苍术性温，味甘、辛，气味轻薄而味道浓厚，无毒，药性既能上升也能下降，属于阳药。它归入足阳明胃经和足太阴脾经。能消除痰结形成的窠囊，去除胸中的狭窄感。治疗身体和面部的游风（游走性的风邪），缓解因风眩引起的头痛效果非常显著。能抵御山间的岚气瘴气，对抗时行疫病尤为灵验。能温暖胃部、安胎，宽畅中焦、增进食欲，驱除痰癖和气块，停止心腹部的胀满疼痛，其功效与白术相似。但在补益中气、除湿方面，力量不如白术；而在宽中发汗方面，功效则超过白术。如果用黄柏、牛膝、石膏等具有下行作用的药物作为引导，则可以清除下部的湿痰。如果用甘草、陈皮、厚朴等药物作为引导，则可以清除中焦的湿证，并平抑胃中过盛之气。如果用葱白、麻黄、杏仁等药物作为引导，则可以清除从肌肉层到皮肤表层的邪气。总的来说，有邪气的患者适宜使用，没有邪气的患者禁忌使用。庸医不分虚实，以及对于七情引起的气闷，一概使用白术是错误的。古人记载腹部狭窄感必须用苍术，医生们只是背诵这句话而不考察其背后的道理。因为苍术是辛散的药物，必须有湿症和实邪的患者，方才可以使用，难道是不分虚实就一概使用吗？况且如果是虚闷的患者使用它，就会耗损气血，燥化津液，导致虚火更加妄动，从而使闷塞感更加严重。炮制方法：用米泔水浸泡在铜器中，放置在月光下浸泡以去除黄油，洗净后晒干，再浸泡再晒干，如此经过三个夜晚，用清水漂洗后晒干，大约剩下五斤净药材。再用紫桑椹一斗、好醋一壶、盐四两，与苍术拌匀浸泡，晒至汁液干尽，然后蒸制，一晒一蒸，如此重复三次。又用大草半斤煎汁去渣，加入蜂蜜四两，洒润后蒸晒共九次，得到净苍术一斤。加入白茯苓四两、黄芩三两、当归四两、白术三两、神曲四两、秋石四两，用大甘草五两煎汁，加入竹沥和姜汁，将神曲打糊制成丸药，饮酒、白水或米饮送服均可，名为“五合丸”。能够健运脾胃，消除痰涎，助益精神，强壮身体。
Cangzhu (Atractylodis Rhizoma) is warm in nature, sweet and pungent in flavor, with a light qi and strong taste. It is non-toxic, capable of ascending and descending, and belongs to the Yang category. It enters the Foot-Yangming Stomach Meridian and the Foot-Taiyin Spleen Meridian. It resolves phlegm nodules and cysts, and relieves the sensation of tightness in the chest. It treats wandering wind affecting the body and face (Youfeng), and rapidly alleviates headache caused by wind-induced vertigo. It repels mountainous miasma and pestilential qi, proving particularly effective against seasonal epidemics. It warms the stomach, calms the fetus, expands the middle jiao, promotes appetite, drives out phlegm stasis and qi masses, stops abdominal distension and pain, and shares similar functions with Baizhu (Atractylodis Macrocephalae Rhizoma). However, its strength in tonifying the middle and drying dampness is inferior to Baizhu, whereas its efficacy in expanding the middle and inducing sweating surpasses that of Baizhu. When guided by downward-draining herbs such as Huangbai (Phellodendri Cortex), Niuxi (Achyranthis Bidentatae Radix), and Shigao (Gypsum Fibrosum), it clears damp-phlegm from the lower jiao. When guided by Gancao (Glycyrrhizae Radix et Rhizoma), Chenpi (Citri Reticulatae Pericarpium), and Houpo (Magnoliae Officinalis Cortex), it clears dampness from the middle jiao and pacifies excess qi in the stomach. When guided by Congbai (Allii Fistulosi Bulbus), Mahuang (Ephedrae Herba), and Xingren (Armeniacae Semen Amarum), it expels pathogens from the muscle layer to the skin surface. Generally, it is suitable for patients with pathogenic factors but contraindicated for those without. Incompetent physicians err by indiscriminately using Baizhu for both deficiency and excess patterns, as well as for qi stagnation caused by the seven emotions. Ancients recorded that abdominal tightness requires Cangzhu; however, practitioners merely recite this without examining the rationale. Cangzhu is a pungent and dispersing agent, applicable only when dampness and excess pathogens are present. Is it appropriate to use it indiscriminately regardless of deficiency or excess? Moreover, if used for deficiency-related stagnation, it depletes qi and blood, dries up fluids, agitates deficient fire further, and exacerbates the sensation of oppression.
Preparation method: Soak in rice washing water in a copper vessel, place under moonlight to remove yellow oil, wash clean, and sun-dry. Repeat soaking and drying for three nights. Rinse with clear water, wash clean, and sun-dry until approximately five jin of clean herb remains. Mix with one dou of Zisangshen (Mori Fructus), one pot of good vinegar, and four liang of salt. Soak, sun-dry until juice is exhausted, then steam. Repeat the cycle of sun-drying and steaming three times. Decoct Banjiacao (likely referring to a specific local herb, contextually "Da Cao") half a jin, strain, add four liang of honey, moisten, steam, and sun-dry nine times. This yields one jin of processed Cangzhu. Add four liang of Baifuling (Poria), three liang of Huangqin (Scutellariae Radix), four liang of Danggui (Angelicae Sinensis Radix), three liang of Baizhu, four liang of Shenqu (Massa Medicata Fermentata), and four liang of Qiushi (Lithii Carbonas). Decoct five liang of Da Gancao (Glycyrrhizae Radix et Rhizoma), add Zhuli (Bambusae Sap) and Jiangzhi (Zingiberis Recens Juice). Use Shenqu paste to bind into pills. Take with wine, plain water, or rice drink. This formula is named Wuhe Wan (Five-Harmony Pill). It strengthens the spleen and stomach, eliminates phlegm and saliva, boosts spirit, and strengthens the body.
