A Review of Pharmacological Action of Certain Herbal Drugs

Abstract

Plants are fundamental to almost all life on earth, providing protection and sustenance for organism ranging from a microorganism to a large animal even too certain categories of plant species. Plants can be considered as chemical factories that have been evolving their biosynthetic pathway programmes over the last decades. During this evolution, plants have synthesized an array of compounds whose structural diversity is often beyond the imagination of even the most imaginative organic chemists. Plants appear to have evolved the chemical pathways to produce many chemical compounds, which are responsible for many pharmacological activities resulting to medicinal potentiality of that plant species. Present communication reviews the pharmacological actions of three important herbal drugs used in a number of herbal formulations, along with their taxonomy and phytochemistry.
