C. ternatea have reported number of pharmacological activities such as nootropic, anxiolytic, anticonvulsant, sedative, antipyretic, anti-inflammatory and analgesic. In present study pharmacognostic investigation of leaves was carried out by using morphological, microscopic and physicochemical parameters. It was found that leaves are odd pinnately compound, with obovate in shape, entire margin, Emarginate tip and symmetrical base, green in color, bitter in taste, with characteristic odor. Microscopic study reveals that presence of Upper and lower epidermis consists of single layer of cells covered with thick cuticle. Covering trichomes are present on both the surfaces.

The moisture content found to be 12.5±2.57. Water soluble and alcohol soluble extractive value found to be 25.2 and 18.4 respectively.
