Put a bit of bentonite or Montmorillonite clay on it! Clay is very helpful for itching and a number of other skin issues such as acne. It particularly helps heal venomous stings and bites, like from bees, wasps and spiders. The clay helps draw the venom out of the skin, which will help relieve the pain and let the sting heal more quickly.
Use virgin, untreated clay, such as this one. Green clay (often called montmorillonite or bentonite clay) is the most powerful type. (For more information on the amazing healing power of clay, I highly recommend reading The Clay Cure by Ran Knishinsky).
