It sounds odd and painful but apparently it does work.
It involves an electrical charge passed through the site of the wound. The most common way is to use the charge created by the start of a lawnmower. Remove the wire from the spark plug. Ground one side of the wound to the tip of the plug or body of the engine. The spark plug wire goes on the skin on the other side of the wound. A fast pull on the starter cord does the trick. Something about the low current/high voltage charge that destroys the venom...whether it's the enzymes in it that get zapped or something else, I don't know.
If ever I get bit I intend to try it immediately. Call me nuts but modern medical science has no cure. I would be looking to old time cures if it were me.
That is very interesting, having snuffed a handful of these critters here in FL, I’m going to file this one away. Thanks!
PS - I did a very quick search and see that others have used homemade leads run off of a stun gun to accomplish the same thing. Looks like a nice add to the casual internet research list.
Cheers
