Detox, short for etoxification, in general is the removal of toxic substances from the body. In conventional medicine, detoxification can also be achieved artificially by techniques such as dialysis and (in a very limited number of cases) chelation therapy. There is a firm scientific base in evidence-based medicine for this type of detoxification. Many alternative medicine practitioners promote various other types of detoxification such as "diet detoxification" but there's no evidence that detox diets have any health benefits.
