多毛，茎亦无羽，根直下，更无旁枝，生则肉白皮黑，中有黑脉，日干则黑如玄参。用叶茎

味苦，性平，无毒。主治骨节发热，小腿沉重酸痛，头晕目眩且头顶沉重感，皮肤间邪风侵袭如被蜂刺针扎，皮肤出现鱼子般细小的突起，热疮、痈疽、痔疮，湿痹，能止风邪引起的咳嗽，并能促进乳汁下行。长期服用可使人身体轻盈，益气，明目，延缓衰老，可以煮食也可以晒干。又名漏芦，又名天荠，又名伏猪，又名飞轻，又名伏菟，又名飞雉，又名木禾。生于河内地区的川泽之中。正月采集根部，七月、八月采集花朵，阴干。（忌与乌大良同用，恶麻黄。）
陶隐居说：到处都有，极像苦（乌老切），只是叶子下附于茎，表面轻微隆起似箭羽，叶子多有刻缺，花为紫色。世俗方剂中几乎不用它，而道家服用其枝茎，可得长生，又用于神枕方。如今既然已有另外的漏芦，那么这就不是那个别名了。唐本注说：此药有两种：一种是陶弘景所证实的，生长在平泽中的。那些生长在山岗上的，叶子颇相似，但没有疏缺，而且多毛，茎也没有羽状特征，根直下，更没有旁枝，生时肉白皮黑，中间有黑脉，晒干后黑得像玄参。使用叶、茎及根，治疗疳蚀，杀虫，与平泽生长的同样有效。现在世俗将马蓟当作苦来作为漏芦，并不是正确的。臣禹锡等谨按蜀本图经说：叶子像苦，茎像软羽，紫花，种子毛白。现在各地平泽都有，五月、六月采集，晒干。药性论说：飞廉，使药，味苦、咸，有毒。主治留血。萧炳说：小儿疳痢，制成散剂，用浆水送下，效果显著。
雷公说：凡使用，不要用赤脂蔓，它与飞廉形状相似，只是赤脂蔓见酒色便如血色，可以辨别它。凡是修整处理，先刮去粗皮，捣碎，用苦酒拌一夜，到明天滤出，晒干，细捣后用之。千金翼：治疗疳积食滞导致的口齿及下部病变。飞廉蒿烧成灰捣筛，取两钱匕放在痛处，非常疼痛要忍耐；如果不痛，就不是疳病。下部虫如马尾大，相互缠绕出来无数。十天痊愈，二十天平复。
Taste bitter, nature neutral, non-toxic. Primarily treats heat in bone joints, heaviness and soreness in the shins, dizziness with a sensation of heaviness at the vertex, pathogenic wind invading the skin like bee stings or needle pricks, fish-egg-like small eruptions on the skin, hot sores, carbuncles, hemorrhoids, damp-bi syndrome, stops cough caused by pathogenic wind, and promotes lactation. Long-term consumption makes the body light, benefits qi, brightens the eyes, prevents aging; it can be boiled or dried. Also known as Loulu (Leontodon hispidus), Tianqi, Fuzhu, Feiqing, Futu, Feizhi, and Muhe. Grows in rivers and marshes of Henei. Roots are harvested in the first lunar month, flowers in the seventh and eighth months, and dried in shade. (Incompatible with Wudalian, adverse reaction with Mahuang.)
Tao Hongjing stated: It is found everywhere, resembling Ku (Wulaoqie), but its leaves attach to the stem underneath, the surface is slightly raised like arrow feathers, the leaves have many incisions, and the flowers are purple. It is rarely used in secular prescriptions, but Daoists consume its branches and stems for longevity, and it is also included in the Shen Zhen prescription. Since there is now another Loulu, this is not that alias. The Tang Ben Zhu noted: There are two types: one is what Tao verified, growing in flat marshes. Those growing on hillsides have similar leaves but lack incisions, are hairy, stems lack feather-like features, roots grow straight down without side branches, flesh is white and skin black when fresh, with black veins inside, turning black like Xuanshen when dried. Leaves, stems, and roots are used to treat gan erosion, kill parasites, and are effective just like those from flat marshes. Currently, people mistakenly use Maji (Cirsium japonicum) treated as Ku to serve as Loulu, which is incorrect. Chen Yuxi et al. consulted the Shu Ben Tu Jing stating: Leaves resemble Ku, stems resemble soft feathers, purple flowers, seeds with white hairs. It is present in flat marshes everywhere, harvested in the fifth and sixth months, and dried in the sun. Yao Xing Lun states: Feilian is an assistant drug, taste bitter and salty, toxic. Primarily treats retained blood. Xiao Bing stated: For pediatric gan dysentery, make into powder, administer with Jiangshui (fermented grain liquid), highly effective.
Lei Gong stated: When using, do not use Chizhiman, which resembles Feilian in shape; however, Chizhiman turns blood-red upon contact with wine, allowing for distinction. For processing, first scrape off the coarse skin, pound, mix with Kujiu (sour wine) overnight, strain the next morning, dry in the sun, and finely pound before use. Qianjin Yi: Treats gan accumulation food stagnation affecting oral teeth and lower parts. Feilianhao burned to ash and sifted, apply two qian bi (measurements) to the painful area; it causes severe pain, endure it; if no pain, it is not gan disease. Worms in the lower part are as large as horse tails, entangled and emerging in countless numbers. Cured in ten days, recovered in twenty days.
