Gancao (Radix Glycyrrhizae Preparata) two liang (roasted with honey), Ganjiang (Rhizoma Zingiberis Preparata) one and a half liang, Fuzi (Radix Aconiti Lateralis Preparata) one piece (used raw, skin removed, cut into eight slices).
The above three ingredients are decocted in three sheng of water until reduced to one sheng and two he. The dregs are strained out [method], and the liquid is divided into two doses and taken warm. For robust individuals, a large Fuzi (Radix Aconiti Lateralis Preparata) one piece and Ganjiang (Rhizoma Zingiberis Preparata) three liang may be used.
"Sini" refers to cold extremities; the formula is named after this syndrome. It is used for all cases involving Jue (cold limbs) in mixed Taiyin, Shaoyin, or Yangming syndromes combined with Yang channel involvement. Thus, it is used in Shaoyin disease to rescue the Yuanhai (the source of true Yang in the Kidney); its action is gentle and lingering, retaining medicinal power within the body, serving as an excellent method to summon dispersed Yang Qi outward.
Gancao (Radix Glycyrrhizae Preparata) two liang (roasted with honey), Fuzi (Radix Aconiti Lateralis Preparata) one large piece (used raw, skin removed, broken into eight pieces), Ganjiang (Rhizoma Zingiberis Preparata) three liang (robust individuals may use four liang).

Tongmai Sini Tang (Pulse-Reviving Four-Reversal Decoction) is used for Shaoyin Geyang syndrome (rebellious Yang), characterized by facial redness and impending Yang collapse. Urgent use of Ganjiang (Rhizoma Zingiberis Preparata) and raw Fuzi (Radix Aconiti Lateralis Preparata) acts like bursting through a door to rapidly dispel Yin-cold pathogens, while Gancao (Radix Glycyrrhizae Preparata) moderates the properties of Jiang and Fu... regarding the pulse...

The above four ingredients are decocted in three sheng of water until reduced to one sheng and two he. The dregs are strained out [method], and the liquid is divided into two doses and taken warm.
Sini Jia Renshen Tang (Four-Reversal Decoction plus Ginseng) treats Yin collapse with cessation of diarrhea. Since Yin collapse causes Yang Qi to depart with it, treatment should not focus solely on nourishing Yin, but rather employ Ganjiang (Rhizoma Zingiberis Preparata) and Fuzi (Radix Aconiti Lateralis Preparata)...
