Go outside in your yard and pick a Plantain leaf (it's probably growing as a weed in your yard)Try copy & pasting this:

I actually have better pictures if you don't feel these are clear enough. Anyway, bruise the leaf (crush it up until you can see where it is turning darker from the juice being released) or you can chew on it for a minute (for the same, slightly improved purpose) and then put it onto the swelling as a poultice to help bring the swelling down. Plantain will help with swelling and any itching. Interestingly enough, it will help bring swelling down, but if you get it onto a bug bite or bee sting soon enough, there is a good chance it will never swell or itch in the first place (GREAT for misquito bites that haven't raised yet). All my kids know what this plant looks like and can find it on their own. And incedentally, it's also good diuretic and expectorant, promotes healing, and is effective agains bacterial infections. OH! And if you're trying to quit smoking, something in the tea made from this leaf causes an aversion to nicotine. My husband used it to help him quit smoking seveal years ago.) Of course, I'm sure there are many other methods as well but this is the quick/cheap/easy one that we often use :) I wish I would have known about it when my son got stung near the eye at 18mo!
