Abstract
The plant kingdom is as diverse as the animal kingdom. There are several species that are yet to be discovered or whose therapeutic properties are undiscovered. Many of the species may have become extinct before they were discovered. This work investigates the function of herbalism in the context of its history and significance. The diversified geographical terrain sustaining several indigenous species of plants of medicinal importance is described. The usage of herbal practices and several techniques are highlighted. The toxicity of plant-based medicines and the progress of several clinical trials are also discussed.
