Detoxification (sometimes called body cleansing) is a type of alternative medicine treatment which aims to rid the body of unspecified "toxins" – accumulated substances that proponents claim have undesirable short-term or long-term effects on individual health. Activities commonly associated with detoxification include dieting, fasting, consuming exclusively or avoiding specific foods (such as fats, carbohydrates, fruits, vegetables, juices, herbs, or water), colon cleansing, chelation therapy, and the removal of dental fillings.
