Used to get every summer in Oregon--poison oak--one time so bad the Dr thought I had blood poisoning. A Native man told me to eat some of the berries--no way--might work for him. My hubby would go hunting and I would catch as he had rubbed against it so I would see he took his clothes off and put right into the washer. The farmer's would burn their fields and I would catch it from the smoke. Wish I had known about this man's suggestion back then because we don't have any plants like that in Alaska. Just Devil's Club which sticks into your skin and drives you crazy from the pain.
