History of herbs & its introduction

The term “medicinal plant” includes various types of plants used in herbalism (“herbology” or “herbal medicine”). It is the use of plants for medicinal purposes and the study of such uses.

Plants have been used for medicinal purposes long before the prehistoric period. Ancient Unani manuscripts Egyptian papyrus and Chinese writings described the use of herbs.  Evidence exists that Unani Hakims, Indian Vaids, and European and Mediterranean cultures were using herbs for over 4000 years as medicine. Indigenous cultures such as Rome, Egypt, Iran, Africa, and America used herbs in their healing rituals, while other developed traditional medical systems such as Unani, Ayurveda, and Chinese Medicine in which herbal therapies were used systematically.

Traditional systems of medicine continue to be widely practiced on many accounts. Population rise, inadequate supply of drugs, the prohibitive cost of treatments, side effects of several synthetic drugs, and development of resistance to currently used drugs for infectious diseases have led to increased emphasis on the use of plant materials as a source of medicines for a wide variety of human ailments.

Among ancient civilizations, India has been known to be a rich repository of medicinal plants. The forest in India is the principal repository of a large number of medicinal and aromatic plants, which are largely collected as raw materials for the manufacture of drugs and perfumery products. About 8,000 herbal remedies have been codified in AYUSH systems in INDIA. Ayurveda, Unani, Siddha and Folk (tribal) medicines are the major systems of indigenous medicines. Among these systems, Ayurveda and Unani Medicine are most developed and widely practiced in India.

Recently, WHO (World Health Organization) estimated that 80 percent of people worldwide rely on herbal medicines for some aspect of their primary health care needs. According to WHO, around 21,000 plant species have the potential for being used as medicinal plants.

As per data available over three-quarters of the world population relies mainly on plants and plant extracts for their health care needs. More than 30% of the entire plant species, at one time or other, were used for medicinal purposes. It has been estimated, that in developed countries such as the United States, plant drugs constitute as much as 25% of the total drugs, while in fast-developing countries such as India and China, the contribution is as much as 80%. Thus, the economic importance of medicinal plants is much more to countries such as India than to the rest of the world. These countries provide two-thirds of the plants used in the modern system of medicine and the health care system of the rural population depend on indigenous systems of medicine.
