Toothpaste works because it's alkaline -- this counteracts bee sting venom, which is acidic.

What it does: Cheaply and effectively soothes the pain of bee stings.

How to do it: Apply toothpaste to stung skin. It takes about 20-30 minutes to have an effect, so leave it on.

Why it helps: The alkaline content in toothpaste alleviates the acidic venom in bee stings.
