(From *Bencao Shiyi* [Supplement to Materia Medica])
Su Song stated: It grows in the mountains and wilds of the South Sea, and is not found elsewhere. The vine winds around trees and plants, with small leaves. As stated in the *Nandu Fu* (Rhapsody on the Southern Capital), "Fengyan spreads over the Henggao," referring to this plant. Its taste is bitter, its nature is cold, and it is non-toxic. It primarily treats fever and rigidity in children, convulsions with alternating chills and fever, heat strangury (a syndrome characterized by painful and scanty urination), promotes diuresis, relieves irritability, and brightens the eyes; all are treated by decocting and drinking.

Li Shizhen stated: It primarily treats Sanxiao (three wasting-thirst syndromes characterized by polydipsia, polyphagia, and polyuria) and Wulin (five types of strangury: stone, qi, paste, labor, and blood strangury), descends phlegm, treats bloody and white dysentery in children, snake venom, miasma and stream toxins, and various sores and swellings; all are suitably treated by decocting and drinking.

Qianli Ji (From *Bencao Shiyi*)
[Correction] Merged into *Bencao Tujing*'s Qianliguang.
[Ji Jie (Collected Explanations)] Su Song stated: Qianli Ji is a vine growing beside roads and among hedges, with fine and dense leaves. It grows in Xuanzhou and Huzhou.
Su Song stated: Qianli Ji grows in Tiantai Mountain. Sprouts emerge in spring, and flowers appear in autumn. Locals harvest the flowers and leaves for eye medicines. Additionally, in Yinzhou, there is Qianliguang, growing in shallow mountains and by roadsides. The leaves resemble chrysanthemum leaves but are longer, with hairs on the underside. The stems and branches are round and green. Sprouts emerge in spring, yellow flowers appear in autumn, and it does not bear fruit. The stems and leaves are harvested for eye medicines, named Huanghua Yan. They are likely the same substance.
[Qi Wei (Flavor and Nature)] Bitter, neutral, slightly toxic. Su Song stated: Bitter, sweet, cold, non-toxic.
[Zhu Zhi (Main Indications)] Treats epidemic qi causing jaundice, malarial fevers, and gu poison; decocted juice is taken to induce vomiting or purgation. It can also be crushed and applied externally to treat snake and dog bites (Su Song). Decocted with Gancao (Licorice Root) and drunk to reduce fever and brighten the eyes, but not combined with other herbs (Su Song). Decocted with Xiaoqing (Small Green herb) to treat bloody dysentery with abdominal pain (Li Shizhen).
[Fu Fang (Attached Prescriptions)] One new prescription.
Lanxian Fengyan (Ulcerative Blepharitis due to Wind): Take Qianliguang grass, wrap it in bamboo husk leaves, bake until cooked, squeeze out the juice, and drip into the eyes. (From *Jingyan Liangfang*)

(From *Haiyao Bencao*)
[Correction] Transferred from the Wood category to this section.
[Shi Ming (Explanation of Names)] The tree is named Haiteng.
Li Shizhen stated: According to Guo Yigong's *Guangzhi*, it is produced in the cliffs of various mountains in Yuezhou, Ezhou, etc. The tree is named Haiteng. The flowers have stamens that scatter onto rocks; locals collect them and call them Shahuang. Those collected directly from the tree are light and exquisite, called Lahuang. People nowadays mistakenly call it Tonghuang, due to a phonetic error between "Tong" (copper) and "Teng" (vine). This is no different from collecting Shilei (stone tears/resin). Painters and alchemists use it occasionally.
Li Shizhen stated: The Tenghuang used by painters today is all refined through boiling and processing; licking it causes numbness in the tongue. According to Zhou Daguan's *Zhenlu Ji*, the country has Huahuang, which is resin. Foreigners cut the tree branches with knives to let the sap drip down, collecting it the following year. This differs slightly from Guo's description; it is unknown if they are the same substance?
[Qi Wei (Flavor and Nature)] Sour, astringent, toxic.
[Zhu Zhi (Main Indications)] Dental caries; applying it causes the tooth to fall out (Li Xun).
