The common plantain, a weed found in many yards, has powerful "drawing" properties. You can use the fresh or dried herb, available at herb stores or online (try mountainroseherbs.com). To use, mix the chopped herb with a small amount of water and apply to the bite or sting. Within minutes the area will become warm as toxins are drawn from the skin. Add more plantain as needed until the pain and swelling have subsided.
