This document discusses Ayurvedic formulations known as Asava and Arista. Asava and Arista are medicinal preparations made by soaking herbs in a solution of sugar or jaggery that then undergoes fermentation to produce alcohol, extracting active principles from the herbs. The key differences are that Asava is prepared without boiling the herbs, while Arista involves boiling. Standardization of these formulations ensures a defined content of constituents with known therapeutic activity. The document outlines the methods of preparing Asava and Arista, including use of fermentation pots, addition of herbs, and precautions to ensure cleanliness during the process.
