凡解利伤风,以防风为君,甘草、白术为佐。经云∶辛甘发散为阳。风宜辛散,防风味辛及
治风通用,故以为君。凡解利伤寒,以甘草为君,防风、白术为佐,是寒宜甘发也。或有别证,
于前随证治病药内选用分两,
以君臣论。凡眼暴发赤肿,以防风、黄芩为君,以泻火,以黄连、当归根和血为佐,兼以各经
药用之。凡眼久病昏暗,熟地黄、归根为君,羌活、防风为臣,甘草、甘菊为佐。凡痢疾腹痛,
以芍药、甘草为君,当归、白术为佐,见血先后,以三焦热论。凡水泻,以茯苓、白术为君,
芍药、甘草为佐。凡诸风,以防风为君,随治病为佐。凡嗽以五味子为君,有痰者以半夏为佐,
喘者以阿胶为佐,有热无痰以黄芩为佐,但分两多寡不同耳。凡小便不利,以黄柏、知母为君,
茯苓、泽泻为佐。凡下焦有湿,草龙胆、防己为君,甘草为佐。凡痔漏,以苍术、防风为君,甘
草、芍药为佐,详别证加减。凡诸疮,以黄连、当归为君,甘草、黄芩为佐。凡疟以柴胡
为君,随所发时属经,分用引经药佐。
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。
凡是治疗伤风,以防风为君药,甘草、白术为佐药。医经说:辛味和甘味的药物配合具有发散作用,属于阳的性质。风邪适宜用辛散的方法治疗,防风味道辛且是治疗风病的通用药物,所以作为君药。凡是治疗伤寒,以甘草为君药,防风、白术为佐药,这是寒邪适宜用甘味发散的缘故。如果有其他证候,在前面的随证治病药物中选用剂量,按照君臣佐使的理论来安排。
凡是眼睛突然发红肿胀,以防风、黄芩为君药,用来泻火;以黄连、当归为佐药,用来调和血液,并兼用各经络的药物。凡是眼睛久病导致视物昏暗,以熟地黄、当归为君药,羌活、防风为臣药,甘草、甘菊为佐药。凡是痢疾伴有腹痛,以芍药、甘草为君药,当归、白术为佐药,根据是否有便血及其先后顺序,从三焦有热的角度来论治。凡是水样腹泻,以茯苓、白术为君药,芍药、甘草为佐药。凡是各种风病,以防风为君药,根据具体病症选择佐药。
凡是咳嗽,以五味子为君药,有痰的加半夏为佐药,气喘的加阿胶为佐药,有热无痰的加黄芩为佐药,只是剂量多少有所不同罢了。凡是小便不通利,以黄柏、知母为君药,茯苓、泽泻为佐药。凡是下焦有湿邪,以龙胆草、防己为君药,甘草为佐药。凡是痔疮漏管,以苍术、防风为君药,甘草、芍药为佐药,详细辨别其他证候进行加减。凡是各种疮疡,以黄连、当归为君药,甘草、黄芩为佐药。凡是疟疾,以柴胡为君药,根据发作时间所属的经络,分别使用引经药作为佐药。
治疗气病使用理气药,枳壳能疏通肺气,多服会损伤胸中至高之气。青皮能泻肝气,多服会损伤真气。木香能通行中、下焦的气机。香附能疏畅郁滞之气。陈皮能降逆气。紫苏能疏散表气。厚朴能泻卫气,槟榔能泻至高之气。藿香的香气能使胃气上行。沉香能升降真气。麝香能耗散真气。像这类药物,适用于气实证。其中有的行气散结,有的损泄正气,难道不是过量了吗?这些药只能治疗气病的表象,而不能治疗气病的根本。调理气机可以用木香,它味辛,气性能上升,如果气机阻滞而不得通达,固然应该使用它。如果是阴火上冲,却使用了它,反而会助长火邪,所以必须用黄柏、知母,并少量用木香作为佐药。
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.
