蒲公英，又名耩耨草。就是黄花地丁。长江南北地区很多，其他地方也有。岭南地区绝对没有。植株低矮贴地生长，茎叶四处散开。
茎和叶子像苦苣菜，带有细小的刺，折断后有白色汁液流出。四季都开黄花，比单瓣菊花大一些。花谢后飞絮中有种子，落地生根长出幼苗。
味道甘甜略带苦涩，药性平和偏寒。归入足阳明胃经，同时也归入足厥阴肝经和足少阴肾经。能化解各种热毒，消除恶肿、结核、疔疮等肿块。治疗妇女乳痈（乳腺炎），用来擦牙可以使头发变黑，强壮筋骨，解除食物中毒，疏散郁滞之气。这种草属土，吸收了水的冲和之气，应当是入肝、入胃，具有解热凉血功效的重要药物。妇女月经结束后，由肝经主事，所以它能主治乳痈肿毒。并且适宜生吃。（仲淳）
同贝母一起使用有“还少丹”，极力称赞此草的功效，认为它取法于能通补肾气。所以李东垣称其为足少阴肾经的本经君药。（传说越王遇到异人得到这个方子）极能坚固牙齿，强壮筋骨，滋生肾水。凡是年龄不到八十岁的人，服用它能使须发重新变黑，脱落的牙齿再生。用香附末五钱，腌制一夜，分成二十团，用三四层皮纸包裹扎紧，用六一泥密封加固，放入灶内焙干，然后用武火烤至通红为度，冷却后取出，去掉泥土研成粉末，早晚用来擦牙漱口，吐或咽下随意，时间久了才见效。
【论述】蒲公英味道甘甜而略带苦味，属于甘平而兼有微寒性质的药物。缪氏认为甘平的药剂，能够补益肝肾。
大青，到处都有。春天生出青紫色的茎，长二三尺高，节间对生叶片，长三四寸，叶面青色背面淡色，开花像蓼花，也像芫花。
味道甘甜略带苦涩和咸味，药性大寒。能解除心胃的热毒，主治时行热毒引起的头痛，身体忽冷忽热，以及热毒痢疾，治疗热毒引起的斑疹。
【论述】大青药性寒，味道甘甜略带苦涩和咸味。李时珍亲自尝试过，没有谬误。大概大热的病气，不用寒凉药无法去除。它能解除……（原文此处有残缺，推测意为解除热邪）。
Dandelion, also known as Jiangnou Grass. It is the Yellow Flower Diding (Taraxacum). It is abundant in the regions north and south of the Yangtze River, present in other places, but absolutely absent in Lingnan. The plant grows low to the ground, with stems and leaves spreading in all directions.
The stems and leaves resemble *Sonchus oleraceus* (Kuju), possessing fine thorns; when broken, they exude a white juice. It blooms yellow flowers throughout the four seasons, which are larger than single-petal chrysanthemums. After flowering, seeds are dispersed via pappus; upon landing, they sprout into seedlings.
The taste is sweet with a slight bitterness, and the nature is neutral and cold. It enters the Foot-Yangming Stomach Meridian, and also the Foot-Jueyin Liver Meridian and Foot-Shaoyin Kidney Meridian. It resolves all kinds of heat-toxins, eliminates malignant swellings, tubercles, and carbuncles. It treats breast abscesses (Ru Yong) in women, can be used to rub teeth to darken hair, strengthens sinews and bones, resolves food poisoning, and disperses stagnant Qi. This herb belongs to Earth and absorbs the harmonious Qi of Water; it should be considered an essential herb for entering the Liver and Stomach to clear heat and cool blood. After menstruation in women, the Liver Meridian takes charge; therefore, it primarily treats breast abscesses and toxic swellings. It is suitable for raw consumption. (Zhong Chun)
Combined with Fritillaria (Beimu), there is the Huan Shao Dan (Return to Youth Pill), which highly praises the efficacy of this herb, attributing its action to the ability to unblock the Kidney. Therefore, Li Dongyuan regarded it as the Sovereign Herb of the Foot-Shaoyin Kidney Meridian. (Legend has it that King Yue obtained this prescription from an immortal.) It strongly consolidates teeth, strengthens sinews and bones, generates Kidney Water. For anyone under eighty years old, taking it will cause hair and beard to turn black again, and fallen teeth to regrow. Take five qian of Cyperi Rhizoma powder, marinate overnight, divide into twenty balls, wrap tightly in three or four layers of skin paper, seal firmly with Liu Yi Ni (Six-One Mud), bake in a kiln until dry, then roast over strong fire until red-hot. Allow to cool, remove the mud, grind into powder, and use morning and evening to rub teeth and rinse mouth; spitting or swallowing is optional. Efficacy appears after long-term use.
[Discussion] Dandelion tastes sweet with a slight residual bitterness, belonging to the category of neutral and slightly cold agents. Miao believed that neutral agents can tonify the Liver and Kidney.
Da Qing (Isatidis Folium) is found everywhere. In spring, it produces greenish-purple stems, two or three chi high, with opposite leaves measuring three to four cun in length. The leaf surface is green, and the back is pale. The flowers resemble those of *Polygonum* (Tiaocao) or *Corydalis bungeana* (Yancao).
The taste is sweet with slight bitterness and saltiness, and the nature is greatly cold. It can resolve Heart and Stomach heat-toxins, primarily treating epidemic heat-toxin headaches, alternating chills and fever, heat-toxin dysentery, and treating heat-toxin-induced macules/rashes.
[Discussion] Da Qing has a cold nature and a sweet taste with slight bitterness and saltiness. Li Shizhen personally tasted it and confirmed its accuracy. Generally, extreme heat pathogens cannot be removed without cold herbs. It can resolve... [text fragment].
[Preparation] For conditions requiring Da Qing, if unavailable, replace it with Isatis Leaf (Da Lan Ye) or genuine Indigo Naturalis (Qing Dai).
