Through trial and error I figured out how to get the medicinal properties out of the bark and into water. It was through research that I discovered the leaves and berries have even more of the medicinal properties in them than the bark. I began running off batches of the stuff ... called it Wildwood Dean Snake Oil, and began giving it to my friends. Before I take pain medicine for anything, I rub on the Snake Oil. I do not sell this miracle that I call Wildwood DeanSnake Oil ... I give it away. I will ship you a free sample and I am so confident it will help you that I will pay the freight (U.S. only). If it works for you and you want more, I ship 10 ounce bottles (I DON'T SELL THEM EITHER) just send a donation to reimburse me for the cost of gathering and making the stuff and to cover the freight.
