（宋代《图经本草》）
【释名】六月凌（读音同“令”，出自《图经本草》）、六月霜（出自《本草纲目》）、绿豆青（出自《图经本草》）、蛇蓝。
李时珍说：这种草性质寒凉，所以有凌、霜、绿豆这些名字。
【集解】苏颂说：曲节草生长在筠州。四月长出苗，茎呈方形，颜色青绿且有节，叶子像刘寄奴但质地更青软，七月、八月开花像薄荷，结出的种子没有药用价值。五月、六月采集茎叶，阴干保存。
茎叶
【气味】味甘，性平，无毒。
【主治】治疗发背疮，消除痈肿，拔除毒邪。与甘草一起研成粉末，用米汤调服。
（宋代《图经本草》）
【释名】仙女蒿（出自《图经本草》）、定参草。
苏颂说：丽春草生长在檀山的山谷中，檀山位于高密地界。河南的淮阳郡、蜀川及谯郡、汝南郡等地，都叫它龙芊草。河北靠近山的邺郡、汲郡等地，都叫它丛兰艾。上党的紫团山也有生长，名叫定参草，又名仙女蒿。现在各地都有出产。它治疗黄疸的效果很好，但人们不知道这一点。
李时珍说：这种草有特殊功效，但没有记载其形状。现在的罂粟也叫丽春草，九仙子也叫仙女娇，与此同名，恐怕不是同一种东西。应当等待广泛查访确认。
花及根
【气味】味甘，微温，无毒。
【发明】苏颂说：唐天宝年间，蜀川郡杨正进献上方，名医使用都有效。他的方子说：丽春草治疗因时令患伤热，变成黄疸，全身壮热，小便黄赤，眼睛像金色，面部青黑，心口气痛，腹部疼痛如针刺，头晕欲倒，兼有胁下有瘕气，以及黄疸等症，经过验证有效。该药在春季三个月采集花朵，阴干一升，捣碎成散剂。每天清晨空腹取三方寸匕的量，和一盏生麻油一次性服用，每日一次，隔五天再服用，以见效为度。它的根部治疗黄疸，榨汁一盏，空腹一次性服用，不久就会腹泻两三行，疾病立即痊愈。一剂不能全愈，隔七天再服一剂，彻底治愈。忌食酒、面食、猪肉、鱼、蒜、粉状食物、奶酪等。
(Song Dynasty *Tujing Bencao*)
[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. The leaves resemble those of Liu Jinu (*Artemisia japonica*) but are greener and softer. It flowers in July and August, resembling Mint (*Bohe*, *Menthae Haplocalycis Herba*), but the seeds have no medicinal use. Harvest the stems and leaves in May and June, and dry them in the shade.
Stems and Leaves
[Flavor and Nature] Sweet, neutral, non-toxic.
[Indications] Treats Faback sores (Fabeichuang), dissipates carbuncles and swellings, and draws out toxins. Mix with Licorice Root (*Gancao*, *Glycyrrhizae Radix et Rhizoma*) into powder, and take mixed with rice water.
(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.
