"Detoxify. Many times, allergic symptoms will improve as toxins are removed from the body. The only methods I most recommend are the use of a dry, low-temperature, preferably near infrared light sauna, coffee enemas, colonic irrigation, or other means of sweating such as steam baths, perhaps. Be sure to avoid ionic foot baths such as the BEFE, Q2, Bio-cleanse and others, as these are not safe. Nor do I recommend clay baths, although they will detoxify the body to some degree."
