Interpretive Summary: Eriodictyon, which are commonly referred to as “Yerba Santa,” are plants which are native to the American Southwest and northern Mexico. Traditionally, the plants have been used to treat various ailments, in particular, respiratory conditions. Despite having a rich history of traditional use, many members of the genus have never been fully chemically characterized. In addition, a comprehensive quantitative investigation of the primary constituents of the species has not been reported. This investigation was initiated in colaboration with American Herbal Pharmacopoeia (AHP) to develop analytical methods for the chemical characterization and quantitative determination of the primary constituents in yerba santa (Eriodictyon spp.). The results of this study are included in the Analytical Section of the yerba santa Monograph and Therapeutic Compendium, which is the first yerba santa Monograph and Therapeutic Compendium released in any pharmacopoeia.
