105. Exogenous illness, after thirteen days, the pathogenic factor has advanced into endo-yang causing delirium, this is solid heat congestion in stomach system, should be purged using cool purging soup. If urine is normal and smooth, the stool should be hardened, but instead the patient suffering from loose motion, the pulse is strong, we can conclude this is due to wrong purging using warm laxative pills by the doctor. If it is not due to wrong treatment and the illness is advancing into endo-yin and causing diarrhea, the pulse should be weak, four limbs are cold. If the pulse is strong, this is an indication of solid heat congestion, before that the doctor may wrongly purge using warm purging pill, the stool is purged but the heat is not removed, should apply the treatment using Tiaowei Chengqi Tang.
Note: During Han dynasty, around AD 200, some doctor like to purge the stool using the pill made by Badou, a poisonous bean that is very heaty and cause strong purging. For heat congestion, there is energy heat congestion with little or no stool, no purging is allowed, can be treated with Baihu Tang. Only when the stool is formed, which is materialistic and known as solid heat congestion, then cold purging soup is used. Solid heat congestion always cause high fever after the noon.
