Essiac Products

Essiac Canada International is a healthcare company focused on the production and global distribution of the Essiac herbal formula. Originally developed by Canadian nurse Rene Caisse in the 1920s, the formula is a proprietary blend of four main herbs: burdock root, sheep sorrel, slippery elm, and Indian rhubarb. The company acquired the rights to the original formula from the Resperin Corporation, which had received it directly from Caisse. Currently, Essiac is marketed as a dietary supplement intended for immune support and detoxification, though it remains a prominent name in alternative oncology. The company operates primarily through its headquarters in Canada and distribution networks in the United States.
