Charles E. Chagnon was a physician and registered pharmacist located at 65 Washington Street in Arctic, RI circa 1900 - 1936. He had put out a Chagnon's Headache Cure which he claimed had been on the market for 24 years having been previously manufactured by his father, a prominent Fall River, Massachusetts physician.

In 1907, Dr. Chagnon claimed to have cured over 2,000,000 people, saying that his product was a remedy which was the ultimate non narcotic cure for headaches, effective without containing heart depressing drugs, and which was imitated by many others but never becoming equal in respect. He also claimed relief in five minutes from headache and also cured neuralgias, periodical pains, colds, grippe, sleeplessness, and all fever conditions. The cure sold for twenty-five cents a box which contained ten doses per box, and was available by mail order to anywhere in the world upon request.
