三棱：味苦，性平，无毒，归肺经和脾经。主要功效为行气、行血，能消除多年形成的症癖（腹内结块），使其由坚硬如石变为水液消散，使用时需将药材用面粉包裹后煨熟，再用醋炒制后入药。
按语：三棱是作用于血分的气药。脾统摄血液，肺主司气机，因此三棱的作用机理与这两脏密切相关。通常血随气上行，若气机郁结则血行不畅而下流停滞，从而形成症癖等疾患，若非三棱不能治愈。但三棱药力峻猛，有斩关夺隘之势，体质虚弱者忌用。
蓬莪术：味苦、辛，性温，无毒，归肺经和脾经。具有开胃消食、破除积聚、行散瘀血、治疗心腹痛、调理月经、主治奔豚气（气从少腹上冲心胸）、平息霍乱吐泻、消除小儿食积等功效。
按语：蓬莀术与三棱形态相似，故其归经也相同，区别仅在于蓬莪术是气中血药，而三棱是血中气药，二者性质均猛烈。蓬莪术只能开破气滞，不能补益正气，虚人禁用。有人称大便因气短而不能接续者也可使用蓬莪术，这是错误的。即使是大小七香丸、集香丸等方剂中使用蓬莪术来理气，难道是用于补气吗？若想使其先入血分，则用醋炒；若想使其先入气分，则用火炮。三棱的处理方法也是如此。
雷公云：凡是使用蓬莪术，应在沙盆中用醋研磨至尽，然后在火旁烘干，再次过筛后使用。
天麻：味辛，性平，无毒，归肝经和膀胱经。治疗成人风热引起的眩晕，小儿惊悸及风痫，祛除各种风邪导致的麻痹不仁，主治瘫痪及言语不利，通利腰膝，增强筋力，活血脉，通利九窍，通畅周身，治疗痈肿。使用时需用湿纸包裹煨熟，无禁忌。其苗名为赤箭，主要功效大致相同。
按语：天麻能祛风，故入厥阴肝经；能祛湿，故入膀胱经。对于真实的风湿病证，其疗效神奇。痈肿之证，多由湿蕴生热所致，天麻也能治疗。赤箭使用其苗，具有由表入里的作用；天麻使用其根，具有由内达外的道理。二者不宜在同一方剂中同用，否则反而导致无效。
雷公云：凡使用天麻时，不要误用衔风草，因为它与天麻相似。只是叶茎不同，衔风草的根、茎、瓣、叶上都有青色斑点。如果使用衔风草的根，切勿将其当作天麻，二者误用会导致肠结（肠道闭塞）的祸患。修治十两天麻时，需用一镒蒺藜子，用慢火熬煎，待熟后，先将十两天麻置于甑中，只用火加热，盖上蒺藜子，内外再用三重纸覆盖密封，并敲击固定，从巳时到未时，取出蒺藜子，再次加热翻炒，将存留的天麻放入瓶中，用炒过的蒺藜子覆盖其中，照前法再盖。又隔一个伏时（约12小时）取出，如此重复七遍。瓶盛取出后，用布擦去表面的水汽汗气，用刀劈开焙干，细切，单独捣碎。如果使用衔风草，修治方法也与天麻相同。
Sanleng (Rhizoma Sparganii): Bitter in taste, neutral in nature, non-toxic. Enters the Lung and Spleen meridians. Its primary functions are to promote Qi circulation and invigorate Blood. It can resolve long-standing Zhengji (abdominal masses) that are hard as stone, transforming them into fluid for elimination. For use, wrap the rhizome in flour and roast it, then stir-fry with vinegar.
Commentary: Sanleng is a Qi-moving herb acting within the Blood aspect. The Spleen controls Blood, while the Lung governs Qi; thus, its mechanism relates to these two organs. Generally, Blood follows Qi upward; if Qi stagnates, Blood flows downward and stagnates, leading to conditions like Zhengji. Such conditions cannot be treated without Sanleng. However, Sanleng has a fierce, breakthrough potency and is contraindicated in patients with deficiency.
Peng'ezhu (Rhizoma Curcumae): Bitter and acrid in taste, warm in nature, non-toxic. Enters the Lung and Spleen meridians. It opens the stomach and aids digestion, breaks up accumulations, moves stagnant Blood, treats heart and abdominal pain, regulates menstruation, manages Ben tun (Qi rushing from the lower abdomen), calms Huoluan (cholera-like vomiting and diarrhea), and resolves pediatric food retention.
Commentary: Peng'ezhu resembles Sanleng, hence their meridian tropisms are similar. The slight difference lies in Peng'ezhu being a Blood-moving herb acting within the Qi aspect, whereas Sanleng is a Qi-moving herb acting within the Blood aspect. Both have fierce properties. Peng'ezhu can open Qi stagnation but cannot tonify Qi; it is forbidden for deficient patients. The claim that it can be used for constipation due to shortness of Qi is erroneous. Even in formulas like Da Xiao Qi Xiang Wan or Ji Xiang Wan where it is used to regulate Qi, is it intended to tonify Qi? To make it enter the Blood first, stir-fry with vinegar; to make it enter the Qi first, roast over fire. Sanleng is processed similarly.
Lei Gong states: When processing, grind the herb with vinegar in a sand basin until fully dissolved, dry it near fire, sieve it finely, and then use.
Tianma (Rhizoma Gastrodiae): Acrid in taste, neutral in nature, non-toxic. Enters the Liver and Bladder meridians. It treats dizziness caused by wind-heat in adults, pediatric fright palpitations and wind epilepsy, dispels numbness and loss of sensation caused by various winds, manages paralysis and speech impediments, benefits the waist and knees, strengthens sinews and muscles, invigorates blood vessels, unblocks the nine orifices, promotes whole-body circulation, and treats carbuncles and swellings. Process by wrapping in wet paper and roasting. There are no specific contraindications. Its aerial part is called Chijian (Ephedra-like sprout), with similar main functions.
Commentary: Tianma dispels wind, thus entering the Jueyin (Liver) meridian; it dispels dampness, thus entering the Bladder meridian. For genuine wind-dampness conditions, its efficacy is miraculous. Carbuncle and swelling conditions often arise from dampness generating heat, which Tianma can also treat. Chijian uses the shoot, possessing a function of moving from the exterior to the interior. Tianma uses the root, possessing a principle of moving from the interior to the exterior. They should not be used together in the same prescription, as this may render them ineffective.
Lei Gong states: Do not use Xianfengcao when processing Tianma, as they resemble each other. The leaves and stems differ; Xianfengcao's roots, stems, petals, and leaves all have green spots. If using the root of Xianfengcao, do not mistake it for Tianma. Confusing the two can lead to intestinal obstruction. To process ten taels of Tianma, use one yi of Tribulus seeds. Simmer slowly. Once cooked, place the ten taels of Tianma in a steamer basket, heat only with fire, cover with Tribulus seeds, seal inside and out with three layers of paper, and secure by beating. Process from Si hour to Wei hour. Remove Tribulus seeds, re-roast and stir-fry them. Place the preserved Tianma in a bottle, cover with the roasted Tribulus seeds, and reseal as before. After another Fu period (approx. 12 hours), remove. Repeat this seven times. After removing from the bottle, wipe off surface moisture with cloth, split with a knife, bake dry, cut finely, and pound separately. If using Xianfengcao, the processing method is identical to that of Tianma.
