The efficacy claim of Fasting for the Cure of Disease (1908): that supervised fasting cures chronic and organic conditions, including some that orthodox medicine could not. This is a hard-endpoint claim, the cure of actual disease, and it is refuted. There was no controlled demonstration, and the documented outcome was the opposite of cure: at least fourteen patients in Washington died of starvation under Hazzard’s direct care between 1907 and 1913, and in 1912 she was convicted of manslaughter in the death of one of them (Washington State Archives).
