I wonder if they could somehow control the venom to only spread so much to help coagulate blood from a wound. Like if someone had an accident and lost a few fingers EMT's could inject them with something to help coagulate the blood FAST, like in the video.
I realize that venom by itself would be a bad idea to do this with but i wonder if theres like a specific protein or something that could be isolated by scientists to use.
Im probably being rediculous here but i think itd be cooool!
