<<Disclaimer: Verify this information before applying it to your situation.>> Hi everyone- My husband who is an undiagnosed celiac has had pretty bad DH for the last two years without much success at getting it cleared up. For the last few months he has been on Evening of Primrose along with Vitamins and minerals, St. Johns Wort, Ginko, B-100 and Saw Palmetto all purchased at Trader Joes. His rash has gone away completely. He has trouble staying 100% gluten free so I attribute the success due to some of the supplements. Several Naturpaths have told us that Evening of Primrose helps with Leaking Gut Syndrome. His spirits and energy have also been up which I attribute to the St. John's Wort. For what it's worth it could be useful to others. Good luck! Becky Long Beach, Ca.
