【丹皮】
气味寒。味辛。无毒。主治寒热、中风、抽搐、惊痫。能祛除邪气，消除症坚和瘀血，清除滞留于肠胃的积滞。
安养五脏。治疗痈疮。
丹皮气味寒，禀受自然界冬季寒冷的水气，归入手太阳寒水小肠经。味辛且无毒，得自西方金的气味，归入手太阴肺经。其气味下降多于上升，属阴。寒水太阳经，运行于体表，作为外部的屏障。若太阳经阴虚，则皮毛不致密，外部屏障不坚固，表邪从外侵入而导致寒热症状。丹皮之所以能主治这些症状，是因为其气寒可以清热，味辛可以散寒解表。肝是风木之脏。若肺经不能制约肝木，肝风挟带浊火上逆，就会发生中风、抽搐、惊痫等症状。丹皮辛寒，能补益肺气、平抑肝木。肝气不再上逆而肺气下降，各种症状即可平息。小肠是受盛之官，与心互为表里。心主血，若血热下注，滞留于小肠，瘀积形成瘕块，质地坚硬且可被察觉。丹皮性寒可清热，味辛可散结，所以能入小肠而消除瘕块。五脏是藏精气的脏器。辛寒之性能清血分之热，血液清净则阴液充足，五脏得以安宁。营血逆行于肌肉腠理之间，便会生发痈疮。丹皮辛寒，可以消散血分之热，所以能调和营血而治疗痈疮。
制方：
丹皮与防风研成末，用酒送服。治疗癞疝。
丹皮同麦冬、五味子、白茯苓、甘草、木通、生地一起使用。治疗心包络之火。
【黄连】
气味寒。味苦。无毒。主治热气引起的目痛、流泪损伤、明目。治疗肠中腹痛、下痢。治疗妇人阴部肿痛。
长期服用使人不忘事。（炮制方法：用吴茱萸炒，再用姜汁炒）
黄连气味寒，禀受自然界冬季寒冷的水气，归入足少阴肾经。味苦且无毒，得自南方火的气味，归入手少阴心经。
其气味均主下降，属阴。它主治热气引起的目痛，是因为心主火，火气热，心病传舍于肝，而肝开窍于目。黄连苦寒，所以能清火。手少阴心经的正脉，出于面部，会合于目内眦。手少阴经对应心火，火盛则心系拘急而流泪。流泪损伤皆因心火所致。黄连清心火，所以能主治此症。根据“实则泻其子”的原则，心是肝木之子。清心火则肝之邪气得以泻除，所以能明目。大肠是庚金之腑，若心火乘袭大肠，则津液化为脓血，导致疼痛和下痢。黄连之所以能主治这些症状，是因为其性寒以清火，味苦以泄热。北方色黑，通应于肾，开窍于二阴。妇人阴部乃肾之窍也。热盛则肿胀，肿痛是由于火盛所致。黄连入肾经，以其寒苦之性清火，所以能主治此症。至于长期服用使人不忘事，是因为黄连入心清火，火清则心神清明，能够记忆。
制方：
黄连同西河柳、黄芩、黄柏、石膏、知母、甘草一起使用。治疗痧疹已透发但烦躁不止。
黄连同当归、枣仁、圆肉（龙眼肉）、生地、黄芩、黄柏、黄芩（原文重复或指代其他黄芩类，此处依原文列出）一起使用。治疗火症盗汗。
黄连同槐花、枳壳、乳香、没药一起使用。治疗痢疾纯血且腹痛。

[Mudanpi (Moutan Cortex)]
Qi is cold. Flavor is acrid. Non-toxic. It primarily treats chills and fever, wind-stroke, convulsions, and epilepsy. It expels pathogenic factors, eliminates masses (zheng) and hard accumulations, and resolves blood stasis remaining in the intestines and stomach.
It calms the five zang organs and treats carbuncles and sores.
Mudanpi has a cold qi, inheriting the cold water energy of winter from heaven, entering the Hand-Taiyang Cold-Water Small Intestine Meridian. Its acrid flavor and non-toxic nature derive from the metal flavor of the West on earth, entering the Hand-Taiyin Lung Meridian. The descending aspect of its qi and flavor exceeds the ascending, making it Yin. The Cold-Water Taiyang Meridian circulates on the body's surface, serving as an external defense. If the Taiyang Meridian suffers from Yin deficiency, the skin and hair pores become loose, and the external defense becomes insecure, allowing exterior pathogens to enter from outside, resulting in chills and fever. Mudanpi treats these conditions because its cold qi clears heat, and its acrid flavor disperses cold and releases the exterior. The Liver is the organ of Wind-Wood. If the Lung Meridian fails to control the Liver, Liver wind carrying turbid fire rebels upward, giving rise to symptoms of wind-stroke, convulsions, and epilepsy. Mudanpi, being acrid and cold, benefits the Lung and pacifies the Liver. When Liver Qi no longer rises and Lung Qi descends, all symptoms subside. The Small Intestine is the official of reception and transformation, interiorly-exteriorly related to the Heart. The Heart governs Blood; if Heat in the Blood flows downward and remains in the Small Intestine, stasis accumulates to form a mass (jia), which is hard and palpable. Mudanpi’s cold nature clears heat, and its acrid nature dissipates nodules, thus entering the Small Intestine to eliminate masses. The Five Zang Organs store Yin essence. Acrid and cold properties clear the blood; when the blood is pure, Yin is sufficient, and the Zang organs are at peace. When Ying (Nutritive) Blood reverses into the muscle tissue, carbuncles and sores arise. Mudanpi, being acrid and cold, can dissipate Heat in the Blood, thereby harmonizing Ying and treating carbuncles and sores.
Prescriptions:
Mudanpi mixed with Fangfeng powder and taken with wine. Treats leprosy-like hernias.
Mudanpi combined with Maidong, Wuweizi, Baifu Ling, Gancao, Mutong, and Shengdi. Treats Fire in the Pericardium.
[Huanglian (Coptidis Rhizoma)]
Qi is cold. Flavor is bitter. Non-toxic. It primarily treats eye pain caused by Heat, tearing due to injury, improves vision, treats abdominal pain in the intestines, dysentery, and swelling and pain in the female genitalia.
Long-term use prevents forgetfulness. (Preparation: Stir-fry with Evodiae Fructus, then stir-fry with Ginger Juice.)
Huanglian has a cold qi, inheriting the cold water energy of winter from heaven, entering the Foot-Shaoyin Kidney Meridian. Its bitter flavor and non-toxic nature derive from the Fire flavor of the South on earth, entering the Hand-Shaoyin Heart Meridian.
Both its qi and flavor descend, making it Yin. It treats eye pain caused by Heat because the Heart governs Fire; Fire Qi is hot. Heart disease transmits to the Liver, and the Liver opens into the eyes. Huanglian is bitter and cold, thus clearing Fire. The regular pathway of the Hand-Shaoyin meridian emerges from the face and converges at the inner canthus. The Hand-Shaoyin corresponds to Heart Fire; when Fire is excessive, the Heart ties become tense, leading to tearing. Injury to tears is all due to Heart Fire. Huanglian clears the Heart, thus treating this condition. According to the principle "excess is treated by draining its child," the Heart is the child of Liver Wood. Clearing Heart Fire drains Liver pathogenic factors, thus improving vision. The Large Intestine is the fu-organ of Geng Metal. If Heart Fire attacks it, body fluids transform into pus and blood, causing pain and dysentery. Huanglian treats these because its cold nature clears Fire, and its bitter nature drains Heat. The North is black, connecting to the Kidney, opening into the two orifices. The female genitalia is the orifice of the Kidney. Excessive Heat causes swelling; swelling and pain are due to excessive Fire. Huanglian enters the Kidney, using its cold and bitter nature to clear Fire, thus treating this condition. As for long-term use preventing forgetfulness, it is because Huanglian enters the Heart to clear Fire; when Fire is cleared, the Heart becomes bright, enabling memory.
Prescriptions:
Huanglian combined with Xihe Liu, Huangqin, Huangbai, Shigao, Zhimu, and Gancao. Treats persistent irritability after rash eruption.
Huanglian combined with Danggui, Zaoren, Yuanrou, Shengdi, Huangqin, Huangbai, and Huangqin. Treats night sweats due to Fire syndromes.
Huanglian combined with Huaihua, Zhike, Ruxiang, and Moyao. Treats dysentery with pure blood and abdominal pain.
