Shock treatment against bites from wasps, snakes and scorpions

Researchers from Seattle successfully use electricity to treat bites of bees, wasps, snakes, ants and scorpions.

It seems that if the treatment is received within 15 minutes after the bite has been inflicted, then the pain stops almost immediately and no swelling will occur. If swelling has already started, then that stops and the pain soon subsides. All the treatments have been performed with 20 to 25 kV, 1 mA DC. In the research the bitten area is electrically grounded as close to the bite as possible.
