My husband has problems with his skin on his back. It becomes very dry and itchy in patches and we can't get to the root of what the trigger is for it.

This happens periodically and we've tried everything on it to soothe it. No matter what we use, it keeps coming back in different areas. This has been ongoing for about five years now.

Any ideas on how we could treat this from the inside out? I'm thinking that there have to be some foods or supplements we could try . I'd like to see if we can heal this from the inside instead of using topical treatments. Thanks!
