Hoxsey’s central promotional claim, made from his first Taylorville clinic in 1924 onward and carried through decades of advertising and public healing sessions: that his family formula cured cancer outright, sparing patients the surgery, radiation, and x-ray treatments of conventional oncology. The claim rested on patient testimonials and case reports selected by the clinic itself, not on controlled clinical evidence. The National Cancer Institute’s review of Hoxsey’s submitted case reports found none met its evaluation criteria, and the federal government’s Food, Drug and Cosmetic Act enforcement action found that specific individuals Hoxsey’s own promotional booklet named as cured had not in fact been cured.
