The process of botanical extraction, drawing specific compounds from raw plant material, can be achieved by many methods. Solvent extraction may be the most popular, but there are many other methods ranging from older to newer and from simple to more complex. Choosing the right extraction method for a given ingredient or product requires consideration of the characteristics of each available method. There are several resources available to help inform and guide extraction, including USP standards, ABC monographs and books, and AHPA guidelines on solvent residues.
