Extracts are typically categorized by the solvent used to make them and/or by their form. Some of the more common solvents that are used include water, alcohol, glycerin, and vinegar. The inherent qualities of each of these solvents will attract different phytochemicals in an herb. Watery extracts made by infusion or decoction are used as teas, rinses and the base for syrups and other products.
