Naturopaths and other gurus of “alternative medicine” love to tout the benefits of traditional herbal medicines.

For instance, Aviva Romm—a Yale-educated doctor who publicly defended Gwyneth Paltrow’s lifestyle site Goop then later called it a “caricature of everything alternative health for women”—sells her own line of unproven herbal remedies.

Billionaire Susan Samueli—who donated $200 million dollars alongside her husband so the University of California, Irvine, could open an “integrative” medicine program—promotes homeopathy, naturopathy, and runs an active consulting practice versed in Chinese herbs.

In Taiwan, for instance, 78 percent of 98 liver tumors sampled displayed a pattern of mutations consistent with exposure to herbs containing aristolochic acids (AAs).

These flora tend to come from the genera Aristolochia (e.g., birthwort, pipevine) and Asarum (wild gingers).

Studies done on products found to contain AAs show that their levels are extremely variable and can sometimes be very high.
