按∶胡桃，达命门之品也。夫三焦者，元气之别使，命门者三焦之本源，盖一源一
委也。命门指所居之府而名，乃藏精系胞之物，三焦指分治之部而名，乃出纳熟腐之
司，一以体名，一以用名，在两肾之间，上通心肺，为生命之源，相火之主，《灵枢》
已详言，而扁鹊不知源委体用之分，以右肾为命，以三焦为有名无状，承讹至今，莫之
能正，胡桃仁颇类其状，外之皮汁皆黑，故入北方通命门，命门即通，则三焦利，故止
通于肺耳。昔幼儿痰喘，五日不乳，其母梦大士授方，令人参胡桃煎汤，灌之即愈。次
日胡桃去衣服之，其喘复作，仍连皮煎服仍效。盖人参定喘，胡桃润肺，皮有敛肺之功
也。空腹时连皮食七枚，大能固精壮阳，但命门火炽者勿服。
胡桃肉禀受火与土二气而生，味道甘甜，性质温热，无毒。因其性润且多热，所以是补益命门（肾间动气，为元气之根）的药物。它能使人身体肥壮健壮，滋润肌肤，使须发变黑，固摄精气，增强性功能并助起阳事。小儿或产妇出现气喘症状时，将带壳的胡桃与人参一起煎煮服用，即可痊愈。这是因为人参能平定气喘，胡桃能润肺，而胡桃皮更有收敛肺气的作用。多吃胡桃能通利小便，是因为它能入肾固精，使水液代谢的通道常通。外用敷治瘰疬（颈部淋巴结结核），是利用其甘温之性能解毒散结；去除五痔（五种痔疮），是取其润肠除湿的功效。误吞铜钱，多吃胡桃可使其排出，这是物性相克的原因。长期食用会导致眉毛脱落，因为热极生风，风盛则万物摇落之象。胡桃的青皮（未成熟果实的果皮）性涩，因此可用于染胡须。与补骨脂、蒺藜、连须（可能指某种草药或特指部位）、鹿茸、麦冬、巴戟天、覆盆子、山茱萸、五味子、鱼鳔胶等同用，是补益命门、促进生育的最有效方剂。
治疗血崩不止：用胡桃肉十五枚，烧至存性（烧焦但保留药性）。研成粉末作为一次剂量，空腹时用温酒调服，效果神奇。治疗便毒初起（肛周脓肿等），用胡桃七个，烧后研末，酒送服，不超过三次即见效。治疗鱼口便毒（腹股沟淋巴结炎），在端午节的午时，采集树上青色的胡桃，放在筐中阴干，临用时全部烧成粉末，酒送服，稍行一二次后，若有脓液会从大便排出，若无脓液则会消散，二三服后即可平复痊愈。以上两个方子，加入全蝎、穿山甲效果更好。治疗跌打损伤，将胡桃仁捣碎，配合温酒顿服，病即好转。
胡桃肉，经常食用可健身生发，兼补下元（肾气）。但多吃会动风生痰，且助长肾火。将其烧熟擂成细末，混合松脂，治疗瘰疬容易痊愈。人拔除白须后，将胡桃粉纳入毛囊孔中，须发即变黑。外伤损伤配合醇酒热服，石淋（尿路结石）掺碎米煮食尝味，经脉非常通畅，血脉得以滋润。吃酸的东西导致牙齿酸痛，细嚼胡桃立除。胡桃味甘气热，能养血润肠，收敛肺气治疗气喘，强壮痿证，增强性功能，止腰脚虚冷，使肌肤光泽，上能通利三焦之气，下能补益命门之火，佐以补骨脂，有水木相生之妙。
主治（痘疹合参）：痘疹初起时适宜食用，灌浆期宜少食，泄泻虚滑者禁用。
按语：胡桃，是通达命门的药物。三焦是元气的别使，命门是三焦的本源，可谓一源一委。命门因其所居之府而得名，是藏精系胞之物；三焦因分治之部而得名，是出纳熟腐之司。一个以体命名，一个以用命名，位于两肾之间，上通心肺，为生命之源，相火之主，《灵枢》已有详言。但扁鹊不知源委体用的区别，认为右肾为命门，认为三焦有名无状，沿袭错误至今，无人能纠正。胡桃仁颇似命门之状，外皮汁液皆黑，故入北方通命门。命门通则三焦利，故亦通于肺。昔日幼儿患痰喘，五日不进食，其母梦见观音大士传授方子，让人用人参和胡桃煎汤灌服，即愈。次日胡桃去皮后服用，气喘复发，仍连皮煎服又见效。大概人参能定喘，胡桃能润肺，皮有敛肺之功。空腹时连皮吃七枚，大能固精壮阳，但命门火炽盛者勿服。
Walnut Kernel (Hetaoren) is generated by inheriting the Qi of Fire and Earth. Its taste is sweet, its nature is hot, and it is non-toxic. Due to its moistening property and heat, it serves as a medicine to benefit and tonify the Mingmen (Gate of Vitality, the root of Yuan Qi). It makes people fat and strong, moisturizes the skin, blackens beard and hair, secures essence and Qi, strengthens sexual function, and promotes Yang rising. For children or postpartum women suffering from asthma (wheezing), decocting walnuts with shell together with Ginseng Radix et Rhizoma (Renshen) can cure the condition. This is because Ginseng stabilizes asthma, Walnut Kernel moistens the lungs, and the walnut shell has the effect of astringing Lung Qi. Eating more walnuts promotes urination because it enters the Kidney to secure essence, keeping the water passages open. Applied externally for scrofula (tuberculous lymphadenitis), its sweet and hot nature detoxifies and dissipates nodules; removing five types of hemorrhoids relies on its ability to moisten the intestines and drain dampness. If copper coins are accidentally swallowed, eating many walnuts helps expel them due to the antagonism of material properties. Long-term consumption may cause eyebrows to fall out, as extreme heat generates wind, and excessive wind leads to the shaking and falling of all things. The green skin (unripe pericarp) of the walnut is astringent and thus used for dyeing mustaches. Combined with Psoraleae Fructus (Buguzhi), Tribuli Fructus (Jili), Deer Antler Glue (Lurong), Ophiopogonis Radix (Maidong), Morinda Officinalis Root (Baji), Rubi Fructus (Fupenzi), Cornus Officinalis Fruit (Shanzhuyu), Schisandrae Fructus (Wuweizi), and Fish Maw (Yujiao), it is most effective for tonifying the Mingmen and promoting fertility.
For intractable metrorrhagia (uterine bleeding): Use fifteen Walnut Kernels, charred until carbonized but retaining medicinal properties (Cunxing). Grind into powder for one dose, taken orally with warm wine on an empty stomach; the effect is miraculous. For early-stage perianal abscess (Biudu), use seven walnuts, charred and ground, taken with wine; effective within three doses. For inguinal lymphadenitis (Yukou Biudu), collect green walnuts from trees at noon on the Dragon Boat Festival, dry them in shade in a basket, and burn them completely to powder when needed. Taken with wine, after one or two doses, pus will be excreted via stool if present, or the swelling will subside if not. Two to three doses lead to recovery. Adding Scorpion (Quanxie) and Pangolin Scales (Chuanshanjia) to these formulas enhances efficacy. For traumatic injuries, crush Walnut Kernels and take immediately with warm wine for quick recovery.
Walnut Kernel, when consumed frequently, benefits health and promotes hair growth, while also tonifying the Lower Origin (Kidney Qi). However, excessive intake generates wind and phlegm and aids Kidney fire. Charred and ground into fine powder, mixed with Pine Resin (Songzhi), it easily heals scrofula. After plucking white hairs, inserting Walnut Powder into the follicles turns them black. For injuries, take with pure wine heated; for urinary calculi (Shilin), boil with broken rice and consume; this unblocks meridians and nourishes blood vessels. For toothache caused by sour food, chewing Walnut Kernel thoroughly provides immediate relief. Walnut Kernel is sweet and hot in nature; it nourishes blood, moistens intestines, astringes Lung Qi to treat asthma, strengthens flaccidity, enhances sexual function, stops coldness in waist and legs, makes skin lustrous, benefits Upper Sanjiao Qi, and tonifies Mingmen Fire below. When assisted by Psoraleae Fructus, it creates a wonderful interaction of Water generating Wood.
Main Indications (Combined Analysis of Smallpox and Rash): Suitable for consumption during the initial stage; reduce intake during the pustule-filling stage; contraindicated for those with diarrhea and loose stools.
Commentary: Walnut is a substance that reaches the Mingmen. The Sanjiao (Triple Burner) is the special envoy of Yuan Qi, and the Mingmen is the source of the Sanjiao; they share one origin and one destination. The Mingmen is named after its residence, being the organ that stores essence and connects to the uterus. The Sanjiao is named after its functional zones, being the department responsible for digestion and metabolism. One is named by form (Ti), the other by function (Yong). Located between the two kidneys, connecting upwards to the Heart and Lungs, it is the source of life and the master of Ministerial Fire. The *Ling Shu* has detailed this, but Bian Que did not understand the distinction between origin/destination and form/function, mistakenly identifying the right kidney as the Mingmen and considering the Sanjiao to have name but no form. This error has persisted to this day without correction. Walnut Kernel resembles the shape of the Mingmen; its outer skin and juice are black, corresponding to the North, thus entering and communicating with the Mingmen. Once the Mingmen is unblocked, the Sanjiao becomes smooth, and thus it also communicates with the Lungs. In the past, a young child suffered from phlegm-asthma and refused milk for five days. The mother dreamed of Guanyin Bodhisattva prescribing a formula: decoct Ginseng and Walnut Kernel and administer it, which cured the child. The next day, when the walnut was taken without the shell, the asthma returned. Taking it again with the shell proved effective. This is because Ginseng stabilizes asthma, Walnut Kernel moistens the lungs, and the shell has the function of astringing Lung Qi. Eating seven walnuts with the shell on an empty stomach greatly secures essence and strengthens Yang, but should be avoided by those with blazing Mingmen fire.
