FAQ

There are real cases where useful ideas were resisted, delayed, or underfunded. H. pylori and ulcers, Semmelweis and handwashing, and artemisinin are strong examples of late recognition. But a real delay is not the same as proof that every rejected cure works.

Define the exact claim, then look for the best human evidence, negative evidence, safety record, and incentives on all sides. A scam usually expands its claims, relies on testimonials, treats all criticism as proof of suppression, and sells certainty before adequate trials exist.

Willow-derived salicylates and artemisinin are useful examples, but both became medicine through isolation, dose control, testing, and standardization. The folk origin is historically important, but the modern evidence is what makes the case strong.

Common reasons include bad fit with the dominant theory, weak financial incentives, difficulty standardizing the intervention, publication bias, stigma, safety concerns, and lack of a sponsor willing to run expensive studies.

The evidence does not support that claim. NCI summarizes laetrile as having little anticancer activity in animal studies, no anticancer activity in human clinical trials, cyanide-like toxicity risks, and no U.S. approval.

Hoxsey therapy was legally and institutionally opposed, so the historical conflict is real. The cancer-treatment claim is a separate question, and major clinical summaries do not find objective evidence that Hoxsey therapy is effective for cancer.

No. Contested means evidence is incomplete or mixed. It is not treatment advice. Safety, interactions, disease severity, and the risk of delaying proven care must be discussed with qualified clinicians.

Because this topic attracts people making serious health decisions. The site is a history and evidence-literacy archive, not a clinical guide, and it should never be used to replace medical care.
