Cancell, also called Protocel, Sheridan's Formula, Jim's Juice, Crocinic Acid, JS–114, JS–101, 126–F, and Entelev, is a formula that has been promoted as a treatment for a wide range of diseases, including cancer. Cancell is available in tablet and liquid form. Originally called Entelev, the formula was developed by biochemist James V. Sheridan. Sheridan sought to target the primarily anaerobic cell metabolism of cancer cells (following the theories of Otto Warburg), claiming to lower cell potential leading to the destruction of cancer cells. The Cancell formula was tested by the National Cancer Institute and found to be ineffective against cancer,[1] though Cancell continues to be marketed as a dietary supplement in the US.
