Stevie's auto immune disease

Stevie has auto immune disease which affects his skin.  It attacks and rejects the bodys own tissue as foreign.  He's been on steroids for a while which is helping but he still gets attacks which is stressing for him.  We haven't quite got the timing right yet with the injections but we're working on it.  It would be great if I could find something along the homeopathy line which would help. The less steroids the better.  Trying a couple of things at the moment, maritime pine bark and wheatgerm oil, both of which have been recommended.  I'm giving him a quarter of a tablet once a day of the maritime pine bark and massaging the wheatgerm oil onto the affected skin.  Just started yesterday so it'll probably be a while before we see any signs of improvement if there is any. I really hope there is.

Stevie is a dote and was fine until he was about 8/9 months old and then this suddenly developed around summertime last year. There's no doubt it affects him and he seems a bit down when having an attack so fingers and toes crossed this works and he can come off the steroids.
