Wow, good info, Recondoc!!
I once had a badly bleeding (but not really serious) wound on my hand. An old Vietnam medic grabbed my hand and dumped a bunch of SUGAR onto the wound, which quickly absorbed blood, and hardened into a crust! It wouldn't have done for a situation where I needed to keep moving, but in a pinch, it was nice to stop leaking!
I recently overheard a lecture on combat meds from an Iraqi contractor (former military medic), and he was all about pressure, even including tourniquets. He said that the fear of tourniquets that's drummed into us from first aid classes is overdone, and they're very reliable lifesavers.
I look forward to absorbing Recondoc's web info... Thanks again.
