I think you should do a series of liver flushes. It won't cure your problem completely on its own but it will help alot. You need to cut out all known food allergens which are the worst. For me, one egg will give me a Psoriasis flare.. so allergens are definitely the issue. Take vitamins and minerals that are known to help the body cope with allergenic response, for example vitamin b5. Cutting out all allergens and taking b5 might help. Also taking a supplement for your liver will help, Milk Thistle 6000 per day at least.
