主伤寒腹中急痛。
胶饴（一升） 甘草（一两，炙） 桂枝（三两，去皮） 芍药（六两） 大枣（十二枚，去核）
生姜（三两，切） 水七升，煮三升，去滓，纳胶饴，微火消解，温服一升，日三服。呕家不用建中，
恐甘缓在上也。
阳气传太阴而痛，其症有二，腹满便闭按之痛者，实也，宜下之。肠鸣泄利而痛者，虚也，
宜与建中汤。成氏曰∶脾应中央，一有不调，则荣卫失所育，津液失所行，必以此汤温建中脏，
故建中名焉。胶饴甘温，甘草甘平，脾欲缓急食甘以缓之，故
以饴为君，甘草为臣，桂枝辛热辛散也，润也。荣卫不足润而散之，芍药酸寒，酸收
也，泄也。津液不逮，收而行之，是以桂枝、芍药为佐，生姜辛温，大枣甘温，胃
者，卫之源，脾者，荣之本，卫为阳，益之必以辛，荣为阴，补之必以甘辛，甘相合，
脾胃健而荣卫通，是以姜枣为使。

Indicated for abdominal urgency and pain caused by Shanghan (Cold Damage).
Yi Tang (Maltose) (1 sheng) Gan Cao (Glycyrrhizae Radix et Rhizoma, 1 liang, honey-fried) Gui Zhi (Cinnamomi Ramulus, 3 liang, bark removed) Shao Yao (Paeoniae Radix Alba, 6 liang) Da Zao (Ziziphi Jujubae Fructus, 12 pieces, pits removed)
Sheng Jiang (Zingiberis Rhizoma Recens, 3 liang, sliced) Add 7 sheng of water, decoct to obtain 3 sheng, remove the dregs, add Yi Tang, dissolve over low heat, take 1 sheng warm, three times a day. Patients with vomiting should not use Jianzhong Tang (Middle-Jian Decoction),
as it is feared that the sweet and cloying nature may cause Qi to stagnate in the upper jiao.
When Yang Qi transmits to the Taiyin channel causing pain, there are two types of symptoms: abdominal fullness, constipation, and pain upon pressure indicate excess syndrome, which is suitable for purgation. Bowel sounds, diarrhea, and pain indicate deficiency syndrome,
which is suitable for treatment with Jianzhong Tang. Cheng Wuji stated: The Spleen corresponds to the Central Earth element; once its function is disordered, Ying (Nutritive) and Wei (Defensive) Qi lose their source of nourishment, and body fluids lose their proper circulation. It is necessary to use this decoction to warm and establish the Middle Jiao (Central Burner) Zang-Fu organs,
hence the name Jianzhong. Yi Tang is sweet and warm, Gan Cao is sweet and neutral. The Spleen desires relief from tension; eating sweet foods can relieve tension. Therefore,
Yi Tang is used as the Sovereign (Jun) herb, and Gan Cao as the Minister (Chen) herb. Gui Zhi is acrid and hot, possessing dispersing properties, yet also moistening. When Ying and Wei Qi are insufficient, they are regulated through moistening and dispersing. Shao Yao is sour and cold, possessing astringent properties, and also draining effects. When body fluid circulation is inadequate, astringency and guidance promote its movement. Thus, Gui Zhi and Shao Yao serve as Assistant (Zuo) herbs. Sheng Jiang is acrid and warm, Da Zao is sweet and warm. The Stomach is the source of Wei Qi, and the Spleen is the root of Ying Qi. Wei Qi belongs to Yang; tonifying it requires acrid flavors. Ying Qi belongs to Yin; tonifying it requires a combination of sweet and acrid flavors. The combination of sweet and acrid flavors strengthens the Spleen and Stomach, allowing Ying and Wei Qi to flow freely. Therefore, Sheng Jiang and Da Zao act as Envoy (Shi) herbs.
Pu Ji Xiao Du Yin (Universal Benefit Decoction to Eliminate Toxins)

Indicated for Lianggan Shanghan (Simultaneous contraction of exterior and interior channels in Cold Damage), as well as pathogenic factors from abnormal seasonal climates, manifesting as aversion to cold with high fever, headache and body ache, thirst, where symptoms are similar among many people.

Decoct with Sheng Jiang (Zingiberis Rhizoma Recens) and Cong Bai (Allii Fistulosi Bulbus) in water, and take orally.
Wu Kun stated: When there is climate inappropriate to the season, illness affects both young and old with similar presentations. Acrid herbs derive the Metal Qi of Heaven and Earth, which manifests as "Righteousness" (Yi) in humans,
thus enabling them to support healthy Qi and expel pathogenic factors. Qiang Huo, Cang Zhu, Xi Xin, Chuan Xiong, and Bai Zhi are all acrid substances. For pathogens in the Taiyang channel, treat with Qiang Huo; for pathogens in the Yangming channel, treat with Bai Zhi; for pathogens in the Shaoyang channel, treat with Huang Qin; for pathogens in the Taiyin channel, treat with Cang Zhu; for pathogens in the Shaoyin channel, treat with Xi Xin; for pathogens in the Jueyin channel, treat with Chuan Xiong. Fang Feng acts as the vanguard among these herbs. Sheng Di Huang clears heat from the blood level. Gan Cao harmonizes the various herbs and clears heat from the Qi level. Yi Lao's preface states: In winter, it treats cold; in summer, it treats heat; in spring, it treats warmth; in autumn, it treats dryness. It is an army responding to all fronts. However, it is not suitable for individuals with Yin deficiency and weak Qi.
