这就是槐实（即槐角）。具有泻除风热、清肝火、凉大肠的功效。
味苦，性寒。能清肝胆之火，凉大肠之热，疏散风热。治疗心烦闷乱、因风邪引起的眩晕以及痔疮出血和肠风便血。（粪便前有血，称为外痔；粪便后有血，称为内痔；肛门处有肉赘脱出，称为举痔；肛门上有孔洞，称为痔漏；疮内有虫，称为虫痔；一般治法使用槐角、地榆、生地、人参来凉血生血，防风、秦艽来祛风湿，当归、川芎来调和血液，黄芩、枳壳来宽肠理气，升麻来升提阳气，治疗肠风的方剂大致相同，但不宜专门使用寒凉药物，必须兼用补益药剂以收功。）还能治疗阴部疮疡、潮湿瘙痒。明目去泪。（因为清肝火，而泪为肝热所致。）坚固牙齿，使胡须变黑。（槐树是虚星的精气所化，在农历十月上巳日采集，浸泡在牛胆中阴干一百天，饭后吞服一枚，白发可转黑，对于肠风便血尤其适宜服用。）还有杀虫和堕胎的作用。槐树的性质纯阴，体质虚寒者应当禁忌。即使是虚热而非实火，也不要随意投药。使用时需去掉单子和五子，用铜槌捶碎，用牛乳拌蒸。
槐花（具有泻热凉血的功效）。味苦，性凉。功效与槐实相同。能凉血，治疗风热引起的目赤肿痛，赤白痢疾，各种痔疮和肠风便血，吐血、崩漏、鼻衄等各种出血症状。（舌上出血如线状，称为舌衄，将槐花炒研后掺敷患处。）忌与槐实同用。含花蕊且陈久者为佳。微炒后用。
又名金铃子。具有泻湿热、治疗疝气、杀虫的功效。
味苦，性寒，有小毒。能引导小肠和膀胱的热邪下行，从而引心包相火下行，通利小便，是治疗疝气的要药。也能治疗伤寒引起的热狂、热厥腹痛，疗疮疥癣，杀灭三虫。（《夷坚志》记载：消渴证中，有虫子消耗津液的情况，取根皮浓煎，少加麝香服用，排出虫子后口渴自然停止。）味苦性寒，只适宜用于杀虫，脾胃虚寒者大忌。四川产的药材质量较好。用酒蒸至皮软。（这是寒药热用的方法。）刮去皮，取肉去核。凡是用药时只用肉不用核，或用核不用肉。如果使用核，需捶碎，以茴香为使药。槐花（铺在席子下，可以杀蚤虱，效果验证过。）
This is Huai Shi (Sophorae Fructus, i.e., Sophora japonica fruit). It drains wind-heat, clears the Liver, and cools the Large Intestine.
Bitter and cold in nature. It clears the Liver and Gallbladder, cools the Large Intestine, and disperses wind-heat. It treats irritability, dizziness caused by wind, hemorrhoidal bleeding, and Chang Feng (intestinal wind) with blood in stool. (Blood before defecation is called Wai Zhi [external hemorrhoids]; blood after defecation is called Nei Zhi [internal hemorrhoids]; flesh protruding from the anus is called Ju Zhi [prolapsed hemorrhoids]; a hole above the anus is called Zhi Lou [anal fistula]; parasites within the lesion are called Chong Zhi [parasitic hemorrhoids]. The general treatment method uses Huai Jiao (Sophorae Fructus), Di Yu (Sanguisorbae Radix), Sheng Di Huang (Rehmanniae Radix), and Ren Shen (Ginseng Radix et Rhizoma) to cool blood and generate blood; Fang Feng (Saposhnikoviae Radix) and Qin Jiao (Gentianae Macrophyllae Radix) to dispel wind-dampness; Dang Gui (Angelicae Sinensis Radix) and Xiong Duan (Ligustici Chuanxiong Rhizoma) to harmonize blood; Huang Qin (Scutellariae Radix) and Zhi Ke (Aurantii Fructus) to broaden the intestines; Sheng Ma (Cimicifugae Rhizoma) to raise yang. Formulas for treating Chang Feng are roughly similar, but one should not rely solely on cold-natured drugs; tonifying agents must be combined to achieve success.) It also treats yin sores, damp itching, brightens the eyes, and reduces tearing. (Clearing Liver heat reduces tearing, as tears are related to Liver heat.) It strengthens teeth and darkens beard hair. (Huai tree is the essence of the Void Star; collected on the Shang Si day in the tenth lunar month, soaked in ox gall, dried in shade for one hundred days, taken orally after meals, one pill at a time, turning white hair black again; it is especially suitable for Chang Feng and hemorrhoidal bleeding.) It has insecticidal and abortifacient properties. Huai tree nature is purely Yin; those with deficiency-cold should avoid it. Even if it is deficiency-heat rather than excess-fire, do not administer recklessly. Remove the single seed and five seeds, crush with a copper pestle, steam with cow's milk.
Huai Hua (Sophorae Flos) (drains heat and cools blood). Bitter and cool in nature. Its functions are the same as Huai Shi. It cools blood, treats red eyes due to wind-heat, dysentery with red and white discharge, various hemorrhoids, Chang Feng, hematemesis, metrorrhagia, epistaxis, and other bleeding conditions. (Bleeding from the tongue like a thread is called She Nu [lingual bleeding]; apply roasted and powdered Huai Hua topically.) Avoid using together with Huai Shi. Those containing stamens and aged for a long time are superior. Lightly stir-fry before use.
Also known as Jin Ling Zi (Evodiae Fructus). It drains damp-heat, treats hernia, and kills parasites.
Bitter, cold, and slightly toxic. It can guide heat from the Small Intestine and Bladder downward, thereby drawing down Ministerial Fire from the Pericardium, promoting urination, and serving as a key herb for treating hernia qi. It also treats mania due to heat in Shang Han (Cold Damage), abdominal pain due to heat-jue, carbuncles, scabies, and kills three types of parasites. (Yi Jian Zhi records: In cases of Xiao Ke [wasting-thirst syndrome] where parasites consume body fluids, decoct the root bark strongly, add a small amount of She Xiang (Moschus), ingest to expel parasites, and thirst will cease naturally.) Bitter and cold in nature, it is only suitable for killing parasites; those with Spleen-Stomach deficiency-cold strictly avoid it. Those produced in Sichuan are of good quality. Steam with wine until the skin is soft. (This is using cold medicine with heat application.) Scrape off the skin, take the flesh, remove the core. When using, use either the flesh or the core, not both. If using the core, crush it, and use Hui Xiang (Foeniculi Fructus) as a guiding drug. Huai Hua (spread under mats to kill fleas and lice, efficacy verified.)
