I wild forage medicinal mushrooms and herbs, and make oils / tinctures from them.

I can't recommend mullein enough for chest colds / coughs. Tea made from the dried leaves actually works like a cough syrup. It's my goto now.

Little known fact is mullein flowers contain an aquatic tranquilizer, which means that in a survival situation, you can sprinkle them into a pool and all the fish will become unconscious and float to the surface.

I'm building my own pharmacy in case the one down the road goes away.

I have various tinctures to treat pain, emotional issues, blunt forced trauma, superficial wounds, and skin infections.
