使用木香的人大多是为了调理气机，但它的味道辛温而浓烈，不免有沉重浑浊的嫌疑，粘牙且味苦，也缺乏宣散透发的力量，因此对于阴中伏阳的病证，如《神农本草经》所说的毒疫温鬼等症，最为适宜。否则，对于一切纯寒无热的气滞等证，配合生姜、橘皮、豆蔻一起使用，也能收到显著疗效。世间有人用香连丸治疗痢疾而导致危害随之而来，这不是木香的过错，而是使用木香的人的过错。
木香不是血分药，但有时血分病也能蒙受它的好处，这在归脾汤中可以见到。归脾汤所治之证是脾气虚寒，不能统摄血液。该方用心、肝、脾三脏的药物，数量不少，但唯独统领全方的只有三味药。远志能唤醒心阳，酸枣仁能收敛肝阴，足以作为引导血液的先导，然而引导至脾时，如果脾的闭拒状态依旧，那么药物也只能徘徊在门外罢了。木香能在脾中行运阳气，阳气一旦发动，便温和舒畅，血液于是回归其经脉，所以木香是开启脾脏功能的钥匙。它能通过温煦气机来荫护血液，作用如此。
按《开宝本草》记载补骨脂的主治，以五劳七伤为首，接着是风虚冷，说明风虚冷是由五劳七伤导致的。紧接着提到骨髓伤败、肾冷精流，这又是由风虚冷导致的。肾脏的风邪，有因热而生的，比如天麻丸中使用萆薢、元参、生地黄。这里则是因虚冷而生风，所以适宜用味辛大温的补骨脂来救治。虚冷生风的症状，正如喻西昌所说，两肾空虚，如同乌风洞一般，阴暗惨淡，漫无止息。
《唐本草》对郁金的记载说是辛苦寒，非常恰当。对姜黄的记载说是辛苦大寒，其实它是温性的而非寒性。正因为误以为它是大寒，所以说它能除风热。邹氏没有仔细考察，也沿袭了这个错误。并且认为姜黄主治心腹结积，是治疗上部的病；郁金主治血淋尿血，是治疗下部的病。本意是想追求精准贴切，却不知道其实并非如此。
姜黄辛苦温，颜色黄，所以入脾治疗腹胀，片子姜黄兼治臂痛，这是脾脏血中的气药。郁金苦寒，外表黄内里赤，性质轻扬，所以入心去除恶血，解除心包络的热邪。它治疗淋血、尿血以及妇女经脉逆行，都是由此产生的疗效，这是心脏的血药。这些都是经过多次试验验证无误的，《唐本草》不必过分固执己见。
Those who use *Muxiang* (Aucklandiae Radix) mostly seek its qi-regulating properties. However, its aroma is pungent, warm, and dense, carrying a suspicion of being heavy and turbid; it sticks to the teeth and tastes bitter, possessing little force for dispersing and venting. Therefore, it is most suitable for conditions where yang is concealed within yin, such as those described in the *Shennong Bencao Jing* (Divine Farmer's Materia Medica) as toxic epidemics or warm ghosts. Otherwise, for all qi-stagnation conditions that are purely cold without heat, combining it with *Shengjiang* (Zingiberis Rhizoma Recens, Fresh Ginger), *Jupi* (Citri Reticulatae Pericarpium, Tangerine Peel), and *Doukou* (Amomi Fructus Rotundus, Round Cardamom) can also yield remarkable effects. In the world, some people use *Xianglian Wan* (Fragrant and Coptis Pill) to treat dysentery, only to have harm follow immediately. This is not the fault of *Muxiang*, but the fault of those who use it improperly.
*Muxiang* is not a blood-invigorating herb, yet sometimes blood disorders benefit from it, as seen in *Guipi Tang* (Restore the Spleen Decoction). The syndrome treated by *Guipi Tang* involves spleen-qi deficiency and cold, failing to control the blood. The formula uses herbs targeting the heart, liver, and spleen, which are numerous, but only three herbs lead the entire prescription. *Yuanzhi* (Polygalae Radix) awakens heart-yang, and *Zaoren* (Ziziphi Spinosae Semen, Jujube Seed) gathers liver-yin, serving adequately as guides for the blood. However, if upon reaching the spleen, the spleen’s closure and rejection remain unchanged, the herbs will merely linger at the door. *Muxiang* can move yang within the spleen; once yang moves, it becomes harmonious and mild, allowing the blood to return to its vessels. Thus, *Muxiang* is the key that unlocks the spleen. It warms the qi to nourish the blood in this manner.
According to the *Kaibao Bencao* (Kaibao Materia Medica), the indications for *Buguzhi* (Psoraleae Fructus, Psoralea Fruit) begin with "five exhaustions and seven injuries," followed by "wind-deficiency-cold." This implies that wind-deficiency-cold results from the five exhaustions and seven injuries. Subsequently, it mentions "marrow injury and degeneration, kidney cold, and seminal leakage," which are caused by wind-deficiency-cold. Wind in the kidney zone can arise from heat, as seen in *Tianma Wan* (Gastrodia Pill) using *Bixie* (Dioscoreae Hypoglaucae Rhizoma, Yam Root), *Yuanshen* (Scrophulariae Radix, Figwort Root), and *Shengdihuang* (Rehmanniae Radix, Rehmannia Root). Here, however, wind arises from deficiency-cold, so it is appropriate to rescue it with the pungent and greatly warm *Buguzhi*. The manifestation of wind arising from deficiency-cold is what Yu Xichang described as "two kidneys empty, like a dark wind cave, bleak and dim, endless and unceasing."
The *Tang Bencao* (Tang Materia Medica) states that *Yujin* (Curcumae Longae Radix, Turmeric Root) is pungent, bitter, and cold, which is very accurate. Regarding *Jianghuang* (Curcumae Longae Rhizoma, Turmeric Rhizome), it states it is pungent, bitter, and greatly cold, but in reality, it is warm, not cold. Because it was mistakenly considered greatly cold, it was said to dispel wind-heat. Zou failed to examine this carefully and perpetuated the error. He also believed that *Jianghuang* treats heart-abdominal accumulations, addressing the upper part, while *Yujin* treats hematuria and bloody urine, addressing the lower part. Intending to be precise and pertinent, he did not realize this was actually incorrect.
*Jianghuang* is pungent, bitter, and warm, with a yellow color, thus entering the spleen to treat abdominal distension. *Pianzi Jianghuang* (Sliced Turmeric Rhizome) additionally treats arm pain; it is an herb that regulates qi within the blood of the spleen. *Yujin* is bitter and cold, yellow on the outside and red inside, with a light and ascending nature, thus entering the heart to remove evil blood and resolve heat in the pericardium meridian. Its efficacy in treating bloody discharge in strangury, hematuria, and retrograde menstruation in women stems from these actions; it is an herb that invigorates blood in the heart. These observations have been verified repeatedly without fail, and one need not rigidly adhere to the *Tang Bencao*.
