This document discusses Ayurvedic formulations known as Asava and Arista. It begins by defining Asava and Arista as medicinal preparations made by soaking herbs in a solution of sugar or jaggery that undergoes fermentation to produce alcohol, extracting active principles and allowing long preservation. It then describes the methods of preparing Asava, where herbs are soaked in water without boiling, and Arista, where herbs are boiled. General precautions for production are outlined. The key characteristics are that the filtered final products have alcohol that acts as a preservative while delivering active principles.
