94. Exo-yang disease, even not yet recovered, if the top and bottom pulse is quiet and normal, then the body will tremble and then sweat and the illness will be cured by itself. If top pulse is weak and soft, can apply induction of sweat. If the bottom pulse is weak and soft and there are sign of constipation, use Tiaowei Chengqi tang.
Note: When a patient is suffering from exo-yang illness, after he is wrongly treated with purging, we should check the pulse, if the pulse become quiet and normal, we do not need to treat the patient and interfere with his body system, best is to let him recover by himself. Even if the patient is not wrongly treated before, if the pulse is good and normal, then it is the sign indicates the patient will get well and we need not intervene. Before getting well the patient in this case will tremble and then sweat. This is a good action of the body to induce sweat by itself and we should not worry. However, if the pulse is weak and soft and indicating the problem is not going to get well soon, then for exo-yang we apply Guizhi tang to induce the sweat. If bottom pulse indicate there is some problem, and the patient show signs of stomach system dehydration and stool congestion, like thirst and constipation, then we can purge the stool by regulating the stomach system. Tiaowei mean we regulate (tiao) the stomach (wei). Tiaowei is a famous formula to regulate the stomach and purge the stool. Pure purging without regulate the stomach like using the purging salt will weaken the stomach and lead to complication.
