One of the most interesting things I recommend is a spider web to stop bleeding from small annoying cuts or scratches, such as we might get from paper or a rose. And I mean a clean fresh one, not some dusty relic from the attic!
I will also testify to peroxide as a valuable element of a conscientiously applied program of oral hygiene and regular professional care. It was recommended to me by a dentist years ago, in the difficult days following a sad but necessary end of a long-term relationship with an insurgent wisdom tooth, and I just sort of kept it up.
Killing all those germs seemed like a good idea, and after a while, my teeth did appear noticeably whiter, and to this day people say nice things to me about them.
I can also recommend the ancient wisdom of using dirt as a cure for nausea - just plain old dirt from the yard. Put it in a bowl, paper plate, even your hand, hold it under your nose, breathe deep and smell it. This will somehow settle the spirit that is causing the nausea, and make it stop.
And if a baby has hiccups, make a red mark on its forehead, and they will stop. Be sure to use something non-toxic, like a kid-safe art product, or lipstick. I cannot explain this, it's another one of those thousands of years things.
My latest and oddest recommendation of an actual product, I guess, would be Krylon leafing pens for gilding page edges...
