When I first got psoriasis and psoriatic arthritis, the patches started covering my body. I started taking two tablespoons a day of flaxseed oil. it’s been nothing short of a miracle for me. I’m 90% clear now ! It’s about $20 a bottle. Might not work for you, but well worth the investment. You should see results in a month or less. Folic acid is worth a try too. Good luck!
