I was picking blackberries in Oregon and a few days later I started getting a rash on my wrist. I realized it was poison oak. I did some searches on the net and found that peppermint and franckinsense oil helped others... I used them... It helped me too... and it took the itch out and made it feel cool. It dried up in about 3 days.
