It was two years ago to this date, my father had poison oak and couldn't get rid of it. Hydrocortizone, buttermilk (suggested by a concerned source) Benadryl cream and allergy medication didn't help him. Both my father and I are very immune to poison ivy, but when it comes to Poison oak, it's just too bad. Poison oak is the worst rash you can get possible. If you go out into the wild, hike and hunt. You need to know what this plant is to avoid high medical costs and unnecessary purchases.

Always wear long pants if you decide to go out in the wild. This invasive species can be deadly if you have complications that are high risk. It just takes one touch with this plant and you are covered from head to toe with rashes.
According to a PoisonIvy.aesir.com , it takes just one gram of poison oak to get a rash from head to toe. It isn't discriminate to anyone. It loves everyone, but the paperazzi isn't wanting to follow it.

Poison Oak comes in a three leaf cluster that grows low to the ground. It's easy to brush up against it and get a rash. It you scratch your rashes, you can spread the poison throughout the body. Please be careful this summer in planning your lake ventures, hiking amongst the great wild. Enjoy yourself and be careful!
