Hey, this is the Dr. Schulze Forum , so do what he says to do for psoriasis. Jojoba & Tea Tree Oil, Deep Tissue Oil, and a 5 day cleanse. I make up my own Dr. Schulze formulas following his instructions, and Iíve found his Deep Tissue Oil is nothing short of a miracle. Itís really wonderful stuff. But you donít have to waste your time making all of these things up. You can order all of these formulas already made up and ready to use, directly from Dr. Schulze at the American Botanical Pharmacy. I donít know how fast it will work for your brother, each person is different. But it really does work.
