nani System of Medicine (USM) is based on the drugs originated from plants, animal, and minerals. There is a need to maintain their purity, quality and safety by subjecting the finished products to rigorous scientific testing and to lay down pharmacopoeial standards for both Single and Compound drugs. Standardization of drugs is necessary especially in case of compound formulations to maintain the quality control and to identify the adulterated drugs. So Unani formulation namely Habbe Mubarak (HM) was subjected to standardization which is indicated in Hummae Ajamiya (malarial fever) and as Dafe Tap (antipyretic). The present study was designed to establish the physicochemical standards which can be used for future reference. The physicochemical standardization of HM includes organoleptic characters, weight variation of pill, uniformity in diameter, hardness test, friability test, pH, moisture content, loss of weight on drying, ash values, water and alcohol soluble matter, extractive values, disintegration time, thin layer chromatography (TLC) and total alkaloidal estimation. The findings of physicochemical study of the lab samples

of HM may act as reference for quality control.
