). The study was then extended to examine CYP2D6*1 and CYP2D6*10. METHODS: Microtiter fluorometric assays were utilized to examine the potential for the teas to inhibit CYP-mediated metabolism. Aqueous or alcoholic extracts of the dried tea plant material were examined. METHODS: Most of the black and green leisure teas generally inhibited CYP3A4 more than the Chinese medicinal teas. The medicinal Chinese teas were generally more inhibitory towards CYP3A4 compared to the CYP2D6 isozymes, and the aqueous extracts displayed more potency than the alcoholic extracts. CONCLUSIONS: Tea whether used for leisure or medicinal purposes has the potential to inhibit CYP3A4-mediated drug metabolism particularly black tea.This article is open to POST-PUBLICATION REVIEW.

Abstract:

Cronobacter sakazakii is an important cause of human infections that can be serious and even fatal among premature neonates and immunocompromised adults or infants. Because of its high tolerance to osmotic stress, C. sakazakii is frequently isolated from dried foods, such as powdered infant formula and herbal teas. The aim of investigation was detection, identification and molecular characterization of Cronobacter sakazakii isolates from infant formula and various herbal teas collected from Serbian market and tested for import control. C. sakazakii was not detected in any of the 360 analysed samples of powdered infant formula. However, 192 out of 520 samples of herbal teas tested were positive for C. sakazakii (37.1%). The high prevalence was observed in teas for children (51.6%) and in ?baby? teas (44.1%), followed by medicinal teas (38%). The largest one-herb-teas group (221 samples) contained 72 C. sakazakii-positive samples (32.6%) and involved Sennae folium, Althaeae radix, Menthae piperitae folium, Chamomilae flos and Urticae folium teas. Molecular characterization of isolated C. sakazakii from different herbal teas by rep-PCR, RAPD and 16S rRNA sequences analysis showed the high similarity to C. sakazakii NCTC 8155. Knowing this strain as one of the most pathogenic clinical strains, our results raise concern about the safety risks these foods pose to immunocompromised and healthy consumers, especially for babies and children.

Abstract:

Although traditional green and black tea is the world’s favourite drink, health or herbal “teas” are becoming increasingly popular. Despite the diversity of indigenous South African plants, only two herbal teas, namely honeybush and rooibos, are presently being produced on a commercial basis. However, a “tea” obtained from the Athrixia phylicoides plant, is extremely popular in the eastern interior of the country and may have commercial potential. Two ethnobotanical surveys were conducted in the Limpopo Province and in KwaZulu-Natal to obtain information on the traditional use of the plant amongst different ethnic groups. It was found that A. phylicoides is used as a herbal “tea”, as a medicine and for the making of brooms. Although A. phylicoides tea is very popular, the plant is most often used for the making of brooms. Medicinally it is used to treat “heart problems”, high blood pressure and diabetes. Only minor ethnically-based differences in medicinal use were revealed by the surveys. Its symbolic value and use during religious ceremonies were previously undocumented. Owing to indiscriminate harvesting techniques practised by pickers from urban areas, the plant is becoming increasingly scarce and may be faced with local extinction.

Abstract:

We evaluated the antimicrobial activities of seven green tea catechins and four black tea theaflavins, generally referred to as flavonoids, as well as the aqueous extracts (infusions) of 36 commercial black, green, oolong, white, and herbal teas against Bacillus cereus (strain RM3190) incubated at 21°C for 3, 15, 30, and 60 min. The results obtained demonstrate that (i) (−)-gallocatechin-3-gallate, (−)-epigallocatechin-3-gallate, (−)-catechin-3-gallate, (−)-epicatechin-3-gallate, theaflavin-3, 3′-digallate, theaflavin-3′-gallate, and theaflavin-3-gallate showed antimicrobial activities at nanomolar levels; (ii) most compounds were more active than were medicinal antibiotics, such as tetracycline or vancomycin, at comparable concentrations; (iii) the bactericidal activities of the teas could be accounted for by the levels of catechins and theaflavins as determined by high-pressure liquid chromatography; (iv) freshly prepared tea infusions were more active than day-old teas; and (v) tea catechins without gallate side chains, gallic acid and the alkaloids caffeine and theobromine also present in teas, and herbal (chamomile and peppermint) teas that contain no flavonoids are all inactive. These studies extend our knowledge about the antimicrobial effects of food ingredients.

Abstract:

The State Pharmacopoeia of the Russian Federation 14th ed. suggests to standardize herbal teas using the procedures presented in the pharmacopoeia monographs but this approach is not always relevant due to complexity of this dosage form composition. The purpose of investigation is to estimate quality of herbal teas utilizing monographs recommended by the State Pharmacopoeia of the Russian Federation 14th ed. for the individual components of teas and suggest feasible alternative approaches to standardization of multicomponent herbal drugs. The objects of investigation Pectorales species № 1 and Proctofitol. Detection of substances was carried out using chromatographic (TLC and HPLC) and spectrophotometric methods recommended by the State Pharmacopoeia of the Russian Federation 14th ed. for individual components measured in term of marker biological active substances or substances found in the course of quality analysis. It has been found out that the content of flavonoids measured in terms of giperosid surpasses over the equivalent figure in terms of luteolin in the extractions from Pectorales species № 1. The content of hydroxycinnamic acids in the same tea measured in terms of rosmarinic acid surpasses over the equivalent figure in terms of chlorogenic acid. Analysis of anthracene derivates in the Proctofitol has shown that the adsorption maximum of phenolate solution of anthracene derivates (523 nm) coincides with maximum by which was calculated the mass attenuation coefficient of sennoside B (523 nm) (for chrysophanic acid = 515 nm) and the maximum of adsorption of extraction from the tea with using alcohol solution of magnesium acetate (515 nm) coincides with maximum by which was calculated the mass attenuation coefficient of glucofrangulin A. Preliminary cleaning Proctofitol off anthracene derivates allowed to estimate the content of glycyrrhizic acid more completely. The giperosid was suggested as a marker substance for determination of flavonoids, rosmarinic acid was suggested as a standard for hydroxycinnamic acids in Pectorales species № 1. The sennoside B was suggested as a marker for estimating of content of anthracene derivates in the Proctofitol and the necessity of cleaning this tea off anthracene derivates when defining glycyrrhizic acid was proven.

Abstract:

Purpose The purpose of this paper is to investigate the health and medicinal importance of bush tea (Athrixia phylicoides DC) and special tea (Monsonia burkeana Planch. ex Harv), two of Southern African indigenous herbal teas. Design/methodology/approach The two herbal teas, A. phylicoides and M. burkeana were extracted individually and in combined ratios for analysis. The phenolic content was determined and the different phenolic compounds were identified using thin-layer chromatography (TLC) and high-performance liquid chromatography (HPLC). The anti-diabetic activity of the teas was determined by evaluating the inhibition of both α-amylase and α-glucosidase in vitro. The anti-proliferative activity was measured on human cervical cancer (HeLa) cell line using the MTT (3-(4,5-dimethylthiazol-2-yl)2,5-diphenyltetrazolium) assay. Findings Gallic acid, chlorogenic acid and quercetin were identified to be present in significant quantities by TLC. The HPLC quantified the presence of catechin (1.567 mg/g) and chlorogenic acid (1.862 mg/g) in special tea while chlorogenic acid (1.288 mg/g) was present in bush tea. Bush tea and special tea expressed significant levels of phenolic content and high antioxidant activities. Special tea (S100) expressed high inhibition of α-amylase, α-glucosidase and HeLa cell line proliferation when compared to bush tea (B100). Originality/value Both bush tea and special tea could provide an alternative for treatment and management of both diabetes and cervical cancer. However, future studies are needed to investigate their synergistic effect with a wide range of other commercial herbal teas.

Abstract:

Traditional Indian medicine (ayurveda) is becoming increasingly popular, with many chronic conditions responding to it well. Most patients begin to take conventional medications as soon as their diagnoses are made, so ayurvedic treatments are usually undergone alongside and/or after conventional medical approaches. A detailed knowledge of the action of food, spices, and medicinal plants is needed in order to understand their potential influence fully. While societal use of ayurvedic plants and Indian spices is commonplace, without ill effect, the use of more concentrated products made from single plants, often in the form of teas or tablets, is of more concern. The mechanisms by which polyherbal drugs and their extracts act differ in many respects from the actions of single substances or synthetic drugs. Despite the fact that ayurvedic medicines are based on natural herbal materials, their safety depends on their method of administration, taking into account individuals’ needs and their specific disease conditions.

Abstract:

The purpose of this study was to measure the potential levels of fumonisin B1 (FB1) and fumonisin B2 (FB2) contamination in several herbal teas and medicinal plants that are consumed regularly in Turkey. FB1 and FB2 were detected using high-performance liquid chromatography with fluorescence detection after derivatization with o-phthaldialdehyde. A total of 115 commercially available herbal tea and medicinal plant samples were analyzed. The recoveries in black tea were 86.9 ± 8.42% for FB1 and 102 ± 6.80% for FB2 spiked with 1 μg/g of each analyte. Similarly, the mean recovery results in lime (linden) for FB1 and FB2 were 85.2 ± 9.76% and 78.6 ± 5.67%, respectively. The minimum detectable amounts for the o-phthaldialdehyde derivatives of FB1 and FB2 were 0.025 μg/g (1 ng injected) and 0.125 μg/g (5 ng), respectively. FB1 was detected in two samples (0.160 and 1.487 μg/g), and FB2 was detected in none of the samples.

Abstract:

The identification of yacon, a medicinal plant, in tea mixtures by rapid Polymerase Chain Reaction (PCR) and the Direct Analysis in Real Time coupled with Time-of-Flight Mass Spectrometry (DART/TOF-MS) method were evaluated. Three tea products and a pure yacon tea were analysed using the molecular method PCR, concretely the intraspecific variation of the internal transcribed spacer (ITS) regions of rDNA and the DART method coupled with TOF-MS. The results show the reliability of PCR and restriction cleavage of the ITS as a combined approach to confirm the presence of yacon in herbal tea mixtures. Three fragments of approximately 700, 408, and 235 bp in length are present when yacon is a part of the herbal tea mixture. The Principal Component Analysis (PCA) based on the fingerprints of the complete Total Ion Current (TIC) mass spectra shows sufficient separation of herbal teas with and without yacon leaves. The reported methods are technically rapid and can be used as an effective tool for the purposes of yacon identification or authentication.

Abstract: The consumption of herbal teas is becoming more and more popular nowadays both as luxury foods and a complementary part of medical therapy. Beside the organic agents of medicinal plants, the presence of inorganic ions is also relevant in exerting the favorable pharmacological effect. The author briefly summarizes the importance of some essential metal ions and their quantitative values in teas applied in the adjuvant therapy of diabetes and used as diuretics. The common feature of teas used in diabetes is that they contain a measurable amount of chromium and the concentration of most essential elements (such as K, Mg, Mn and Zn) is significant, which can be considered as a mineral source for some metal ions. Diuretic herbs have an outstanding K content, but from the point of view of diuresis, the large K/Na molar ratio above 50 is relevant. Orv Hetil. 2018; 159(18): 713–719

Abstract:

This work analyzed the labels of medicinal teas from formal trade, according to the specific legislation. Thirty samples of herbal drugs included in the Form of Phytotherapeutics of the Brazilian Pharmacopeia were photographed in commercial establishments in Rio de Janeiro state, Brazil, and analyzed according to the Resolution of Anvisa RDC 26/2014 and the Form. Information related to the botanical nomenclature, plant part, guidelines for preparation, warnings, claims, and orientations for use was inconsistent with the official standards in most samples, and 77% were marketed as food products, although the studied species are not regulated for the commercialization in the food area. The consumption of herbal products in disagreement with the official recommendations may cause toxic effects or lack of the expected benefits. The irregularities identified suggest the absence or failure in quality control and a lack of concern for the scientific botanical nomenclature, exposing the public health to risks.

Abstract:

The province of Cordoba in central Argentina is naturally rich in aromatic and medicinal herbs that are in high demand as ingredients in teas and herbal medicines. Most of the herbs sold are harvested from natural populations, and this activity is a primary source of income for families in the Sierra de Cordoba region. As a result of over-collection and other poor harvesting practices, many native plant populations have been reduced in size or extirpated. The economic consequence of the gradual decline of this resource has been a loss of real income in rural areas coupled with a pattern of emigration from small towns to larger cities. PRODEMA is a collaborative effort by universities in Argentina and the United States, with the sponsorship of the Cordoba government, to domesticate and to market the most commercially important species. Horticultural research has focused on the development of propagation techniques and identification and selection of desirable chemotypes.

Abstract:

Recent scientific studies have proven the importance of trace elements on human health. The main food supplies are plants and animals, which are significant sources of these minerals. Studies on determining mineral compositions of herbs, spices and some other crops have increased all over the world. Published works revealed that spices, herbs and medicinal plants should be consumed to obtain beneficial trace elements. Selenium (Se), one of the most vital trace elements, has a significant role in human diet acting as a preventative agent against some serious illnesses. Despite numerous scientific works on mineral compositions of medicinal and aromatic plants, investigations of selenium content in these foods could not be successfully studied until recently due to the lack of suitable analytical methods for selenium analysis. Thus, publications on selenium concentrations of foods are recent. In this regard, selenium contents of some medicinal and aromatic plants commonly used as spices, herbal teas and traditional medicines in Turkey were studied in the present research. Selenium contents of the most used parts of these plants were analyzed by ICP-OES (Varian Vista-Pro, Australia). Of the analyzed 26 medicinal and aromatic plants, the highest Se concentration (1133 μg kg-1) was found in sweet basil ( Ocimum basilicum L.) and the lowest in sumac ( Rhus coriaria L.) fruits (11 μg kg-1).

Abstract:

Summary In the study, the relationships were investigated among N, P, Fe, Zn, Mn and Cu, in medicinal plant raw materials (herbal bags) and their water-soluble chemical forms in infuses. 42 independent samples of plant materials were chosen, represented by different morphological plant parts as herbs, leaves, flowers and fruits. The elements were determined by UV/Vis spectrometry (non-metals), and FAAS (metallic elements) after previous mineralization of plant samples (total concentrations), and directly in herbal teas (water-extractable forms). Most frequently the correlations between non-metals and Zn and Mn occurred, both between their total contents the water-extractable forms. Statistically significant correlations were also found in pairs: Zn-Mn, Fe-Zn, Mn-Fe, and Cu-Zn. Application of multivariate analysis revealed that cluster analysis grouped the studied samples into clusters with similar levels of the analyzed elements, and principal component analysis allowed the identification of water-extractable Zn, P-PO4 and water-extractable Cu as the most crucial factors determining the differentiation of the studied plant samples.

Abstract:

This survey focuses on the problem of medicinal plants contamination due to environmental pollution produced by many different industrial activities and atmospheric deposition of some toxic compounds. This analysis is important since plants can easily absorb organic and inorganic compounds from all environmental compartments (water, soil, air), which can enter and be transferred in the trophic chain, up to humans. Medicinal plants are relevant for study in relation with their interactions with different contaminants, in particular those inorganic persistent as heavy metals, because they are used in entire world for their beneficial properties, and represent a significant part of traditional medicine. According to World Health Organization (WHO), 65-80% of world`s population depends on herbal products as the primary form of health care. Frequent use of medicinal plants to improve health, in the context of current pollution, requires special attention, since they can contain heavy metals in their structures, which can generate hazards and risks on human health throughout the subsequent consumption of contaminated medicinal plants as teas, other drinks, cosmetics.

Abstract:

In the present study, eight plant species belonging to Lamiaceae family were identified as ingredients for herbal teas in the region of Sharri Mountains: Thymus serpyllum, Rosmarinus officinalis, Melissa officinalis, Origanum vulgare, Mentha longifolia, Ocimum basilicum, Teucrium chamaedrys, and Sideritis scardica, respectively. Chemical composition of essential oils obtained from these species was analyzed using GC-MS and GC-FID with the aim of examining their volatile compound profiles, responsible for their respective flavors and fragrance. Principal Component Analysis (PCA) was performed with the aim of grouping plant species under study on the basis of their chemical composition. Experimental data revealed the typical volatile constituent pattern for the Lamiaceae family. Monoterpenes and sesquiterpenes, responsible for flavor and medicinal use of these plants, were the most abundant groups of the volatile constituents. PCA data analysis resulted in the grouping of these analyzed species in four principal clusters.

Abstract:

Rhinacanthus nasutus (L.) Kurz (Acanthaceae) (Rn) is an herbaceous shrub native to Thailand and much of South and Southeast Asia. It has several synonyms and local or common names. The root of Rn is used in Thai traditional medicine to treat snake bites, and the roots and/or leaves can be made into a balm and applied to the skin for the treatment of skin infections such as ringworm, or they may be brewed to form an infusion for the treatment of inflammatory disorders. Rn leaves are available to the public for purchase in the form of “tea bags” as a natural herbal remedy for a long list of disorders, including diabetes, skin diseases (antifungal, ringworm, eczema, scurf, herpes), gastritis, raised blood pressure, improved blood circulation, early-stage tuberculosis antitumor activity, and as an antipyretic. There have been many studies investigating the roles of Rn or compounds isolated from the herb regarding diseases such as Alzheimer’s and other neurodegenerative diseases, cancer, diabetes and infection with bacteria, fungi or viruses. There have, however, been no clinical trials to confirm the efficacy of Rn in the treatment of any of these disorders, and the safety of these teas over long periods of consumption has never been tested. This review assesses the recent research into the role of Rn and its constituent compounds in a range of diseases.

Abstract:

The important effect of dietary factors on health status has been recognized since antiquity. Since the discovery of the beneficial effects of dietary phytochemicals and bioactives, a new dimension of foods have emerged in the market. These “functional foods” are being developed by all major food companies and new ones are regularly brought into the market. While developing new functional foods and nutraceuticals, the association and identification of such foods and beverages with traditional foods and medicinal preparations, and/or popular forms of existing products are bound to bring long-standing consumer acceptance, which is an important desirable factor in sales and marketing. Following this concept, Zafi Beverages, Inc., Chicago, is developing a new line of functional products (new herbal teas and energy drinks). Zafiis also introducing a unique marketing and distribution system to create a new team of entrepreneurs, providing an excellent opportunity for growth in sales and marketing to new entrepreneurs. It targets ethnic entrepreneurs by offering an opportunity to use their networking abilities and be part of an exciting new partnership in the new host country, as well as a strategic business plan. The ethnic entrepreneurs are also constantly in contact with their consumers by virtue of the existing ethnic allegiance and cohesion and are able to identify the consumer needs and concerns directly. These small ethnic entrepreneurial networks can be identified as distinct “micro-marketing systems” within the national economy. The advertised market potential for Zafi is summarized to include an offer of immediate cash flow, more revenue and profits, marketing and financial education support, as well as a promising new line of products.

Full text

Abstract:

Pyrrolizidine alkaloids (PAs) are distributed in plant families of Asteraceae, Boraginaceae, and Fabaceae and serve in the chemical defense mechanism against herbivores. However, they became a matter of concern due to their toxicity associated with the high risk of intake within herbal preparations, e.g., phytopharmaceutical formulations, medicinal teas, or other plant-derived drug products. In 1992, the German Federal Ministry of Health established the first limits of PA content for fourteen medicinal plants. Because of the toxic effects of PAs, the Federal Institute of Risk Assessment (BfR) established more stringent limits in 2011, whereby a daily intake <0.007 µg/kg body weight was recommended and valid until 2018. A threefold higher limit was then advised by BfR. To address consumer safety, there is the need for more efficient extraction procedures along with robust, selective, and sensitive analytical methods to address these concerns. With the increased prevalence of, e.g., phytopharmaceutical formulations, this timely review comprehensively focuses on the most relevant extraction and analysis strategies for each of those fourteen plant genera. While a variety of extraction procedures has been reported, differences in PA content of up to 1110 ppm (0.11% (w/w)) were obtained dependent on the nature of the solvent and the applied extraction technique. It is evident that the efficient extraction of PAs requires further improvements or at least standardization of the extraction conditions. Comparing the various analytical techniques applied regarding selectivity and sensitivity, LC-MS methods appear most suited. This review shows that both standardized extraction and sensitive determination of PAs is required for achieving appropriate safety levels concerning public health in future.

Abstract:

Primula veris L. and Primula elatior (L.) Hill represent medicinal plants used for the production of herbal teas and preparations with antioxidant and expectorant activity. Flowers and roots of both species possess the same biological activity. In the presented study, raw materials of wild growing P. veris and P. elatior were compared in terms of the content and composition of phenolic compounds using a fast and simple HPLC-DAD method. The study showed that flowers of both species were rich in flavonoids. However, P. veris flowers were characterized with a distinctly higher content of isorhamnetin-3-O-glucoside, astragalin, and (+)-catechin, whereas P. elatior occurred to be a richer source of rutoside and isorhamnetin-3-O-rutinoside. Hyperoside was found exclusively in P. elatior flowers. Phenolic glycosides (primverin and primulaverin) were identified only in the roots. Their content was about ten times higher in P. veris in comparison with P. elatior underground organs. The obtained results clearly show that both Primula species differ distinctly in terms of the content and composition of phenolic compounds. The compounds differentiating both species to the highest degree (hyperoside, in flowers, as well as primverin and primulaverin, in the roots) may be useful chemical markers in the identification and evaluation of both species.

Abstract:

Commonly, the production of herbal medicines is more advantageous economically than chemical synthesis. Agricultural crops, having sufficient raw material base, are of main interest. In this respect the shells of haricot bean (Phaseolus vulgaris L. (Fabaceae)), that are waste products of beans, are of special interest. Due to the absence of regulatory documents for this kind of drug raw material in Ukraine the development of standardization parameters for the raw material of haricot bean is a very topical. Pharmacotherapeutic action of this drug raw material is caused by the presence of amino acids, proteins, macro- and microelements as well as flavonoids. There are medicines at the pharmaceutical market of Ukraine that was produced from the haricot bean: «Sadifit» (ZAO «Liktravy», Ukraine), «Arphazetin» (ZAO Pharmaceutical plant «Viola», Ukraine), «Hepatophyt» (LLC «Research and production pharmaceutical company «AIM», Ukraine), «Shells of haricot bean» (ZAO «Liktravy», Ukraine). Medicines are introduced to the market in the form of medicinal herbs mixture that's why main method of application is a preparation of restorative drinks, tinctures, teas. In light of this, study of amino acid composition in the water extracts from raw material is reasonable. Research of qualitative and quantitative amino acid composition of 5 lots of the shells of haricot bean was carried out by HPLC method. This raw material was harvested in different regions of Ukraine over a period of 2014 – 2016. 16 amino acids were identified in the water extracts of the shells of haricot bean. Glutamic acid (1.60 – 5.56 ´µg/100 mg), L-alanine (1.41 – 2.23 µg/100 mg), L-arginine (0.65 – 2.12 µg/100 mg) had the greatest content in the investigated samples. D-serine (0.04 – 0.13µg/100 mg) and D,L-methionine (0.02 – 0.43 µg/100 mg) had the lowest quantity in the investigated samples. Sufficiently high content of amino acids makes it possible to consider them as potential substances-markers at the development of assay procedure for the standardization of raw material.

Abstract:

Boldo leaves (Boldo folium, from Peumus boldus Mol.) are very frequently used as a medicinal herb in Chile and are exported to many countries to be used in teas or as extracts included in herbal remedies, primarily as an aid to digestion and as a mild sedative. Scientific support for these uses is scanty, and boldine, an alkaloid viewed as characteristic of the tree and present in high concentration in the bark, is extracted by specialized companies and sold as the supposed main active constituent. Consequently, boldine has been the subject of a considerable number of research papers, while some of the other alkaloids present to a greater extent in the leaves have been relatively neglected except when found in large amounts in other species. These studies range from assays of antioxidant activity to anti-inflammatory, antineoplastic and other medical applications. The essential oil, usually containing a large percentage of the toxic ascaridole, was once used as a vermifuge and is now regarded with caution, but is still of interest as a possible natural insecticide, fungicide, antiparasitic and herbicide. The last decade has seen an explosive increase in papers pointing to possible uses of boldo and its constituents. This review attempts to bring these publications together in a comprehensive way with the purpose of stimulating and orienting further research into the useful properties of this Chilean endemic tree.

Abstract:

In the previous utilization of natural resources in forestry as an economic activity, timber exploitation was always the dominant part, and the utilization of other forest products was partly neglected. Nowadays, non-wood forest products (NWFPs) occupy an increasingly significant position in the forestry sector in numerous countries, so that the revenue from their utilization approaches the returns realized by the classical production of timber products. The research performed in Vojvodina, on the sample of six enterprises dealing with NWFP purchase, processing and sale was aimed at the analysis of their market activities to create the image of the market of this group of products. After the study data were analyzed by dynamic statistical methods, the changes in the activities on purchase, the domestic sales and export sales between 2004 and 2010 were presented and future projects were visualized. The research in the form of questionnaire included the quantities of purchased raw materials, the scope of production and sales, both in the domestic, and in foreign markets, as well as the prices of final products. Some species of medicinal plants were purchased on the territories of Croatia and Macedonia, and the purchasing network in the domestic market was remarkably wide and it included predominantly: Nis, Svrljig, Coka, Apatin, Pancevo, Ruma, Boljevac, Kanjiza, etc. The most significant growth was realised in the purchase of a mixture of medicinal plants. Also significant are the purchased quantities of mint, which on average increased by 7.9 t and rose hip by 5.5 t per year. During the study period, the domestic sale of all species of herbal teas and medicinal plants increased significantly, while spices and honey were subject to a fluctuation in sales quantity. Average algebraic deviation of the original final NWFP sale value from the arithmetic mean accounts for 3.48%. With the significance level of 95%, it is estimated that the sale in 2012 will range between 3049.19 and 3343.95 t, under the condition that the sale continues its quadratic trend. Based on the quadratic trend, and with the significance level of 95%, it can be foreseen that the value of export in 2012 will range from 133.01 to 250.07 t. As for the time interval from 2004 to 2010, the average export amounted to 260.07 t, which encompassed primarily medicinal and aromatic plants, spices and honey. During the study period, export decreased on average by 7.03% (20.75 t per year).

Abstract:

The genus Artemisia has recognized medicinal value and its use by humans Dates back to centuries ago. With the appearance of the new coronavirus, end of 2019, several countries have recommended the use of herbal teas consisting mainly of Artemisia. The individual analysis of the constituents of this species is crucial to characterize and optimize its antiSARS-Cov-2 action. We evaluated by molecular docking the inhibitory action of major compounds of the Artemisia genus (Artemisinin, Arteannuin B, Alpha Thujone, P-Hydroxyacetophenone, Fisetin, Cirsimaritin, Capillin, β-Sitosterol, and Quercetin) against three targets namely SARS-CoV-2 main protease (Mp), SARS-CoV-2 receptor binding domain (RBD) and human furin protease (HF protease). The two flavonols, quercetin and fisetin, have the best binding energies with the three targets. Quercetin/Fisetin possesses binding energy of -7.17/-6.9, -6.3/-6.15 and – 5.98/- 5.49 kcal/mol with MP, RBD and HF protease respectively. Their physicochemical properties meet the requirements of an oral active principle and are not toxic according to predictive simulations. Thereby DFT calculation has been used to analyze the electronic and geometric characteristics of these two compounds. The gap energies were also deduced for the stable structure and their reactivity. The abundance of Quercetin in different plants may be another advantage in the use of this bio-compound in the treatment of coronavirus.

Abstract:

Relevance. The demand for medicinal raw materials of Calendula officinalis L. is determined by the high content of pharmacologically significant compounds. Comparison of the most common ornamental cultivars of Calendula officinalis L.) in terms of yield and content of biologically active substances in the raw material helps to identify the most promising cultivars in terms of a set of indicators.Materials and methods.The decorative cultivars Apricot, Art Shads, Fiesta Gitana, Kabluna golden-yellow, Orange King, Orange Balls, Yellow Gitana and Golden Balls, characterized by large inflorescences and terry, were used as prototypes. The cultivar Kalta, widely used for the production of medicinal raw materials, was chosen as a control. The experiments were laid on the experimental plots of the Fruit Growing Laboratory of the Russian State Agricultural University – Moscow Timiryazev Agricultural Academy. Productivity was determined as the total weight of inflorescences harvested during the entire season per unit area. The amount of flavonoids was determined by spectrophotometry. The amount of polysaccharides was determined according to the modified Draywood method. The lutein content was determined by HPLC.Results.To obtain inflorescences we can recommend to use the variety Orange King, which, with a satisfactory yield (0.363 kg/m2), was characterized by a high content of flavonoids (1.2%) and satisfactory (35.9%) extractives and corresponds to the quality of raw materials required by GF XIV. In addition, this variety was characterized by an increased content of polysaccharides (20.3%). The Varieties Apricot and Yellow Gitana were characterized by high productivity (562±49 and 507±41 g/m2, respectively). Their raw materials can be used by production of herbal teas, where the content of flavonoids is not regulated. As sources of lutein, one should pay attention to the ligulate flowers of the varieties Apricot, Fiesta Gitana, Golden balls. In the variety Kabluna, with the maximum lutein content, the proportion of reed flowers in the inflorescence was only 38%. In varieties with large inflorescences, the content of lutein in reed flowers was higher (R=0.685). Large non-double inflorescences will be most productive in this indicator.

Abstract:

AbstractPlants of the genus Phyllanthus, principally Phyllanthus amarus, Phyllanthus urinaria, Phyllanthus niruri, and Phyllanthus tenellus, are used in Brazilian folk medicine to treat kidney stones as well as other ailments, where the latter two species are listed in the Brazilian Pharmacopeia as quebra-pedra (stone-breaker). However, only P. niruri has been shown to be effective in a clinical setting. Nuclear ribosomal internal transcribed spacer (ITS1 – 5.8S rRNA-ITS2), internal transcribed spacer 2, and chloroplasts rbcL, matK, psbA-trnH, trnL, and trnL-trnF were screened for their potential as DNA barcodes for the identification of 48 Phyllanthus taxa in Brazilian medicinal plant germplasm banks and in “living pharmacies”. The markers were also tested for their ability to validate four commercial herbal teas labelled as quebra-pedra. Using the criterion of high clade posterior probability in Bayesian phylogenetic analysis, the internal transcribed spacer, internal transcribed spacer 2, and chloroplast matK, psbA-trnH, trnL, and trnL-trnF markers all reliably differentiated the four Phyllanthus species, with the internal transcribed spacer and matK possessing the additional advantage that the genus is well represented for these markers in the Genbank database. However, in the case of rbcL, posterior probability for some clades was low and while P. amarus and P. tenellus formed monophyletic groups, P. niruri and P. urinaria accessions could not be reliably distinguished with this marker. Packaged dried quebra-pedra herb from three Brazilian commercial suppliers comprised P. tenellus, but one sample was also found to be mixed with alfalfa (Medicago sativa). An herb marketed as quebra-pedra from a fourth supplier was found to be composed of a mixture of Desmodium barbatum and P. niruri.

Abstract:

In general, use of herbal remedies and preparations is on the ascendency in recent times among the general population and especially in young pregnant women, and this may be very dangerous due to adverse effects and interactions with drugs. A survey by the World Health Organization revealed that 70–80% of the world population resort to nonconventional medicines especially, herbal medicines in their primary healthcare. A lot of work has been done on the positive effects of herbs on the human body but very few publications on the potential side effects of consuming crude herbal preparations especially among pregnant women or the awareness of the medical team of this problem. Herbal remedies may come with many adverse effects and potentially serious interactions with some conventional medications. However, little is known about the dangers associated with consumption of herbal remedies by pregnant patients. Herbal medicines like their orthodox counterparts act through some mechanisms to bring about their curative effects in the body, and this usually goes out of order when these remedies interact with chemical drugs as a result of a combination of both by the victims. This is a case study to review the use of herbal medicine products among pregnant women, especially adolescent girls for abortive purposes, and also attempts to discuss some of the dangers associated with the use of herbal medicinal products together with conventional drugs during pregnancy.

As plantas medicinais são definidas como aquelas capazes de produzir princípios ativos que possam alterar o funcionamento de órgãos e sistemas, restaurando o equilíbrio orgânico ou a homeostasia nos casos de enfermidades, assim como outras terapias, fazem parte da chamada Medicina Tradicional, a equipe de Saúde da Família deve atuar de maneira eficaz na orientação da adequada utilização dessa terapêutica complementar, tendo em vista a ampla utilização de plantas medicinais pela população que é atendida nas unidades de Saúde da Família. O objetivo desse estudo é avaliar a importância da orientação dos profissionais de saúde das equipes de saúde da família a cerca do uso da fitoterapia. A pesquisa se trata de um estudo bibliográfico realizado a partir da seleção de artigos, oriundos do banco de dados de Revistas e outras publicações literárias, datadas dos períodos de 2006 a 2014. Os resultados mostram que a utilização de plantas no tratamento de doenças e infecções é uma prática milenar, que continua sendo difundida na atualidade, e que no Brasil essa prática é reconhecida pela organização mundial de saúde, e pelo ministério da saúde, sendo regulamentada por lei, no entanto é importante o apoio e a orientação dos profissionais das equipes de saúde da familia, em especial do enfermeiro, sendo ele considerado uma peça chave nesse processo, pois estes mantém um maior vínculo com a população sendo conhecedor dos costumes e culturas em que a população está inserida.The importance of professional orientation of family health teams a fence phytotherapy useAbstract: Medicinal plants are defined as those capable of producing active ingredients that can alter the functioning of organs and systems, restoring organic balance or homeostasis in cases of illness, as well as other therapies are part of the so-called traditional medicine, the health team Family must act effectively in guiding the appropriate use of this complementary therapy, with a view to wider use of medicinal plants by the population that is served in the Family Health Units. The aim of this study is to evaluate the importance of guidance for health professionals of family health teams about the use of herbal medicine. The research is a bibliographical study from the selection of items, arising from the Journals Database and other literary publications, dating from the period 2006 to 2013. The results show that the use of plants to treat diseases and infections It is an ancient practice that is still widespread today, and that in Brazil this practice is recognized by the world health organization, and the ministry of health, being regulated by law, however it is important the support and guidance of professional teams health of the family, especially the nurse, it is considered a key player in this process, as they maintain a stronger link with the population being knowledgeable of customs and cultures where the population is located.

Abstract:

Bacground/Aim. Cronobacter sakazakii (C. sakazakii) is an emerging food-borne pathogen that has increasingly raised interest among the whole public community and food industry, especially in the production of powder infant formula. It has been isolated from water, sediment and soil. The question is whether this pathogen can be present in herbal teas. Herbal teas are widely used for great number of health problems, as an additional or sometimes only ?medicine? given. The aim of this study was to investigate the presence of C. sakazakii in herbal teas which are traditionally used for all restricted populations, including newborns and immunocompromised infant and adults. Methods. In this study 150 samples of dried herbal teas were tested: Children (Baby) tea (11), Althaea officinalis (7), Sennae folium (4), Mentha piperita (8), Hypericum perforatum (3), Thymus serpyllum (5), Matricaria recutita (6), Fruit tea (18), Black, Green and Rooibos tea (11), Salvia officinalis (9), Arctostaphylos uva ursi (5), Urtica dioica (3), Achillea millefolium (2), Melissa officinalis (4), Cynosbati fructus (3), Flower Herbal tea (3) and 17 different mixtures of tea (48 samples). The presence of C. sakazakii was also investigated in previously positive samples of prepared teas (48 samples) after 2 h, 12 h and 24 h. C. sakazakii was isolated by the use of the official method ISO TS 22964 : 2006 and confirmed with the biochemical test API 20E (Biomerieux-France). Results. The obtained results showed that C. sakazakii was isolated from 48 (32%) samples dried herbal teas. C. sakazakii was not isolated only from 2 (4%) of the 48 tested samples of prepared tea and in 46 (96%) of the samples C. sakazakii remained viable after 2 h, 12 h and 24 h. Conclusion. Herbal teas should be carefully used, especially for infants and immunocompromited people with severe chronic diseases because of the possibility of infection by C. sakazakii. Better control and improve testing as well as new facts about this pathogen are necessarry.

Abstract:

Herbal medicine and health food supplements have become increasingly popular. However, many of these pharmacologically active compounds remain poorly understood. Patients with chronic and life-threatening conditions often use alternative therapies while receiving conventional medical care, and this population is at increased risk for complications and adverse drug interactions due to poor health and complex drug regimens. Patients awaiting or who had received solid organ transplants were surveyed about their use of herbal medicines and health food supplements. Twenty percent of respondents acknowledged experience with these products, which they used to prolong the function of a failing organ or to obtain relief from fatigue and insomnia. Transplant staff often were unaware of their patients' use of these treatments, despite patients' claims to the contrary. The potential for unexpected drug interactions, toxicity, and other adverse reactions resulting from the use of herbal medicines or supplements must be recognized and identified by transplant teams.

Abstract:

Background: Recently, herbal medicine has received much attention in the literature. Several essential oils or plant extracts have been found to have anti-Acanthamoeba properties against trophozoites and cysts of Acanthamoeba spp. Objective: The aim of this systematic review is to introduce anti-Acanthamoeba properties of some essential oils or plant extracts; perhaps the results of this research will be used to prevent and treat infectious diseases. Methods: All published papers in English and Persian databases were systematically searched for some specific keywords to find articles that have influenced plant compounds on Acanthamoeba up to April 2018. Articles related to the subject were selected and studied. Results: A total of 51 articles including 136 experiments (128 in vitro and 8 in vivo) between 1999 and 2018, met our eligibility criteria. Totally, 110 species of plants belonging to 34 families, mainly Lamiaceae (15 plant species) and Asteraceae (13 plant species) were studied against trophozoites and cysts of Acanthamoba in in vitro and in vivo. Most of the plant's species were Citrus (6 species), Allium (5 species), Peucedanum, Piper, Lippia, and Olive (4 species). The most frequently used parts were leaves, aerial parts, flowers, bark, rhizomes, and seeds. Conclusions: Recent studies have shown that many natural compounds have high anti-parasitic properties and low toxicity. Our research team hopes that the information provided in present systematic review can improve new experimental and clinical trials and herbal combination therapy. Further studies are needed to understand the molecular mechanisms in the anti-amoebic reactions of plant species and ocular toxicity of extracts in animal models.
