时珍曰∶五辛菜，乃元旦立春，以葱、蒜、韭、蓼、蒿、芥辛嫩之菜，杂和食之，取迎
新之义，谓之五辛盘，杜甫诗所谓∶“春日春盘细生菜”是矣。
【气味】辛，温，无毒。
藏器曰∶热病后食，多损目。
【主治】岁朝食之，助发五脏气。常食，温中去恶气，消食下气（藏器）。

时珍曰∶此菜易起苔，须采其苔食，则分枝必多，故名芸苔，而淮人谓之苔芥，即今油
菜，为其子可榨油也。羌陇氐胡，其地苦寒，冬月多种此菜，能历霜雪，种自胡来，故服虔
《通俗文》谓之胡菜，而胡洽居士《百病方》谓之寒菜，皆取此义也。或云塞外有地名云台
戍，始种此菜，故名，亦通。

恭曰∶《别录》云∶芸苔乃人间所啖菜也。
宗 曰∶芸苔不甚香，经冬根不死，辟蠹，于诸菜中亦不甚佳。

【集解】
李时珍说：五辛菜，是指在元旦和立春时，将葱、蒜、韭菜、蓼草、蒿草、芥菜这些辛辣嫩蔬混合食用，以取迎新之意，称为“五辛盘”，杜甫诗中所谓“春日春盘细生菜”指的就是这个。
【气味】
味辛，性温，无毒。
陈藏器说：热病痊愈后食用，会多伤眼睛。
【主治】
每年岁首早晨食用，能助发五脏之气。经常食用，能温暖中焦、祛除恶气、消食下气（陈藏器）。
（出自《唐本草》）
【释名】
寒菜（胡居士方）、胡菜（同上）、苔菜（《埤雅》）、苔芥（《沛志》）、油菜（《纲目》）。
李时珍说：这种菜容易长出苔茎，必须采摘其苔茎食用，这样分枝就会增多，所以名叫芸苔，而淮地人称之为苔芥，即现在的油菜，因为它的种子可以榨油。羌陇氐胡地区，气候苦寒，冬季多种植这种菜，它能经受霜雪，种子是从胡地传来的，所以服虔在《通俗文》中称它为胡菜，而胡洽居士在《百病方》中称它为寒菜，都是取这个意思。有人说塞外有个地名云台戍，开始种植这种菜，所以得名，这也讲得通。
【集解】
苏恭说：《名医别录》记载：芸苔是民间所食用的蔬菜。
苏颂说：芸苔香气不浓，经过冬天根部不死，能防虫蛀，在众多蔬菜中也不算特别优良。
李时珍说：芸苔在方药中应用广泛，各家注解也不明确，现在人不认识这是什么菜？我经过访查考证，就是现在的油菜。九月、十月播种，长出的叶子形状颜色略像白菜。冬、春季节采摘苔心作为蔬菜食用，到了三月就老了不可食用。开小黄花，四瓣，像芥菜花。结荚收子，也像芥子，呈灰赤色。炒过后榨出的油是黄色的，点灯很明亮，食用则不如麻油。近来人们因为有利可图，种植的人也很多了。
茎叶
【气味】
味辛，性温，无毒。孟诜说：性凉。
《名医别录》说：春季食用，能诱发膝部的陈旧性疾病。
孟诜说：先前患有腰脚病的人，不可多吃，吃了会加重病情。又损伤阳气，引发疮疡及口齿疾病。有狐臭的人不可食用。又能生腹中各种寄生虫。道家特别忌讳，将其列为五荤之一。
【主治】
治疗风游丹肿、乳痈（《唐本草》）。破除症瘕结血（《开宝本草》）。治疗产后血风及瘀血（《日华子本草》）。
煮食，治疗腰脚痹痛。捣烂叶片，外敷治疗妇女吹奶（陈藏器）。治疗瘭疽、豌豆疮，散血消肿。伏蓬砂（李时珍注）。
【发明】
陈藏器说：芸苔能破血，所以产妇适宜食用。
马志说：如今俗话常说病人能吃芸苔，说明是有血病。
孙思邈说：贞观七年三月，我在内江县饮酒过多，到夜里觉得四肢骨肉疼痛。天亮时头痛，额角出现红色斑块如弹丸大小，肿痛。到中午全身肿胀，眼睛无法睁开。过了一天几乎丧命。我想起《本草》记载芸苔治疗风游丹肿，于是取叶片捣烂外敷，随手即消，其效如神。也可以捣汁服用。
【附方】新收录七方。
赤火丹毒：方剂见上文。
天火热疮，初起似痱子，逐渐变成水泡，像火烧的疮，红色，发展迅速能致死：用芸苔叶捣汁，调和大黄、芒硝、生铁衣等份，涂抹患处。（《近效方》）。

异疽似痈，但略有不同，脓液如小豆汁，今天去除，明天又满：用芸苔捣熟，用湿布袋盛装，在热灰中煨熟，交替熨烫患处，不超过三、两次。没有叶子就用干的。（《千金方》）。

【发明】
李时珍说：芸苔的菜子和叶子功效相同。其味辛气温，既能温补又能发散。其特长在于行血滞、破结气。所以古方中用于消肿散结、治疗产后一切心腹气血痛、各种游风丹毒热肿疮痔的药物都常用它。月经结束后，加入四物汤服用，据说能避孕。又用于治疗小儿惊风，贴敷头顶囟门，能引气上出。《妇人方》治疗难产的歌诀说：“黄金花结粟米实，细研酒下十五粒。灵丹功效妙如神，难产之时能救急。”

(From *Bencao Shiyi* [Supplement to Materia Medica])
[Ji Jie] (Collected Explanations)
Li Shizhen said: "Wuxin Cai" (Five Pungent Vegetables) refers to the practice on New Year's Day and Lichun (Start of Spring) of mixing pungent tender vegetables such as scallion, garlic, Chinese chive, smartweed, mugwort, and mustard greens for consumption. This is done to welcome the new year and is called the "Wuxin Pan" (Five Pungent Plate). This is what Du Fu referred to in his poem as "fine raw vegetables in the spring day plate."
[Qi Wei] (Flavor and Properties)
Pungent, warm, non-toxic.
Chen Cangqi said: Consuming this after a febrile disease will damage the eyes.
[Zhu Zhi] (Therapeutic Actions)
Consuming it on the morning of the New Year aids the qi of the five zang organs. Regular consumption warms the middle jiao, eliminates foul qi, promotes digestion, and directs qi downward (Chen Cangqi).
(From *Tang Bencao* [Tang Materia Medica])
[Shi Ming] (Names)
Han Cai (Cold Vegetable) (Hu Jushi Fang), Hu Cai (Barbarian Vegetable) (ibid.), Tai Cai (Moss Vegetable) (*Pi Ya*), Tai Jie (Moss Mustard) (*Pei Zhi*), You Cai (Oil Vegetable) (*Gangmu*).
Li Shizhen said: This vegetable easily produces flowering stalks ("tai"). If the stalks are harvested for eating, the plant branches more, hence the name Yuntao. People in Huai call it Tai Jie, which is today's rapeseed (You Cai), because its seeds can be pressed for oil. In the Qiang, Long, Di, and Hu regions, where the climate is bitterly cold, this vegetable is widely planted in winter as it can withstand frost and snow. The seeds originated from the Hu lands, so Fu Qian in *Tongsu Wen* called it Hu Cai, and Hu Qia Jushi in *Baibing Fang* called it Han Cai, both reflecting this meaning. Alternatively, some say it was first planted at a place called Yuntai Shu beyond the frontier, hence the name; this explanation is also plausible.
[Ji Jie] (Collected Explanations)
Su Gong said: *Bielu* states that Yuntao is a vegetable eaten by common people.
Su Song said: Yuntao has little fragrance; its roots survive the winter; it repels insects; among various vegetables, it is not considered particularly excellent.
Li Shizhen said: Yuntao is used frequently in prescriptions, yet previous annotations were unclear, and modern people do not recognize what vegetable it is. After investigation and verification, I found it to be the current rapeseed (You Cai). Sown in September or October, the leaves resemble cabbage slightly in shape and color. The heart of the flowering stalk is harvested as a vegetable in winter and spring but becomes too tough to eat by March. It bears small yellow flowers with four petals, resembling mustard flowers. It forms pods containing seeds like mustard seeds, grayish-red in color. Pressed after roasting, the oil is yellow, burns brightly in lamps, but is inferior to sesame oil for eating. Recently, due to its profitability, cultivation has become widespread.
Stems and Leaves
[Qi Wei] (Flavor and Properties)
Pungent, warm, non-toxic. Meng Shen said: Cool.
*Bielu* stated: Consuming it in spring can trigger chronic knee diseases.
Meng Shen said: Those with prior waist and leg ailments should not consume it excessively, as it exacerbates the condition. It damages yang qi, induces sores, and causes oral and dental diseases. People with body odor should avoid it. It can also generate various parasites in the abdomen. Daoists specifically prohibit it, classifying it as one of the Five Pungent Herbs.
[Zhu Zhi] (Therapeutic Actions)
Treats migratory wind erysipelas and swelling, mastitis (*Tang Bencao*). Breaks up masses and blood stasis (*Kaibao Bencao*). Treats postpartum wind-blood and blood stasis (*Rihua Bencao*).
Boiled and eaten, treats numbness and pain in the waist and legs. Crushed leaves applied externally treat "blowing milk" (breast engorgement/infection) in women (Chen Cangqi). Treats phagedenic ulcers and variola (smallpox/measles-like eruptions), disperses blood and reduces swelling. Fu Pengsha (Li Shizhen note).
[Fa Ming] (Elucidation)
Chen Cangqi said: Yuntao breaks blood stasis, so it is suitable for postpartum women.
Ma Zhi said: Common parlance suggests that if a patient can eat Yuntao, it indicates a blood disorder.
Sun Simiao said: In the third month of the 7th year of Zhenguan, after drinking heavily in Neijiang County, I felt pain in my limbs and bones that night. By dawn, I had a headache and red patches on my forehead like quail eggs, swollen and painful. By noon, my whole body swelled, and I could not open my eyes. I nearly died the next day. Recalling that *Bencao* records Yuntao for treating migratory wind erysipelas, I crushed the leaves and applied them externally. The swelling subsided immediately, proving miraculous. It can also be crushed for juice ingestion.
[Fu Fang] (Attached Prescriptions) Seven new formulas.
Chi Huo Dan Du (Red Fire Erysipelas): Formula seen above.
Tian Huo Re Chuang (Heavenly Fire Heat Sores): Initially resembling prickly heat, gradually becoming blisters like burn wounds, red in color, developing rapidly and potentially fatal: Crush Yuntao leaves for juice, mix with equal parts Rhubarb, Mirabilite, and Ferri Oxidatum (Sheng Tie Yi), and apply externally. (*Jin Xiao Fang*).
Feng Re Zhong Du (Wind-Heat Toxic Swelling): Three taels each of Yuntao seedling leaves/roots and Vitex root, powdered. Mix with egg white and apply; swelling dissipates immediately. If Vitex root is unavailable, Phytolacca root can be substituted with good effect. (*Jin Xiao Fang*).
Zu Shou Biao Ju (Hand/Foot Phagedenic Ulcer): This ulcer favors hands, feet, shoulders, and back, appearing like red beans, oozing fluid when peeled: Drink one sheng of decoction made from boiling Yuntao leaves, along with several meals of dry cooked vegetables with minimal salt and sauce. In winter, use seeds ground in water. (*Qian Jin Fang*).
Yi Ju Si Yong (Atypical Ulcer Resembling Carbuncle): Differs slightly from carbuncles; pus resembles mung bean juice; recurs daily: Cook crushed Yuntao thoroughly, wrap in a wet cloth bag, warm in hot ashes, and apply alternately to the site. No more than two or three applications. Dry leaves may be used if fresh ones are unavailable. (*Qian Jin*).
Wan Dou Ban Chuang (Pea-like Spots/Rash): Wash the affected area with a decoction of Yuntao leaves. (*Waitai Miyao*).
Xue Li Fu Tong (Bloody Dysentery with Abdominal Pain): Unceasing day and night: Two he of juice from crushed Yuntao leaves mixed with one he of honey, taken warm. (*Shenghui Fang*).
Chang Feng Xia Xue (Intestinal Wind Bleeding)
Seeds
[Qi Wei] (Flavor and Properties)
Pungent, warm, non-toxic.
[Zhu Zhi] (Therapeutic Actions)
Treats nocturnal emission and "ghost intercourse" (Sun Simiao). Applying the oil to the head promotes black, long hair growth (Chen Cangqi). Promotes blood circulation, dispels cold qi, reduces swelling, dissipates nodules, treats dystocia, postpartum abdominal disorders, red erysipelas with heat/swelling, traumatic injuries, and hemorrhoids (Li Shizhen).
[Fa Ming] (Elucidation)
Li Shizhen said: Rapeseed and leaves have identical functions. Their pungent-warm flavor allows for both warming and dispersing actions. They excel at moving blood stasis and breaking qi stagnation. Thus, ancient formulas for reducing swelling, dissipating nodules, treating postpartum abdominal qi/blood pain, and various wind-erysipelas/heat-swelling/sores/hemorrhoids commonly include them. Taken after menstruation with Siwu Tang, it is said to prevent conception. It is also used for pediatric convulsions; applying it to the anterior fontanelle draws qi upward. The *Funren Fang* song for dystocia says: "Golden flowers yield millet-like seeds, finely ground and taken with wine, fifteen pills. The spiritual pill works miraculously, saving lives during difficult labor."
[Fu Fang] (Attached Prescriptions) Twelve new formulas.
Yuntao San: Treats postpartum lochia retention with blood clumping striking the heart causing stabbing pain. Upon exposure to cold later, blood moves between heart and abdomen causing unbearable stabbing pain, termed "Blood Mother." Also treats various postpartum abdominal disorders. Essential within three days postpartum. Equal parts roasted Yuntao seeds, Angelica sinensis, Cinnamon twig, and Red Peony root. Take two qian with wine to expel evil matter. (*Yangshi Chanru*).
Chan Hou Xue Yun (Postpartum Blood Fainting): Equal parts Yuntao seeds and Rehmannia root. Powdered. Take three qian per dose with seven slices of ginger, half cup wine, half cup water, and half cup child's urine. Decoct to 0.7 portion, take warm to regain consciousness. (*Haishang Xianfang*).
Bu Xue Po Qi (Tonify Blood, Break Qi): Zhui Qi Wan: Treats uterine stabbing pain and unbearable lower abdominal pain. Can be taken regularly to tonify blood deficiency and break qi masses effectively. One liang each of lightly roasted Yuntao seeds and Cinnamon twig, half liang Galangal. Powdered, formed into pills the size of wutong seeds with vinegar paste. Take five pills with light vinegar soup. (*Lingyuan Fang*).
Chang Feng Zang Du Xia Xue (Intestinal Wind and Visceral Toxin Bleeding): Raw Yuntao seeds and roasted Licorice root, powdered. Take two qian, decoct in water. (*Shenghui Fang*).
Tou Feng Zuo Tong (Head Wind Pain): One part Yuntao seeds, three parts Rhubarb. Powdered, insufflate into nose.
Feng Re Ya Tong (Wind-Heat Toothache): Equal parts Yuntao seeds, White Mustard seeds, and Illicium anisatum. Powdered, insufflate into nose: left nostril for right pain, right nostril for left pain. (*Shenghui*).
Xiao Er Tian Gou (Pediatric Tetanus/Convulsion): Two qian each of Yuntao seeds and Aconitum carmichaelii (raw, peeled, tip removed). Powdered. Apply one qian mixed with water to the top of the head. Named Tuding San. (*Shengji Zonglu*).

Re Ji Zhong Du (Hot Boils and Toxic Swelling): Equal parts Yuntao seeds and dog skull bone. Powdered, mixed with vinegar for application. (*Qianjin Fang*).
Shang Sun Jie Gu (Trauma and Bone Setting): One liang Yuntao seeds, two he roasted foxtail millet, a little Dragon bone. Powdered, mixed with vinegar into a paste, spread on paper and applied. (*Qiankun Mi Yun*).
Tang Huo Shang Zhuo (Scalds and Burns): Rapeseed oil mixed with earthworm feces, applied externally. (*Jianbian Danfang*).
Wugong Shi Shang (Centipede Bite): Pour rapeseed oil on the ground, rub the oil from the ground onto the wound. Avoid letting "four-eyed people" see it. (*Jide Tang Fang*).
