Revici's Guided Chemotherapy is an ineffective cancer treatment devised by Emanuel Revici (1896–1997).
Revici's early work on experimental chemical-based treatments for cancer between 1920–1941 attracted a degree of support. However his work increasingly found disfavor with the scientific and medical communities and his license was revoked in 1993.
Revici's Guided Chemotherapy is based on the idea that all illness is caused by an "imbalance" of metabolism. The treatment is giving a mixture of chemical substances (usually including lipid alcohol and various metals) by mouth or injection. The American Cancer Society notes that this "chemotherapy" is entirely different from modern conventional chemotherapy, and states: "Available scientific evidence does not support claims that Revici's guided chemotherapy is effective in treating cancer or any other disease. It may also cause potentially serious side effects."
