Chaparral is an herb from the creosote bush, a desert shrub native to southern areas of the United States and northern regions of Mexico. It’s also called Larrea tridentate, chaparral, and greasewood and has been used as an herbal medicine for centuries. Chaparral has bright yellow flowers and resinous, evergreen leaves that can be described as pungently aromatic. Chaparral leaf is typically used in topical applications but can also be tinctured, infused in oil or honey, or brewed into tea.
