Abstract

Valu decoction is a classical formulation mentioned in authentic Traditional textbooks. It is predominantly categorized into two types, namely Valu decoction I and Valu decoction II. While the method of preparation remains consistent for both methods, the ingredients employed differ. The decoction is primarily utilized to address postpartum complications. It consists of twelve plantbased ingredients and sand of river or stream. The present study primarily focuses to lay down analytical standards for Valu decoction I. The selection of quality and correct ingredients was the first step in standardizing herbal decoction. The relevant plant species were identified, and their validity confirmed using phytochemical investigation. The study was conducted to reveal the variations in organoleptic parameters (color, odor, and taste), physico-chemical parameters (pH, specific gravity, refractive index and brix value). Refractive index evaluates purity of preparation was found to be 1.33. pH value which evaluates the quality of the drug was found to be 5.18. Alkaline pH favors high microbial contamination of the herbal preparations, but it is slightly acidic in nature. Brix value use for evaluation of how much dissolved sugar is in a liquid solution was found to be 1.23. Foaming ability index was used to determine the foaming ability of aqueous decoction of herbal material was found to be1.36. Specific gravity is an evaluation parameter affirming wt/ml should always be more than carrier solvent (water). Notably, the majority of phytochemical constituents, including saponins, alkaloids, flavonoids, tannins, and steroids, were present in significant quantities across the samples.
