Background: Ayurveda deals with minerals, metals, and herbs in therapeutics that have been classified into several groups. Among them, Yava kshara (alkali preparation made with the whole plant of barley (Hordeum vulgare L.) is a type of Kshara (alkaline preparation) that is useful in various diseases. Addition of cotton wick in the procedure seems to facilitate the process and increase the yield. However, its actual utility is not yet reported. Objective: The aim of this study was to develop a standard manufacturing procedure (SMP) of Yava kshara by using the cotton wick method. Materials and Methods: The method of Ayurvedic Pharmacopoeia of India was followed with addition of cotton wick to decant the liquid layers. Yava panchanga (whole plant—root, stem, leaf, flower, and seed of H. vulgare L.) was collected from the fields of Derwala, Jhunjhunu, Rajasthan and authenticated at the National Institute of Science Communication and Information Resources (NISCAIR), New Delhi. Plant was dried and converted into ashes, washed for three times, and the process of decantation by cotton wick method was repeated to obtain alkaline preparation. Results: An average of 11.72% w/w Yava kshara was obtained from the first filtrate. The second and third filtrates yielded 2.9% and 1.26%, respectively. Conclusion: Addition of cotton wick facilitates decanting process and obtaining clear liquids. The yield is comparatively higher than the earlier reports.
