In WWII, the military used a sulfur-based powder to promote blood clotting, especially in traumatic internal injuries. The usefulness of such a product is obvious.
My question is whether there is anything like that available for the average consumer. I have found very little online. One product (Pac-Kit) is out there, but it's offered in very small amounts. It's so small, I imagine it would only be useful for external injuries.
Has this technology been superseded by something even more effective? Has this technology been debunked recently? There are a million first-aid products out there. It's surprising there's not much out there for this.
