荆湖南北、中州及二川等地都有生长。四月长出苗叶。叶子形状像茵陈。穗状花序像荆芥。花朵像水苏。但气味却截然不同。
有一种香薷，叶片大且茎呈方形；另一种叶片最细，仅高几寸，香气反而更胜一筹，这就是石香薷。在九月开花结穗时采收效果最好。
味道辛，气微温，作用趋势既可上升也可下降，属阳。归足阳明胃经、足太阴脾经和手少阴心经。主要功效是疏散肺部的邪气，帮助肺部进行清肃与化生，恢复清气。能治疗霍乱引起的腹痛、呕吐和下利，消散水肿，通利小便，止住吐血和鼻衄，治疗中暑内热。具有从上到下全面调理的功效，治疗水肿非常迅速。肺部得到它，则清肃化生的功能运行，热气自然下降。（丹溪）对于胀病也有疗效。（又）香薷饮，是治疗暑病的要药。
如果因饮食不节制，劳累过度耗伤正气而感受暑邪，出现大热、大渴、汗出如雨、烦躁、气喘急促等症状，应当使用香薷益气，以及人参白虎汤之类的方剂来泻火益元。（李时珍/濒湖）香薷的功效在于治疗水湿之病。例如有人大便溏泄，小便短少，诊察其脉象沉而大，沉脉主里，稍加安定后，再用胃苓丸（苍术丸），两天后小便通畅，肿胀消退，调理数日后完全康复。由此可见古人的方剂都有深刻的道理，而香薷这味药在治疗方面有奇效。（又）香薷治疗暑病，世人尚未探究其所以然。大概暑气流行称为“暑淫”，肺金受到邪气侵袭称为“暑伤于肺”。肺主通调水道，向下输注到膀胱。如果精气不能正常游溢上行，导致水道不通，香薷的作用就在于调节精气。经文说：“金郁则泄之”，解表利小便就是其中的含义。如果玄府（汗孔）闭塞而幽门（指体内津液代谢的关键通道或下焦门户）闭合，就会使肺金受郁。开启玄府，也就启发了幽门的开阖，因此它的功力还在于玄府。经文说：“藏真高于肺，以行营卫阴阳之气”，香薷能在脉中整理营气，在脉外肃清卫气。它舍弃了高源之脏（肺）的真气实滞，从而治疗吐下及消散水肿。如果五水突然聚集成肿，审察霍乱暑气为本，本风亦可，本寒本湿亦可，本虚本实亦可，本营卫不调亦是如此，那么香薷的功力不仅限于针对逆乱暑气而成的病症。观易简主治四时伤寒不正之气，惠治鼻衄不止，《外台秘要》治疗吐血如涌泉，《永类钤方》等记载也证实了这一点。（之颐）郁金与香薷功效略有异同。香薷偏重于卫气和阳气，郁金偏重于营气和阴气。它能宣通形藏，弥合元府，敷布幽门。治疗水肿以香薷为君药，配合参、术、木瓜、茯苓、橘皮、白芍、车前子效果良好。治疗暑病的香薷饮，有十味药的版本（如有咳嗽者，去掉人参、白术；有用六味药的版本；有加黄连的版本）。取香薷一斤，水一斗，熬至极烂，去渣，再熬成膏。简易用法是捣筛成末，用酒调服，热服取汗。这是各因其势而利导之，并非不法度。
[论] 香薷在四月生苗，到九月才开花结穗，禀受火土之气而生，在金水之气中成熟。暑气是相火行使令权，往往先侵犯心包经，因为同类相求。心包与胃口紧密相应。暑邪侵犯心包，没有不损伤胃的。到了心包络与胃合病，又没有不上乘于肺的。这是先损伤肺阴，进而影响肺阳。此品属性为金与水，能在阳中之阴处，消除郁邪，帮助清化，具有彻上彻下的功效。肺部得到它，则清化运行，清化运行则心包络与胃都得到治理，而肺也能行使主气的职能了。心肺胃在上焦合而营诸阳，只是香薷的功力在于和解金郁，使阳气得以宣布，中气因此转化。其义理在于肺即合于离中之坎，以行其清化，而包络主血，也因肺阴的运行，使得清升浊降，霍乱水气之所由降入心，导致霍乱。（热伤气是指阳中之阴受伤）清浊相互干扰，气机不升降，造成胸痞腹胀。霍乱起于突然之间。这种病多在夏秋之交，即使在寒冬月有发生，也多由伏暑引起。李时珍认为对水肿有奇效。况且所采集的血证各方，难道不是调和营血的对症良药吗？
[修治] 八九月采收，去根留叶，阴干，不要让火接触。局方煎煮时用酒和水，水中顿冷冻饮料（此处原文可能有误或特指某种冷饮疗法，依字面译：将药汁放入冷水中饮用）。简易法是捣筛成粉末，用酒调服，热服以取汗。这是顺应病势而引导，并非无法度。
Jinghu (North and South), Zhongzhou, and the Two Rivers regions all have its growth. Seedlings emerge in April. The leaves resemble those of *Artemisia capillaris* (Yinchen). The spike-like inflorescences resemble those of *Nepeta cataria* (Jingjie). The flowers resemble those of *Perilla frutescens* (Shuisu). However, the odor is distinctly different.
One variety has large leaves and square stems; another variety has the finest leaves and grows only a few inches high, yet its fragrance is superior. This is *Elsholtzia splendens* (Shi Xiangru). It is best harvested when it blooms and forms spikes in September.
The taste is pungent (Xin), and the qi is slightly warm. Its action can ascend or descend, belonging to Yang. It enters the Foot-Yangming Stomach Meridian, Foot-Taiyin Spleen Meridian, and Hand-Shaoyin Heart Meridian. Its main indications are to disperse pathogenic qi from the Lungs, assist the Lungs in clearing and transforming, and restore clear qi. It treats abdominal pain, vomiting, and diarrhea caused by Huoluan (Cholera-like syndrome), dissipates edema, promotes urination, stops hematemesis (vomiting blood) and epistaxis (nosebleed), and treats internal heat due to heatstroke. It possesses the efficacy of treating conditions from top to bottom and is very effective in treating water swelling. When the Lungs receive it, the functions of clearing and transforming proceed, and heat naturally subsides. (Danxi) It is also effective for distension diseases. (Also) Xiangru Yin (Elsholtzia Decoction) is a primary medicine for treating summerheat.
If one suffers from summerheat due to irregular diet and overexertion damaging the healthy qi, presenting with high fever, intense thirst, profuse sweating like rain, irritability, panting, and shortness of breath, one should use Xiangru to benefit qi, along with formulas such as Renshen Baihu Tang (Ginseng and White Tiger Decoction) to drain fire and benefit the primal essence. (Binhu/Li Shizhen) The efficacy of Xiangru lies in treating water-dampness disorders. For example, a patient had loose stools and scanty urine. Palpation revealed a deep and large pulse; the deep pulse indicates interior condition. After stabilizing the condition slightly, Weiling Wan (Cangzhu Pill) was administered. Within two days, urination increased, swelling subsided, and after several days of regulation, full recovery was achieved. This shows that ancient prescriptions contain profound principles, and this herb has miraculous effects in treatment. (Also) Regarding Xiangru treating summerheat, the world has not thoroughly investigated its mechanism. Generally, the prevalence of summerheat is called "Summerheat Pathogen" (Shu Yin). When Lung Metal is affected by pathogens, it is called "Summerheat injuring the Lung." The Lung governs the free flow of water passages, transporting fluids downward to the Bladder. If essential qi does not circulate and overflow properly, causing obstruction in upward transport, the power of Xiangru lies in regulating essential qi. The Classic states: "When Metal is constrained, release it." Releasing the exterior and promoting urination are examples of this. If the Yuanfu (acupoints/sweat pores) are closed and the Youmen (lower jiao gate/metabolic portal) is sealed, the Lung Metal becomes constrained. Opening the Yuanfu thereby opens the Youmen. Thus, its efficacy also lies in the Yuanfu. The Classic says: "The Zang True Qi is highest in the Lung, governing the circulation of Ying and Wei and Yin-Yang qi." Xiangru regulates Ying within the vessels and肃 (clears/disciplines) Wei outside the vessels. It addresses the stagnation of the True Qi in the high source organ (Lung), thereby treating vomiting, diarrhea, and dissipating edema. If the Five Waters suddenly gather to form swelling, examining Huoluan where summerheat is the root—whether the root is Wind, Cold, Dampness, Deficiency, Excess, or Disharmony of Ying and Wei—then the efficacy of Xiangru extends beyond just treating diseases caused by rebellious summerheat. Observing Yijian's treatment of abnormal colds in four seasons, Hui's treatment of unceasing epistaxis, Waitai's treatment of hematemesis gushing like a spring, and Yonglei's records confirm this. (Zhiyi) Yujin (Curcuma Rhizome) and Xiangru have similar yet distinct efficacies. Xiangru leans towards Wei and Yang, while Yujin leans towards Ying and Yin. It opens the Form Organs, fills the Yuanfu, and spreads through the Youmen. Treating edema with Xiangru as the Sovereign herb, combined with Renshen (Ginseng), Baizhu (Atractylodes), Mugua (Chaenomeles), Fuling (Poria), Chenpi (Tangerine Peel), Baishao (White Peony Root), and Cheqianzi (Plantago Seed), yields good results. For treating summerheat, Xiangru Yin has versions with ten ingredients (remove Renshen and Baizhu if there is cough); some have six ingredients; some add Huanglian (Coptis Rhizome). Take one jin of Xiangru, one dou of water, boil until extremely soft, remove dregs, and further reduce to an extract. A simple method is to grind into powder, mix with wine, take hot to induce sweating. This is guiding according to the trend, not violating methods.
[Discussion] Xiangru sprouts in April and blooms/forms spikes in September. It is born from the Qi of Fire and Earth and matures in the Qi of Metal and Water. Summerheat is the command of Ministerial Fire, often first invading the Pericardium Meridian due to similarity. The Pericardium corresponds closely to the Stomach opening. When summerheat invades the Pericardium, it inevitably damages the Stomach. When the Pericardium Collateral and Stomach suffer combined disease, it inevitably affects the Lung upwards. This first injures Lung Yin, then affects Lung Yang. This product belongs to Metal and Water. It can eliminate constrained pathogens in the Yin within Yang, assist clearing and transforming, and possess the efficacy of treating from top to bottom. When the Lungs receive it, clearing and transforming proceed; once these proceed, both the Pericardium Collateral and Stomach are treated, and the Lung can resume its function of governing Qi. The Heart, Lungs, and Stomach combine in the Upper Jiao to nourish all Yang. However, the efficacy of Xiangru lies in resolving Metal constraint, allowing Yang Qi to be disseminated, and thus transforming Middle Qi. Its principle lies in the Lung combining with Kan within Li to perform its clearing and transforming functions. Since the Pericardium governs Blood, it also benefits from the operation of Lung Yin, leading to the ascent of Clear and descent of Turbid. The origin of Huoluan and Water Qi descending into the Heart leads to Huoluan. (Heat injuring Qi refers to injury of Yin within Yang.) When Clear and Turbid interfere with each other, and Qi fails to ascend and descend, chest stuffiness and abdominal distension occur. Huoluan arises suddenly. This disease mostly occurs at the transition between Summer and Autumn. Even if it occurs in winter months, it is mostly due to latent summerheat. Binhu considers it highly effective for edema. Moreover, regarding the various prescriptions for blood disorders collected, are they not precisely matching medicines for harmonizing Ying?
[Processing] Harvest in August and September. Remove roots, keep leaves, dry in shade. Do not let it touch fire. In Ju Fang, decoct with wine and water; drink the liquid chilled in cold water. For simplicity, grind into powder, mix with wine, take hot to induce sweat. This is facilitating according to the condition, not contrary to medical laws.
