【槐花】
气味平和。味道甘甜。没有毒性。主治五种痔疮、心痛、眼睛发红，能杀灭腹内脏腑中的寄生虫，以及治疗皮肤风热、肠风便血、赤白痢疾，均炒制后研末服用。
槐花气味平和，禀受秋天清凉的金气，归属于手太阴肺经；味道苦且无毒，得自南方火地的火味，归属于手少阴心经。
气味都主沉降，属阴。肺与大肠互为表里，五种痔疮是大肠的火证。槐花味苦能清心，所以主治此症。火郁结在心则引起疼痛，气平能清热，味苦能泄降，所以主治此症。眼睛发红，是肝有实火。根据“实则泻其子”的原则，味苦能清心，心是肝的子脏，故可治之。腹部是足太阴脾经运行的地方，脏腑即指大肠，是大肺的相合之腑。味苦可以杀虫，所以主治此症。皮肤是肺的外合，气平能清风邪，味苦能泄热，所以主治此症。肠风下血，是大肠火盛所致。赤白痢疾，是大肠湿热所致。味苦能清热，所以都炒制后研末服用。
制方方法：
槐花同荆芥一起使用，治疗下部出血；同牡蛎粉一起使用，治疗白带。
【黄柏】
气味寒凉。味道苦。没有毒性。主治五脏肠胃中的结热、黄疸、肠痔，止住泄痢，治疗女子漏下赤白及阴部损伤蚀疮。（用盐水炒制）
黄柏气味寒凉，禀受冬天寒冷的水气，归属于足少阴肾经；味道苦且无毒，得自南方火地的火味，归属于手少阴心经。
气味都主沉降，属阴。五脏六腑中，心为君主。心属火，结热即是火气郁结。味苦能泄热，所以主治此症。黄疸，是胃经湿热的病症。肠痔，是大肠火气郁结的疾病。泄痢，是大肠湿热的病症。黄柏之所以能主治这些病症，是因为它入肾经。肾是胃的关口，大肠由肾所主。气寒能清热，味苦能燥湿，所以能治疗以上各种病症。漏下赤白，包括胎漏下血及赤白带下。一是因为血热妄行，一是因为湿热下注。黄柏入肾，寒性能清热，苦性可燥湿，所以主治此症。阴阳蚀疮，是指阴户受伤腐蚀成疮。所有的疮疡都属于心火，黄柏之所以能主治，是因为其苦寒之性能泻火。
制方方法：
黄柏同知母一起使用，滋阴降火；同茅术（苍术）一起使用，除湿清热，是治疗痿证的要药；同细辛一起使用，泻膀胱之火，需用蜜炙后研成粉末。
煨大蒜丸，治疗妊娠期间下痢白色脓血；同木瓜、白茯苓、二术（苍术、白术）、石斛、生地一起使用，治疗痿证；同白芍、甘草一起使用，治疗火热引起的腹痛。
[Huaihua (Sophorae Flos)]
The qi is neutral. The taste is sweet. It is non-toxic. It primarily treats five types of hemorrhoids, heart pain, red eyes, kills parasites in the abdominal viscera, and addresses wind-heat on the skin, intestinal wind with bloody stool, and dysentery with red and white discharge. All are used after being stir-fried and ground into powder.
Huaihua has a neutral qi, inheriting the cooling metal energy of autumn, entering the Hand-Taiyin Lung Meridian. Its taste is bitter and non-toxic, deriving from the fire flavor of the southern earth, entering the Hand-Shaoyin Heart Meridian.
Both its qi and taste are descending, belonging to Yin. The Lung and Large Intestine are exterior-interior partners; the five types of hemorrhoids are fire syndromes of the Large Intestine. Huaihua’s bitter taste clears the Heart, thus treating this condition. Fire stagnating in the Heart causes pain; neutral qi can clear heat, and bitter taste can drain downward, thus treating this condition. Red eyes indicate excess fire in the Liver. According to the principle "when there is excess, drain its child," the bitter taste clears the Heart, which is the child organ of the Liver, thereby treating it. The abdomen is the pathway of the Foot-Taiyin Spleen Meridian; the viscera here refers to the Large Intestine, which is the interior partner of the Lung. Bitter taste can kill parasites, thus treating this condition. The skin is the exterior extension of the Lung; neutral qi can disperse wind, and bitter taste can drain heat, thus treating this condition. Intestinal wind with bloody stool is caused by fire in the Large Intestine. Dysentery with red and white discharge is caused by damp-heat in the Large Intestine. Bitter taste can clear heat, so they are all stir-fried and taken as powder.
Prescription Methods:
Huaihua combined with Jingjie (Schizonepetae Herba) treats lower bleeding; combined with Muli (Ostreae Concha) powder treats leukorrhea.
[Huangbai (Phellodendri Cortex)]
The qi is cold. The taste is bitter. It is non-toxic. It primarily treats accumulated heat in the five viscera and intestines/stomach, jaundice, intestinal hemorrhoids, stops diarrhea and dysentery, and treats women's leukorrhea with red and white discharge and erosive ulcers of the yin organs. (Stir-fried with salt water.)
Huangbai has a cold qi, inheriting the freezing water energy of winter, entering the Foot-Shaoyin Kidney Meridian. Its taste is bitter and non-toxic, deriving from the fire flavor of the southern earth, entering the Hand-Shaoyin Heart Meridian.
Both its qi and taste are descending, belonging to Yin. Among the five viscera and six fu organs, the Heart is the monarch. The Heart belongs to Fire; accumulated heat is the stagnation of fire energy. Bitter taste drains heat, thus treating this condition. Jaundice is a syndrome of damp-heat in the Stomach Meridian. Intestinal hemorrhoids are a disease of fire stagnation in the Large Intestine. Diarrhea and dysentery are syndromes of damp-heat in the Large Intestine. Huangbai treats these because it enters the Kidney Meridian. The Kidney is the gate of the Stomach, and the Large Intestine is governed by the Kidney. Cold qi can clear heat, and bitter taste can dry dampness, thus treating the aforementioned syndromes. Leukorrhea with red and white discharge includes fetal leakage of blood and red/white vaginal discharge. One cause is reckless flow due to blood heat; another is downward pouring of damp-heat. Huangbai enters the Kidney; cold nature clears heat, and bitter nature dries dampness, thus treating this condition. Yin-yang erosive ulcers refer to erosive sores formed in the vulva. All sores belong to Heart Fire; Huangbai treats them because its bitter-cold nature drains fire.
Prescription Methods:
Huangbai combined with Zhimu (Anemarrhenae Rhizoma) nourishes Yin and descends fire; combined with Maoyu (Atractylodis Rhizoma) dispels dampness and clears heat, serving as a key herb for treating flaccidity syndrome; combined with Xixin (Asari Radix et Rhizoma) drains Bladder Fire, prepared by honey-frying and grinding into powder.
Wei Dasuan Wan (Baked Garlic Pills) treat white dysentery during pregnancy; combined with Mugua (Chaenomelis Fructus), Baifu Ling (Poria), Er Zhu (Atractylodis Rhizoma and Atractylodis Macrocephalae Rhizoma), Shihu (Dendrobii Caulis), and Shengdi (Rehmanniae Radix) treat flaccidity syndrome; combined with Baishao (Paeoniae Radix Alba) and Gancao (Glycyrrhizae Radix et Rhizoma) treat abdominal pain caused by fire-heat.
