Chris Kilham, Alternative & Complementary Medicine, answeredBecause multiple constituents of holy basil have been shown to combat stress, an effective supplement must provide each of these key active components at therapeutic dosages. In particular, the supplement should be standardized for eugenol, caryophyllene, and triterpenoic acids, such as ursolic and oleanolic acids. As these constituents differ significantly in their chemical structure, alternate extraction methods are needed to obtain beneficial levels. It is important to look for a dietary supplement that utilizes multiple extracts of holy basil, such as alcohol extracts, supercritical (or CO2) extracts, and distillation extracts, to provide the most complete supplement.
