主大便下血。今近道处处有之。夏中生荚，樗之有花者无荚，有荚者无花，常生臭樗
上，未见椿上有荚者。然世俗不辨椿、樗之异，故俗中名此为椿荚，其实樗荚耳。（新定）

主治大便下血。如今在附近道路处处都有生长。夏季中间生出荚果，樗树中有花的没有荚果，有荚果的没有花，常生长在臭椿树上，未见香椿树上有荚果的。然而世俗之人不分辨香椿和樗树的差异，所以俗世中称此为香椿荚，其实它是樗树的荚果。（新定）衍义本草在椿木条目下已有详细记载。
水杨叶
嫩枝，味苦，性平，无毒。主治久痢赤白（长期腹泻伴有红色和白色粘液），捣碎后加水绞取汁液，服用一升，每日两次，效果显著。如今注释中的水杨叶，叶片圆而宽阔且呈红色，枝条短硬，多生长在水岸边。树木与杨柳相似，既生长在水岸边，所以名叫水杨。（唐本先附）图经本草在白杨条目下已有详细记载。
味苦，性寒，有毒。主治痈疽恶疮，用水煮叶汁清洗疮口，立即痊愈。生长在篱笆墙垣之间。又名空疏。各地都有生长。（唐本先附）
味道辛辣如花椒。主治游蛊（一种游走性的寄生虫病或邪气致病），飞尸着喉、口者（一种突然发作、感觉有异物冲击咽喉口腔的病证），刺破皮肤后用种子擦拭令其出血，应当排出涎沫。煮汁服用，可去除暴发性冷痛腹痛，食物不消化，杀灭腥物毒性。树木高大硕壮，茎干有刺。（新补 见陈藏器。）图经本草在蜀椒条目下已有详细记载。
性微温。主治霍乱吐泻不止。
陶隐居说：削成柿饼状煮服，穷困无其他药物时可用此药。臣禹锡等谨按日华子说：味辛，性热，微毒。治疗转筋（肌肉痉挛）。
衍义说：楠木，如今江南等路的造船场，都用这种木材。因为木质坚硬且善于浮于水面。时间久了多中空，被白蚁蛀穴。
味甘，性温，无毒。主治补虚损。取白皮及向东生长的根白皮，煮汁酿酒，主治风虚耳聋，劳损虚羸瘦（因劳累损耗导致的身体虚弱消瘦），腰肾冷，梦中与人交接泄精者。取汁服用，无刺的为良。木部主治妇人崩中血结（妇女非经期大量出血及瘀血阻滞），以及主治疟疾，兼可用来染黄。（新补 见陈藏器、日华子。）
衍义说：柘木，里面有纹理，也可旋制为器具。叶子喂蚕叫柘蚕，叶梗，但不如桑叶好。向东生长的根及皮，煮汁酿酒，治疗风虚耳聋有疗效。其余内容如《经》所述。
Indicated for hematochezia (blood in stool). It is now found everywhere along nearby roads. Pods are produced in mid-summer; the *Broussonetia papyrifera* (Paper Mulberry, 樗) that has flowers does not have pods, and the one with pods does not have flowers. It commonly grows on the stink paper mulberry (*Broussonetia papyrifera*, 臭樗), and no pods have been seen on the Chinese toon (*Toona sinensis*, 香椿). However, laypeople do not distinguish between the Chinese toon and the paper mulberry, so it is vulgarly called "Chinese toon pod," but it is actually a paper mulberry pod. (Newly determined) The *Yanyi Bencao* (Supplementary Meaning Materia Medica) details are under the entry for Paper Mulberry Wood.
Water Willow Leaf
The tender branches taste bitter, are neutral in nature, and non-toxic. They indicate long-standing dysentery with red and white discharge (久痢赤白). Crushed and mixed with water, the juice is extracted and taken, one sheng per dose, twice daily, with great efficacy. The current annotation describes the Water Willow leaf as round, broad, and reddish, with short and stiff branches, often growing by the water's edge. The tree resembles willow and poplar; since it grows by the water, it is named Water Willow. (Tang Benxian Appendix) Details are under the entry for White Poplar in the *Tujing*.
Tastes bitter, is cold in nature, and toxic. It indicates carbuncles and malignant sores (疽恶疮). Wash the sores with the juice obtained by boiling the leaves in water, and they will heal immediately. It grows among fences and walls. Also known as Kongshu (Empty and Sparse). It is available everywhere. (Tang Benxian Appendix)
Tastes pungent and spicy like Sichuan pepper. It indicates wandering gu pathogen (游蛊) and Feishi attacking the throat and mouth (飞尸着喉、口者). Prick the skin and rub with the seeds until blood flows, which should cause the expulsion of saliva and phlegm. Boil the juice and take it orally to remove sudden cold abdominal pain, indigestion, and to neutralize the toxicity of fishy substances. The tree is tall and robust, with thorny stems. (Newly supplemented, see Chen Cangqi.) Details are under the entry for Shu Pepper in the *Tujing*.
Slightly warm in nature. It indicates cholera-like syndrome with continuous vomiting and diarrhea (霍乱吐下不止).
Master Tao Hongjing stated: Cut into slices and boil to take orally; when poor and lacking other medicines, this can be used. Minister Yuxi et al. respectfully note according to Ri Hua Zi: Tastes pungent, is hot in nature, and slightly toxic. It treats muscle cramps (转筋).
The *Yanyi* states: Nanmu (Nan wood) is used in shipyards in Jiangnan and other circuits today. Because the wood is hard and floats well on water, it often becomes hollow over time and is bored by termites.
Tastes sweet, is warm in nature, and non-toxic. It indicates tonifying deficiency and damage (补虚损). Take the white bark and the white bark of roots growing towards the east, boil them to make wine, and it indicates wind-deficiency deafness (风虚耳聋), exhaustion-induced emaciation and weakness (劳损虚羸瘦), coldness of the waist and kidneys, and seminal emission during dreams of sexual intercourse. Take the juice; those without thorns are superior. The wood indicates metrorrhagia and blood stagnation in women (妇人崩中血结), malaria (疟疾), and can also be used for yellow dyeing. (Newly supplemented, see Chen Cangqi, Ri Hua Zi.)
The *Yanyi* states: Zhemu (Cudrania tricuspidata wood) has grain patterns inside and can also be turned into vessels. Leaves fed to silkworms produce Zhesilkworms; the leaf stalks are inferior to mulberry leaves. The roots growing towards the east and the bark, boiled to make wine, treat wind-deficiency deafness effectively. The rest is as described in the Classics.
