yes,they are effective against the stings of wasps,bees,snakes,etc.
if you put vinegar on wasp stings it will help because wasp stings have alkali in it and vinegar is a weak acid but bee stings are different they are acidic so if you put toothpaste on it it will help (try not to get bee stings mixed up with wasp stings because it will hurt even more if you put toothpaste on wasp stings or vinegar on bee stings)
No. Bee venom is acidic anyway, and wasp venom is chemically neutral, so in neither case will any form of acid help.
Bacitracian ointment can be used for wasp stings. Applying the ointment can help alleviate the pain and minimize swelling surrounding the area.
the wasp sting is full of venom which is alkaline
Toothpaste reduces the pain and swelling of a bee sting (because toothpaste is a base and the bee sting is acidic) Toothpaste doesn't help wasp stings because wasp stings and toothpaste are alkali. (However vinegar works well on wasp stings because vinegar is acidic)
It is a fallacy that you can neutralise wasp venom with vinegar. It came from people believing wasp venom was alkaline: in fact it isn't, it is chemically pretty well neutral. Vinegar is known to have some soothing action for certain skin conditions, but I think with wasp stings a lot of it is a placebo effect.
Yes
the wasp stings the enemies.
The main venom in wasp stings is formic acid.
Onions don't cure bee stings. A bee sting is a cocktail of acids and various proteinic toxins. There's nothing an onion would help with except perhaps distraction.
It f0331ng stings!
