If abdominal pain occurs, add Ren Shen (Ginseng Radix et Rhizoma) 1 liang. If there is cold, add Gan Jiang (Dried Zingiberis Rhizoma) 1.5 liang. If there is thirst and desire for water, add Bai Zhu (Atractylodis Macrocephalae Rhizoma) 1.5 liang. If there is a pulsating sensation above the umbilicus, this indicates movement of Kidney Qi; remove Bai Zhu (Atractylodis Macrocephalae Rhizoma) and add Gui Zhi (Cinnamon Twig) 4 liang. If vomiting is frequent, remove Bai Zhu (Atractylodis Macrocephalae Rhizoma) and add Sheng Jiang (Fresh Zingiberis Rhizoma) 3 liang. If diarrhea is frequent, continue using Bai Zhu (Atractylodis Macrocephalae Rhizoma). If palpitations occur, add Fu Ling (Poria) 2 liang. If there are spasms and stiffness of the four limbs with abdominal pain, or abdominal fullness with diarrhea accompanied by muscle cramps, remove Bai Zhu (Atractylodis Macrocephalae Rhizoma) and add one raw Fu Zi (Aconiti Lateralis Radix Praeparata).
Crush the above herbs to the size of hemp seeds. For each dose of 3 qian, add 1.5 zhan of water, boil until reduced to 0.7 zhan, strain, and take warm. Administer three times daily.
Haicang stated: The eight methods of modification for Lizhong Tang (Spleen-Regulating Decoction) do not include any cold-natured herbs. If after vomiting and diarrhea there is an exterior syndrome, treat it by inducing sweating to release the exterior; if there is both vomiting and diarrhea, with free urination, profuse sweating, and internal cold with external heat, treat it with warming methods; as for after vomiting and purging, if sweating does not resolve the condition, and there is cold extremities with a pulse that is faint and about to disappear, Sini Tang (Frigid Extremities Decoction) is the primary treatment. From this, we know that this condition has no Yang syndromes, but only Yin syndromes. Zhongjing's Renshen Guizhi Tang (Ginseng and Cinnamon Twig Decoction) is Lizhong Tang (Spleen-Regulating Decoction) plus Guizhi (Cinnamon Twig), used when the Taiyang disease (Taiyang Syndrome) has not been resolved, and after mistaken purgation, results in Xiere Li (Heat-Coupling Diarrhea), epigastric stuffiness, and unresolved interior-exterior conditions; Huoren's book adds Qing Pi (Citri Reticulatae Pericarpium Viride) and Chen Pi (Citri Reticulatae Pericarpium) to this Lizhong Tang (Spleen-Regulating Decoction), naming it Zhizhong Tang (Middle-Regulating Decoction), which treats chest and diaphragm diseases; Xu Xueshi modified the formula from Huoren's book to create Bipi Wan (Spleen-Nourishing Pill), treating fatigue-induced spleen deficiency, following the principle of "tonifying the mother when deficient," similar to how a wealthy son ensures his father is not poor, not limited to just tonifying the mother organ in deficiency cases.
For the above three conditions, if there is external contraction combined with severe internal injury from drinking cold substances, Wuji San (Five Accumulations Powder) is appropriate.

Haicang said: Mr. Huangfu stated that Zhongjing expanded the Shanghan Lun's source text, Tangye Jinglun (Treatise on Decoctions), into ten volumes. Wen Lugong stated that Zhongjing is the ancestor of all formulas. Zhu Fengyi stated that Zhongjing's original Xixin Tang (Heart-Unblocking Decoction) lacked Huang Qin (Scutellariae Radix) in the Tangye Jinglun (Treatise on Decoctions), which was lost by later generations. Xu Xueshi also said that in Yi Yin's Tangye Jinglun (Treatise on Decoctions), Daxiehu Tang (Major Draining the Gallbladder Decoction) should have eight ingredients, but the current official edition lacks Da Huang (Rhei Radix et Rhizoma), having only seven, which is also a loss by later generations. From this, we know that Zhongjing's formulas all originate from the Tangye Jinglun (Treatise on Decoctions).
Sishun San (Four-Smooth Powder), Lizhong Tang (Spleen-Regulating Decoction), Sini Tang (Frigid Extremities Decoction), Tongmai Sini Tang (Pulse-Unblocking Frigid Extremities Decoction), Shu Fu Tang (Atractylodes and Aconite Decoction), Jiang Fu Tang (Zingiber and Aconite Decoction), Zhenwu Tang (True Warrior Decoction), and Baitong Tang (White Pass Decoction) are all found under Zhongjing's relevant entries.
The rest scattered in various formularies, all referred to as Zhongjing's formulas, are thus.
