Context: With increasing popularity, the quality of medicines has become an important issue. Shelf life is an important component that is mandatory to be displayed on the label of all medicinal products. This is also applicable to Ayurveda; thus, it becomes essential to establish shelf life of formulations that are being marketed and used in therapeutics. The shelf life of Nishamalaki churna, a frequently used formulation for the management of diabetes, is not reported till date. Aim: The aim of this study is to evaluate the shelf life of Nishamalaki churna through the accelerated stability study. Methods: Physicochemical parameters were measured at the temperature of 40 ± 2 °C and the relative humidity was 75 ± 5%. The analysis was repeated at the intervals of 1, 3, and 6 months, and the average 10% degradation time was calculated and extrapolated to find the shelf life. Results: Shelf life of Nishamalaki churna is found to be 3 years 7 months. Conclusion: The Gazette of Government of India prescribes a limit of 2 years as the shelf life for churnas (powdered formulations). The observations of the current study reveal that Nishamalaki churna is stable for a longer duration than the prescribed period of 2 years when stored appropriately in well-closed containers.
