【Indication】 |
Da Xian Xiong Tang is indicated for thoracic accumulation caused by the binding of water and heat. The symptoms are pain that refuses pressure below heart, hardness in the diseased location, or there is a full, hard, and painful region below the heart and above the lesser abdomen and touching is not tolerated. Other accompanying symptoms are shortness of breath, vexation, constipation, and mild tidal fever in the afternoon. The tongue is red with a yellow greasy or watery coating, and the pulse is deep and tight or deep, slow, and powerful. |
【Pathogenesis】 |
This pattern is an excessive pattern caused by the binding of pathogenic heat with retained fluids. These two pathogens stagnate and form a hard, painful mass that refuses pressure below heart. The hard and painful region may even extend to a wider area from below the heart to above the lesser abdomen, and no touching is tolerated. When water and heat bind in the stomach and intestines, it leads to constipation, mild tidal fever in the afternoon, or short breath and vexation. The bind also prevents the body fluids from spreading upward, so there is dry mouth and thirst. The red tongue with a yellow greasy coating and deep tight powerful pulses are signs of the water and heat bind in the interior. Draining heat and expelling water should treat this type of syndrome. |
【Clarification】 |
What is the purpose for da huang being decocted ahead of the other ingredients? According to the indications of this formula, the location of this disease is as high as in the chest. Da huang is decocted ahead of others to reduce its purgative power as is instructed by the therapeutic principle, “treat disease located high up in the body with mild”. |
