一名黄花地丁
泻热，解毒
甘平。花黄，属土，入太阴、阳明（脾、胃）。化热毒，解食毒，消肿核。
专治乳痈（乳头属厥阴，乳房属阳明。同忍冬煎，入少酒服，捣敷亦良）疔毒，亦为通
淋妙品（诸家不言治淋，试之甚验）。擦牙、乌髭发（瑞竹堂有还少丹，方取其通肾。东垣
曰∶苦寒肾经君药），白汁涂恶刺（凡螳螂诸虫，盛夏孕育，游诸物上，必遗精汁，干久则
有毒。人手触之成疾，名狐尿刺。惨痛不眠，百疗难效，取汁浓涂即愈，千金方极言其功）。
叶如莴苣，花如单瓣菊花，四时有花，花罢飞絮，断之茎中有白汁（郑方升曰∶一茎两
花，高尺许者，掘下数尺，根大如拳，旁有人形拱抱。捣汁酒服，治噎膈如神）。
泻除热邪，解除毒害。
味甘性寒，归入肺经。疏散热邪，解除毒害（清热即是解毒），补益虚损（凡味道甘甜的药材都具有补益作用），治疗风邪，养血生津止渴（朱丹溪说：痈疽痊愈后出现口渴症状，用黄耆六一汤送服忍冬丸最为恰当。忍冬能养血，黄耆能补气，口渴自然消除）。
治疗痈疽、疥癣、杨梅疮等恶疮，以及肠风下血、痢疾，还有五种尸疰病。
金银花经冬不凋谢，所以名叫忍冬（又名左缠藤）。它的花和叶功效相同，花香尤其宜人，可以酿酒或代替茶饮。熬制成膏剂也非常好（忍冬酒，用于治疗痈疽发背等各种恶毒病症，在初起时服用效果奇特显著。干燥的药材也可以使用，只是不如新鲜药材见效快。取忍冬五两，甘草二两，加水两碗，煎至一碗，再加入酒一碗稍加煎煮，分三次服用，一天一夜内喝完。病情重的每天服用两剂，直到大小便通畅，说明药力已经到达病所。忍冬丸，按照前面的分量，用酒煮后晒干，与甘草一起研成粉末，用煮剩下的酒调糊做成丸剂。陈藏器说：对于热毒引起的血痢，浓煎服用。研成粉末，用糖调和经常服用，能使痘疹稀疏易出）。
蒲公英又名黄花地丁。
泻除热邪，解除毒害。
味甘性平。花朵呈黄色，五行属土，归入太阴、阳明经（脾经、胃经）。化解热毒，解除食物中毒，消散肿结核块。
专门治疗乳痈（乳头归属于厥阴经，乳房归属于阳明经。与忍冬同煎，加入少量酒服用，捣碎外敷也很好）；也治疗疔毒，同时也是通利小便的妙品（各家医书没有记载它能治疗淋证，但实际试用非常有效）。擦拭牙齿，使头发变黑（瑞竹堂有还少丹，方中取其通达肾气的作用。李东垣说：苦寒之品是肾经的主药）；用白色汁液涂抹被恶刺伤害处（凡是螳螂等昆虫，在盛夏孕育期间，爬过各种物体，必定留下精汁，干燥久了就有毒性。人手接触后会致病，名叫狐尿刺。疼痛剧烈无法入睡，各种疗法都难见效，取汁液浓涂即可痊愈，《千金方》极力称赞其功效）。
叶子像莴苣，花像单瓣菊花，四季都有花，花谢后飞絮，折断茎部有白色汁液（郑方升说：一株开两朵花，高一尺左右的，挖掘地下数尺，根部大如拳头，旁边有人形拱抱状。捣碎汁液用酒送服，治疗噎膈症神奇有效）。
To drain heat and detoxify.
Sweet and cold, enters the Lung Meridian. Disperses heat and detoxifies (clearing heat is equivalent to detoxifying), tonifies deficiency (all sweet substances have a tonifying effect), treats wind-pathogens, nourishes blood and relieves thirst (Zhu Danxi said: "For thirst occurring after the resolution of carbuncles and sores, taking Renshen Wan with Huangqi Liuyi Tang is most appropriate. Renshen nourishes blood, Huangqi tonifies Qi, so how can thirst arise?").
Treats carbuncles and sores, scabies and tinea, ymei chuang (chancre-like ulcers), bloody dysentery from intestinal wind, and five types of Shizhu diseases.
It does not wither in winter, hence named Rendong (also known as Zuochan Teng). The flowers and leaves have the same efficacy; its fragrance is particularly fine, and it can be used for brewing wine or making tea. Making an extract is also excellent (Rendong Wine: treats all kinds of malignant toxins such as carbuncles and back-sores; taking it at the initial stage yields miraculous effects. Dried herbs can also be used, though they are not as rapid in action as fresh ones. Take 5 liang of Rendong and 2 liang of Gancao, add 2 bowls of water, decoct until 1 bowl remains, then add 1 bowl of wine and simmer briefly. Divide into three doses, consumed within one day and night. For severe cases, administer two doses per day until bowel movements become smooth, indicating the medicinal power has reached the target. Rendong Wan: according to the previous proportions, boil in wine, dry, grind together with Gancao into powder, and form pills using the residual wine as a binder. Chen Cangqi stated: "For bloody dysentery caused by heat-toxin, decoct strongly and take. Grind into powder, mix with sugar, and take regularly to make rashes sparse and easy to erupt").
Also known as Huanghua Diding.
To drain heat and detoxify.
Sweet and neutral. The flower is yellow, corresponding to Earth, entering the Taiyin and Yangming meridians (Spleen and Stomach). Resolves heat-toxins, antidotes food poisoning, reduces swelling and dissipates nodules.
Specifically treats Ruphong (breast abscess) (the nipple belongs to the Jueyin meridian, the breast belongs to the Yangming meridian. Decoct together with Rendong, take with a little wine; applying the mashed herb externally is also good); also treats Dingdu (carbuncle toxin), and is a superb agent for promoting urination (most texts do not mention its use for Lin syndrome, but clinical trials prove it very effective). Rubbing teeth and darkening hair (Ruizhutang's Huanliao Dan uses this property to unblock Kidney Qi. Li Dongyuan said: "Bitter-cold herbs are the sovereign drugs for the Kidney meridian"); applying the white sap to treat "fox urine thorns" (any insect like the mantis, during summer reproduction, crawling over objects, leaves behind seminal fluid which becomes toxic when dried long-term. Human contact causes disease called "fox urine thorn," characterized by excruciating pain preventing sleep, resistant to many treatments. Applying concentrated sap cures it instantly; Qianjin Fang highly praises its efficacy).
Leaves resemble lettuce, flowers resemble single-petal chrysanthemums, flowering throughout the four seasons, producing fluff after blooming. Breaking the stem reveals white sap (Zheng Fangsheng said: "One stem bearing two flowers, about one chi high, digging several chi underground reveals roots as large as fists, with human-shaped arching formations beside them. Grinding the juice and taking it with wine miraculously treats Yige [dysphagia/esophageal obstruction]").
