内外、外感热而成斑者。此方主之。
内伤则里热，外感则表热，两热而无泄，故令斑烂。外伤者调其中，苍、陈、砂、藿、
半、芍、枳、桔，皆调中药也；外感者疏其表，麻、桂、羌、芎、芷、草，皆疏表药也。表
里治而斑自愈矣。

中气不足，无根失守之火，出于肌表而成斑者，此方主之。
此是汗、吐、下后之证。中气虚乏，则余邪无所归附，隐隐然见于肌表，其色淡红而不
甚显为辨也。人参、黄 所以补中，半夏、甘草所以调中，此皆健脾药也；复有当归、芍药
之活血，则外溢之斑流而不滞；有桂心、附子之温中，则失位之火引而归原，此中营之帜一
端，而失伍之师各就其列也。是方也，以附、桂、参、 而治斑，法之变者也。医而未至于
可以权，则不足以语此。
叙曰∶疟之理难言矣。知五运六气、十四经络，始能粗知其证。知阴阳进退消长之理，
然后知夫疟疾变迁之妙。苟非精研斯道，则所知者肤浅而已，一有问难，犹然袖手解颐。今
考名方十八首，说证用药，可为初学之启蒙也。
Cangzhu (Atractylodis Rhizoma, 1.5 qian) Chenpi (Citri Reticulatae Pericarpium), Sharen (Amomi Fructus), Huoxiang (Agastaches Herba), Gancao (Glycyrrhizae Radix et Rhizoma), Shaoyao (Paeoniae Radix, stir-fried), Jiegeng (Platycodonis Radix), Banxia (Pinelliae Rhizoma), Baizhi (Angelicae Dahuricae Radix), Zhike (Aurantii Fructus Immaturus, stir-fried).
Qianghuo (Notopterygii Rhizoma et Radix, 1 qian each), Chuanxiong (Ligusticum Chuanxiong Rhizoma), Mahuang (Ephedrae Herba), Guizhi (Cinnamomi Ramulus, 0.5 qian each).
Indicated for macules or rashes resulting from heat accumulation due to both internal injury and external contraction. This formula is the primary treatment for such conditions.
Internal injury leads to interior heat, while external contraction leads to exterior heat. If neither heat can be vented, it results in macular eruptions. For cases caused by external factors affecting the interior, one must regulate the Middle Jiao; Cangzhu, Chenpi, Sharen, Huoxiang, Banxia, Shaoyao, Zhike, and Jiegeng are all herbs that regulate the Middle Jiao. For cases caused by external pathogens, one must disperse the exterior; Mahuang, Guizhi, Qianghuo, Chuanxiong, Baizhi, and Gancao are all herbs that disperse the exterior. By treating both the exterior and the interior, the macules will heal spontaneously.
Renshen (Ginseng Radix), Huangqi (Astragali Radix, honey-fried), Danggui (Angelicae Sinensis Radix), Shaoyao (Paeoniae Radix, wine-stir-fried), Guixin (Cinnamomi Cortex), Gancao (Glycyrrhizae Radix et Rhizoma, honey-fried), Banxia (Pinelliae Rhizoma, processed), Heifuzi (Aconiti Lateralis Radix Praeparata).
Indicated for macules arising on the skin surface due to rootless fire losing its control because of deficiency of Middle Qi. This formula is the primary treatment for such conditions.
This syndrome occurs after treatments involving sweating, vomiting, or purging. When Middle Qi is deficient and lacking, residual pathogenic factors have no place to attach, appearing faintly on the skin surface with a pale red color that is not very prominent, which serves as a distinguishing feature. Renshen and Huangqi tonify the Middle; Banxia and Gancao harmonize the Middle; these are all Spleen-strengthening herbs. Additionally, Danggui and Shaoyao invigorate blood circulation, ensuring that extravasated macules flow smoothly without stagnation. Guixin and Fuzi warm the Middle, guiding the displaced fire back to its origin. This is like raising the banner of the central camp so that scattered troops return to their ranks. Using Fuzi, Guizhi, Renshen, and Huangqi to treat macules represents a variation in therapeutic method. A physician who has not reached the level of flexible adaptation cannot discuss this approach.
Preface: The principles of malaria are difficult to articulate fully. Only by understanding the Five Movements and Six Qi, and the fourteen meridians, can one roughly comprehend its manifestations. Only by comprehending the principles of the advance and retreat, waxing and waning of Yin and Yang, can one appreciate the subtleties of malaria's progression. Unless one meticulously studies this discipline, knowledge remains superficial; when questioned, one would merely stand idle and smile helplessly. Herein, eighteen famous formulas are examined, with explanations of syndromes and medication, serving as an introductory guide for beginners.
