Chaparral is the creosote bush of the American southwest, used for centuries in Native American medicine. Its active compound, NDGA, is a strong antioxidant with real antifungal and antimicrobial activity, and it has a long history of topical use for skin infections and stubborn fungal problems.
It belongs here with a firm caveat that the book does not spell out. Chaparral taken internally has been linked to serious liver injury, and it has been the subject of health warnings in several countries for that reason. Used externally, in a soak or a wash, it does not carry that risk.
So: external only. Never as a tea to drink, never as a capsule.
