Purges fire, cools blood.
Slightly pungent, sweet, and cold in nature. Cools blood. Treats hematemesis (vomiting blood), epistaxis (nosebleed), intestinal wind with lower bleeding, and burns/scalds. (Mix with sesame oil for topical application.) Use the red variety. The seeds are used to treat difficult labor in women.
Grind into powder and sprinkle.
Moistens the liver and brightens the eyes.
Sweet and slightly cold. Moistens liver dryness. Treats red vessels in the eyes, blindness (qingmang), corneal opacity (fuyu), eye swelling with discharge and tearing, photophobia, and pediatric malnutrition affecting the eyes.
Produced in Shu region. Trees grow over one zhang high. Leaves do not fall in winter. Flowers are dense and fluffy, hence the name. Select clean material, moisten with wine, and bake. (Mix with 1 liang of *Buddlejae Flos* (Mimenghua) and 1 liang of *Phellodendri Cortex* (Huangbolgen) end, make water pills the size of wutong seeds, take 10-15 pills with warm water before sleep; effective for corneal opacity.)
Purges fire, breaks stasis.
Bitter, pungent, warm, toxic, and fierce. Treats numbness from wind-toxin, and stagnant blood from trauma. (Its qi is fierce and vigorous, can open blockages, immediately stops pain and dripping; use with caution in deficient persons.) Trees are two or three chi high. Leaves resemble *Firmiana simplex* (Chou Wutong) but have eight angles. White flowers bloom in clusters in autumn. Use the bark near the roots.
Unblocks, opens orifices, induces labor.
Bitter and neutral. Descends to unblock orifices. Mainly treats difficult labor and induces delivery. This wood is tough and can be used as a chisel handle, hence the common name "Chaozi Mu" (Chisel Wood). For transverse or breech presentation, use an old chisel handle. Since it has been struck by axes many times and is curled, it is especially effective. Leaves treat swelling, toxins, and carbuncles.

Purges fire, slips phlegm, moistens dryness.
Sweet, bitter, cold, and slippery. Clears phlegm and descends fire. (For deficient persons, it should be used with *Ren Shen* (Ginseng); Ren Shen secures the meridians, while Zhu Li (Bamboo Sap) unblocks collaterals, so their sweet-cold properties complement each other.) Treats stroke with locked jaw. (*Bencao Jing Shu* states: This is a key herb for stroke. Generally, stroke is caused by yin deficiency with hyperactive fire and phlegm-heat congestion. If it were due to external wind pathogen, how could such a cold-slippery herb be used? [It is for] severe heat from phlegm confusing the mind. (Zhu Danxi said: Phlegm located in meridians, limbs, and subcutaneous tissues cannot reach these areas without this herb. Li Shizhen said: Bamboo sap is cold and slippery, suitable for those with phlegm due to wind-heat, dryness, or fire. However, if taken by those with cold-dampness, stomach deficiency, or loose bowels, it will damage the spleen and stomach. Shoots are slippery and purgative; excessive consumption causes diarrhea. Monks refer to shoots as "intestine-scraping combs," which means the same thing.) Sudden toothache. (Burn bitter bamboo to obtain sap, apply hot to the affected area.) Wind spasms, mania, spontaneous sweating, irritability, thirst, and regurgitation. (Cook with rice to make porridge.) Contraindicated in cold stomach and loose bowels. (Bamboo damages qi, so it is unsuitable for deficient persons to eat shoots.) There are many types of bamboo. *Danzhu* (Light Green Bamboo) has thin flesh, powder between nodes, juicy and sweet, considered the best. *Gangzhu* (Hard Bamboo) is tough with short nodes and white frost-like skin. *Kuzhu* (Bitter Bamboo) has a thick base, long broad leaves, and bitter shoots. Only these three types are used medicinally. Extract bamboo sap using the same method as extracting *Jingli* (Bamboo Sap from Jujube branches). Use *Sheng Jiang* (Fresh Ginger) juice as an adjuvant (Ginger eliminates phlegm and balances the cold nature, so they are often used together. For infant lip ulcers, mix bamboo sap with *Huang Lian* (Coptis Rhizome), *Huang Bai* (Phellodendron Bark), and *Dan Sha* (Red Lead) for topical application; effective.)
