Exo-yang illness, after four or five days, body is feverish, aversion to wind, stiff neck, area below the ribs is full and congested, four limbs is warm and the throat is thirsty. This is due to exo-yang, intero-yang and endo-yang are ill simultaneously. Treat with Xiao Chaihu tang.
Note: 1). Aversion to wind and stiff neck is exo-yang syndrome, area below the rib is full and congested, that is intero-yang illness, warm limbs and thirst is internal heat which is endo-yang. Comparing the last article, the limbs are warm but could not drink water, that indicate stomach waste water congestion and Xiao Chaihu tang may not be suitable. In this article, the limbs is warm and the patient can drink water, we can apply Xiao Chaihu tang plus Shigao to clear the heat in endo-yang. 2). When ever intero-yang symptom is there, induction of sweat and purging of stool are prohibited. So the application of Xiao Chaihu tang is the main application.
