If the “normal sweating” can be restored and maintained, it is the root cause of the disease. In other words, the root cure is up to the patients themselves. After understanding the mechanism of psoriasis, if the “normal sweating” is maintained, it is the root cure. Two weeks ago, a female patient came back to the clinic. She had seen the doctor four times in July and August and her skin lesions disappeared, so she stopped taking the medication. Did she have a “relapse”? To answer this question, we must first answer how to judge the efficacy of psoriasis and how to judge the healing of psoriasis. There are clear criteria for determining the efficacy in the Guangkhan Method treatment system, which is called the “three steps of efficacy”. Why is it called a ladder? It means that there is a hierarchy between the three points of judging the efficacy and they cannot be treated equally. The higher the ladder, the more important it is, and the lower it is, the less important it is. The first step is how is the spirit, diet, sleep, and bowel movements? This reflects the overall health of the patient’s body, referred to as “good spirit”; the second step, whether sweating meets the “four elements of sweating” (“a moment or so, all over the body, ZZ, a slight appearance of sweating “)? This reflects whether the skin is healthy, referred to as “sweating uniformity”; the third step, whether the skin lesions are thinning, becoming scattered? Does the “five good signs of sweating” (“redness, itchiness, newness, smallness and annoyance”) appear? Is the skin lesion thinning? There are also clear criteria for healing in the Guangkhan Method treatment system: on the basis of the first and second points of the “Three Steps of Efficacy”, the lesions disappear or become clearly dispersed, thinning, or close to disappearing, and then enter the period of discontinuation and observation. Within 3 years of discontinuation, all aspects continue to improve, especially the habits that “cure” the disease gradually form and integrate into daily life, while the habits that “cause” the disease slowly move away and are eliminated; the skin lesions are also stable and do not recur. After 3 years of discontinuation of observation and complete self-medication, the patient is considered cured. If the lesions recur within 3 years, the patient should enter the intensive treatment period, then enter the discontinuation period and re-enter the discontinuation observation period for 3 years. After recovery, the daily life is equivalent to the combination and repetition of the “treatment” habits. A relapse is only considered if the skin lesions reappear after healing. In this case, the chances of relapse should be very small.
