Ayurveda, the science of life, dates back to the days of Charaka Samhita and Sushruta Samhita (1200 AD). A balance between the two is a recurring theme of Ayurveda and, to achieve this goal, medicinal plants have been accepted for centuries (Chopra et al., 1956). Medicinal plants are used for the treatment of human diseases since ancient times. The Sacred Vedas in India between 3500 BC and 800 BC make many references to medicinal plants which is one of the remotest works in traditional herbal medicine Vrikshayurveda, compiled by Surapala even before the beginning of ancient India and the Christian era formed the basis of medical studies. The two memorable works of Charaka Samhita and Sushruta Samhita (400-500 AD) are called the "Golden Age" of Indian culture (Jain, 1968).
