[QUOTE="Goodgrief, post: 4460742]Here are a few tips I learned from my grand parents who lived close to Native settlements:
Boiled birch bark will cure a fever.
If you get stung by a hornet or wasp, a mud pack will ease the pain.
The height at which a wasps nest sits indicates the snow fall amount for the next winter.
If a loon starts singing on a lake when you are fishing, pack up your gear and go somewhere else. The fish won't bite.

I hadn't heard about birch bark, but willow bark is the origin of aspirin.
