【本草补遗】：泰西（西方）有锻树，吕宋（今菲律宾）也有这种树，树皮颜色发红，形状类似杜仲。起初是因为有人取树皮包裹切好的肉块，带回家后肉与皮粘合在一起成为一片，这才知道它的树皮能使肉和骨连接，因此命名为“锻树”。《本草》人参条目下记载的椴木读音为“贾”，而此处的“锻”读音为“断”，二者不同，可能是两种不同的树，应当与有见识的人辨别清楚。赵学敏按语：椴树的叶子与乌血树相似，但大如团扇，边缘有巨大的锯齿，刚长出来时可以包裹饼饵蒸着吃，霜降后叶子鲜红如同丹枫，照耀山谷岩石，其树皮柔韧如同麻皮，乌喇（今中国东北及俄罗斯远东地区）的人采集它来制作绳索、鱼网，入水不湿，还可以做鸟枪的火绳，这是中国所没有的。
治疗骨折、胎疝以及一切损伤，肌肉破裂、骨头断裂的情况，取树皮捣碎，用酒煎服，并将药渣敷在患处，伤口能完好如初。幼儿患有的疝气，如果是由于胎中带来的，表现为皮肤开裂，肠子进入阴囊，疼痛难忍，甚至能危及生命，将此叶长期贴在皮肤裂开的地方，自然会重新愈合，永远不再患病，但这只适用于非幼童年龄段的患者（注：此处原文逻辑似有矛盾或特指某种成人疝气或特定语境，依文直译）。方剂使用锻树皮，或者捣烂，或者削成片，用油润湿后粘在布上，贴在患处，外面用布牢固地系在腰间，半年或三个月后痊愈。
川槿皮
《边州闻见录》记载：四川多产黄葛树，宜宾学校宫墙前有一棵骑墙生长的树，根部还未到达地面，树干已需两人合抱。这棵树在某个月份种植，每年必定在某个月份才开始发芽。入药部位是根皮，药店中常取它的皮来代替川槿皮。
《峨眉山志》记载：嘉树位于罗目县东南三十里的阳山江边灌溉处，两棵树对植，每棵树的周长各二、三尺，向上延伸横向枝条，长达二丈，相互扶持连理，树荫可遮蔽百人，这种树名叫黄葛，号称嘉树。苏辙的诗：“我虽生于江阳却未曾见过嘉树”，指的就是这种树。
《益部谈资》记载：黄葛树的叶子像桂树枝梢那样大，圆润茂密遮盖数亩之地，冬春季节不凋谢，树干肿胀，根系都盘绕裸露在土面上，到了石崖旁边，则完全好像不依靠土壤生长一样，夔州的梁方最多，可惜没有木材用途。
按语：王阮亭《居易录》记载：云南多产黄果，比海棠稍大，香气像佛手柑，甘甜脆嫩像梨，汁液丰富，四川产的树只长果实但不结实，其皮类似川槿皮，也能治愈癣疾，现在说的黄葛，或许是音误罢了。
治疗疥癣，取它的根皮煎汤洗澡。
[Supplement to Materia Medica]: There is a tree called Duan Shu (Ironwood) in the Western regions, and it also exists in Luzon. Its bark is red in color and resembles Eucommia ulmoides (Duzhong). Initially, it was discovered when someone used its bark to wrap several pieces of cut meat; upon returning home, they found the meat had adhered to the bark as one piece, revealing that the bark has the property of binding flesh and connecting bones, hence the name "Duan Shu" (Ironwood). In the entry for Ginseng in the *Bencao*, there is a mention of Tilia wood (Duàn mù), pronounced "Jia", whereas this "Duan" is pronounced "Duan"; they are different, possibly two distinct species, and should be distinguished by experts. Zhao Xuemin notes: The leaves of Tilia resemble those of Wuxue (a type of tree), but are as large as a round fan, with large serrations. When young, they can be wrapped around cakes and steamed for consumption. After frost, the leaves turn bright red like maple leaves, illuminating the rocks and valleys. The bark is flexible and tough like hemp fiber. People in Wu-La (Northeast China/Russian Far East) harvest it to make ropes and fishing nets; it does not get wet in water and can also be used as slow-match cord for muskets. This is unavailable in China.
It treats fractures, congenital hernias, and all kinds of injuries, including ruptured muscles and broken bones. Take the bark, crush it, decoct it in wine, and ingest it. Apply the dregs to the affected area, and the injury will heal completely as if new. For infants suffering from hernias caused by congenital factors, where the skin cracks and intestines descend into the scrotum causing unbearable pain and potentially fatal outcomes, applying these leaves long-term to the cracked skin will naturally cause re-adhesion, preventing future issues permanently. However, this treatment is noted as not applicable to very young children [Note: Text implies specific age constraint or context]. The prescription uses Duan Shu bark, either crushed or sliced, moistened with oil, adhered to cloth, and applied to the lesion. Secure tightly with cloth around the waist for three to six months until healed.
Chuan Jin Pi (Broussonetia papyrifera Bark / Paper Mulberry Bark)
*Records of Observations from Border Regions*: Sichuan produces many Huang Ge trees (Ficus virens). One growing astride a wall in front of the Yibin school palace had roots that had not yet reached the ground, yet the trunk was thick enough to require two people's embrace. This tree is planted in a specific month and sprouts in another specific month each year. The medicinal part is the root bark. Medicine shops often use its bark as a substitute for Chuan Jin Pi.
*Chronicles of Mount Emei*: A fine tree located 30 li southeast of Luomu County at Yangshan River irrigation site. Two trees were planted opposite each other, each with a circumference of two to three chi. Their upper branches extended horizontally, spanning two zhang, intertwining and supporting each other, providing shade for a hundred men. This tree is named Huang Ge and hailed as a "Fine Tree". Su Zhe's poem states: "Though I was born in Jiangyang, I had never seen the Fine Tree," referring to this tree.
*Sources of Discussion in Yi Region*: Huang Ge leaves are as large as cassia twigs, lush and spreading to cover several mu. They do not shed leaves in winter and spring. The trunk is swollen, and roots coil exposed above the soil. Near cliff sides, they appear to grow without relying on soil. They are most abundant in Liangfang, Kuizhou, but unfortunately lack timber utility.
Note: Wang Ruanting's *Yiju Lu* records: Yunnan produces many Huang Guo fruits, slightly larger than crabapples, fragrant like Buddha's hand citron, sweet and crisp like pears, with abundant juice. Trees produced in Sichuan bear fruit but do not set seed. Their bark resembles Chuan Jin Pi and can also cure tinea. The current term "Huang Ge" may be a phonetic error.
To treat tinea corporis (scabies and ringworm), take the root bark, decoct it in water, and bathe in the solution.
