If you are stung by a bee rub over with a half onion on the sting am in the onion!
Put sugar directly to a bee sting. The easiest way that a sugar cube, but a teaspoon of sugar with a drop of water also works fine. Optionally repeating after few hours.
Bee sting can be quite painful but the pain disappears when it fills up with Eau de Colonge 4711 my kids had always benefit.
Have you just been stung by a bee or wasp? Keep the flame of a match or lighter near the place where you are stung, so it just does a little pain (no burns though!). The heat from the flame causes the poison breaks down and you have no more trouble!
