Yea, I personally don't have a lot of hope that stuff like "detoxification" and other alternative medicine stuff will actually heal EC. It might in some cases contribute to a somewhat healthier body, but it won't heal the condition (at least the one I have, it seems like people like shea78 and longterm might have something totally different).
A healthy body in general, which one should be able to come close to by having a healthy diet, "healthy mind" and doing enough excercise, will have the best chance to be able to fight this condition. Some miracle wheat grass juice alone will not do the trick on its own. So you might want to add wheat grass juice to your diet because it is supposed to have good effects on your health, but don't expect it to heal your EC.
