治气用气药，枳壳利肺气，多服损胸中至高之气。青皮泻肝气，多服损真气。木香行中、
下焦气。香附快滞气。陈皮泻逆气。紫苏散表气。浓朴泻卫气，槟榔泻至高之气。藿香之馨香上
行胃气。沉香升降真气。脑麝散真气。若此之类，气实所宜。其中有行散者，有损泄者，其过剂
乎？用之能治气之标，而不能治气之本。其调气有木香，味辛气能上升，如转达而不达，固宜
用之。若阴火冲上而用之，则反助火邪矣，故必用黄柏、知母，而少用木香佐之。
For treating wind-cold (Shangfeng, 伤风), Fangfeng (Saposhnikoviae Radix) serves as the sovereign drug, with Gancao (Glycyrrhizae Radix et Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) as ministering drugs. The classics state: "Pungent and sweet flavors disperse and belong to Yang." Wind pathogens are suitable for pungent dispersal; since Fangfeng is pungent and a universal herb for treating wind, it is used as the sovereign drug. For treating cold damage (Shanghan, 伤寒), Gancao is the sovereign drug, with Fangfeng and Baizhu as ministering drugs; this indicates that cold pathogens are suitable for dispersion via sweet flavors. If there are other syndromes, select dosages from the previously mentioned syndrome-specific medications, arranging them according to the theory of Sovereign, Minister, Assistant, and Courier.
For sudden redness and swelling of the eyes, Fangfeng and Huangqin (Scutellariae Radix) are used as sovereign drugs to drain fire; Huanglian (Coptidis Rhizoma) and Danggui (Angelicae Sinensis Radix) are used as assistant drugs to harmonize blood, combined with herbs specific to each meridian. For chronic eye conditions causing dim vision, Shudihuang (Rehmanniae Radix Praeparata) and Danggui are used as sovereign drugs, Qianghuo (Notopterygii Rhizoma et Radix) and Fangfeng as ministering drugs, and Gancao and Ganju (Chrysanthemi Flos) as assistant drugs. For dysentery accompanied by abdominal pain, Shaoyao (Paeoniae Radix Alba) and Gancao are used as sovereign drugs, Danggui and Baizhu as assistant drugs; the presence and sequence of blood in stool are analyzed based on heat in the Triple Burner (Sanjiao, 三焦). For watery diarrhea, Fuling (Poria) and Baizhu are used as sovereign drugs, Shaoyao and Gancao as assistant drugs. For various wind diseases, Fangfeng is the sovereign drug, with assistants selected according to the specific disease.
For cough, Wuweizi (Schisandrae Fructus) is the sovereign drug; if phlegm is present, Banxia (Pinelliae Rhizoma) is added as an assistant; if wheezing occurs, Ejiao (Asini Corii Colla) is added as an assistant; if there is heat without phlegm, Huangqin is added as an assistant; only the dosage varies. For difficult urination, Huangbai (Phellodendri Cortex) and Zhimu (Anemarrhenae Rhizoma) are used as sovereign drugs, Fuling and Zexie (Alismatis Rhizoma) as assistant drugs. For dampness in the Lower Jiao (Xiajiao, 下焦), Longdancao (Gentianae Radix) and Fangji (Stephaniae Tetrandrae Radix) are used as sovereign drugs, Gancao as an assistant. For hemorrhoids and fistulas, Cangzhu (Atractylodis Rhizoma) and Fangfeng are used as sovereign drugs, Gancao and Shaoyao as assistant drugs, with modifications based on detailed differentiation of other syndromes. For various sores and ulcers, Huanglian and Danggui are used as sovereign drugs, Gancao and Huangqin as assistant drugs. For malaria, Chaihu (Bupleuri Radix) is the sovereign drug, with meridian-guiding herbs added as assistants according to the time of onset and its corresponding meridian.
When treating Qi disorders using Qi-regulating herbs, Zhike (Aurantii Fructus Immaturus) benefits Lung Qi, but excessive use damages the supreme Qi in the chest. Qingpi (Citri Reticulatae Pericarpium Viride) drains Liver Qi, but excessive use damages True Qi. Muxiang (Aucklandiae Radix) promotes the movement of Qi in the Middle and Lower Jiao. Xiangfu (Cyperi Rhizoma) relieves stagnant Qi. Chenpi (Citri Reticulatae Pericarpium) descends rebellious Qi. Zisu (Perillae Folium) disperses exterior Qi. Houpo (Magnoliae Officinalis Cortex) drains Defensive Qi, and Binglang (Arecae Semen) drains supreme Qi. Huoxiang (Agastachis Herba) uses its aromatic nature to direct Stomach Qi upward. Chenxiang (Aquilariae Lignum Resinatum) regulates the ascending and descending of True Qi. Nao She (Moschus) dissipates True Qi. Such herbs are suitable for excess patterns of Qi. Among them, some promote circulation and dispersion, while others damage and drain; are they not used in excessive doses? They can treat the branch manifestations of Qi disorders but cannot treat the root. To regulate Qi, Muxiang can be used; its pungent flavor and ascending nature make it suitable when Qi stagnation fails to resolve. However, if Yin Fire (Yin Huo, 阴火) rushes upward and Muxiang is used, it will instead assist the pathogenic fire. Therefore, Huangbai and Zhimu must be used, with a small amount of Muxiang added as an assistant.
