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）

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.
