tested out the supposed effect from a medium sized hog female about a year and half ago. I let her chew on my finger for 10 plus minutes, and the effect was a creeping tingle and the finger swelled. No other problems persisted after the swelling went down. I don't recommend anyone doing this though since some people can have serious reactions from bites. The best thing to do is not get bit if at all possible since essentially it is a mildly toxic critter.
