Your article on skin disease reminded me of Adelle Davis's book Let's Get Well published in 1966, in which she writes about vitamin therapy for many diseases, with substantial medical references.
Cures for skin conditions are mostly the B vitamins and essential fatty acids. For example, 254 patients with psoriasis who were given four to eight tablespoons of lecithin daily had no new eruptions after the first week and even the most severe cases recovered within five months. However, Adelle Davis recommended that only three tablespoons of granular lecithin daily would be required if every nutrient was taken to help the liver produce its own lecithin.
Dietary cures for many other diseases are also described in the book The Food Factor by Barbara Griggs, who writes about the work of many doctors in the field of nutrition. Even schizophrenia can be cured in many cases by diet and avoidance of allergens. CynthiaGale, Chilworth, Surrey....
