TESTING FOR EDIBILITY
If you are foraging for food but are not sure about the edibility of a plant, take a small amount in your mouth, chew it, and hold it there without swallowing for five minutes. If you feel no ill effects - such as stinging, burning or numbness - swallow, and then wait for eight hours. If by that time you have not experienced any cramps, pain, numbing, vomiting, or diarrhea, eat another handful of the plant and wait another eight hours. If there are still no problems, consider the plant safe to eat.
