Herbalism... one of my favorite topics. Here's a few things from my neck of the woods!

I agree with someone else who mentioned using tobacco as a poultice for bee stings.

Catnip, spearmint, or peppermint tea for cramps.

Ginger for upset stomach.

Lavender essential oil on the temples for mild headaches.

Tea tree oil- aside from medical uses, dilute in water to make a disinfectant cleaning spray (add orange or lemon oils to boost cleaning power and make it smell nice)

tobacco- steep and use in spray bottle to keep some pests away(not to be used around food, of course)

and my grandmother always drank a spoon of vinegar a day, she claimed it kept her healthy (i haven't the stomach for that, personally).
