Physicochemical evaluation of himasagara taila

Abstract

Context: Taila is considered as the drug of choice in vata vikaras. Taila can be used both internally and externally. Sneha is prepared in three different pakas (processed oil) - mrdu (first stage of processed oil), madhyama (second stage of processed oil), and khara (third stage of processed oil) for administration in different condition. Himasagara taila is good for vata disorders and is mentioned in Bhaishajya ratnavali. Aims: The aim of the study was to analyze the physicochemical parameters of himasagara taila. Materials and Methods: Himasagara taila was prepared in the Department of Rasashastra and Bhaishajya Kalpana, Amrita School of Ayurveda as per the reference. The obtained product was subjected to organoleptic and physicochemical analysis. Results: Physicochemical parameters obtained are loss on drying - 0.45%, refractive index at 30°C = 1.468 and at 40°C = 1.464, acid value - 8.95 mg/g, free fatty acid 4.5018%, saponification value 218.39 mg/g, ester value - 209.45 mg/g, unsaponifiable matter - 3.62%, peroxide value - 8.55 meq/kg, specific gravity at 30°C 0.915, and viscosity at 30°C (by Brookfield viscometer) - 54 cp. Conclusions: The values obtained after analysis were found to be within the permissible limits of general taila kalpana. The obtained values can be taken as standard parameters for future preparation.
