A research conducted for the stability of ayurvedic preparations involving medicated ‘ghee’ (grhita) and oil (taila), conducted at the department of Rasa Shastra, BHU, has fixed the shelf-life of such preparations as a maximum of two years.
Consumers need to note that only ‘asavarishta’ (herbal liquid preparation) and ‘bhasma’ (metallic-herbo formulations) have no expiry date and can be used even after two years of manufacturing.
This comes in the light of a number of ayurvedic preparations involving medicated ghee and oil, including Mahanarayana Taila with analgesic properties are used in Panchakarma procedure and most of them have a shelf-life of 18 to 24 months. According to the Pharmacovigilance Centre for North Region, the rule 161 (B) of Drugs and Cosmetics Act, 1945 has made it mandatory to print the manufacture and expiry date of all ayurvedic, siddha and unani ( ASU) drugs from April 1, 2010 onwards.
