Long story short, I cut my thumb open with a knife and a trainer had to care for it. She had a small plastic tube that she cracked and squeezed on my thumb to stop the bleeding. It was a very thick brown (iodine colored) substance that stung but was VERY effective in stopping the bleeding immediately. Does anybody know what this tube or substance could be? I asked her and she didn't know what the brand was or what it was called. This is driving me crazy, so any and all help would be appreciated.
It is probably similar to a Cederroth blood stopper dressing. It contains crystals that form a gel when in contact with blood, thus producing a gel plug.
