（隰草）表散风热专治目翳
木贼（专入肝胆）。味甘微苦。气温无毒。中空轻扬。书云形质有类麻黄。升散亦颇相
似。但
此气不辛热。且入足少阳胆足厥阴肝。能于二经血分驱散风热。使血上通于目。（目为肝窍
。）故为去翳明目要剂。初非麻黄味辛性燥。专开在卫腠理。而使身汗大出也。是以疝痛脱
肛。肠风痔漏。赤痢崩带诸血等症。审其果因风热而成者。得此则痛止肛收。肠固血止。而
无不治之症矣！（必审果属风热。方用。）至其去翳明目。功虽有类谷精。能驾甘菊。但谷精
则去星障。甘菊则止调和血药。于障全不能退。此则能去翳障也。然气血亏损。则用谷精木
贼去障。又当兼以芍药熟地滋补肝肾。使目得血能视。若徒用此二味退障。则即加以当归补
助。亦恶气味辛散。（当归辛散。）非其所宜。
（隰草）祛肝风除脾湿活血通气
苍耳子（专入肝脾）。味苦而甘。气温无毒。凡人风湿内淫。气血阻滞。（肝受风则血阻。
脾
受湿则气滞。）则上而脑顶。下而足膝。内而骨髓。外而皮肤。靡不病症悉形。而致症见疥
癣。通身周痹。四肢拘挛。骨节痈肿。顶巅风痛。疳虫湿 。恶肉死肌。疔肿痔漏。腰重膝
屈。按此苦能燥湿。温能通活。为祛风疗湿之圣药。或作膏。（如采根叶。根名万应膏。）或
作汤浴。自然风除湿祛。血活气行。而病即愈。但此通顶连脑。下达督脉。服此最忌猪肉。
（猪肉动风助湿。）及风邪触犯。则遍身发出赤丹。而致病益增甚耳。去刺。酒拌蒸用。
（木贼）疏散风热，专门治疗目生翳膜。
木贼（专入肝胆经）。味甘、微苦。性温，无毒。中空而质地轻扬。医书说其形态质地类似麻黄，升发散邪的作用也颇为相似。但是此药气味不辛热，且主要进入足少阳胆经和足厥阴肝经，能够在这两经的血分中驱散风热，使血液上通于眼睛。（眼睛是肝的窍道。）因此它是去除翳膜、明目的重要药物。它并非像麻黄那样味辛性燥，专门开通卫分和腠理，从而使人出汗大汗淋漓。所以对于疝气疼痛、脱肛、肠风痔漏、赤痢崩漏等各种出血病症，如果确实是因为风热引起的，使用此药则疼痛停止、肛门收回、肠道固摄、血液止住，没有治不好的病症！（必须仔细审查确实属于风热证，方可使用。）至于它去除翳膜明目的功效，虽然与谷精草类似，能驾驭甘菊花，但谷精草主要用于去除星障，甘菊花主要用于调和血药，对于障膜完全不能消退。而木贼则能去除翳障。然而如果是气血亏损，那么使用谷精草、木贼去障时，又应当兼用芍药、熟地黄滋补肝肾，使眼睛得到血液滋养就能视物。如果仅仅使用这两味药退除障膜，即使加上当归辅助补血，也因为当归气味辛散，不适合这种情况。（当归具有辛散之性。）
（苍耳子）祛除肝风，清除脾湿，活血通气。
苍耳子（专入肝脾经）。味苦而甘。性温，无毒。大凡人体的风湿内侵，导致气血阻滞。（肝受风邪则血液阻滞，脾受湿邪则气机停滞。）那么症状就会向上影响到头顶，向下影响到足膝，向内影响到骨髓，向外影响到皮肤，无处不表现出病症，从而导致出现疥癣、全身周痹、四肢拘挛、骨节痈肿、头顶风痛、疳虫湿气、恶肉死肌、疔肿痔漏、腰部沉重膝盖弯曲等症状。按此分析，苦味能燥湿，温性能通活，这是祛风疗湿的圣药。或者制成膏剂（如采集根叶，根部名为万应膏），或者煎汤洗浴，自然风邪得除、湿气得祛、血液流通、气机运行，疾病即可痊愈。但是此药通达头顶连接脑部，下达督脉，服用此药最忌讳猪肉。（猪肉动风助湿。）以及避免风邪触犯，否则遍身发出赤丹，而使病情更加严重。使用时需去掉刺，用酒拌蒸后使用。
(Mu Zei / Equiseti Herba) Disperses wind-heat and is specifically used to treat corneal opacity (eye nebula).
Mu Zei (Equiseti Herba) [Equisetum hiemale] (specifically enters the Liver and Gallbladder meridians). Its taste is sweet and slightly bitter. Its nature is warm, non-toxic. It is hollow and light in texture, tending to ascend and disperse. Medical texts state that its form and substance are similar to Ephedrae Herba (Mahuang, 麻黄), and its ascending and dispersing properties are quite similar. However, this herb does not have a pungent-hot aroma, and it enters the Foot-Shaoyang Gallbladder Meridian and Foot-Jueyin Liver Meridian. It can dispel wind-heat within the blood aspect of these two meridians, allowing blood to flow upwards to the eyes. (The eyes are the orifice of the Liver.) Therefore, it is an essential agent for removing opacities and improving vision. It is not like Mahuang, which is pungent and drying in nature, specifically opening the Wei (Defensive) level and interstices to induce profuse sweating. Thus, for conditions such as hernia pain, rectal prolapse, intestinal wind with hemorrhoids and fistulas, bloody dysentery, metrorrhagia, and other bleeding disorders, if it is confirmed that they are caused by wind-heat, using this herb will stop pain, retract the anus, solidify the intestines, and stop bleeding, leaving no untreatable cases! (It must be carefully verified that the condition indeed belongs to wind-heat before use.) Regarding its efficacy in removing opacities and improving vision, although it is similar to Jinguang (Valerianae Officinalis Radix et Rhizoma? Note: Context implies Gu Jing Cao / Sparganii Rhizoma or similar, but text says Gu Jing. WHO term for Gu Jing Cao is often associated with Valeriana or Sparganium depending on context, here likely referring to a specific clearing herb. Given "Gu Jing" usually refers to Gu Jing Cao / Sparganii Rhizoma in some contexts or potentially a typo for something else, but strictly translating "Gu Jing": Gu Jing (likely referring to Gu Jing Cao / Sparganii Rhizoma or similar clearing heat/herb)). *Correction based on standard TCM*: "Gu Jing" here likely refers to Gu Jing Cao (Sparganii Rhizoma) or potentially a local name. However, looking at "Gan Ju" (Chrysanthemi Flos), "Gu Jing" is often paired. Let's stick to literal translation where possible or standard equivalent. Actually, "Gu Jing" might refer to *Jing Mi* or similar, but in eye formulas, *Gu Jing Cao* is common. Let's assume *Gu Jing Cao* (Sparganii Rhizoma) or keep as Gu Jing. Wait, "Gu Jing" (谷精) usually refers to *Gu Jing Cao*. Let's use *Gu Jing Cao (Sparganii Rhizoma)*.
...similar to Gu Jing Cao (Sparganii Rhizoma), capable of overcoming Gan Ju (Chrysanthemi Flos). But Gu Jing Cao mainly removes star-shaped opacities, and Gan Ju mainly harmonizes blood-invigorating herbs; neither can fully eliminate obstructions. Mu Zei, however, can remove opacities. Nevertheless, if there is a deficiency of Qi and Blood, when using Gu Jing Cao and Mu Zei to remove obstructions, one should simultaneously use Bai Shao (Paeoniae Radix Alba) and Shu Di Huang (Rehmanniae Radix Praeparata) to tonify the Liver and Kidney, so that the eyes receive blood and can see. If only these two herbs are used to reduce obstructions, even adding Dang Gui (Angelicae Sinensis Radix) to assist supplementation is unsuitable because Dang Gui has a pungent-dispersing nature. (Dang Gui is pungent and dispersing.) This is not appropriate for them.
(Cang Er Zi / Xanthii Fructus) Dispels Liver wind, eliminates Spleen dampness, invigorates blood, and promotes Qi circulation.
Cang Er Zi (Xanthii Fructus) [Xanthium strumarium] (specifically enters the Liver and Spleen meridians). Its taste is bitter and sweet. Its nature is warm, non-toxic. Generally, when wind-dampness invades internally, causing stagnation of Qi and Blood: (When the Liver is affected by wind, blood becomes stagnant; when the Spleen is affected by dampness, Qi becomes stagnant.) Symptoms may manifest upward to the vertex of the head, downward to the feet and knees, inwardly to the bone marrow, and outwardly to the skin, with no part unaffected. This leads to conditions such as scabies and tinea, generalized bi-syndrome throughout the body, spasms and contractures of the four limbs, abscesses and swellings of bone joints, wind-pain at the vertex, pediatric malnutrition due to parasites and dampness, foul flesh and necrotic muscle, carbuncles, hemorrhoids, and fistulas, heaviness of the waist, and flexion of the knees. Analyzing this, bitterness can dry dampness, and warmth can promote circulation and activation. Thus, it is a holy medicine for dispelling wind and treating dampness. It can be made into a plaster (such as harvesting roots and leaves, the root is named Wan Ying Gao / Ten-Thousand-Effect Plaster), or decocted for bathing. Naturally, wind is expelled, dampness is removed, blood circulates, and Qi moves, leading to recovery. However, this herb connects the vertex to the brain and descends to the Du Meridian. Taking this herb strictly prohibits the consumption of pork. (Pork generates wind and aids dampness.) And one must avoid exposure to wind pathogens; otherwise, red urticaria (red dan) will erupt all over the body, exacerbating the illness. Remove the spines, stir-fry with wine, and steam before use.
