Aim and Objective- The aim of the study is to do physicochemical analysis and preliminary phytochemistry for the drug. Material and Methods- The drug is prepared as per the method mentioned in the classic Siddha literature Siddha Vaithiya Thirattu and in the text Gunapadam Thathujeeva vaghuppu. The drug is subjected to physicochemical analysis such as total ash, loss on drying, total sugar, reducing sugar, fat content, water soluble ash, acid insoluble ash, water soluble extractive, alcohol soluble extractive, microbial load, heavy metal analysis, and preliminary phytochemistry for the drug as per the pharmacopeial laboratory standards of Indian medicine. Result -The drug is free of microbial contamination, the heavy metal such as lead arsenic, mercury, and cadmium are below detectable limit. Alfa toxin are also below the detectable limit. The total ash value is below 3%. Phytochemical analysis shows positive for the presence of alkaloids, tannin, phenols, steroids, flavonoids, carbohydrate etc. Conclusion- Thus the preliminary chemical analysis of a Siddha drug will give fingerprints to the clinical studies.
