Pharmacognostic standardization of polyherbal formulations is important step in order to explain the quality of formulation. The present research work reports pharmacognostic standards of polyherbal formulation Jwarnashak Panch Kashya which contains five herbal drugs (Tinospora cordifolia, Swertia chirata, Fumaria parviflora, Zingiber officinale and Cyperus rotundus) in equal proportion. Traditionally, Jwarnashak Panch Kashya is used as antipyretic. Various pharmacognostic standards of Jwarnashak Panch Kashya such as ash values, extractive values, moisture content, foreign organic matter, swelling index, foaming index, tannin determination and volatile oil content were generated using standardized methods. Phytochemical screening showed presence of fats, triterpenoids, alkaloids, steroids, anthraquinone glycosides, cyanogenetic glycosides, cardiac glycosides, flavonoids, saponins, coumarins, tannins, proteins and carbohydrates in plant. Thin layer chromatography fingerprint profile of n-hexane, chloroform and methanol extracts showed five, six and eight spots, respectively, using optimized solvent system.
