Present study deals with the pharmacognostical study of root and stem of Naregamia alata Wight & Arn for its identification and to distinguish it from the co-existing weeds and adulterations with the help of its macroscopic and microscopic features. From the microscopic observation the thin roots have a thin, less prominent, superficial, wary but continuous periderm and the thin roots has wide, undulate, fissured prominent periderm. In thin stem, the cortex fairly wide comprises four or five layers of dilated, thin walled compact parenchyma cells and thick stem, the cortex has five or six layers of thin walled parenchyma cells.
