Hulda Clark? That says it all!

Hulda Clark has been criticized because her claims lack scientific validity and consist of anecdotal evidence. Joseph Pizzorno, a prominent naturopathic physician, evaluated Clark's claims and found that her books mixed patients with conventionally diagnosed cancer with those whose cancer diagnosis was based solely on her use of the "Syncrometer". The patients with medically diagnosed cancer did not respond to Clark's treatment, while those she had diagnosed using the "Syncrometer" were "cured". Pizzorno concluded that Clark's treatments were ineffective and that treatments based on Clark's recommendations "pose a substantive public health danger".^[14]

The Swiss Study Group for Complementary and Alternative Methods in Cancer (SCAC) issued a strong warning to cancer patients considering Clark's methods:^[15]

In September 1999, Clark was found and arrested in San Diego, California, based on a fugitive warrant from Indiana. She was returned to Indiana to stand trial, where she was charged with practicing medicine without a license. The charge was later dismissed for failure of speedy trial. The judge's verdict did not address the merits of the charges but only the issue of whether the delay had compromised Clark's ability to mount a defense and her right to a speedy trial.^[2]

In February 2001, Mexican authorities inspected Clark's Century Nutrition clinic and ordered it shut down, as the clinic had never registered and was operating without a license. In June 2001, the Mexican authorities announced that the clinic would be permitted to reopen, but was prohibited from offering "alternative" treatments. The clinic was also fined 160,000 pesos (about $18,000), and Clark was barred from working in Mexico, even as a consultant; however, the San Diego Union-Tribune reported in 2003 that there was evidence that Clark continued to work at the clinic.^[11]
