此即梓树之皮。梓亦有三种，当用拌素不腐者，方药不复用。叶疗手脚水烂。桐叶及此
以肥猪之法未见，其事应在
商丘子《养猪经》中耳。
〔谨案〕此三树，花叶取以饲猪，并能肥大，且易养。今见《李氏

猪使肥。今云敷猪疮并误讹也。《别录
蚀疮，汤浴之。并封敷嫩叶，

味甘、咸，平，无毒。主破血，产后血胀闷欲死者。水煮若酒煮五两，取浓汁服之，效。
此人用染色者，自南海昆仑来，交州、爱州亦有。树似 罗，叶若榆叶而无涩，抽条长
丈许，花黄，子生青、熟黑。

梓白皮：味苦，性寒，无毒。主治热证，驱除体内三种寄生虫，治疗眼部疾病。将花和叶捣碎后外敷可治疗猪的疮疡，用其喂猪可使猪长得肥大且易于饲养，效果是普通喂养的三倍。产于黄河地区。这就是梓树的树皮。梓树有三种，应当选用拌入素料不腐烂的那种，方药中不再使用其他种类。梓叶可治疗手脚因水浸而溃烂。桐叶以及此物用于给猪施肥的方法未见记载，此事应该记载在商丘子的《养猪经》中。
【考证】这三种树的花和叶用来喂猪，都能使猪长得肥大，而且容易饲养。现在看到的《李氏本草》及《博物志》，只说喂猪能使猪肥壮。现在文中说敷治猪疮并（误写为）蚀疮，汤浴之，并封敷嫩叶，主治烂疮，这是错误的讹传。
木天蓼：味甘、咸，性平，无毒。主治破血，产后血胀闷欲死之症。用水煮或酒煮五两，取浓汁服用，有效。这种植物有人用作染色，从南海昆仑而来，交州、爱州也有生长。树形类似罗树，叶子像榆树叶但没有涩味，枝条抽长可达一丈多，花黄色，果实初生青色，成熟后变黑。（新附）
另一种植物：味甘、苦，性平，无毒。主治跌打损伤，接续筋骨，祛除风痒龋齿。可用于制作洗浴的药汤。叶子像陆英，花也相似。但它是树木，高约一、二丈，木质轻虚无中心髓。砍下枝条插在地上就能生根，人家也种植它。又名木蒴，各地都有。（新附）
白石脂（注：原文此处描述似指某种植物根或果实，名为白石，实为“石蜜”或相关植物，依原文翻译）：味甘，性平，无毒。主治头风，少腹拘急。陆机说：一名木蜜。其树皮，性温，无毒。主治五种痔疮，与酒同服则味道变薄，这也是奇特的物品。这棵树径有一尺粗，木材名叫白石，叶子像桑树和柘树。它的果实成房状，像珊瑚，核在顶端，人们都食用它。（新附）
木蓼：味辛，性温，有小毒。主治症结、积聚，风劳虚冷。生于山谷中。它是藤蔓植物，叶子像柘树，花白色，果实像枣大小，形状不定。中间的瓤像茄子，味辛，采集时应当像姜蓼一样处理。将其苗藤切碎后用酒浸泡服用，或者用来酿酒，对去除风冷、症僻有极大疗效。各地都有，现在出产于安州、申州。（新附）
**Cortex Catalpae (Zi Bai Pi):** Bitter in taste, cold in nature, non-toxic. It primarily treats heat conditions, expels three types of intestinal parasites, and treats eye diseases. The flowers and leaves, when pounded and applied externally, treat sores on pigs; feeding it to pigs makes them fat and easy to raise, tripling the growth effect. Grows in the Yellow River region. This is the bark of the Catalpa tree. There are three types of Catalpa; one should use the variety that does not rot when mixed with plain feed. Other varieties are no longer used in prescriptions. The leaves treat maceration ulcers on hands and feet caused by water immersion. The method of using Toona leaves and this plant to fertilize pigs has not been seen; this matter should be recorded in Shangqiu Zi's "Classic of Pig Raising."
[Verification]: The flowers and leaves of these three trees, when used to feed pigs, can all make them fat and easy to raise. Current texts such as "Li's Materia Medica" and "Incredible Records of All Things" only state that feeding them makes pigs fat. The current text mentions applying to pig sores and treating erosion ulcers with decoction baths, and sealing fresh leaves to treat rotting ulcers, which is an erroneous distortion.
**Moutain Pepper Vine (Mu Tian Liao):** Sweet and salty in taste, neutral in nature, non-toxic. It primarily invigorates blood circulation and treats postpartum abdominal distension and suffocation sensation resembling death. Boil five liang in water or wine, take the concentrated juice orally; effective. This plant is used for dyeing by some, coming from Nanhai Kunlun; also found in Jiaozhou and Aizhou. The tree resembles Luo tree, leaves resemble elm leaves but without astringency, vines grow up to one zhang long, flowers are yellow, fruits are green when young and black when ripe. (Newly Added)
**Another Plant:** Sweet and bitter in taste, neutral in nature, non-toxic. It primarily treats traumatic injuries, knits bones and sinews, dispels wind-induced itching, and treats dental caries. Can be used for medicinal bathing. Leaves resemble *Sambucus* (Lu Ying), flowers are similar. However, it is a tree, about one or two zhang high, wood is light and hollow. Branches inserted into the ground take root easily; households also plant it. Also known as Mu Shuo, found everywhere. (Newly Added)
**Bai Shi (White Stone/Plant):** Sweet in taste, neutral in nature, non-toxic. It primarily treats head wind (cephalalgia due to wind) and tension/cramping in the lower abdomen. Lu Ji states: also known as Mu Mi (Tree Honey). Its bark is warm in nature and non-toxic. It primarily treats five types of hemorrhoids; mixing with wine makes the taste thinner; this is also a unique substance. The tree trunk is one chi in diameter, the wood is named Bai Shi, leaves resemble mulberry and Zhe tree. Fruits are pod-like, resembling coral, with seeds at the tip; people eat them. (Newly Added)
**Polygonum (Mu Liao):** Pungent in taste, warm in nature, slightly toxic. It primarily treats fixed masses (Zheng Jie), accumulations, wind-wasting deficiency-cold. Grows in mountain valleys. It is a vine, leaves resemble Zhe tree, flowers are white, fruits are date-sized with indefinite shape. The pith resembles eggplant, pungent in taste; harvesting should follow the method of Jiang Liao. Cutting the seedlings and vines, soaking in wine and taking orally, or brewing wine with them, greatly eliminates wind-cold and asymmetrical paralysis. Found everywhere, currently produced in Anzhou and Shen Zhou. (Newly Added)
