【Indication】 |
Xi Jiao Di Huang Tang is indicated for the heat entering the blood level. The manifestations include: 1. Symptoms of heat harassing the heart spirit, such as fever, delirious speech, a prickly crimson colored tongue, and a thready, rapid pulse. 2. Symptoms of heat burning the blood vessels, such as purpura, spitting of blood, nosebleed, bloody stool, bloody urine, a crimson colored tongue, and a rapid pulse. 3. Symptoms of blood amassment and static heat, manic agitation, desire to rinse the mouth with water but no desire to swallow, and sloppy black stool. |
【Pathogenesis】 |
This is a pattern of intense heat in the blood level. After heat enters the blood level, it harasses the heart spirit, which causes vexation, clouding, and mania. The heat forces the blood to move frenetically, causing bleeding such as spitting of blood, nosebleed, bloody stool, and bloody urine; in addition, the blood that has been spilt out of the vessels can stay in the body and cause an eruption of macules and blood amassment. Heat in the blood level consumes the fluid composition of the blood, which causes the blood to concentrate and form stasis, which produces a dry crimson colored tongue. Heat binds the blood either within or outside of the vessels causing blood amassment and static heat, which manifests as manic agitation and a crimson colored tongue. Heat forces the moistening blood to descend to the intestines, leading to sloppy black stool. The characteristic feature of this pattern is heat harassing the heart spirit, bleeding, blood amassment, and stasis. In this case, the bleeding will not stop until the heat in the blood level is cleared, and the blood stasis will not be dissolved until the blood is invigorated. Therefore, the therapeutic method is to clear heat, resolve toxins, cool the blood, and dissolve stasis. This has been summarized by Ye Tian-shi, a famous expert in warm disease in the Qing Dynasty, as “when heat enters the blood level, there is the risk of blood consumption and bleeding, which should be treated by cooling and invigorating the blood”. |
