Scientists aren't sure how some clays kill bacteria. Metals in the clay may be the active ingredients. Or the highly charged molecular surfaces of the clay minerals may tear up bacterial cells Salmonella typhimurium, shown in red, is one of the bacteria that was killed by a type of clay five years ago when the late French humanitarian worker Line Brunet de Courssou reported that a French clay called Agricur was effective against the flesh-eating disease Buruli ulcer in Africa's Ivory Coast.
"They would mix clay with water and make a paste and put it on the horrible wounds When daily applications of the clay caused too much pain another French clay was used It was the second clay that killed [the bacteria], although the clays are mineralogically identical, |
They're not sure why it works, and are trying to pin down why. There can be two very similar clays, with only one having the healing process, but they have a few theories they can check, such as slight variations in mineral content, or structure. It has been used successfully in treating flesh eating disease in Ivory coast.
