@Tadano @scalar @BowsacNoodle @JedKron1248 @vic The first thing is that psoriasis is not a skin problem. It could be a gut problem, it could be heavy metal poisoning, it could be other toxins from the environment, it could be a result of a parasitic or fungal or bacterial infection or some combination of the above and other factors.

Elimination diet where you cut out grains, sugar, alcohol, nightshade foods, non-fermented soy, and dairy for anywhere from 3-6 months have good anecdotal reviews. I would add vitamin D supplements and fermented foods to the elimination diet or at least probiotics to try to rebuild the gut flora which in most autoimmune patients is compromised. For a lot of people, this solves the psoriasis and often other autoimmune issues like IBS or arthritis.

If that helps but doesn't fix the visible symptoms of psoriasis, then there are other issues like heavy metals or foreign agents (bacteria/fungi/parasites) and you would have to remove those.
