PREAMBLE:
Herbal medicine is the most primitive traditional approach to the treatment of diseases and ailments. It is called herbal medicine because it involves the use of plants or plant parts.

Thousands of herbal medicines are used by peoples from every culture and various indigenous medicines are gradually being introduced into modern therapeutics. In developing countries about 80% of the people, especially the rural population, rely on traditional medical remedies for their health care needs. In developed countries, there has been a resurgence of interest in herbal medicines due, to a large extent, on the preference of many consumers for products of natural origin. In addition, manufactured herbal medicines from their countries of origin often follow in the wake of migrants from countries where traditional medicines play an important role.
