In 1902, English embryologist John Beard injected pancreatic extracts directly into tumors of cancer patients with therapeutic success. Others tried this method and failed, mainly due to the impurity of the extract preparations, and the therapy fell into disrepute. Later in Germany, Max Wolf, M.D., and Karl Ransberger, Ph.D., utilized enzymes to successfully treat patients with multiple sclerosis, cancer, and viral infections. The two men provided some of the earliest research on enzymes and co-enzymes.

  Hector Solorzano del Rio, M.D., D.Sc., Coordinator of the Program for Studies of Alternative Medicine and Professor of Pharmacology of the University of Guadalajara in Mexico, is one of the many physicians who uses pancreatic enzyme therapy. He has treated a wide variety of diseases-inflammatory conditions such as rheumatic disorders, soft tissue trauma, viral infections, arthritis, multiple sclerosis, cancer, and autoimmune diseases, including AIDS. Dosages are given orally on an empty stomach or by injection, and may be combined with plant enzymes.
