Though remarkable success have been achieved in the discovery and development of various drugs for the treatment and management of several ailments, there is still need for more discoveries. This is due to the reason that some of the drugs currently in use posseses one or more of the following drawbacks (i) high toxicity level (ii) increase lose of effectiveness or low efficacy (iii) costly or (iv) inaccessable. Herbs have now become the main stream for drug discovery and development. Conservative estimate have revealed that there are over 250,000 higher plant species, and only a minute proportion have been screened exhaustively for their possible therapeutic properties. Atleast, over 120 unique pharmacological substances derived from plants are currently being used as drugs in various countries in the world. Apart from the direct use of plant derivatives as therapeutic agents, they can also serve as models for the design, synthesis or semisynthesis of other therpeutic agents. In conclusion, herbs are a reliable source for more discovery and development of new drugs. The scientific community should therefore harness this resource by improving research on it.
