白药
味辛，性温，无毒。主治金疮（金属利器造成的创伤）生肌。产于原州。
《唐本草》注解说：三月苗芽生出，叶子像苦苣菜，四月抽出红色的茎，花白色，根皮黄色，八月叶子落下，九月枝条折断，采集根部，晒干。现在参考其他版本的注释说：能解野葛、生金、巴豆的药毒，以及刀斧造成的折伤，能够止血、止痛，研成干末外敷。（此条附于《唐本草》之后）臣禹锡等人谨慎按《药性论》记载：白药也可以单用，味苦。能治疗喉中热塞感，噎痹不通，胸中狭隘堵塞，咽中经常疼痛，肿胀。日华子说：白药，性冷。能消痰止咳，治疗口渴和吐血，喉闭，消肿毒。又说翦草，性凉，无毒。治疗恶疮疥癣风瘙。根部名为白药。
《图经本草》说：白药，产于原州，现在夔州、施州、江西、岭南也有出产。三月生苗，叶子像苦苣叶，四月变红，茎长像葫芦蔓，六月开白花。八月结子，也叫做蒌。九月采根，用水洗，切碎，晒干，名为白药子。江西出产的，叶子像乌臼，子像绿豆，到了八月，其子变成赤色，施州人取根，并配野猪尾两味药，洗净去掉粗皮，焙干，等分，捣碎过筛，用酒调服钱匕量。治疗心气痛，解热毒，非常有效。又有各种疮痈肿不散的，取生根烂捣敷贴，干了就换。没有生药的用粉末水调涂也可以。崔元亮《海上方》：治疗一切天行（流行性传染病）。取白药研成粉状，浆水一大盏，空腹顿服，然后仰卧一顿饭的时间。等到心头闷乱，或者恶心，腹内如车鸣疠刺痛，很久之后应当有吐利数行，不要奇怪。想要服药时，先煮浆水粥在井中悬着待冷。如果吐利过度，就吃一碗冷粥止住它，不吃就会使人困倦。
经验后方：治疗妊娠伤寒，护胎。以白药子不拘多少为末，用鸡蛋清调摊在纸花上，大约碗来大，贴在脐下胎存生处，随即用温水润湿。
《衍义》说：白药，现在作为治疗马肺热的药，有效。
Baiyao (White Herb)
Pungent in flavor, warm in nature, non-toxic. Primarily treats metal wounds (injuries caused by metal weapons) and promotes tissue regeneration. Produced in Yuanzhou.
The *Tang Bencao* annotation states: In the third month, seedlings emerge; leaves resemble those of *Lactuca serriola*; in the fourth month, red stems shoot up, flowers are white, root bark is yellow; leaves fall in the eighth month, and branches break in the ninth month. Roots are harvested and dried in the sun. Current examination of other editions' annotations states: It can resolve the toxicity of wild gecko (*Gelsemium elegans*), raw gold, and croton seeds, as well as injuries from knives and axes; it can stop bleeding and relieve pain. Applied externally as a dry powder. (This note was appended to the *Tang Bencao*). Minister Yuxi et al. carefully consulted *Yaoxing Lun*: Baiyao can also be used alone, with a bitter taste. It can treat heat obstruction in the throat, dysphagia and blockage, chest tightness and congestion, frequent pain in the pharynx, and swelling. Rihua Zi stated: Baiyao is cold in nature. It resolves phlegm and stops coughing, treats thirst and hematemesis, throat closure, and reduces swelling and toxins. He also mentioned Jiancao (Cutting Grass), which is cool and non-toxic. It treats malignant sores, scabies, tinea, and wind-induced pruritus. The root is named Baiyao.
*Tujing* states: Baiyao is produced in Yuanzhou; it is now also found in Kuizhou, Shizhou, Jiangxi, and Lingnan. Seedlings emerge in the third month, leaves resembling those of *Lactuca serriola*, turning red in the fourth month. Stems grow long like gourd vines, and white flowers bloom in the sixth month. Seeds form in the eighth month, also known as Lou. Roots are harvested in the ninth month, washed with water, chopped, and sun-dried, named Baiyaozi. Those produced in Jiangxi have leaves resembling *Cornus kousa*, and seeds like mung beans; by August, the seeds turn red. People in Shizhou harvest the roots and combine them with pig tail (*Sus scrofa domesticus cauda*) in equal parts. After washing and removing the coarse skin, they are baked dry, ground, and sieved. Taken orally with wine in an amount equivalent to a coin pouch. It treats heart qi pain and resolves heat toxins, being very effective. For various sores and carbuncles that do not dissipate, fresh roots are mashed and applied topically; changed when dry. If fresh roots are unavailable, powdered form mixed with water for topical application is also acceptable. Cui Yuanliang's *Haishang Fang*: Treats all types of epidemic febrile diseases (infectious diseases spreading through the population). Take Baiyao, grind into flour-like powder, mix with one large cup of fermented grain water, take on an empty stomach in one dose, then lie supine for the duration of a meal. Wait until there is mental restlessness or nausea, and abdominal pain resembling chariot wheels rumbling or severe stabbing pain. After a while, several episodes of vomiting and diarrhea should occur; do not be alarmed. Before taking the medicine, boil fermented grain water congee and suspend it in a well to cool. If vomiting and diarrhea are excessive, eat one bowl of cold congee to stop them; otherwise, it will cause debility.
Empirical Later Formulas: Treats pregnancy complicated by cold damage (Shanghan), protecting the fetus. Take an unspecified amount of Baiyaozi, grind into powder, mix with egg white, spread onto paper flower shapes approximately the size of a bowl, apply to the lower abdomen where the fetus resides, and moisten with warm water immediately.
*Yanyi* states: Baiyao is currently used as a medicine for treating lung heat in horses, and it is effective.
