Larrea tridentata
Sonoran Desert shrub used by Native Americans and Mexican communities for pain, infections, and cancer; highly controversial due to hepatotoxicity risk.
Gobernadora (Larrea tridentata) is a Sonoran Desert shrub traditionally used by Native Americans and Mexican communities for arthritis, infections, and cancer support, but its internal use is highly controversial due to hepatotoxicity. Its primary active compound, nordihydroguaiaretic acid (NDGA), exhibits antioxidant, antimicrobial, and anti-inflammatory properties, while flavonoids and lignans contribute to its antiproliferative effects. Modern evidence (Level C) supports topical applications for dermatitis and limited short-term internal use, but chronic ingestion poses serious liver risks.
NDGA acts as a potent lipoxygenase and cyclooxygenase inhibitor, reducing leukotriene and prostaglandin synthesis, thereby exerting anti-inflammatory effects. It also scavenges reactive oxygen species and chelates metal ions, contributing to antioxidant activity. Flavonoids like quercetin and kaempferol modulate NF-κB and MAPK pathways, while lignans such as larreatricin induce apoptosis in cancer cells via caspase activation and mitochondrial dysfunction. Antimicrobial effects involve disruption of bacterial cell membranes and inhibition of efflux pumps.
