[Names] Liuyueling (sound like "ling", from *Tujing Bencao*), Liuyuanshuang (from *Bencao Gangmu*), Lvdouqing (from *Tujing Bencao*), Shelan.
Li Shizhen said: This herb has a cold nature, hence the names Ling, Shuang, and Lv dou.
[Collection and Explanation] Su Song said: Qujiecao grows in Yinzhou. Seedlings emerge in April; the stem is square-shaped, green, and jointed.

(Song Dynasty *Tujing Bencao*)
[Names] Xiannvao (from *Tujing Bencao*), Dingshencao.
Su Song said: Lichuncao grows in the valleys of Tan Mountain, which is located in the boundary of Gaomi. In Huaiyang Commandery, Sichuan (Shuchuan), Qiao Commandery, and Runan Commandery in Henan, it is called Longqiancao. In Hebei near the mountains, such as Ye Commandery and Ji Commandery, it is called Conglan'ai. Zitu Mountain in Shangdang also produces it, named Dingshencao or Xiannvao. It is now found everywhere. It is very effective for treating Jaundice (Huangdan), though people do not know this.
Li Shizhen said: This herb has remarkable efficacy, but its shape is not recorded. The current Poppy (*Yangsuxiao*, *Papaveris Somniferi Fructus*) is also called Lichuncao, and Jiuxiansizi is also called Xiannvjiao. They share the same name but are likely different substances. Further investigation is needed to confirm.
Flowers and Roots
[Flavor and Nature] Sweet, slightly warm, non-toxic.
[Indications] Treats Jaundice and Yellow Dan (Su Song).
[Innovation/Explanation] Su Song said: During the Tianbao era of the Tang Dynasty, Yang Zhengjin from Shuchuan Commandery presented a prescription, which was effective when used by famous physicians. The prescription states: Lichuncao treats heat injury caused by seasonal pathogens that transforms into Jaundice, characterized by high fever throughout the body, yellow-red urine, eyes appearing golden, dark blue-black complexion, qi pain in the heart region, abdominal pain like stabbing, dizziness and vertigo, accompanied by mass-like qi accumulation under the ribs, and jaundice, etc. Clinical experience confirms its efficacy. The drug is harvested during the three spring months, dried in the shade to one sheng, and pounded into a powder. Every morning at dawn on an empty stomach, take three fangcunbi (a measure roughly equivalent to a square inch) and mix with one lamp of raw sesame oil, taken all at once. Take once daily, resume after five days, until the desired effect is achieved. For the root's treatment of jaundice, extract one lamp of juice and take it all at once on an empty stomach. Soon after, there will be two or three bowel movements, and the disease will immediately cease. If one dose does not fully cure, administer another dose after seven days for permanent recovery. Avoid alcohol, wheat products, pork, fish, garlic, starches, and dairy products.
