SHORT PITCH (AS SOLD)

A folk-remedy herbal tonic and caustic paste, passed down in the Hoxsey family and marketed from 1924 as a normalizer of the body's chemistry that could cure internal and external cancer without surgery, radiation, or x-rays.

THE ACTUAL EVIDENCE

The National Cancer Institute reviewed 77 case reports Hoxsey submitted in 1946 and concluded that none of them met its criteria for scientific evaluation. The government's Food, Drug and Cosmetic Act enforcement action against the Hoxsey Cancer Clinic went to trial and reached the Fifth Circuit Court of Appeals (opinion reprinted at Md State Med J 1952;1(11):560, PMID 13001332), which found the evidence established that specific individuals named as cured in Hoxsey's promotional booklet had not in fact been cured. A follow-up study of 39 patients who had taken the Hoxsey herbal treatment (cited in the American Cancer Society's review) found ten had died after an average of 15 months and only six were disease-free after 48 months, with 23 never completing the study. The American Cancer Society and Memorial Sloan Kettering both conclude no objective evidence supports the tonic's efficacy against cancer; the escharotic paste does destroy tissue on contact, but non-selectively, burning healthy skin along with any tumor rather than selectively targeting malignant cells. The FDA banned interstate sale of the treatment in the United States in 1956 and forced Hoxsey's American clinics to close by 1960, but the same formula has been sold continuously since 1963 at the Bio-Medical Center in Tijuana, Mexico, opened by a former Hoxsey nurse; Memorial Sloan Kettering's current (2021-updated) monograph and McGill University's Office for Science and Society (2017) both state plainly that it is not a cancer cure.

NOTES

Harry Hoxsey’s formula combined an internal herbal tonic with an external caustic paste, marketed together from 1924 as a treatment for internal and external cancer that worked by “normalizing” the body’s chemistry rather than by any single, testable pharmacological mechanism. The internal tonic’s individual herbs have documented, mild pharmacological effects (several are laxatives or mild diuretics; none has been shown to treat cancer at the doses used), and the external paste is a genuine escharotic that does destroy tissue on contact, non-selectively, which supplied the treatment’s only directly observable effect and lent its “selectively destroys cancer” claim surface plausibility it did not otherwise earn. Banned from interstate sale in the United States since 1956, the same two-part formula has been sold continuously since 1963 at a clinic in Tijuana, Mexico, making it one of this archive’s few interventions with both a fully disconfirmed historical record and an unbroken present-day market.
