In the 1950s, Dr. Arthur F. Coca invented an elaborate method to diagnose a new kind of "allergy" by testing the pulse rate. He thought "allergies" were the underlying cause of most disease. His method has never been tested, but there is every reason to think it is bogus.
The idea that antidepressants are no more effective than placebo has been put to rest. They clearly work when used appropriately, although the effect size is not as large as the published studies have suggested.
Practicing after he lost his license, chiropractor Nicholas LeRoy used escharotics to treat a woman's cervical dysplasia. As result, she lost her uterus.
