ABSTRACT
Pharmacognosy is the study of naturally occurring biological substances, principally those derived from plants that find use in medicine. The word "Pharmacognosy" is derived from the Greek "Pharmacon," "a drug" and "gignosco," to acquire knowledge of. It is closely related to both botany and plant chemistry and both originated from the earlier scientific studies on medicinal plant. The plant kingdom still holds many species of plants containing substances of medicinal value which have yet to be discovered large number of plants constantly being screened for their possible pharmacological value. The plant Chandrashura is being used for the treatment of Amavata, Sandhivata, and Katishula successfully. Here, an attempt is made to study the plant pharmacognostically; the part taken for study is the seed. Diagnostic features of seed and seed powder were also worked out and the details were presented.
