莪术专门入肝经。其味辛、苦，性温。具有强力破除肝经气分瘀血的作用。
大抵人的气血平和安适，则气与血相通，血与气相互依附。
一旦有所偏颇，要么气盛而阻碍血行，要么血壅滞而导致气机郁结。
三棱气味苦平，既能于肝经血分中驱逐气滞；莪术气味辛温，又能于气分中逐散瘀血。
因此，凡是因气被血阻滞而出现积块疼痛不止、吐酸水、奔豚气、痞块、癖块、症瘕等病症的，必须使用这两味药来调治。（按压身体某处有应手感的是“症”，这是因伤食所得，假借实物成形的是“瘕”，这是因伤血所得，显露在肌肤表面可见的是“痞”，这是因伤气所得，结聚于隐蔽部位不可见的是“癖”，这是因积聚所得。五积之中，肝之积名为肥气，位于左胁下，形状像倒扣的杯子，有头有足，如同龟鳖之状；心之积名为伏梁，起于脐上，粗如手臂，向上延伸至心下；脾之积名为痞气，位于胃脘部，覆盖面积大如盘子；肺之积名为息贲，位于右胁下，形覆如大杯；肾之积名为奔豚，发作于少腹，向上至心下，有如小猪奔走之象，或上或下，也没有固定时间。《内经》说：对于大的积聚，可以使用有毒的药物攻伐。病势衰退大半时就应停止，过度攻伐会导致死亡。因此去除积滞，必须以甘温的药物调养。又说：体质强壮者，气机运行通畅则积滞自消；体质虚弱者，邪气留着而成疾病。张洁古说：壮年人无积滞，只有体虚之人会有积滞。所以养护正气，邪气自然除去。）从而使气从血中得以顺畅，而不致使闭结不通。
但是蓬术（莪术）虽然属于消磨积滞的药物，（血积适宜用桃仁、穿山甲、干漆、大黄、虻虫、蓬术、瓦楞子；痰积适宜用半夏、天南星、白术、枳实、礞石、硝石、风化硝、白芥子、海浮石、蛤粉；水积适宜用大戟、甘遂、荛花、芫花；酒积适宜用干葛、神曲、砂仁、豆蔻、黄连、干姜、甘遂、牵牛子；茶积适宜用姜黄、吴茱萸、花椒、生姜；癖积适宜用三棱、莪术、巴豆霜、大黄；肉积适宜用山楂、阿魏、硝石；蛊积适宜用雄黄、锡灰、槟榔、雷丸、芜荑、使君子、鹤虱；疟积适宜用桃仁、鳖甲、草果。）如果让体虚之人服用，最为危险。必须配合人参、白术等补益药物才为妙策。
个头较大的是广术。（苏颂说：这种药材极其坚硬难以捣碎。）用灰火煨透，趁热捣碎。或者用醋磨、酒磨，或者煮熟后使用。
(Within the category of aromatic herbs) Ezhu (Rhizoma Curcumae) can drain blood stasis from the Qi level of the Liver meridian.
Ezhu specifically enters the Liver meridian. Its flavor is acrid and bitter, and its nature is warm. It has the powerful function of breaking up blood stasis at the Qi level of the Liver meridian.
Generally speaking, when a person's Qi and Blood are harmonious and peaceful, Qi and Blood flow together, and Blood adheres to Qi.
Once there is any deviation, either excessive Qi will obstruct Blood flow, or stagnant Blood will cause Qi stagnation.
Sanleng (Rhizoma Sparganii) has a bitter and neutral flavor; it can expel Qi stagnation within the Blood level of the Liver meridian. Ezhu has an acrid and warm flavor; it can further disperse Blood stasis within the Qi level. Therefore, for conditions such as unrelenting pain from accumulations, acid regurgitation, running piglet syndrome (Ben Tun), epigastric fullness (Pi), hidden masses (Pi), and fixed or movable masses (Zheng Jia) caused by Qi being obstructed by Blood, these two herbs must be used for treatment. (Note: "Zheng" refers to masses that are palpable upon pressure, resulting from food injury and taking shape from physical substances; "Jia" refers to masses resulting from blood injury, visible on the skin surface; "Pi" refers to fullness resulting from Qi injury; "Pi" [hidden] refers to masses resulting from accumulation, located in hidden areas and invisible. Among the Five Accumulations: Liver accumulation is called Fei Qi, located under the left hypochondrium, shaped like an inverted cup with head and feet, resembling a turtle or tortoise; Heart accumulation is called Fu Liang, starting above the umbilicus, thick as an arm, extending up to below the heart; Spleen accumulation is called Pi Qi, located in the epigastrium, covering an area large as a plate; Lung accumulation is called Xi Ben, located under the right hypochondrium, shaped like a large inverted cup; Kidney accumulation is called Ben Tun, originating in the lower abdomen and extending up to below the heart, resembling the running of a piglet, moving up or down without fixed timing. The Classics state: For large accumulations, toxic drugs may be employed. Stop when the pathogenic factor has been reduced by more than half; over-treatment leads to death. Therefore, to remove accumulations, one must nourish with sweet and warm tonics. It is also said: In robust individuals, if Qi flows freely, the accumulation resolves itself; in weak individuals, the pathogen lingers and causes disease. Zhang Jiegu stated: Robust people do not have accumulations; only deficient individuals do. Thus, by nurturing righteousness (healthy Qi), evil naturally eliminates.) This allows Qi to flow smoothly from Blood, preventing closure and obstruction.
However, although Pengzhu (Ezhu) belongs to the category of herbs that dissipate accumulations, (For Blood accumulation, suitable herbs include Tao Ren, Shan Jia, Gan Qi, Da Huang, Meng Chong, Pengzhu, Wa Leng Zi; for Phlegm accumulation, Ban Xia, Nan Xing, Bai Zhu, Zhi Shi, Meng Shi, Xiao Shi, Feng Hua Xiao, Bai Jie Zi, Hai Shi, Ge Fen; for Water accumulation, Da Ji, Gan Sui, Yao Hua, Yuan Hua; for Wine accumulation, Gan Ge, Shen Qu, Sha Ren, Dou Kou, Huang Lian, Gan Jiang, Gan Sui, Qian Niu; for Tea accumulation, Jiang Huang, Zhu Yu, Jiao Jiang; for Hidden mass accumulation, San Leng, Ezhu, Ba Shuang, Da Huang; for Meat accumulation, Shan Zha, A Wei, Xiao Shi; for Gu accumulation, Xiong Huang, Xi Hui, Bing Lang, Lei Wan, Wu Yi, Shi Jun Zi, He Shi; for Malaria accumulation, Tao Ren, Bie Jia, Cao Guo.) if taken by deficient individuals, it is most dangerous. It is best to combine it with tonics such as Ren Shen and Bai Zhu.
The larger variety is known as Guangzhu. (Song states: This material is extremely hard and difficult to crush.) It should be roasted thoroughly in ash fire and crushed while hot. Alternatively, it can be ground with vinegar or wine, or used after boiling.
