A common myth exists among people that Ayurvedic medicines do not have an expiry date, but it is not true. Concept behind expiry means that after a certain period, the substance that is used as medicine undergoes changes, which make it ineffective. That period is known as expiry date or shelf life in modern system of medicine. This concept was described in 14th century by Acharya Sharangdhar as Saviryata Awadhi in his textbook Sharangdhar Samhita. Recent development in the field of Ayurvedic pharma industries has reestablished old principles through evidences. Among the description of all five primary dosage forms, Churna (powder) has been considered in this study. There are numerous factors that affect its shelf life, which have been discussed in this study. Based on that, we conclude that by improving storage conditions, adding additives and preservatives, degradation of Churna can be checked.
