Note: The Xie Xin Tang (Drain the Epigastrium Decoctions) series are all used to treat conditions where the exterior syndrome has resolved but the interior qi is not harmonized after wind-stroke and subsequent sweating or purging therapies. Among them, Shengjiang Xie Xin Tang (Fresh Ginger Drain the Epigastrium Decoction), Gancao Xie Xin Tang (Licorice Drain the Epigastrium Decoction), and Banxia Xie Xin Tang (Pinellia Drain the Epigastrium Decoction) are formulas for treating pi (epigastric fullness/oppression) caused by the accumulation of phlegm-dampness. In these formulas, Banxia (Pinellia Tuber) and Shengjiang (Fresh Ginger Rhizome) are used to clear phlegm-fluids, Huangqin (Scutellaria Root) and Huanglian (Coptis Rhizome) to clear damp-heat, Renshen (Codonopsis Root or Ginseng Radix) and Gancao (Licorice Root) to support stomach qi, and Ganjiang (Dried Ginger Rhizome) charred to leach out water-dampness. If only bitter-cold herbs are used to clear heat, it will lead to rejection and non-absorption; thus, acrid-hot herbs are necessary as guides. Therefore, Ganjiang (Dried Ginger Rhizome) and Banxia (Pinellia Tuber) are essential. If the pi is extremely hard and full, temporarily remove Renshen (Codonopsis Root or Ginseng Radix); if qi stagnation rises upward, do not use Shengjiang (Fresh Ginger Rhizome); if the pi is present but not hard, still use Renshen (Codonopsis Root or Ginseng Radix). This represents modifications of one formula yielding three different treatments. As for the other two Xie Xin Tangs involving Dahuang (Rhubarb Root) and Fuzi (Aconite Lateral Root Prepared), they treat pi caused by excess of yin or yang. One uses Dahuang (Rhubarb Root) and Huanglian (Coptis Rhizome) to clear pre-existing damp-heat in the chest; the other adds Fuzi (Aconite Lateral Root Prepared) to simultaneously warm sudden deficiency-cold in the meridians. The method of steeping in boiling water and squeezing juice takes advantage of the nature of cold herbs without fire processing, resulting in potent action. The Fuzi (Aconite Lateral Root Prepared) must be decocted into juice separately, so that cold and hot properties act independently. The subtlety of Zhang Zhongjing's (Zhang Jingyue's predecessor, here referring to Zhang Zhongjing) legislative principles lies herein. Using Dahuang (Rhubarb Root), Huangqin (Scutellaria Root), and Huanglian (Coptis Rhizome) to purge evil heat from the stomach, while using Fuzi (Aconite Lateral Root Prepared) to warm and disperse congealed yin-cold, resolves the pathogenic factors of cold-heat entanglement in one stroke. How could later generations see these formulas and feel bewildered?
