Test berries one by one. If they cause a burning sensation in the mouth, spit them out. If they cause no reaction after 15 minutes, eat a small amount and wait 8 hours.
Acorns contain tannins which are bitter and toxic. Soak crushed acorns in running water for 24-48 hours, changing the water frequently, until the water runs clear. Then dry and grind into flour.
Never eat wild mushrooms unless identified by an expert. 90% of fatal poisonings come from misidentification. Stick to known safe species like Chanterelles or Morels (cooked) if you are certain. If in doubt, do not eat.
Before consuming a wild plant, perform a test: touch to skin (wait 15 mins), touch to lips (wait 15 mins), touch to tongue (wait 15 mins), chew without swallowing (wait 8 hours), swallow small amount (wait 8 hours). If no reaction occurs, eat more. Never test mushrooms this way.
