M. from USA just wrote that she was asked by her friend if she knows any essential oil that can help in the case of being bitten by a black widow spider.

Soon after sending her recommendation her friend wrote back:

Thank you! The only oil I have is lemon so I put some of that on and it is like magic. The whole thing vanished instantly!”

It makes sense, especially if instantly applied, that because of the Lemon* astringent (contracting) and cooling properties, it also may help both to reduce the pain, and to diminish the scar and the spread of the bite toxicity.
