味苦，性寒，无毒。主治恶蚀疮（一种腐蚀性溃疡）附着于阴部。桐树皮，主治五痔（五种痔疮），杀灭三虫（蛔虫、蛲虫、绦虫等寄生虫），治疗贲豚气病（气从少腹上冲心胸的病症）。
桐花，主治涂抹治疗猪身上的疮疡。用桐叶喂猪，可使猪肥大三倍。生长在桐柏山谷。
陶隐居说：桐树有四种，青桐，叶子和树皮呈青色，类似梧桐但没有果实。梧桐，树皮白色，叶子像青桐但有果实，果实与桐子没有区别，只有花和果实不同，花在二月开放，呈黄紫色，《礼记》说：“桐树开始开花时，是制作琴瑟的好材料。”现在这里提到的是花，那应该是白桐，白桐可以用来制作琴瑟，又名椅桐，人们家中多种植它来治疗疮疡。恐怕是错误的。哪有故意弄破受伤的猪去敷桐花的道理呢？臣禹锡等人按照《尔雅疏》说：榇，又名梧。郭璞注：就是现在的梧桐。《诗经·大雅》说：“梧桐生长在那里，在朝阳的山坡上。”又说：桐木，又名荣。郭璞注：就是梧桐和榇梧是同一种东西。《药性论》说：白桐皮，能治疗五淋（五种淋证）。洗头去除头风，促进头发生长并滋润。
日华子说：桐油，性冷，微毒。涂抹治疗恶疮疥癣及宣通水肿，涂抹被老鼠咬伤处，能驱避老鼠。
《图经》说：桐，生长在桐柏山谷，现在到处都有。它的种类有四种。旧注说：青桐，枝条和叶子都是青色而没有果实；梧桐，树皮白色，叶子青色而有果实，果实肥大美味可食用；白桐，有花和果实，它在二月开放，呈黄紫色，又名椅桐，又名黄桐，这就是药物中所用的花、叶的来源；岗桐，像白桐，只是没有果实，就是用来制作琴瑟的那种。陆机《草木疏》说：白桐适宜制作琴瑟。云南人，将其纤维绩成布，类似毛布。所以制作琴瑟适宜用岗桐、白桐两种。
梧桐有两种，都带有“椅”的名称。有人说：梧桐可以知晓日月正闰。长出十二片叶子，一边六片，从下数一片代表一个月，到上面第十二片叶子。如果有闰月则长第十三片叶子，较小的部分表示余数。观察它，就知道是哪个月份有闰月。所以说梧桐不生长则九州气候异常，或者说现在南方人榨油的，乃是岗桐，这种桐也有果实，比梧桐子稍大而已。江南有红桐，秋天开红花，没有果实。有紫桐，花像百合，果实可以糖煮食用。岭南有刺桐，叶子像梧桐，花朵侧面展开如手掌，枝干有刺，花色深红。主治金创（金属利器造成的创伤）殊效。另外梧桐白皮，也主治痔疮。《删繁方》治疗肠道中生痔，肛门边有核状的，用猪蹄甲青色部分配合使用，其膏剂涂抹疮口，并酒送服。
《子母秘录》：治疗痈疮疽痔恶疮，小儿丹毒。用桐皮，水煎，外敷。
《衍义》说：桐叶，《本草经》注没有指定是何种桐，导致难以确切使用。现在列出四种桐，各有治疗条目，其性状列在后面：一种白桐，可以砍伐制作琴的，叶子三叉，开白花，也不结种子。《药性论》说：皮能治疗五淋，洗头，去除头风，生发。一种荏桐，早春先开淡红花，形状像鼓子花成筒状，果实或可作桐油。日华子说：桐油，性冷，微毒。一种梧桐，四月开淡黄小花，一如枣花。枝头出丝，落地成油，沾湿衣服鞋子。一种岗桐，无花，不中用作琴，体重。
Tong Ye (Folium Firmianae / Firmiana simplex)
Bitter in taste, cold in nature, non-toxic. Primarily treats *e shi chuang* (malignant erosive ulcers) adhering to the yin region. The bark primarily treats *wu zhi* (five types of hemorrhoids), kills three parasites (*san chong*), and treats *ben tun qi* (a condition characterized by Qi rushing from the lower abdomen to the chest).
The flowers are used topically to treat sores on pigs. Feeding Tong leaves to pigs can increase their weight by three times. It grows in the valleys of Tongbai Mountain.
Tao Hongjing states: There are four types of Tong trees. Qing Tong (Green Tong): leaves and bark are green, resembling Wutong but without seeds. Wutong (Chinese Parasol Tree): bark is white, leaves resemble Qing Tong but have seeds; the seeds are similar to those of Bai Tong, differing only in flower and fruit. Flowers open in the second lunar month, yellowish-purple. The *Book of Rites* states: "When the Tong tree begins to bloom, it is suitable for making qin and se instruments." Since this text mentions flowers, it likely refers to Bai Tong (White Tong). Bai Tong is suitable for making musical instruments, also known as Yi Tong, and is commonly planted in households. Regarding its use for treating sores, this seems erroneous. How could one intentionally apply Tong flowers to a broken pig? Ministers Yuxi et al., according to the commentary on *Erya*, state: Chen is another name for Wu. Guo Pu notes: This is the current Wutong. The *Classic of Poetry · Daya* says: "Wutong grows there, on the sunny slope." It also states: Tong wood is also called Rong. Guo Pu notes: Wutong and Chenwu are the same species. *Yaoxing Lun* states: Bai Tong bark can treat *wu lin* (five types of strangury). Washing hair with it removes *tou feng* (wind affecting the head) and promotes hair growth and nourishment.
Ri Hua Zi states: Tong oil is cold in nature and slightly toxic. Applied externally for malignant sores, scabies, and edema; applied to rat bites to repel rats.
*Tujing* states: Tong grows in Tongbai Valley and is now found everywhere. Its varieties include four types. Old annotations say: Qing Tong has green branches and leaves and no seeds; Wutong has white bark, green leaves, and edible seeds; Bai Tong has flowers and fruits, blooming in the second month with yellowish-purple flowers, also known as Yi Tong or Huang Tong; these are the parts used in medicine. Gang Tong resembles Bai Tong but lacks seeds and is used for making instruments. Lu Ji's *Caomu Shu* states: Bai Tong is suitable for making instruments. People in Yunnan weave its fibers into cloth similar to wool cloth. Thus, Gang Tong and Bai Tong are suitable for instrument making.
There are two types of Wutong, both bearing the name "Yi". Some say: Wutong indicates leap months. It grows twelve leaves, six on each side. Counting from the bottom, one leaf represents one month up to the twelfth. A thirteenth leaf appears in leap years, with smaller variations indicating surplus/deficit. Observing it reveals which month has the intercalary month. Hence, "If Wutong does not grow, the nine provinces differ." Alternatively, the tree used for oil production in the south is Gang Tong, which has larger seeds than Wutong. In Jiangnan, there is Hong Tong (Red Tong) that blooms red flowers in autumn without fruit. Youzi Tong (Purple Tong) has lily-like flowers and fruits edible after sugar boiling. In Lingnan, there is Ci Tong (Thorny Tong) with Wutong-like leaves, palm-shaped deep red flowers, and thorny stems. It is highly effective for *jin chuang* (metal-induced wounds). Additionally, Wutong white bark treats hemorrhoids. *Shanfan Fang* treats intestinal hemorrhoids with nodules at the anus, using the green part of pig trotters; the ointment is applied to sores and taken with wine.
*Zimu Milu*: Treats carbuncles, ulcers, hemorrhoids, malignant sores, and infant erysipelas. Use bark, decoct in water, and apply externally.
*Yanyi* states: The *Jing* annotation does not specify which Tong, causing difficulty in application. Now listing four types with treatments: One is Bai Tong, suitable for carving qins, with trifid leaves, white flowers, and no seeds. *Yaoxing Lun* states: Bark treats strangury, washes hair, removes head wind, and promotes hair growth. One is Ren Tong, blooming pale red flowers early in spring, tubular like drum flowers, seeds used for oil. Ri Hua Zi states: Tong oil is cold and slightly toxic. One is Wutong, blooming pale yellow small flowers in April like jujube flowers, producing silk-like threads that fall and create oil stains on clothes. One is Gang Tong, without flowers, unsuitable for instruments, and heavy in weight.
