Detoxification is the process of clearing toxins from the body or neutralizing or transforming them, and clearing excess mucus and congestion. Many of these toxins come from our diet, drug use, and environmental exposure, both acute and chronic. Internally, fats, especially oxidized fats and cholesterol, free radicals, and other irritating molecules act as toxins. Functionally, poor digestion, colon sluggishness and dysfunction, reduced liver function, and poor elimination through the kidneys, respiratory tract, and skin all add to increased toxicity. It is recommended that whole body detoxifications be carried out at least four times a year to ensure optimal health of the gut and all the body's glands.
