【芸苔（油菜）】
就是现在的油菜。在九月、十月播种长出叶子。冬春季节采摘菜苔的心部作为蔬菜食用。到了三月就变得老硬，不能食用了。开花结籽后，全部经过炒制榨油。燃烧灯盏时非常明亮。
茎叶
气味辛凉。治疗风邪引起的游走性丹毒肿胀。（人体突然变红，像丹砂的颜色一样，称为丹毒。有时发于手足，有时发于腹部如手掌大小，都是由于风热恶毒所致。）治疗腰脚痹痛，破除症瘕积聚的瘀血，治疗产后血风及瘀血，以及乳痈。将叶子捣碎吹入乳头内。（出自诸本草）丹毒即将发作时，初觉四肢骨肉疼痛，逐渐出现头痛，额角处出现如弹丸大小的红色斑块且疼痛，超过三天肿胀如同小豆汁一般，今天消退，明天又充满。用芸苔捣烂，用熟布袋盛装，在热灰中煨热，交替熨烫患处。不过两三次即可痊愈。如果没有叶子，可以用干品。
子
气味与茎叶相同。主治行滞血，破冷气，消肿散结。治疗难产。（细研十五粒，用酒送服。）以及产后心腹气块。贴敷使用。
〔论〕芸苔的功效，人们通常认为只是行滞血、散结气罢了。哪里知道它自种于冬季，经历霜雪，到春天抽苔。其味辛，入脏。首先主治游风丹肿，以及产后血风，并切于心腹各种疾病的原因，是因为风脏原本也是血脏，鼓动阳气以化生阴血，关键在于此。所以风气运行而血液得以化生，血液不化生就会反过来导致风邪淫溢。二者相互为用，也相互影响产生病变。这种药物的功能，不能因为它细微而忽视它。
孟诜说：先患有腰脚病的人，食用它会加剧病情。又会损伤阳气，多吃会引发疮疡及口齿疾病，又能生腹中各种寄生虫。
【杏仁】
五月采收。双仁的有毒，能杀人，不可使用。
气味甘苦温冷利。（性质滋润，利于下行，并非真正的寒冷。）有小毒。气薄味浓，浊而沉坠，具有降泄作用。入手太阴肺经。能治肺气喘促。杏仁下喘，是治疗气分的；桃仁疗狂，是治疗血分的。都治疗大病，不可过度泄泻。脉浮者属气分，用杏仁配陈皮；脉沉者属血分，用桃仁配陈皮。（肺与大肠相表里，贲门主管往来，魄门主管收闭，是气运行的通道，所以并用陈皮来辅助。）同天冬煎煮，润心肺。肺燥喘热，大肠便秘，用杏仁去皮研细，每一升加入水一升半，捣成稠汁，加入生姜四两，甘草一寸，放入银石器中，用慢火熬成稀膏，加入酥二两一同收存。每晚，用沸水冲服一匙。久患肺气喘急，咳嗽严重的，用杏仁去皮尖二两，用童便浸泡，一天换一次，夏季三四次换，满半个月取出，焙干研细。每次服用枣核大的一团，加薄荷一叶，蜂蜜如鸡蛋大，水一钟，煎至七分，食后温服。不超过两剂，永远痊愈。忌食腥物。风虚头痛欲裂者，用杏仁去皮尖，晒……此法神妙，可用……黛一钱，做成饼……用杏仁三升去……研匀点之。目……头点之。

[Youcai (Rapeseed)]
This is the current rapeseed. Sown in September and October to grow leaves. In winter and spring, the hearts of the flowering stems are harvested as vegetables. By March, they become tough and inedible. After flowering and seeding, all are stir-fried and pressed for oil. It burns very brightly in lamps.
Stems and Leaves
Pungent and cool in nature. Treats wind-induced wandering erysipelas swelling. (Human body suddenly turns red, resembling cinnabar, known as erysipelas or carbuncle. It may appear on hands and feet, or on the abdomen like the size of a hand, all caused by evil heat-toxin from wind.) Treats bi-syndrome (obstruction syndrome) of the waist and legs, breaks up masses and blood stasis, treats postpartum wind-blood syndrome and blood stasis, as well as breast abscess. Crush the leaves and blow them into the nipple. (From various Materia Medica texts). When erysipelas is about to erupt, initially feeling pain in the limbs and muscles/bones, gradually developing headache, with red patches like bean shots on the forehead corners that hurt. After more than three days, swelling resembles mung bean juice; it disappears today and fills tomorrow. Crush Youcai, place in a hot cloth bag, warm it in hot ashes, and apply alternating compresses. It will heal within two or three applications. If no fresh leaves are available, use dried ones.
Seeds
Nature and flavor are the same as stems and leaves. Mainly treats moving stagnant blood, disperses cold qi, reduces swelling and dissipates nodules. Treats difficult labor. (Grind fifteen seeds finely, take with wine.) Also treats postpartum heart/abdominal qi masses. Apply externally.
[Discussion]
The use of Youcai is generally considered merely to move stagnant blood and dissipate condensed qi. Who knows that it is sown in winter, endures frost and snow, and sends up shoots in spring. Its pungency enters the Zang organs. It first treats wandering wind and erysipelas swelling, as well as postpartum wind-blood syndrome, and cuts into various diseases of the heart and abdomen. The reason lies in the fact that the Wind Zang is originally the Blood Zang; stirring Yang to transform Yin relies on this. Therefore, when wind Qi moves, Blood can be transformed. If Blood does not transform, it leads to wind pathogenic factors overflowing. They function mutually and also cause pathology mutually. One must not ignore this herb's efficacy because it seems minor.
Meng Shen said: Those who already suffer from waist and leg conditions will find their symptoms worsen upon eating it. It also damages Yang Qi; excessive consumption causes sores and dental/oral diseases, and can generate various parasites in the abdomen.
[Xingren (Apricot Seed)]
Harvested in May. Seeds with two kernels are toxic and can kill humans; do not use.
Sweet, bitter, warm, cold, and draining in nature. (Moistening in property, promotes downward movement, but is not truly cold.) Has slight toxicity. Thin Qi and strong Flavor, turbid and sinking, possessing descending properties. Enters the Hand-Taiyin Lung Meridian. Can treat lung asthma/wheezing. Xingni (Apricot Seed) lowers wheezing, treating Qi disorders; Taoren (Peach Kernel) treats mania, treating Blood disorders. Both treat major illnesses, but one must not over-drain. Floating pulse indicates Qi disorder, use Xingren with Chenpi (Citrus Peel); deep pulse indicates Blood disorder, use Taoren with Chenpi. (Lung and Large Intestine are interior-exterior paired; Benmen governs incoming/outgoing, Pomen governs closure, serving as the channel for Qi, hence Chenpi is used to assist.) Decoct together with Tiandong (Asparagus Root) to moisten Heart and Lung. For Lung dryness with wheezing/heat and constipation of the Large Intestine, use Xingren peeled and ground finely. For every sheng (unit), add 1.5 sheng of water, pound into thick juice, add 4 liang of fresh ginger and 1 cun of licorice root, simmer slowly in a silver/ceramic vessel until a thin paste forms, add 2 liang of butter/ghee, and store. Each night, take one spoonful dissolved in boiling water. For chronic lung asthma and severe coughing, take 2 liang of Xingren peeled and tipped, soak in child's urine, changing once daily (3-4 times in summer). After half a month, remove, dry, and grind fine. Take an amount the size of a jujube pit each time, with one mint leaf, honey the size of a chicken egg, and one zhong of water. Decoct to 70%, take warm after meals. Within two doses, it will cure permanently. Avoid raw/fishy foods. For wind-deficiency headache feeling like bursting, use Xingren peeled and tipped... This method is miraculous... Mix with Qian Daidai (Lead Carbonate) one qian, make into cakes... Use three sheng of Xingren... Grind evenly and apply... Eyes... Head apply.
[Discussion]
The Classics state that Apricot is the Fruit of the Heart, but its seed treats Qi. It also states that Peach is the Fruit of the Lung, but its kernel treats Blood. Generally, Fire's... Yang. Qi is... Transformation... Heart leading to Qi... How can they be similar? Hu Youtong... Breaks coarse practitioners' scattering... Scattering Cold-Wind stagnation in Lung Meridian is particularly effective. However, if there is Yin deficiency with cough, or empty-heat/phlegm-heat in the Lung, it is contraindicated. (Zhong Chun)
[Processing]
Soak in boiling water, peel, remove tips, stir-fry with bran, then grind. Some do not peel or remove tips, utilizing their ability to disperse Cold-Wind Lung disease.
