（音夫移。《拾遗》）
【释名】 杨（《古今注》）、
时珍曰∶ 乃白杨同类，故得杨名。按∶《尔雅》∶
唐棣， 也。崔豹曰∶ 杨，江东呼为夫 。圆叶弱蒂，微风则大摇，故名高飞，又曰
独摇。陆机以唐棣为郁李者，误矣。郁李乃常棣，非唐棣也。
【集解】藏器曰∶ 木生江南山谷。树大十数围，无风叶动，花反而后合，《诗》云∶
“棠棣之华，偏其反而”，是也。时珍曰∶ 杨与白杨是同类二种，今南人通呼为白杨，故
俚人有“白杨叶，有风掣，无风掣”之语。其入药之功大抵相近。
木皮

【校正】并入《唐本草》椋子木。
【释名】椋子木（音凉）。
时珍曰∶其材如松，其身如杨，故名松杨。《尔雅》云∶椋即来也。其阴可荫凉，故曰
椋木。
藏器曰∶江西人呼为凉木。松杨县以此得名。

郭璞云∶椋材中车辋。八月、九月采木，晒干用。
木
【气味】甘、咸，平，无毒。
【主治】折伤，破恶血，养好血，安胎止痛生肉（《唐本》）。
木皮
【气味】苦，平，无毒。
【主治】水痢不问冷热，浓煎令黑，服一升（藏器）。
（读音同“夫移”。出自《本草拾遗》）
【释名】杨（出自《古今注》）。
李时珍说：这是白杨的同类，所以得名“杨”。据考证，《尔雅》记载：唐棣，就是椋子木。崔豹说：椋子木，在江东地区被称为“夫椋”。它的叶子圆形，叶柄柔弱，微风一吹就会大幅摇晃，所以名叫“高飞”，又叫做“独摇”。陆机将唐棣解释为郁李，这是错误的。郁李实际上是常棣，不是唐棣。
【集解】陈藏器说：这种树生长在江南的山谷中。树干粗壮有十几围粗，没有风叶子也会动，花朵先开放后闭合，《诗经》中说：“棠棣的花，偏其然而开合”，指的就是这种树。李时珍说：椋子木与白杨是同一类的两种树，现在南方人通称为白杨，所以民间有“白杨叶，有风扯，无风扯”的说法。它们入药的功效大致相近。
树皮
【气味】味苦，性平，有小毒。
【主治】治疗风邪、血瘀引起的脚气疼痛痹症，破除损伤的瘀血，疼痛难以忍受。取白色树皮用火烤炙，用酒浸泡后服用。与五种树木的皮一起煮汤，用来擦拭治疗脚气，杀灭冻疮虫和风疹瘙痒。（陈藏器）
【发明】李时珍说：白杨皮、椋子木皮，混合五种树木的皮一起煮汤，浸泡并擦拭治疗跌打损伤、痹痛和各种肿痛。所谓的“五木”，是指桑树、槐树、桃树、构树、柳树。这些都能祛风和活血。
【附方】新增一方。
妇女白带崩漏：椋子木皮半斤，牡丹皮四两，升麻、牡蛎各一两。每次取一两，加酒两杯，煎至一杯，饭前服用。（出自《本草拾遗》）

【校正】并入《新修本草》中的椋子木条目。
【释名】椋子木（读音同“凉”）。
李时珍说：它的材质像松树，树干像杨树，所以名叫松杨。《尔雅》说：椋即来，意思是它。它的树荫可以遮阴纳凉，所以叫椋木。
陈藏器说：江西人称之为凉木。松阳县因此得名。
【集解】陈藏器说：松杨生长在江南的树林间。是大树，叶子像梨树。
苏颂记载：椋子木，叶子像柿子，两片叶子相对生长。果实细小圆润像牛李子，青色成熟后变黑。它的木质坚硬沉重，煮出的汁液呈红色。郭璞说：椋子的木材适合做车轮的辐条。八月、九月采集木材，晒干后使用。
木材
【气味】味甘、咸，性平，无毒。
【主治】治疗跌打损伤，破除恶血，滋养好血，安胎止痛，促进肌肉生长（出自《新修本草》）。
(Fu Yi, pronounced "Fu Yi". From *Bencao Shiyi* [Supplement to Materia Medica].)
[Names] Yang (from *Gujin Zhu*).
Li Shizhen states: It is a conspecific of the White Poplar (*Populus alba*), hence the name "Yang". According to research, *Erya* records: Tangdi is Liangzi Mu. Cui Bao stated: Liangzi Mu is called "Fu Liang" in the Jiangdong region. Its leaves are round with weak petioles; even a slight breeze causes them to sway greatly, thus named "Gao Fei" (High Flyer), also known as "Du Yao" (Sole Swaying). Lu Ji's interpretation of Tangdi as Yu Li was erroneous. Yu Li is actually Changdi, not Tangdi.
[Collection and Explanation] Chen Zangqi stated: This tree grows in the valleys of Jiangnan. The trunk is massive, measuring several chi in circumference. The leaves move even without wind, and the flowers open before closing. As the *Classic of Poetry* says: "The flowers of the Tangdi, fluttering open and closed," referring to this tree. Li Shizhen stated: Liangzi Mu and White Poplar are two species of the same category. Currently, people in the South generally refer to them as White Poplar. Hence, there is a folk saying: "White poplar leaves, pulled by wind, pulled by no wind." Their medicinal efficacy is roughly similar.
Bark
[Properties and Flavor] Bitter, neutral, slightly toxic.
[Indications] Treats wind-stroke, blood stasis, and painful bi-syndrome in the legs (foot qi). Breaks down damaged blood stasis where pain is unbearable. Take the white bark, roast it over fire, soak it in wine, and ingest. Boil it together with the barks of five types of trees to rub on foot qi, killing chigger-induced skin eruptions and wind-rash itching. Burn it into ash, place it in wine to normalize the taste, and it will not spoil over time (Chen Zangqi).
[Elucidation] Li Shizhen stated: Bark of White Poplar and Liangzi Mu, when mixed with the barks of five types of trees and boiled, can be used for soaking and rubbing to treat injuries, bi-syndrome, and various swellings and pains. The so-called "five trees" refer to Mulberry (*Morus alba*), Locust Tree (*Robinia pseudoacacia*), Peach (*Prunus persica*), Paper Mulberry (*Broussonetia papyrifera*), and Willow (*Salix babylonica*). All possess the functions of dispelling wind and invigorating blood.
[Attached Prescriptions] One new prescription.
Leukorrhea (White Discharge) in Women: 8 liang of Liangzi Mu bark, 4 liang of Moutan Cortex (Cortex Moutan), 1 liang each of Cimicifugae Rhizoma (Shengma) and Ostreae Concha (Muli). For each use, take 1 liang, add 2 cups of wine, decoct until 1 cup remains, and take before meals. (From *Bencao Shiyi*)
(From *Bencao Shiyi*)
[Correction] Merged into the entry for Liangzi Mu in *Xinxiu Bencao* [Newly Revised Materia Medica].
[Names] Liangzi Mu (pronounced "Liang").
Li Shizhen stated: Its timber resembles Pine (*Pinus*), and its trunk resembles Poplar (*Populus*), hence the name Songyang (Pine-Poplar). *Erya* states: "Liang" means "Lai" (to come/arrive). Its shade provides coolness, hence called Liangmu.
Chen Zangqi stated: People in Jiangxi call it Liangmu. Songyang County derived its name from this.
[Collection and Explanation] Chen Zangqi stated: Songyang grows among the forests of Jiangnan. It is a large tree with leaves resembling those of the Pear tree (*Pyrus*).
Su Song recorded: Liangzi Mu has leaves resembling Persimmon (*Diospyros kaki*), growing in opposite pairs. The fruit is small, round, like the cow plum, green when raw and black when ripe. Its wood is hard and heavy; the decoction is red in color. Guo Pu stated: Liang timber is suitable for making wheel spokes. Harvest the wood in August and September, dry it, and use.
Wood
[Properties and Flavor] Sweet, salty, neutral, non-toxic.
[Indications] Treats traumatic injuries, breaks down evil blood, nourishes good blood, calms the fetus, relieves pain, and promotes flesh regeneration (From *Xinxiu Bencao*).
Bark
[Properties and Flavor] Bitter, neutral, non-toxic.
[Indications] Treats watery dysentery regardless of cold or heat patterns. Decoct strongly until dark/black, and ingest 1 sheng (Chen Zangqi).
