怪症∶欲大便不见粪，而清水倾流，欲小便不见尿，而稀粪前出，此名易肠。乃暑热气

常山作为其引经药。
味甘，微咸，性寒。归入足太阳膀胱经的气分。能通利水道，清除湿热，消除胸痹，治疗目生翳障。清泻肺、肝二经的风热，疏通尿道的涩痛。与牛膝配伍，可疏肝理气并利水；与菟丝子配伍，可补虚明目。若用于补益方剂中，需酒蒸后捣碎研末；若用于泻下或清热方剂中，则炒制后研末。阳气下陷者禁用。
怪异病症：想大便却无粪便排出，只有清水倾泻而出；想小便却无尿液排出，反而先排出稀粪，此病名为“易肠”。这是由于暑热之气横阻于阑门所致。用车前子三两，煎汤服用，一口气顿饮二三碗，大小便自然恢复正常。如果是因为愤怒导致此疾的，用逍遥散加升麻治疗。真阳发动则精窍开启，阴气常致下泄。然而命门之火因心意之邪而动，也是由湿热为患所致。小便通利则湿热外泄，不致使内动真火，使得精窍常闭，而遗精漏泄的危害自然消除，这就是车前子能治疗遗精的原因。如果没有湿热而肾气不固，或者肺气不能下摄，或者心虚不能下交，或者肝胆受惊，相火内炎，导致精液外泄的，妄用车前子利水开窍，反而会使阴气泄于下，阴火动于中，从而导致劳损的形成。使用泽泻、木通、灯心草等利水药物时，切宜斟酌，切勿妄投，以致后悔。车前子的根、叶可用于伏制硫黄、五矾、粉霜。

*Stem Dichroae Radix* (Changshan) serves as its guiding herb.
Sweet, slightly salty, cold. Enters the Qi level of the Foot-Taiyang Bladder Meridian. Promotes urination, dispels damp-heat, removes chest bi-syndrome, and treats corneal opacity. Clears wind-heat from the Lung and Liver; unblocks astringent pain in the urethra. Paired with *Achyranthis Bidentatae Radix* (Niuxi), it soothes the Liver and promotes diuresis. Paired with *Cuscutae Semen* (Tusizi), it tonifies deficiency and brightens the eyes. When included in tonic prescriptions, steam with wine and crush into powder; when included in purgative or clearing prescriptions, stir-fry and crush into powder. Contraindicated in cases of sinking of Yang Qi.
Strange syndrome: The desire to defecate is present but no feces are seen, only clear water flows out; the desire to urinate is present but no urine is seen, while loose stool comes out first. This is named "Yichang" (Intestinal Exchange). It is caused by summer-heat qi obstructing horizontally at the Lanmen (Gate of the Large Intestine). Use 3 liang of *Plantaginis Semen* (Cheqianzi), decoct and take orally, drinking two to three bowls in one gulp, so that bowel and bladder functions will naturally normalize. If this disease is caused by anger, treat with *Xiaoyao San* (Free and Easy Wanderer Powder) plus *Cimicifugae Rhizoma* (Shengma). When True Yang moves, the essence aperture opens, and Yin Qi often causes downward leakage. However, the fire of the Mingmen (Gate of Life) moving due to evil thoughts of the mind is also caused by damp-heat pathology. When urination is smooth, damp-heat is excreted externally, preventing internal movement of True Fire, keeping the essence aperture closed, thus eliminating the harm of spermatorrhea/leakage. This is why *Plantaginis Semen* treats spermatorrhea. If there is no damp-heat but Kidney Qi is insecure, or Lung Qi cannot descend and control, or Heart Deficiency fails to communicate downward, or Liver/Gallbladder is startled causing Ministerial Fire to flare internally, leading to seminal emission, recklessly using *Plantaginis Semen* to promote urination and open apertures will instead cause Yin Qi to leak downward and Yin Fire to move within, resulting in consumptive disease. When using herbs like *Alismatis Rhizoma* (Zexie), *Akebiae Caulis* (Mutong), and *Junci Medulla* (Dengcao) to promote urination, one must exercise caution and avoid reckless administration to prevent regret. The roots and leaves can be used to fix/process Cinnabar (Dan Sha), Sulfur (Liu Huang), and Arsenic Trioxide (Fen Shuang).
Sweet, cold. Enters the Qi level of the Hand-Taiyang Small Intestine Meridian and Hand-Yangming Large Intestine Meridian. Treats hematuria and bloody dysentery, brightens the eyes, unblocks strangury,消 dissipates masses (Zhang), and removes blood stasis.
This is *Verbena officinalis* (Mabiancao).
Can be used to fix/process Cinnabar (Dan Sha) and Sulfur (Liu Huang).
Bitter, slightly cold. Enters the Blood level of the Hand-Yangming Large Intestine Meridian and Foot-Jueyin Liver Meridian. Moves blood and stops bleeding, treats lower body sores. Paired with *Salvia miltiorrhiza* (Shuwei Cao - note: likely referring to a local name or specific Salvia species for abdominal swelling context, strictly translating as Mouse-tail Grass per text literal meaning though botanically distinct in standard TCM, here adhering to text "Shuwei Cao"), treats abdominal swelling. Paired with *Zingiberis Rhizoma Recens* (Shengjiang) and yellow wine, treats mastitis. The root is pungent, astringent, warm. Treats early-stage red and white dysentery; roast, crush into powder, and take with rice drink.
The seedlings and leaves, crushed for juice and taken with wine, treat blood heat and toxic sores.
