（本经上品）
具高明之象，秉寒水之化令。
【气味】苦平，无毒。
【主治】主大热火疮，身热烦，邪恶气。花主女人漏下赤白，轻身，明目。
【核】曰∶景天，一名慎火、戒火，即火丹草也。出太山山谷，今南北皆有。种置檐屋，
云可辟火。春生苗，高一二尺，茎色黄赤，质极脆弱，折之有汁，叶色淡绿，似马齿苋，光
泽柔浓，作层而上。夏开碎花红白，结实如连翘而小，中有黑子如粟粒。秋后茎枯，明年宿
根再发。
【 】曰∶性喜高显，因名景天。置之檐屋，顺其性尔。炎上作苦，苦性走下，火热为
本者

久
【核】曰∶出汉中、金州、梁州者最善，益州、广州、浙中者次之。木高数丈，干如柿，
叶如椿，花如槐，实如牛柰子。五六月刻取汁液，干之即曰干漆，状如蜂房，孔孔间隔，但
性急易燥，热则难干，无风阴润，虽严寒亦易燥，否则不堪入药。修治，捣碎，炒熟，不尔
损人肠胃。半夏为之使。畏鸡卵，忌油脂。得蟹则化而成水。
【 】曰∶夏三月，漆液始足，当入心，以色朱明而性燥急，半夏为使可知矣。干之当
入肾，以色玄英而喜阴润，蟹化成水可知矣。入肾为肾之心药；入心为心之肾药。补中者，
补中焦血液，血液皆繇中焦变化所成也。心主血，肾主液故尔。则凡血液燥涸，致筋脉缓急
断伤，及髓脑不满，五脏不安，痹闭不通，罔不有功。而接续填满，奠安周痹，皆克成血液
之濡润流通者。生漆去长虫，以其入心，则得心君火大之令。如大火聚，长虫自无 类矣。
（水泻欲流之谓漆，即具水之体，火之用矣。）
【《神农本草经》上品】
具备高显光明的形象，禀受寒水的化生规律。
【气味】味苦，性平，无毒。
【主治】主治大热引起的火疮，身体发热烦躁，以及邪恶之气（指不正的邪气）。其花主治妇女赤白带下漏下，使人身体轻健，目光明亮。
【核析】曰：景天，又名慎火、戒火，也就是火丹草。产于泰山山谷中，如今南北各地都有种植。人们将其种在屋檐或屋顶上，据说可以辟除火灾。春天生出苗茎，高一二尺，茎色黄赤，质地非常脆弱，折断后有汁液流出；叶色淡绿，形状像马齿苋，光泽柔和浓密，层层向上生长。夏天开出细碎的红白花，结出的果实像连翘但较小，里面有黑色的种子如粟粒大小。秋后茎叶枯萎，明年宿根再次发芽生长。
【《神农本草经》上品】
【气味】味辛，性温，无毒。
【主治】主治严重的外伤断折，补益中焦，接续筋骨，填补髓脑，安定五脏，治疗五缓六急证，以及风寒湿痹。生漆能去除体内的长虫（寄生虫）。
【核析】曰：出产于汉中、金州、梁州的品质最好，出产于益州、广州、浙中的品质次之。树木高达数丈，树干像柿子树，叶子像椿树，花像槐树，果实像牛柰子。在五六月间刻取树液，干燥后即成为干漆，形状像蜂房，孔孔间隔。但干漆性质急躁容易燥裂，天气热时难以干燥，若无风且阴湿，即使在严寒中也容易燥裂，否则不堪入药。炮制方法是捣碎，炒熟，否则损伤人的肠胃。半夏是它的引经药（使药）。害怕鸡蛋，忌食油脂。遇到螃蟹就会化成水。
【核析】曰：夏季三个月，漆液才充足，此时入心，因为颜色朱红明亮而性质燥急，可知以半夏为使药。干燥后当入肾，因为颜色黑而有英华且喜欢阴润，可知遇蟹化为水。入肾则成为肾的心药；入心则成为心的肾药。所谓“补中”，是补益中焦的血液，因为血液都是由中焦变化所生成的。心主血，肾主液，所以如此。那么凡是血液干燥枯竭，导致筋脉缓急、断伤，以及髓脑不满、五脏不安、痹闭不通的情况，没有不发挥功效的。而接续填满、安定周身痹痛，都是依靠血液的濡润流通来完成的。生漆去除长虫，是因为它入心，从而获得心君之火的大令。就像大火聚集一样，长虫自然无法生存了。（流动如水泻欲流的状态称为漆，即具备了水的形体和火的作用。）
(Shennong Bencao Jing, Upper Grade)
Possesses the image of height and brightness, and inherits the transformational decree of Cold Water.
[Flavor and Nature] Bitter, neutral, non-toxic.
[Indications] Primarily treats severe heat-induced fire sores, fever with restlessness, and evil qi (referring to pathogenic factors). The flowers primarily treat leukorrhea (vaginal discharge) in women, lighten the body, and brighten the eyes.
[Analysis] It is said: Jing Tian (Sedum aizoon), also known as Shen Huo (Caution Fire) or Jie Huo (Avoid Fire), is the same as Huo Dan Cao (Fire Erysipelas Herb). It grows in the valleys of Mount Tai and is now cultivated in both northern and southern regions. It is planted on eaves and roofs, it is said to ward off fire. In spring, shoots emerge, one to two chi high; the stems are yellowish-red, extremely fragile, exuding juice when broken; the leaves are pale green, resembling Portulaca oleracea (Ma Chi Xian), glossy, soft, dense, and growing in layers upwards. In summer, small red and white flowers bloom, bearing fruits similar to Forsythia suspensa (Lian Qiao) but smaller, containing black seeds like millet grains. After autumn, the stems wither, and next year the perennial roots sprout again.
(Shennong Bencao Jing, Upper Grade)
[Flavor and Nature] Pungent, warm, non-toxic.
[Indications] Primarily treats severe traumatic injuries, tonifies the middle jiao, reconnects sinews and bones, fills the marrow and brain, calms the five zang organs, treats wu huan liu ji syndrome (five slacknesses and six tensions), and wind-cold-damp bi obstruction. Raw Qi (lacquer) eliminates long worms (parasites).
[Analysis] It is said: Those produced in Hanzhong, Jinzhou, and Liangzhou are of the best quality; those from Yizhou, Guangzhou, and Zhejiang are secondary. The tree grows several zhang high, the trunk resembles Diospyros kaki (Persimmon), leaves resemble Toona sinensis (Chun), flowers resemble Sophora japonica (Huai), and fruits resemble Naematolocus dodecandrus (Niu Nai Zi). In the fifth and sixth lunar months, the sap is tapped and dried to become Gan Qi (Dried Lacquer), which looks like a honeycomb with porous intervals. However, its nature is urgent and prone to drying/cracking; in hot weather, it is difficult to dry; without wind and in humid conditions, it cracks easily even in severe cold; otherwise, it is unsuitable for medicinal use. Processing involves crushing and stir-frying until cooked; otherwise, it damages the stomach and intestines. Ban Xia (Pinelliae Rhizoma) serves as its guiding herb (shi). It fears chicken eggs and avoids grease. When combined with crab, it transforms into water.
[Analysis] It is said: During the three months of summer, the lacquer sap is sufficient, entering the Heart, because its color is vermilion and bright, and its nature is dry and urgent; thus, Ban Xia is used as the guiding herb. After drying, it enters the Kidney, because its color is dark/black with luster and it prefers yin and moisture; thus, it transforms into water when meeting crab. Entering the Kidney, it becomes the Heart medicine for the Kidney; entering the Heart, it becomes the Kidney medicine for the Heart. "Tonifying the middle" refers to tonifying the blood of the middle jiao, as blood is formed through transformations in the middle jiao. The Heart governs blood, and the Kidney governs fluids, hence this. Therefore, in cases where blood is dry and depleted, leading to slackness or tension of sinews and vessels, traumatic injuries, insufficient marrow and brain, unrest of the five zang organs, and bi obstruction, it is effective. The reconnection, filling, and stabilization of generalized bi pain are all achieved through the moistening and free flow of blood. Raw Qi eliminates long worms because it enters the Heart, thereby obtaining the great command of the Heart Sovereign Fire. Like a gathering of great fire, long worms naturally perish. (The state of flowing like water leakage is called Qi, possessing the form of water and the function of fire.)
