“Dhava” is unanimously ascribed toAnogeissus latifolia Bedd. which is a large deciduous tree having most of the curative properties as credited to its stem-bark, root and leaves. A detailed pharmacognosy of the stem-bark and the root of the above species has been dealt with in the present paper. The study revealed that while the stem-bark is characterised by its short-complete fracture, exclusively narrow phloem rays and small irregular concentric phloem fibre strands; the root is identified for its bark having fracture laminated, some considerably broad phloem rays in outer part of phloem, large regular concentric phloem fibre strands and the wood with diffused vessels, xylem parenchyma typically aliform to confluent with some scattered cells and xylem rays exclusively narrow. The fluorescence analysis of drug powders and their behaviour on treatment with different chemical reagents, percentage extractives and ash values, preliminary phytochemical studies includingTLC patterns of various extractives have also provided useful parameters to distinguish these plant-parts and check the adulteration.
