《神农本草经》称其为“山蓟”。
味苦、辛，性温，无毒。产于茅山的苍术，味甘、形体瘦小且多毛，品质最佳。产于吴郡各山的苍术，品质次之。产于楚地的大块苍术，气味辛烈且燥性强，品质最差。炮制方法：用糯米泔水浸泡，刮去外皮，切成片，与芝麻同炒或麻油炒至通黄，去掉焦黑的末屑。或者去皮、切片，用蜜水拌匀，在饭上蒸熟使用。另外，白露节气后，用泔水洗净，放置在屋顶晒露一个月，称为“神术”。
【发明】苍术气味辛烈，性质温而燥。药势可升可降，能直接入各条经脉，疏泄阳明经的湿气，从而安定太阴脾脏，辟除时行疫疠的恶气。因为经过泔水浸泡和炒制，所以能去除上部湿气并发汗，这与白术止汗的作用不同，腹部感觉狭窄紧迫的患者需要服用它。《神农本草经》治疗风寒湿痹、肌肉坏死、痉挛、黄疸等病症，主要是取其药性专一于开泄腠理（皮肤毛孔），因此能发汗以祛除风寒湿气，祛除湿邪以消除肌肉坏死、痉挛和黄疸，降气以消除痰饮、食积和癖块。又能总解各种郁结，配合香附等行气药物，降气速度最快，一升一降则郁结消散而气机平和。遗精不禁、淋浊不止、腰背酸痛，使用苍术可以收敛脾津，因为津液生于谷气之中。与黄柏配伍组成二妙散，治疗下部湿热引起的肿痛。另外，单用苍术一味，用麻油炮制后研为粉末，煮大枣肉制成丸剂，治疗胁下停饮。许叔微患停饮病三十年，起初是因为年轻时夜间坐着写文章，身体向左倾斜伏在几案上，导致饮食多坠向左侧，饮酒停止时，从左侧发出声响，胁痛、食欲减退、胃中嘈杂，喝半杯酒就停止，没过几天必定呕吐酸水，夏季左半身完全没有汗，服用雄黄、附子、矾石、牵牛子、甘遂、大戟等药物都无效，自己揣测体内必有像囊袋中有窝臼一样的停饮之处，不填满低洼处就不流动，于是停用所有其他药物，只服用上述丸药三个月，疾病痊愈。夏季出汗遍及全身，在灯光下能看清细小的字，这都是苍术的功效。然而，只有原本体质肥胖多湿的人适宜服用，如果形体消瘦且内火旺盛者禁用。那种已经经过露制处理的神术，将燥性转为清润，用来发散上部头风、痰湿等各种病症，所以治疗时行头痛有神术汤，这是得益于炮制方法的奥妙。
*Shennong Bencao Jing* (Classic of Materia Medica) refers to it as "Shanji" (Mountain Thistle).
Bitter, acrid, warm, non-toxic. Cangzhu produced in Maoshan has a sweet taste, slender shape, and abundant hairs; it is of the best quality. Cangzhu produced in various mountains of Wu Commandery is of secondary quality. Large pieces of Cangzhu from Chu region, which are acrid, strong, and dry in nature, are of inferior quality. Processing method: Soak in rice washing water, scrape off the skin, slice, stir-fry with sesame seeds or sesame oil until thoroughly yellow, then remove burnt residues. Alternatively, remove skin, slice, mix with honey water, and steam over rice. Furthermore, after the White Dew solar term, wash cleanly with rice washing water, place on the roof to expose to dew for one month; this is called "Shenshu" (Divine Atractylodes).
*Shennong Bencao Jing* states it treats Wind-Cold-Damp Bi syndrome, necrotic muscle, spasms, and jaundice.
[Invention] Cangzhu is acrid and strong, with a warm and drying nature. Its action can ascend and descend, entering all meridians directly. It drains Dampness from the Yangming meridian, thereby stabilizing the Taiyin spleen, and expels malignant qi of seasonal epidemics. Due to soaking in rice washing water and frying, it can eliminate upper-body Dampness and induce sweating. This differs from Baizhu (Atractylopsis Macrocephala Rhizome), which stops sweating; thus, patients experiencing a sensation of tightness in the abdomen require it. *Shennong Bencao Jing* treats conditions such as Wind-Cold-Damp Bi, necrotic muscle, spasms, and jaundice, primarily relying on its specific property to open the Couli (skin pores). Therefore, it induces sweating to expel Wind-Cold-Damp pathogens, removes Dampness to eliminate necrotic muscle, spasms, and jaundice, descends Qi to resolve phlegm-fluids, food stagnation, and Pi masses. It can also resolve various types of Qi stagnation. When combined with Xiangfu (Cyperus Rotundus Rhizome) and other Qi-moving herbs, it descends Qi most rapidly; the ascending and descending actions disperse stagnation and calm Qi. For involuntary seminal emission, continuous stranguria and turbid urine, and soreness and pain in the waist and back, Cangzhu is used to consolidate Spleen Jin (fluids), as fluids are generated from Guqi (Grain Qi). Combined with Huangbai (Phellodendri Cortex) to form ErMiao San (Two Marvels Powder), it treats painful swelling caused by lower-body Damp-Heat. Additionally, using a single herb of Cangzhu, processed with sesame oil into powder, mixed with boiled jujube flesh into pills, treats Yin accumulation under the hypochondrium. Xu Shuwei suffered from Yin accumulation for thirty years. Initially, because he sat writing at night in his youth, leaning leftward on his desk, food and drink tended to settle on the left side. When drinking stopped, sounds were heard from the left; he experienced hypochondriac pain, reduced appetite, and gastric discomfort. After half a cup of wine, he would stop drinking, and within a few days, he would vomit sour fluid. In summer, there was absolutely no sweat on the left half of his body. He took Xionghuang (Realgar), Fuzi (Aconiti Lateralis Radix Praeparata), Fanshi (Alumen), Qianniu Zi (Pharbitidis Semen), Gansui (Kansui Radix), and Daye (Euphorbiae Pekinensis Radix), but none were effective. He deduced that there must be a reservoir-like cavity in his body holding fluid, similar to a hollow in the ground that does not flow until filled. Thus, he discontinued all other medicines and took the aforementioned pills for three months, resulting in the cure of his disease. In summer, sweating occurred throughout the body, and he could read fine print under lamplight; these effects were due to the power of Cangzhu. However, it is suitable only for those constitutionally obese and prone to Dampness; it is strictly contraindicated for those who are thin and prone to internal Fire. The "Shenshu" that has been processed by exposure to dew transforms its drying nature into clarity. It is used to dissipate upper-body Head Wind, Phlegm, and Dampness syndromes. Therefore, for epidemic headache, ShenZhu Tang (Divine Atractylodes Decoction) is employed, demonstrating the subtlety of processing methods.
