Brihatyadi Kwatha (BK) a popular Ayurvedic polyherbal decoction for urinary problems is a formulation of five roots - Salaparni, Prisniparni, Brihati, Kan-takari and Gokshura. Sahasrayoga, adopting Ashtanga Hrdaya describes the drug ratio as 1:1:1:1:2 respectively, but some formularies consider ratio of the last drug as 4 and 8. The source of Prisniparni is Desmodium gangeticum (L.) DC in Kerala where as it is Uraria picta (Jacq.)DC in north. This diversity in source plants and proportion of ingredients can create variability in product standards. Currently there is no specific standard prescribed for BK in Ayurve-da Formulary of India. Hence, this study is taken up as step towards standard-isation of Brihatyadi Kwatha. The study aims to determine characteristic Pharmacognostic and Physicochemical parameters and TLC profile of ingredi-ents as well as the end product - two variants of Brihatyadi Kwatha, to set standards. Ingredient drugs of BK were subjected to macroscopic, microscop-ic, physicochemical analysis. Ingredients and products were subjected to Thin Layer Chromatography
Characteristic features of the analyses were recorded. Rf values in the TLC profile demonstrated presence of all ingredients of BK. The findings may be useful as standards for quality control of Brihatyadi Kwatha.
