Actually, I am planning on using scorpion venom as I do bee venom - in combination with acupuncture. Put some on the skin and needle through it, taking some into the skin. People also inject bee venom intradermally to stimulate similar beneficial responses that bee stings do (formic acid is the active compound in bee, wasp and ant venom). There is a lot of tribal use of venoms and poisons as medicine - the use of Kambo, a frog poison from the Amazon; smoking or ingesting the poison of the Bufo toad; the bullet ant (tucandeira) rituals of the Satere-Mawe and Marubo tribes in the Amazon; the use of bee stings in China, India and in Native American tribes.
"In terms of the health benefits of the Tucandeira Ant Ritual, it is worth highlighting the potential biological effects of the ant stings. By injecting formic acid into the organism, these stings contribute to the individual's endogenous defense, increasing immunity to diseases. This question has been examined by Nunes Pereira (2003, p.68): "The stings of the tocandiras are not applied only in the initiation ordeals; the Maué believe in the curing power of formic acid, particular to the stings, since whether in cases of malaria, colds and flus or any other infirmity, they apply the stings to the part of the body where the illness is thought to be located." Indeed in the Sateré-Mawé community of Y'Apyrehyt, without any connection to the initiation rite, the sting of one or two tucandeira ants is used to cure sore joints and relieve menstrual cramps. And since it is impossible to specify where and when this ritual originated, it would be inappropriate to separate the social component from the practice's medical usefulness, both united by the historically accumulated knowledge of the people in question.
An important photographic document exists - made by Harld Schultz, of the Museu Paulista - of a Krahô woman rubbing nettles, rich in formic acid, on her daughter who had been stung by a scorpion (Figure 13). The author recorded: "The strange therapy sent the girl to sleep. On awakening, she was entirely cured" (Schultz, n.d.). In the same work the author emphasizes the practice of bloodletting (Figure 14), making the following comment: "For the Indians, bloodletting is a stimulant for the senses and a factor in resistance to pain. The wounds produced with shark teeth are rubbed with juice from bunches of pepper tree leaves, a process that seems to help close the wounds by inducing contraction."
