Was at the Health Food Store picking up more Barley Grass for my boyfriend's Crohn's disease when I overheard a man looking for Pau D' Arco tea for his Crohn's. Apparently after many years of suffering from this disease, he only had 18" of his intestine left and after that was going to have to wear a bag. But he discovered this tea and has been drinking it every day and hasn't had any problems since. My boyfriend doesn't drink tea but I found capsules for him and he takes two a day along with the Green Barley Grass (two a day 500 mg each) and he swears this changed his life. He hasn't been sick since December of '13. We do not run out of the Pau D' Arco or Green Barley Grass anymore.
