A freeze-dried form of bee venom is available in the US as a perscription drug. The venom is re-ydrated such that 1 ml = the equivalent dose of 1 bee sting, and this is injected into the patient. This was what was given to me when I underwent bee sting allergy desensitization. It hurts less than a bee sting. W. G. Miller Gaithersburg, MD
