BACKGROUND: Gomaya Swarasa (Cow dung expressed juice) is one of the commonly used materials in Ayurvedic Pharmaceutics. Available Ayurvedic pharmacopeias provide inadequate information about the process of preparation of Gomaya Swarasa. This article deals with the preparation of Gomaya Swarasa and its preliminary pharmaceutical evaluation. MATERIALS AND METHODS: Fresh Gomaya (cow dung) obtained from Bos primigenius indicus species was used to prepare Gomaya Swarasa by using two different methods: first, by keeping a piece of clean muslin cloth inside the Gomaya for one Yama three hours and extracting the Swarasa by squeezing it. In another method, water was added, in three different ratios: half, same, and double the quantity with freshly collected Gomaya and properly mixed, set aside for three hours, and finally kept in a muslin cloth and tied like a Pottali for twenty four hours. The Swarasa obtained were collected on the following day; the yield, consistency, specific gravity, and pH were analyzed following standard methods of API. Each method was repeated three times. RESULTS: No yield was obtained in the first method of extraction. The maximum quantity of Swarasa obtained was 74% in 1:2 (Gomaya: water) ratio dilution, followed by 37.4% in 1:1 ratio dilution. The consistency of Swarasa obtained in 1:1/2 dilution was very thick with an average specific gravity of 1.009, whereas that in 1:1 dilution is somewhat thick but more liquid in nature with an average specific gravity of 1.006. The Swarasa obtained from 1:2 dilution is thin and of liquid consistency with an average specific gravity of 1.004. The maximum average pH obtained is 7.56 in 1:1/2 dilution, and the minimum average pH is 6.28 in 1:2 ratio dilution. CONCLUSION: Gomaya Swarasa prepared by adding the double quantity of water can be taken as a better method of preparation in terms of yield, consistency, and specific gravity. However, the pH of Gomaya Swarasa from this method was slightly acidic (average pH-6.28) in nature. Thus, Swarasa from 1:1 dilution can be taken as standard in terms of pH, where the other factors such as yield, consistency, and specific gravity are also acceptable. The Swarasa obtained from different dilutions can be used in pharmaceutics based on its need in terms of pH, yield, consistency, and specific gravity.
