In his youth, Dr. Christopher began his own study on natural healing when he saw its positive results in healing his mother of dropsy. His enthusiasm increased when he cured himself of cancer using natural methods. Dr. Christopher, after his experience as a supervisor of a medical dispensary during World War II, decided to become an herbal practitioner. In 1946, he graduated with a Master of Herbology under Dr. H. Knowles at the Dominion Herbal College in Vancouver, British Columbia. Two years later he received his Naturopathic Doctor degree from the Institute of Drugless Therapy in Tama, Iowa. He received an Herbal Pharmacist degree under the renowned Dr. Edward Shook. Hailed as America's foremost herbalist, Dr. Christopher developed a program to pass on his methodology and founded the School of Natural Healing in 1953. His published works include Herbal Home Health Care, Every Woman's Herbal, and his most renowned work, School of Natural Healing. Prior to his death in 1983, Dr. Christopher received the Agnes Arber Distinguished Service Award for his long-suffering devotion to the cause of herbal practice and his contribution to public health.
