味甘，性温。主要功效是滋养精气、保护血液。大蓟主要用于治疗妇女赤白带下（阴道分泌物异常），安胎，止血（包括吐血和鼻出血），使人身体肥壮强健。五月采集。
大蓟就是虎蓟，小蓟就是猫蓟，它们的叶子都多刺，外形相似。在田野中非常多见，但医方用药中不再使用，这是因为它们被视为低贱的缘故。大蓟的根对治疗血证疗效显著，但也含有毒性。
【考证】大蓟和小蓟，叶子虽然相似，但药效有很大不同，两者均无毒，也不是所谓的虎蓟和猫蓟。大蓟生长在山谷中，其根部能治疗痈肿；小蓟生长在平原沼泽地带。两者都能破血散瘀，但小蓟不能消除肿胀。
味酸，无毒。主要治疗黄疸，心烦，气逆咳嗽，气血失调，肠胃中的突发高热，以及金创（金属利器造成的伤口）内部淤塞。长期服用可以补益中气，促进肌肉生长，使面色红润好看。又名昔邪，又名乌韭，又名垣嬴，又名天韭，又名鼠韭。生长在古老城墙的背阴处或屋顶上。三月三日采集，阴干。
医方中不常用，民间也少见有者。《离骚》中也提到昔邪，有人说这就是天蒜。
【考证】这就是古墙北面的青苔衣，生长在石头上的名叫昔邪，又名乌韭。江南地区少墙，所以陶弘景说少见。《神农本草经》记载：长在屋上的名叫屋游，列在下品，形状都相似，疗效大致相同。《名医别录》说：主治暴风口噤（突然发作的口眼歪斜或牙关紧闭），金疮，用酒浸泡后服用有效。
味苦，微温，无毒。主要功效是用艾草灸治各种疾病，也可以熬制成煎剂，止住腹泻痢疾，吐血，下部（指前阴或肛门周围）恶疮，妇女漏下血色，通利阴气，生用。又名冰台，又名医草。生长在田野中。三月三日采集，晒干。制作煎剂时不要让药液见到风。
捣碎叶片用来灸治各种疾病，也能止住外伤出血。汁液还能杀死蛔虫。用醋煎煮叶片，治疗癣症效果很好。
【考证】《名医别录》说：艾草治疗脓血痢，水煮或制成丸散均可使用。
Sweet in taste, warm in nature. Primarily nourishes essence (Jing) and preserves blood. Da Ji (Cirsium japonicum) is mainly used to treat leukorrhea (red and white vaginal discharge) in women, calms the fetus, stops hematemesis (vomiting blood) and epistaxis (nosebleed), and makes the person robust and healthy. Harvested in May.
Da Ji is Hu Ji (Tiger Thistle), Xiao Ji is Mao Ji (Cat Thistle); their leaves are both thorny and similar in appearance. They are abundant in fields, but no longer used in medical prescriptions due to their perceived low status. The root of Da Ji has significant effects on treating blood disorders but is also toxic.
[Verification] Da Ji and Xiao Ji have similar leaves but distinct efficacies; neither is toxic, nor are they Tiger or Cat Thistles. Da Ji grows in mountain valleys, and its root treats carbuncles and swellings; Xiao Ji grows in plains and marshes. Both can break up blood stasis, but Xiao Ji cannot reduce swelling.
Sour in taste, non-toxic. Primarily treats jaundice, restlessness, cough with qi rebellion, blood and qi disorders, sudden high heat in the stomach and intestines, and internal blockage from metal wounds.

Grows in the shade of ancient walls or on roofs. Harvested on the third day of the third lunar month, dried in the shade.

[Verification] This refers to the green moss growing on the north side of old walls; those growing on stones are named Xi Xie, also known as Wu Jiu. There are few walls in Jiangnan, so Tao Hongjing stated they were rarely seen. "Shen Nong Ben Cao Jing" records: those growing on roofs are named Wu You, listed in the Lower Class; their shapes are similar, and their therapeutic effects are roughly the same. "Ming Yi Bie Lu" states: it treats sudden facial paralysis or lockjaw, metal wounds, and is effective when taken after soaking in wine.
Bitter in taste, slightly warm, non-toxic. Primarily used for moxibustion to treat various diseases, can be made into a decoction, stops dysentery, hematemesis, sores in the lower region (genital/anal area), uterine bleeding, benefits the yin qi, and is used raw. Also known as Bing Tai and Yi Cao. Grows in fields. Harvested on the third day of the third lunar month, sun-dried. When making decoctions, do not let the liquid be exposed to wind.
Crushed leaves are used for moxibustion to treat various diseases and can also stop traumatic bleeding. The juice kills roundworms. Leaves boiled in vinegar are very effective for treating tinea.
[Verification] "Ming Yi Bie Lu" states: Ai Ye (Artemisia argyi) treats purulent bloody dysentery; it can be used by boiling in water or making into pills and powders.
