The version we use is common in North America - sporadically found and mined from the province of Alberta to the northern plains of Texas. Dr. Bernard Jensen, and other naturopaths, have recommended Bentonite for years as yet another vermifuge (parasite cleanser) and general detoxifier.
Its use among naturopaths is primarily internal. Unless otherwise recommended by your health care practitioner, you should stick to the one teaspoon/day protocol.
Feldspar Pre-Mix For external use only - this clay variety is good for facials and assists in drawing toxins out of the skin. Variations of this clay (and "Red Cedar") were used extensively by native American indians, through their "medicine men" to treat a wide variety of dermatological problems.
Kaolin (USP) Pre-Mix For internal use: this is the active clay used in Kaopectate™ and other anti-diarrhea formulas.
The version we use has been processed to meet USP (United States Pharmacopaeia) standards of purity. There is nothing new about the application of clay to treat diarrhea and dysentery -- the British used this clay as a standard issue, going back to World War I, to provide soldiers in the field with relief from pathogenic bacteria, parasites, and protozoa that would infect their troops in foreign areas of military engagement.
Red Cedar Pre-Mix For external use: this montmorillonite clay is good for use on the skin, over the site of sore muscles, sprains, and aches. Even among Alpha Omega's own staff, it has miraculously assisted with a variety of "deep tissue" issues. Although its mechanisms of action are not fully understood, we have never seen a toxicological or other adverse reaction related to its use.
