i've been using it for YEARS

on my face (as a NATURAL clay mask that is). it is also used as a natural insect repellent on crops. it was also THE active ingredient in kaopectate. seems WAYYYYYYYYY back in the day, south american natives saw parrots eating it (how they assumed the parrots ate it to sooth indigestion, i'll never know) and copied the birds

what a wonderful invention, gauze that helps stop blood loss. AND the company that invented it is in MY state

Nanoparticles Help Gauze Stop Gushing Wounds
By Aaron Rowe
Medical gauze hasn't changed much since World War I: Medics can only stuff it into a gushing wound and pray.
Now chemists have infused cotton gauze with nanoparticles, giving it a vastly improved ability to halt blood loss -- even in tight spots like the neck or groin where it's hard to apply pressure. The new material could help save lives on the battlefield and in civilian situations, where trauma victims often bleed to death before they can be transported to a hospital or other medical facility.
"We are currently testing bandages because hemorrhage is a leading cause of death in military trauma patients," says Richard McCarron, head of trauma and resuscitative medicine at the Naval Medical Research Center in Silver Spring, Md. "The recent tests with Combat Gauze indicate that it decreased blood loss and improved survival." The lifesaving fabric McCarron refers to is made by Z-Medica, a medical products company based in Connecticut. According to Z-Medica CEO Ray Huey, the new product has already saved two lives. ......

..........................Ironically, the solution to the heating problem lay in replacing QuikClot with a material that has been used in medical tests for more than 50 years. The key ingredient in the new gauze is kaolin clay, which is often used to make pottery and happens to be rich in aluminosilicate nanoparticles -- which trigger blood clotting. ..............
