Other Medical Connections: Cancer researchers first became interested when an 87 year old man cured a facial cancer by consuming chaparral. Scientists at the University of Nevada investigated the activity of NDGA and found that it was a potent inhibitor of mitochondrial enzymes, which in turn inhibits cancer growth. While no clinical data exists to support using chaparral for cancer therapy, thousands of testimonials credit it for tumor remissions and complete cures. Other medical evidence indicates chaparral is an anti-inflammatory, and antimicrobial agent and a possible treatment for asthma. Research continues to uncover it’s mode of action and other potential therapeutic uses.
