Does tea tree oil work to get rid of a poison oak rash? My son stayed with his cousin the other night and came back home with a rash all over his face. He said they were playing in the woods and digging in the dirt and he started itching like crazy when they got back to the house. This morning his face was very red,swollen,and itchy.I put aloe on it and earlier I mixed almond oil and tea tree oil together and put that on him.I can see tiny little bumps coming up and it's migrating down his neck.What to do? Some people are telling me I will have to get him a steroid shot to get rid of it.
