My youngest daughter, Leah, was stung by a wasp last week. It was pretty painful and swollen for a couple of days. I made the following concoction that seemed to bring down the swelling and lessen her pain:
1/4 cup baking soda and then stir in
apple cider vinegar--enough to make a thick paste
Sit on a towel because it can be a bit messy and generously put the soda paste on the sting. Leave on for at least 30 minutes. Wash off and reapply daily.
She's doing much better now!
