Indigenous knowledge behind traditional practice of herbs is like crude diamond, hardest but without shine and not acknowledged and accepted as "Diamond" by the people. Today an artificial shining stone, well packed, aggressively marketed and supported by strategic advertisement is the biggest threat to the existence of real Diamond. If this continues then this phenomenon of endangered indigenous knowledge of tribal will become extinct and needless to discuss, we the human being will be deprived of the real essence and hence the biggest looser. It is important to know that it requires $ 1.5 billion and 10-15 years to develop a new drug, whereas, the development of new drug through traditional herbal knowledge and tribal healers could be much shorter and needless to discuss "cost effective". The whole book moves around the fulcrum of traditional herbal knowledge of Indian Tribesmen. It is the finest attempt to explain the traditional herbal knowledge of Indian tribal regions which are very different in terms of forest, vegetation, cultures, and beliefs. Nevertheless, equally competitive so far age old medicinal practices are concerned. The book deals with about 210 important medicinal plants used by the traditional herbal healers in India.
