There is no direct mention of "psoriasis" in Ellen White's books. However, there are several references to skin diseases, scaly skin, and the importance of skin health. Most of these references discuss leprosy, general skin conditions, or the effects of unhealthy habits and cosmetics on the skin. Here are some relevant points from the books: - Ellen White often refers to "skin diseases" in general, sometimes as a result of improper health habits or the use of harmful substances (HL 190.6, HL 189.2). - She describes the healing of leprosy, noting the disappearance of a "rough, scaly surface" and the restoration of healthy skin (DA 263.4, MH 69.4, 2SP 229.2). - She emphasizes the importance of proper air, bathing, and exercise for maintaining healthy skin (HL 226.3, 1T 701.1). - There are warnings against cosmetics that poison the skin and blood (HL 189.2). - No specific advice or commentary is given on psoriasis as a distinct medical condition. If you are looking for spiritual or health principles related to skin health, Ellen White's writings encourage natural remedies, cleanliness, fresh air, and a healthy lifestyle. For information specifically about psoriasis, there isn't adequate information in the available sources to answer this question directly. References: - White, E. G. (1890).
