Apart from being an important drug in the Unani as well as other herbal systems of medicine, the plant has assumed great significance due to recent findings of its anti cancerous, antimicrobial and antiinflammatory activities. In order to provide criteria and to set standards for ascertaining genuineness and quality of the drug, pharmacognostical study has been carried out on the dried sample of the drug. The work describes in detail morphological and anatomical features, study of the powdered drug and its analysis under UV light, qualitative determination of chemical constituents, some physico - chemical parameters and results of thin layer chromatography. The salient features of the drug have been discussed.
