Sources for a history of plant sciences in India: The Rg-vedic (Rigvedic) Soma plant

A brief survey of views thus far expressed in regard to the identification of the Rg-vedic Soma plant is given. In the present study, the problem has been approached from the point of view of the effects produced by Soma drinking rather than from the morphological aspects of the plant. A comprehensive report on the later Soma-substitutes is also provided.
