I was given a bottle of buttermilk. I decided to put it in the tub this morning. After my bath I put on some lotion. Right now I'm noticing all the psoriasis flaking. I'm going to buy some powered milk to try as I don't have anymore buttermilk. I've been struggling with severe psoriasis for years. If I had known it was this easy for it to flake off I'd tried it years ago.
