Herb Pharm Chaparral Extract. Herb Pharm prepare their Chaparral Extract from the dried leaf flowers of Larrea tridentata shrubs which are Custom Wildcrafted in their wild native habitat in the deserts of southwestern America. Herb Pharm's Chaparral is never fumigated or irradiated. What Chaparral Herb Is: This is one tough shrub, able to survive without water for quite some time in its native southwestern desert areas of the United States. When the rain arrives, it flourishes. Its small yellow flowers bloom, and its leaves weep a sticky resin that smells like creosote or tar. (That's why locals in the desert call it creosote bush.) In Mexico, It's called hediondilla, which translates as "little stinker." Medicinal Properties: Certain phytochemicals in chaparral oppose free radical oxidation, quell spasms, and kill bacteria. The lignans destroy amoebas and fungi.
