The creosote bush — the smell of desert rain. A potent antioxidant shrub of Southwestern folk medicine, recorded here with a serious warning: internal use has caused liver failure, and it belongs in the cabinet as a caution, mainly for external use.
Honest herbalism means naming the herbs that can hurt you. Chaparral's reputation as a cure-all 'blood cleanser' has circulated in alternative-health spaces, including ones marketed to Black communities; the responsible service is to document its real topical value and its real internal danger plainly.
Chaparral is one of the most powerful antioxidant plants known — its NDGA (nordihydroguaiaretic acid) is a potent free-radical scavenger and was once a commercial food preservative. Traditionally the desert peoples used it (mostly externally) for skin conditions, wounds, sores, and as a wash for inflammation, and internally as a strong 'blood purifier' and anti-parasitic tea. HOWEVER: internal chaparral has caused multiple documented cases of acute hepatitis and liver failure, some requiring transplant, and the FDA has warned against it. This entry therefore frames chaparral honestly — a remarkable topical antioxidant and skin herb, but NOT a safe internal medicine. For the skin (eczema, sores, fungal complaints) a salve or wash carries the benefit without the liver risk.
Topical only is the safe path: infused oil, salve, or strong decoction used as a wash or compress for skin and wounds. Internal use is not recommended due to hepatotoxicity. The resinous leaves are intensely bitter and aromatic.
