PHARMACOBOTANICAL STUDIES ON ‘SHVET SHARPUNKHA’ – A COMPARATIVE DIAGNOSTIC ACCOUNT OF TEPHROSIA VILLOSA PERS. AND T. PURPUREA (LINN.) PERS. FORM ALBIFLORA S. R. PAUL et. R. C. GUPTA

Two kinds of ‘shapunkha’, the ‘Shvet’ (white) and ‘Rakta’ (red) are described in some of the Ayurvedic texts and the former is reported therapeutically more effective. Some of the Ayurvedic physicians use T. villosa Pers. as ‘Shvet sharpunkha’ due to its persistently villous silky white parts. While others have advocated white colour of flowers as main feature for distinguishing “Shvet sharpunkha’. A white flowered form of Tephrosia purpurea which is found in association with red or purple flowered ones is reported by us as T. purpurea (Linn.) Pers. Form albiflora S. R. Paul et R. C. Gupta. In the present work, however, detailed comparative pharmacognosy of all vegetable parts of T. villosa and T. purpurea f. albiflora have been carried out. Also the study reveals that two species exhibit great similarity in their macro – an microscopical feature.
