Rushu (Shu Li, *Ziziphus jujuba* var. *spinosa*), also known as Wuzhaozi. The *Shennong Bencao Jing* does not record the specific provinces or regions of origin, but states that it grows in fields and meadows; it is now abundant in the Shuchuan region. Its branches and leaves resemble those of the plum tree (*Prunus salicina*), and its fruit resembles *Schisandrae Chinensis Fructus* (Wuweizi, Schisandra Berry), being black in color with purple juice. It has a sweet and bitter taste. Harvest when the fruit is ripe and dry in the sun. After nine steaming processes and soaking in wine, it can promote the discharge of blood stasis. The bark can be harvested at any time and is also called Niuli. Liu Yuxi's *Chuanxin Fang* records: It treats gan sores in the mouths of adults and Fabei (a severe carbuncle on the back). Using the root of Shan Lizhi (Mountain Plum, also known as Niuzi) is effective without fail; wild Rosa roots are preferred. Cut five sheng of the herbs finely, add five dou of water, and decoct for half a day until the liquid is concentrated. Transfer to silver or copper vessels, then heat over boiling water until reduced to one or two sheng. When slightly thickened, store in porcelain bottles. Take small amounts, warm, hold in the mouth, and swallow slowly; recovery is certain. Avoid soy sauce, vinegar, greasy foods, and hot noodles; generally, meat should not be consumed. For Fabei, decoct the liquid over boiling water until extremely thick, mix into a paste, apply to the sore with cloth, which is miraculous. Dou Shi, wife of Liu An, Military Officer of Xiangzhou, suffered from oral gan for fifteen years, losing all her teeth and having her gums destroyed and broken, making it unbearable to approach. She recovered using this prescription.

Luanhua (Luan Flower), grows in river valleys of Hanzhong. It is occasionally found in gardens and nurseries in the south and around the capital. The leaves are similar to *Hibiscus mutabilis* (Mujin, Cotton Rose Hibiscus) but thinner and finer; the flowers are yellow like *Sophora japonica* (Huaihua, Pagoda Tree Flower) but slightly larger and longer; the seed pods resemble *Physalis alkekengi* (Suanjiang, Chinese Lantern Fruit), containing seeds inside like ripe peas, round, black, hard, and suitable for making prayer beads. Harvest the flowers in May; they can also be used for dyeing yellow. Southerners combine them with *Coptidis Rhizoma* (Huanglian, Coptis Rhizome) to make a decoction, which is highly effective for treating red and ulcerated eyes (Mu Chi Lan).

Shancai (Fir Wood), old texts do not record the provinces or regions of origin. It is now abundant in deep mountains in the south. The wood is similar to pine but strong and straight; the leaves grow attached to the branches like needles. (*Erya* states: Pi, pronounced "bi", same meaning as Shan. Guo Pu's commentary notes: Similar to pine, grows in Jiangnan. Can be used for boats and coffins; pillars buried underground do not rot. People commonly use it for barrel boards, which are very water-resistant. Physicians boil the knots/joints to extract juice, soak and rub Hongjiaojiao (Hongjiaojiao, a condition characterized by swelling and pain in the ankles/feet), which is particularly effective. In Tang Dynasty Liu Zongyuan's *Jiu Sansi Fang* (Prescriptions to Save Three Deaths): In the second month of the 12th year of Yuanhe, he contracted Hongjiaojiao. At midnight, his qi became blocked and cut off, with a lump under the ribs as large as a stone. He was near death, unconscious for three days due to severe cold, while his family wept. Zheng Xunmei of Yingyang transmitted the Shanmu Tang (Fir Wood Decoction). After taking half a shiqing (approx. 30 mins), he had a massive bowel movement. After three doses, his qi flowed and spirit returned. Ingredients: One dasheng of fir wood joints, one dasheng of chopped orange leaves (if unavailable in the north, substitute with bark), seven Dafu Binglang (Areca Seed, *Arecae Semen*) crushed with their shells, and three dasheng of urine from an uncircumcised boy. Decoct together to obtain one and a half dasheng. Divide into two doses. If rapid purgation occurs after the first dose, stop subsequent doses. Previously, this would have been considered true death, but thanks to the transmission, they survived. Fearing others might suffer similarly, I transmit this. Additionally, Shanjun (Fir Mushroom) originates from Yizhou, growing on old fir trees, resembling fungi. It is said to be bitter and slightly warm in nature. It treats heart and spleen qi pain as well as sudden heart pain. Harvest at any time.
