PSORIASIS is characterized by patches of red eruptions on the skin that are sometimes covered with dry, silvery scales. These sores usually grow in size without healing. Psoriasis is mainly from lack of enzyme-mutations for eating cooked red fruits and vegetables; those resins congest the lymphatic system. See If I Lack Enzyme-Mutations, What Foods Should I Avoid?, page 174.
Allergies to volatile toxins is also a factor in many cases. See Preservatives and Pesticides, page 196, Edema, page 260, and Overweight, page 296.
Eating plenty of raw fat, fresh raw tomato puree and other raw red and orange foods (like strawberries, cherries, red bell peppers, oranges and carrot juice) along with a balanced raw diet reverses this condition in time. See the book The Recipe For Living Without Disease, Chapter 12.
