Arizona State University researchers presented evidence at the most recent annual meeting of the American Chemical Society that several types of clay exhibit powerful action against disease-causing bacteria.
After two years of research, the ASU team found that of 30 types of clay tested, three displayed a surprisingly strong effect against such deadly bacteria as E. coli, Salmonella, and even the anti-biotic resistant superbug MRSA. The clay killed all or most of these strains and others in vitro. Special emphasis was put on the volcanic soil known as bentonite
clay.
