The Story of Richardson Nutritional Center

Dr. John A Richardson, M.D. and Patricia Irving Griffin, R.N.

Where It Started

In the 1950s and 1960s, word began to spread about the power of Laetrile. Although it was not approved for treatment by the FDA, doctors like John A. Richardson M.D. began using it at his clinic in the San Francisco area. His results with Laetrile are documented in the book, Laetrile Case Histories; The Richardson Cancer Clinic Experience by John A. Richardson, MD, and Patricia Irving Griffin, RN/BS. Originally written in 1977, the book was updated in 2005 with follow ups on the patients they treated
