Abstract:
Plants with medicinal properties are used all over the world for disease treatment. Poisonous phytochemicals (toxins) in some or all parts of these medicinal plants are the causeof the toxic effects exerted by some medicinal plants. The objective of this paper is to provide a review on themedicinal effects and toxic properties of the seeds of some medicinal plants (Abrus precatorius, Datura metel, Physostigma venenosum and Ricinus communis) used in ethnomedicine in Nigeria by harvesting secondary data from standard online sources. This review gives collective reports on the medicinal propertie

Abstract:
Medicinal plants have been documented as an important source for discovering new pharmaceutical molecules that have been used to treat serious diseases. Strikingly, previous reports stated that natural products and their derived compounds exhibit lesser side effects and improved efficacy than other synthetic counterparts. Physostigmine, a parasympathomimetic plant alkaloid isolated from the West African perennial shrub Physostigma venenosum, it shows a narrow therapeutic index and a short life span, despite its ability to penetrate the blood-brain barrier (BBB).

Abstract:
Insect pests infestation is one the major problems associated with the production of maize in many Sub-Saharan Africa including Nigeria. Control of these pests by farmers has been vastly through the use of synthethic chemical pesticide which possesses lots of threats to human health and environments. A study was conducted at the University of Calabar, Nigeria, to assess the effectiveness of essential oils (EOs) derived from four plant species against Sitophilus zeamais Motschulsky, commonly known as the maize weevil. The EOs were applied in varying concentrations (2.5, 5, 7.5, and 10 µl/l) arr

Physostigmine, or eserine, is an alkaloid found in the Calabar bean (eséré), Physostigma venenosum (Balfour). The scientific discovery of physostigmine played a pivotal role in our understanding of chemical neurotransmission and the emergence of pharmacology as a science. The Efik people of Old Calabar, in present day Cross River State of Nigeria, used the bean as an ordeal poison to determine if persons accused of certain allegations such as witchcraft were guilty or innocent.

The prevalence of individual civilisational diseases has been constantly increasing in recent years. Their occurrence is related, among other factors, to changes in lifestyle (stress, low levels of physical activity, low-quality diet), increasing urbanisation and industrialisation (environmental pollution). Lifestyle- dependent diseases include type 2 diabetes and Alzheimer's disease which is not only related to lifestyle - one of the main risk factors is age.

The treatment of neurological diseases has evolved to include neuroactive alkaloids isolated from naturally occurring phytochemical sources. While some of these compounds have gone on to clinical use themselves, others have inspired the development of synthetic analogs, which might possess greater potency or better pharmacological features than the natural product itself. One such naturally occurring alkaloid, physostigmine, which is found in the Calabar bean plant Physostigma venenosum, has been demonstrated to be a potent cholinesterase inhibitor.
