治疗太阳病桂枝证，医生反而使用攻下法，导致腹泻不止、喘息且出汗的情况：
葛根（半斤，性味甘平） 甘草（二两，炙过，性味甘平） 黄芩（三两，性味苦寒） 黄连（三两，性味苦寒）
以上四味药，用水八升，先煮葛根，减少二升水量后，加入其余药物，煮取二升药液，去渣，分两次温服。
按成无己的说法，《内经》记载：“甘味发散属阳”，表证未解者，用葛根、甘草的甘味来发散；里气虚弱者，用黄芩、黄连的苦味来坚阴固里。
使用葛根（十五两）、升麻、白芍药、甘草（各三两），研为细末，每次服用三钱，水煎去渣，热服，每日三次。用于治疗小儿伤寒、疹病、时气、瘟疫引起的头痛、发热、肢体烦痛，以及疮疹发出之前或之后疑似阶段，均适宜服用。海藏说，如果病情未愈，可用连须葱白汤；再无效，则用葛根升麻汤。这是因为担心邪气从太阳经传入阳明经，所以用此汤截断其路径。然而，不知升麻并非太阳经的药物。如果有人在初患太阳病证时就给予葛根升麻汤，这不仅遗漏了对太阳经的治疗，反而引动太阳邪气内入于阳分，其产生的变证怎能说得尽呢？
This is Xiaochaihu Decoction (Minor Bupleurum Decoction) with added Huanglian (Coptidis Rhizoma), Baishao Yao (Paeoniae Radix Alba), Xuanshen (Scrophulariae Radix), and Shengma (Cimicifugae Rhizoma), used to treat fever manifesting in the skin, tidal fever, alternating chills and fever, bitter taste in the mouth, dry throat, dizziness, chest fullness, vexation, dry retching, thirst with vexation, and cough. Another variation adds Zhizi (Gardeniae Fructus) and Mudanpi (Moutan Cortex).
This is Xiaochaihu Decoction (Minor Bupleurum Decoction) with Ren Shen (Ginseng Radix et Rhizoma) removed, and added Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Qingpi (Citri Reticulatae Pericarpium Viride), Caoguo (Tsaoko Fructus), and Nongpo (Magnoliae Officinalis Cortex), used to treat Dan Nue (a type of malaria characterized by heat without cold), with a wiry and rapid pulse, presenting as fever without chills, or more heat than chills, dry mouth, and red, scanty, or difficult urination.

This involves combining this formula with Wuling San (Five-Ingredient Powder with Poria) to treat fever and diarrhea with interior deficiency.
This involves combining this formula with Pingwei San (Powder to Maintain the Normal State) to treat malaria.
This is Chai Ping Tang (Bupleurum and Pingwei Decoction) with Ren Shen (Ginseng Radix et Rhizoma) removed, and added Duhuo (Angelicae Pubescentis Radix), Qianhu (Peucedani Radix), Fuling (Poria), and Huoxiang (Agastaches Herba).

To treat Taiyang disease (Disease of the Taiyang Channel) presenting with Guizhi Syndrome (Cinnamon Twig Syndrome), where the physician erroneously applied purgation, resulting in persistent diarrhea, wheezing, and sweating:
Ge Gen (Kudzu Root, half jin, sweet and neutral) Gan Cao (Licorice Root, two liang, prepared/sweet and neutral) Huang Qin (Scutellaria Root, three liang, bitter and cold) Huang Lian (Coptis Rhizome, three liang, bitter and cold)
Take these four ingredients, add eight sheng of water, first decoct Ge Kan until the volume reduces by two sheng, then add the remaining herbs. Decoct to obtain two sheng of liquid, remove the dregs, and divide into two warm doses.
According to Cheng Wuji, citing the *Neijing* (Inner Canon): "Sweet flavors disperse and belong to Yang." When the exterior pathogen has not been resolved, use the sweetness of Ge Gen and Gan Cao to disperse; when the interior Qi is weak, use the bitterness of Huang Qin and Huang Lian to consolidate and secure the Yin.
Use Ge Gen (Fifteen liang), Sheng Ma (Cimicifugae Rhizoma), Baishao Yao (Paeoniae Radix Alba), and Gan Cao (Licorice Root, three liang each), grind into powder. Take three qian per dose, decoct with water, remove dregs, and take hot. Administer three times daily. Used to treat pediatric Shanghan (Cold Damage), Zhen Bing (Eruptive Diseases), Shi Qi (Seasonal Epidemic Qi), and Wen Yi (Warm Epidemics) presenting with headache, fever, and limb pain, as well as during the suspected phase before or after the eruption of sores/rashes. Haizang stated that if the condition persists, use Lian Xu Cong Bai Tang (Decoction of Scallion White with Roots); if still ineffective, use Ge Gen Sheng Ma Tang. This is done to intercept the pathogen from transferring from the Taiyang channel to the Yangming channel. However, one must realize that Sheng Ma is not a herb for the Taiyang channel. If Ge Gen Sheng Ma Tang is administered immediately upon the onset of Taiyang symptoms, it not only neglects the treatment of the Taiyang channel but also draws the Taiyang pathogenic factor inward into the Yang aspect. The resulting complications are incalculable.
