My sister had psoriasis so bad that she could barely walk...it was especially severe on her feet. To look at her, you would never know since she was able to cover the areas that were affected.
For at least 10 years I suggested she take fish oils, flaxseed, or primrose oil. But she refused....she didn't believe in supplements.
I got a call from her about a month ago. She's been taken fish oil supplements, and the psoriasis is completely gone!
I am so happy for your sister. It's so difficult to see people destroy themselves with drugs when there are far safer and more effective alternatives.
