Since time immortal, people have been using herbs in their surroundings for remedies to cure various diseases. The history of medicine in India- the holy land of Ayurveda, can be traced to the remote past. The earliest mention of the medicinal use of plants is found in the Rigveda, perhaps the oldest repository of human knowledge, having been written between 4500 and 1600 BC. The classical texts of Ayurveda are abound with information on medicinal plants, Susruta Samhita which was written not later than 1000 BC, contains  a comprehensive chapter on therapeutics and Charak Samhita written about the same period, gives a remarkable description of the 'Materia Medica' as it was known to ancient Hinduas.

  Ayurveda (1500 BC) is considered as science of life, this very ancient and typically Indian Classical System of Medicine treats complete health to be a blend of physical, mental, social moral and spiritual well being.

  India is one of the richest countries as far as biodiversity of medicinal plants is concerned. About 30,000 species of higher plants are used in Traditional System of Medicine the world over. In India alone an estimated 7500 species of higher plants are used as medicine in folk traditions. As India is a large country having many ecological and climatic zones with their corresponding biodiversity, the plant varies from region to region as does its use.

Break-up by parts used :



Many medicinal plants mentioned in ancient texts baffle recognition and identification, as it was not possible to state with certainty from the description given in the literature whether the plant in actual use as drug is the one described. Verbal description given in old books are inadequate to the botanist for identifying the plants. There had been a good deal of confusion in vernacular names. This was due to lack of color photography at that time.

The research and survey work pertaining to medicinal plants , their identification and color photography were carried out by the Author. This web site will be useful to Ethno botanists, Ayurvedic Physicians and Research workers in this field.
