又名千金草。夏初时节开始发芽，多生长在台阶旁或道路左侧，叶片像韭菜一样但质地柔软，六七月间长出茎秆，高度约一尺，花朵呈三叉状。其茎干细弱且坚韧，拔起时不易折断，最难清除，因此得名“牛筋”。
根部入药，可治疗脱力黄（因过度劳累导致的萎黄病）、劳力伤（因体力劳动受损）以及痨瘵（肺结核等慢性消耗性疾病）。取此草连根洗净泥土，放入乌骨雌鸡的腹内蒸熟，去掉草药后食用鸡肉。效果良好。《百草镜》记载：能行血并增强体力，归入肝经。
按语：《湖州府志》记载：南天烛，也名叫牛筋草，又名叫乌饭草。这与本文所述名称相同但实物不同。
又名翠云草、孔雀花、神锦花、鹤翕草。凤尾草独茎成瓣，细叶聚簇，叶上有翠绿色的斑点。《百花镜》记载：翠云草没有直立的梗，适宜倒挂或平铺在地面上，因为它的叶子青绿苍翠，层层叠叠且皱缩，宛如翠玉饰片和云彩翘起，因此得名。但它只有颜色而没有花香，不是芸香。
它的根遇到土壤就能生长，见到阳光就会枯萎，本性最喜欢阴湿环境。《粤志》记载：孔雀花可以用来避暑。
汪连仕《采药书》记载：翠云草，一名翠翕草。即矮脚凤毛。治疗痔漏，配合胡桃叶煎水清洗（出自王连仕方）。治疗吐血有神奇疗效。《百草镜》记载：女子吐血，用翠云草三钱，水煎服用。
嘉庆癸亥年，我寓居在西溪吴氏家中，次子十五岁，忽然腹部和背部患起红色肿块，蔓延至腰部如腰带环绕，有人说是蛇缠疮，用药无效，两三天后肿块消退，随即化脓严重，再用如意金黄散外敷，也不见效。第二天，疮口旁边又出现红晕，范围更加扩大。有一位老妇人教我用开屏凤毛，也就是翠云草。捣碎取汁涂抹患处，一夜之间立刻消散。这种草解火毒如此神效，不仅治疗吐血有奇效。
又名老鹳红。水鸡冠。立夏之后生苗，一根茎直立向上，茎红色叶尖，细长狭小，八月结实，果实六角形，五月采收。
Also known as Qianjin Cao (Thousand Gold Grass). It sprouts in early summer, mostly growing by the steps or on the left side of roads. The leaves resemble those of leeks but are soft. In June and July, stems emerge, reaching a height of about one chi (approx. 33 cm), with flowers branching into three parts. The stems are weak yet tough, difficult to break when pulled up, and hardest to eradicate, hence the name Niujin Cao (Ox Tendon Grass).
The roots are used in medicine to treat Tuoli Huang (wasting-yellow syndrome due to overexertion), Laolishang (injury from labor), and Zhai (tuberculosis or chronic consumptive diseases). Take this grass with roots, clean off the mud thoroughly, place it inside the abdomen of a black-bone hen, steam until cooked, remove the grass, and eat the chicken. This is effective. *Baicao Jing* (Mirror of Hundred Herbs): Promotes blood circulation and increases strength; enters the Liver meridian.
Note: *Huzhou Fuzhi* (Gazetteer of Huzhou Prefecture) records: Nantian Zhu, also named Niujin Cao, and also named Wufan Cao (Black Rice Grass). Although the names are the same, the substances are different.
Also known as Cuiyun Cao (Emerald Cloud Grass), Kongque Hua (Peony Flower), Shenjin Hua (Divine Brocade Flower), Hexi Cao (Crane Wing Grass). Fengwei Cao (Phoenix Tail Grass) has a single stem forming petals, with fine leaves clustered together, bearing emerald spots on the leaves. *Baihua Jing* (Mirror of Hundred Flowers) records: Cuiyun Cao lacks straight stalks; it is suitable for hanging upside down or spreading flat on the ground. Because its leaves are green and verdant, layered and crinkled, resembling emerald ornaments and rising clouds, it is so named. However, it has color but no floral fragrance, and is not Yunxiang (Rue).
Its roots take root upon touching soil and wither upon exposure to sunlight; its nature prefers shade and moisture. *Yuezhi* (Records of Yue) states: Kongque Hua can be used to avoid summer heat.
Wang Lianshi's *Caoyao Shu* (Book of Herb Gathering) records: Cuiyun Cao, also named Cuixi Cao. Also known as Aijiao Fengmao (Short-legged Phoenix Feather). Treats hemorrhoids and fistulas by decocting with Walnut Leaves for washing (from Wang Lianshi's formula). Has miraculous effects for treating hemoptysis. *Baicao Jing*: For women with hemoptysis, use 3 qian (approx. 11-12 g) of Cuiyun Cao, decocted in water and taken orally.
In the Guihai year of the Jiaqing reign, I resided at the Wu family home in Xixi. My second son, aged fifteen, suddenly developed red nodules on his abdomen and back, spreading around his waist like a belt. Some called it Shechuan Chuang (Snake-wrapping sore). Previous treatments were ineffective. After two or three days, the nodules subsided, but severe suppuration ensued. Applying Ruyi Jinhuang San (Ruyi Golden Yellow Powder) externally was also ineffective. The next day, a red halo appeared around the sore, expanding further. An old woman advised using Kaiping Fengmao (Opening Peacock Phoenix Feather), which is Cuiyun Cao. Crushed and juiced, applied topically, it disappeared completely overnight. This herb resolves Fire-Toxin so effectively, not only being miraculous for treating bleeding.
Also known as Laoguan Hong (Old Stork Red). Shuijiguan (Water Chicken Comb). Sprouts after Lixia (Start of Summer). One stem grows straight up; the stem is red, leaf tips sharp, long and narrow. Bears fruit in August, hexagonal in shape. Harvested in May.
Treats Fengbi (Wind-Bi syndrome/rheumatic pain) and traumatic injuries. Boil Sheep Liver and consume it to reduce Hongzhang (red obstruction/cloudiness in the eyes).
