i got my first bee sting a few hours ago. i had heard about using plantain (Platago major)... pick a leaf, chew it up to release it's juices, and apply it to the sting. almost immediately, the pain subsided - the stinging stopped - the swelling went down. you can keep it in place with a band-aid.
plantain is known to have amazing drawing power. it pulls out poison and draws out infection. it can also be used for cuts or scapes since it has a lot of value in calming skin conditions.
maybe you have seen it growing around your yard or neighborhood... most people think of it as a 'weed' - but it is not. i am happy to have this 'weed' growing in my yard.
