systemic mastocytosis
"My daughter has been using this for her  Mast Cell Activation Disorder (MCAD) since 2010, and it is a miracle!  She gained 30 pounds in 6 months because she was finally able to absorb her food, thanks to the Gastrocrom.   She is on a lot of different medications, but Gastrocrom was the one that finally tied everything together and started her on stable path."
