sting therapy is popular for things like arthritis and ms. info can be found on the www.
i would not actually perform the therapy for another. if they were to have a reaction, it could be your hide that gets torn. neither would i advertise my bees for this purpose.....however......there is a local bee keeper who will jar up a few bees, no questions asked, and sell them to you for a buck.
if someone were to come up to me and ask for a few bees in a jar, i'd probably go along with that.
