During David C. Cadden's many years in private practice he encountered numerous cases of psoriasis. Unfortunately, hypnosis is often used as the last resort, when the sufferer has already tried the usual drugs, ointments and potions without success. Although there is in almost every case an emotional or psychological cause for the problem,  David found it quite possible, to encourage the body through the power of the sub-conscious mind to improve and in most cases clear the condition completely, regardless of the cause.
