The sting caused by 
stinging nettles aka Ertica Dioca is from the formic acid, which also causes the sting of bee stings.
The cure for the sting is on the inside of the boiled nettle leaf, as boiling this herb destroys the formic acid & releases its antihistimine properties!
Therefore, if you are allergic to bees, have someone else pick & boil nettles for you, & then drink the boiled decoction of nettles & you will actually raise your immunity against bee stings.
Boiled nettles are very tasty, have several very healthful properties, including being an effective anthistimine to overcome allergies.
Nettle leaves: boil in water & drank liberally as highly-nutritious antihistimine
Local, Raw, Unfiltered Wildflower Honey OR Bee Pollen: as homeopathic remedy internally sparingly
