Boil the bark of a blackberry root and strain. Use this juice to cook rice and serve with a lot of cinnamon and nutmeg. This will cure diarrhea.

For nausea and vomiting, mix a cup of strong slippery elm bark tea with 2 tablespoons of honey, 1/4 teaspoon cinnamon and 1/4 teaspoon ginger. Take in small sips until you feel better.
