苍耳，又名卷耳。各地都有生长。茎高四到五尺，表面有黑色斑点。叶子形状像葵菜，边缘呈波浪状皱缩。七八月份开出细小的白色花朵，结出的果实像耳饰一样，外壳坚韧，密布刺毛，中间包含两粒种子，形状非常像人的肾脏。
苍耳子
味甘、苦，性温。主治各种风气，能填补骨髓，温暖腰膝。治疗头部受寒引起的疼痛，风湿引起的全身及四肢关节拘挛疼痛，以及久治不愈的气滞症状。将苍耳子炒香后浸泡在酒中服用，可以祛风补益。（李时珍记载）对于鼻渊（鼻窦炎）流涕，可将苍耳子炒熟研成粉末，每次用白开水冲服一钱或二钱。
苍耳茎叶
气味苦、辛，性微寒，有小毒。善于通达头顶并连接脑部。主治大风癫疾、头部风湿痹痛、毒邪深入骨髓的风毒。夏季采集并晒干研末，用水送服一匕量；冬季用酒送服，或者制成丸药，每次服用二三十丸，每日三次。若病症表现为类似疥疮且流脓水，或者皮肤斑驳粗糙、脱屑，则肌肤会变得如凝固的油脂般光滑细腻。（此处缺作者名）将其与腊月猪脂混合，外敷于疔肿处，可拔出病根。具有补暖、祛风、驻颜的功效。治疗皮肤风邪，使肌肤清爽洁净。使用苍耳的根、茎、叶、果实，洗净后阴干，烧成灰后用热水淋滤。连续煎煮两次，水分蒸发时随时添加补充，保持不间断加热一整日，直到析出霜状物，装入干燥的瓷瓶中保存。早晚各用酒送服二匙，可治头晕。将苍耳叶晒干研末，每次服用一钱，用酒调服，每日三次。如果引起呕吐，则改为制成梧桐子大小的蜜丸，每次服用适量。针对妇人血风攻脑导致的头晕目眩、昏厥倒地不省人事，取苍耳草嫩心，阴干研末，用酒送服一钱，效果显著。
治疗痈疽、发背、肿毒、疔疮、无头恶疮、各种风痒疮、杖疮、牙痛、喉痹等症。在五月五日采集苍耳，洗净晒干，切碎。用五口大锅，加水煮烂，过滤去除粗渣，再用布绢细滤，倒入干净的锅中，用火熬制成稠膏，搅拌成膏状，装入新罐密封保存。每次取适量外敷即可痊愈。牙痛敷在牙齿上，喉痹敷在舌上，或者含在口中，均有疗效。每日用酒送服一匙，效果极佳。对于翻花恶疮（一种增生性疮疡），肉质如饭粒，破溃后出血，随即又长出反突的组织，取汁液服用三合，并涂抹患处，每日两次。一切危重的疔肿，用苍耳根叶捣碎，加入小儿尿液绞汁，每日三次服用，拔除病根非常有效。苍耳丸：在端午节中午，采集苍耳叶洗净，晒干研末，用炼蜜制成梧桐子大小的丸药，每次五十丸，每日三次。如果身体有风邪停留的部位，会排出如麻豆或粟米大小的颗粒，这是风毒排出的表现。七月七日、九月九日也可以采用此法采收。
〔论〕 苍耳善于通达头顶并连接脑部，因此能清除骨髓中的毒邪，而《日华子本草》又说它能填补骨髓，大概是因为它能通达至阴之中的阳气，使静止的风邪得以转化，极巅之湿痹得以疏通，成为生命的根本。它自下而上通达，郁结之气得以疏散，其味苦微辛，果实……（原文此处断句混乱，推测意为果实具此功效）。
服用苍耳者，忌食猪肉和米泔水。
Cang'er (Xanthii Fructus), also known as Juan'er. It is found everywhere. The stem is four to five chi high, with black spots. The leaves resemble those of Malva verticillata (kui), with wavy margins. In the seventh and eighth months, it produces small white flowers. The fruit resembles an ear ornament; the outer shell is tough and densely covered with prickles, containing two seeds inside that closely resemble human kidneys.
Cang'erzi (Xanthii Fructus)
Taste: sweet, bitter. Temperature: warm. Indications: treats all types of wind-pathogens, fills the marrow, warms the waist and knees. Treats cold-pain in the head, rheumatic bi-syndrome causing stiffness and pain in the limbs, and chronic qi stagnation. Stir-fry until fragrant, soak in wine, and take orally to dispel wind and tonify deficiency. (Recorded by Li Shizhen) For Biyuan (nasal sinusitis) with runny nose, stir-fry Cang'erzi, grind into powder, and take one or two qian each time with plain boiled water.
Cang'er Jingye (Stems and Leaves of Xanthium strumarium)
Odor and taste: bitter, acrid. Temperature: slightly cold. Toxicity: slightly toxic. Properties: excels at penetrating the vertex and connecting to the brain. Indications: treats severe wind-epilepsy, wind-damp bi-syndrome of the head, toxins deep in the bone marrow, and wind-toxins. In summer, harvest and sun-dry, grind into powder, and take one bi (spoonful) with water; in winter, take with wine, or make into pills. Take 20-30 pills each time, three times a day. If symptoms manifest as sores resembling scabies with exudate, or mottled, rough skin with peeling, the muscle will become smooth like congealed fat. (Author missing) Mix with lard from the twelfth lunar month, apply externally to ding-swelling (carbuncles/furuncles) to extract the root. It has warming, wind-dispelling, and youth-preserving effects. Treats skin wind-pathogens, keeping the skin clean and pure. Use the roots, stems, leaves, and fruits of Cang'er. Wash and shade-dry, burn to ash, and leach with hot water. Boil twice consecutively. As the liquid reduces, replenish continuously without stopping the fire for a full day, until frost-like crystals precipitate. Store in a dry porcelain jar. Take two spoons with wine morning and evening to treat dizziness. Sun-dry Cang'er leaves, grind into powder, take one qian each time, mixed with wine, three times a day. If vomiting occurs, prepare honey pills the size of Sophora japonica seeds. For women suffering from blood-wind attacking the brain, causing dizziness, fainting, and collapse, take the tender hearts of Cang'er grass, shade-dry, grind into powder, and take one qian with wine; this is highly effective.
Treats carbuncles, back abscesses, swelling and toxicity, ding-sores, headless malignant sores, all types of wind-itch sores, beating injuries, toothache, and throat obstruction (houbi). Harvest Cang'er on the fifth day of the fifth lunar month. Wash clean and sun-dry, cut finely. Use five large pots, add water, boil until soft, filter out coarse residues, then filter again through cloth and silk. Pour into a clean pot and simmer over fire until thick, stirring into a paste. Store in a new jar and seal. Apply externally to affected areas for cure. For toothache, apply to the teeth; for throat obstruction, apply to the tongue, or hold in the mouth; both are effective. Take one spoon with wine daily; extremely effective. For fanhua malignant sores (fungating ulcers) where flesh resembles rice grains, bleeding upon rupture, and subsequent protrusion, take three he of the juice and apply externally, twice a day. For critical ding-swelling, crush Cang'er roots and leaves, mix with children's urine, squeeze out the juice, and take three times a day; extracting the root is very effective. Cang'er Wan (Pills): At noon on the Dragon Boat Festival, harvest Cang'er leaves, wash clean, sun-dry, and grind into powder. Make pills with refined honey, size of Sophora japonica seeds. Take 50 pills each time, three times a day. If wind pathogens reside in the body, they will be expelled as particles resembling hemp seeds or millet, indicating the exit of wind-toxins. Harvesting can also be done on the seventh day of the seventh lunar month or the ninth day of the ninth lunar month.
[Discussion] Cang'er excels at penetrating the vertex and connecting to the brain, thus it can eliminate toxins in the bone marrow. Ri Hua Zi Ben Cao also states it fills the marrow, likely because it can reach the yang within the extreme yin, transforming static wind, resolving damp-bi at the vertex, becoming the root of life, ascending from below, dispersing stagnation, with its taste being bitter and slightly acrid, and its fruit... [Text fragment].
Those taking Cang'er should avoid pork and rice washing water.
[Processing] When using the fruit, steam or stir-fry until cooked, crush, and remove the prickles before use. Use stems and leaves according to the prescription.
