Many products on the market claim to treat psoriasis, including vitamins, enemas, acupuncture, shark cartilage, and emu oil. You can even go to a spa where you relax in a hot pool while little fish eat psoriasis plaques off your body. While a healthy diet and stress management are good for your whole body, no alternative approaches are proven to help with psoriasis, and some may not be safe. Check with your doctor first so you know what’s okay for you. Even some herbal supplements and drugstore treatments can be risky -- more so if you use them with other treatments. So ask before you try.
