I’ve already bought pine resin oil 20% extract 3 times from you, guys. The result is excellent – I had gastritis, but the treatment with prescribed medicine did not help me, and I started drinking pine sap on the advice of a friend. Gradually stomach ache disappeared, everything became fine with the digestive tract. Now I am ordering the pine resin 20% extract for my annual Siberian cleanse. It is a natural preventative remedy. I do recommend.
