Toxicity and toxicology of medicinal plants

The poisonous substances in plants are mostly alkaloids, glycosides, organic acids, resins, resinoids, and mineral compounds. A poisonous plant is a plant that can be harmful or fatal to humans or other animals if touched or eaten in sufficient quantity. If used in small amounts and in the right proportion, these plants can be used as herbal medicines with medicinal properties. The beauty of these plants hides their toxicity. Scientific understanding of plant toxins and their effects has greatly increased. Poisonous plants that cause serious problems or even death are considered as "plant biological weapons". Knowledge about poisonous plants is still insufficient and it is very important to identify some species that cause poisoning and death in humans. The purpose of this article is to provide information about poisonous plants, existing toxic compounds and symptoms when consumed, as well as their medicinal uses.
