About Ernst T. Krebs
Ernst Theodore Krebs Jr. was an American promoter of various substances as alternative cures for cancer, including pangamic acid and amygdalin. He also co-patented the semi-synthetic chemical compound closely related to amygdalin called laetrile, which was also promoted as a cancer preventative and cure. His medical claims about these compounds are not supported by scientific evidence and are widely considered quackery.
