far more people die from bee stings than snake bites. this is fact which is why i carry a sawyer extractor. even though i'm not allergic to stings i tried it out once when i got stung by a bee while putting on a pair of pants fresh off of the clothes line. i could see the poison coming out of my skinwhen i removed the extractor i had a small red bump on my leg but no pain or inflamation. worked for me so i keep it around.
i would not know about snake bites and its effectiveness however.
Witchhunter, same experience I've had with the Sawyer Extractor. Twice stung by Yellowjackets, and my wife stung by a large bee of some kind. That Extractor works wonderfully on stings. As you said, I could see the poison being extracted from the stings.
As with you, I don't know what it would do on a snakebite.... but if that was what I had at the time, I'd damned sure give it a try.
