Erchen Tang (Decoction of Two Aged Ingredients; see Phlegm-Fluids chapter) with the addition of four qian of Shengjiang (Fresh Ginger Rhizome) as the principal ingredient, can transform routine treatment into miraculous efficacy, with effects as if divine.

Tongcao Jupi Tang (Passiflora and Tangerine Peel Decoction; from *Qianjin Fang*) treats vomiting and rebellious qi due to stomach heat in Shanghan (Cold Damage).
Ingredients: Tongcao (Passiflorae Caulis) 2 qian, Jupi (Citri Reticulatae Pericarpium) 1.5 qian, Jingmi (Oryza Sativa Glutinosa Semen) a pinch, Sheng Lugen Zhi (Juice of Fresh Phragmitis Rhizoma) one cup.
Administration: Decoct in water and take hot.
If Tongcao and Jupi are removed and Zhuru (Bambusae Caulis in Taeniam) and Shengjiang Zhi (Fresh Ginger Juice) are added, it is named Lugan Yin (Phragmitis Drink) in *Qianjin Fang*, treating vomiting, hiccups, regurgitation, and dry heaving after Shanghan.

Zhu Danxi stated: "For patients suffering from vomiting, Guolou Shi (Trichosanthis Fructus), Taoren (Persicae Semen), Laifuzi (Raphani Semen), Shanzhi (Gardeniae Fructus), and all oily substances are contraindicated, as they violate the Stomach and induce vomiting."

Zhang Jingyue stated: "Patients with vomiting should also avoid Cangzhu (Atractylodis Rhizoma), because its impure flavor tends to provoke vomiting."

The ascending and descending of Qi, whether pathogenic or healthy, invariably passes through the Shaoyang (Lesser Yang) channel, as Shaoyang is the pathway of Yin and Yang. When Yin and Yang contend, abdominal pain results. The formula uses Chuanxiong, Danggui, and Shaoyao to harmonize Yin blood, Shengjiang to unblock Yang Qi, Banxia to calm the Stomach, and Gancao to benefit the Spleen, thereby resolving the contention between Yin and Yang, and the abdominal pain heals. When Qi ascends, heat occurs; the formula uses Li Gen Bai Pi to descend Qi. When Qi descends, cold occurs; the formula uses Sheng Gegen to ascend fluids. With proper regulation of ascending and descending, chills and fever heal. Moreover, Huangqin alone is a specific herb for Shaoyang disorders. Observing that major and minor Xiaochaihu Tangs in *Shanghan Lun* both employ this herb, it is evident that amidst myriad variations, adhering strictly to the Six Channels differentiation ensures no deviation whatsoever.
