【附录】问荆 藏器曰∶味苦，平，无毒。主结气瘤
洲渚间，苗如木贼，节节相接，一名接续草。
（出自宋代《嘉祐本草》）
【释名】李时珍说：这种草有节，表面粗糙涩手。用来打磨木器骨器，用它搓擦后就会光亮洁净，所以叫它“木贼”，意即木头之贼。
【集解】苏禹锡说：木贼，产于秦州、陇州、华州、成州等郡靠近水边的地方。苗高一尺左右，丛生。每根茎只有一干，没有花和叶，一寸寸都有节，颜色青绿，冬天也不凋谢。四月采集。
苏颂说：各地靠近水边的地方都有生长，采集没有时间限制，现在使用非常多。
李时珍说：丛丛直立向上生长，长的有二、三尺高，形状像荸荠的苗以及粽心草，但中间空心且有节，又有点像麻黄的茎但稍粗一些，没有枝叶。
【茎】
【气味】味甘、微苦，无毒。李时珍说：性温。
【主治】眼疾，退除翳膜，消除积块，补益肝胆，治疗肠风，止痢，以及妇女月经淋漓不断、崩漏下血赤白。（出自《嘉祐本草》）。解肌表之邪，止泪止血，祛除风湿，治疗疝痛，大肠脱肛。
【发明】苏禹锡说：木贼配合牛角䤴（牛角屑）、麝香，可治疗休息痢（久治不愈的痢疾）。配合禹余粮、当归、川芎，可治疗崩漏下血赤白。配合槐蛾、桑耳，可治疗肠风下血。配合槐子、枳实，可治疗痔疮出血。
朱震亨（朱丹溪）说：木贼去掉节后烘干，发汗效果极易显现，本草书中未曾提及这一点。
李时珍说：木贼气温，味微甘苦，中空而轻，属于阳中之阴，药性升浮。与麻黄外形和性质相同，所以也能发汗解肌，升散火郁和风湿，治疗眼目各种血证疾病。
【附方】旧方三个，新方九个。

肠痔下血，多年不止：用木贼、枳壳各二两，干姜一两，大黄二钱半，一起在铫子内炒黑存性，研为细末。每次用粟米饮送服二钱，效果很好。（出自苏颂《图经本草》）
大肠脱肛：将木贼烧至存性，研为细末掺敷患处，按压回去即可停止。另法加龙骨。（出自《三因方》）妇人血崩，气血疼痛难以忍受，无论新旧病程久治不愈者，雷氏木贼散主治：木贼一两，香附子一两，朴硝半两，研为细末。每次服用三钱，血色黑的，用酒一盏煎煮；血色红赤的，用水一盏煎煮，连同药渣一起服用，每日两次。脐下疼痛的，加乳香、没药、当归各一钱，同煎。忌食生冷硬物、猪肉、鱼类、油腻食物及酒类面食。（出自《医垒元戎》）

(Sourced from the Song Dynasty "Jia You Ben Cao")
[Names] Li Shizhen stated: This herb has nodes and a rough, abrasive surface. It is used to polish wood and bone; rubbing it makes the surface smooth and clean, hence the name "Mu Zei" (Wood Thief), implying it acts as a thief against wood.
[Collection & Description] Su Yuxi stated: Mu Zei (Equiseti Herba) grows in areas near water in Qin, Long, Hua, and Cheng prefectures. The shoots are about one chi long and grow in clumps. Each stem has a single axis, without flowers or leaves, with nodes at every inch. The color is green, and it does not wither in winter. It is harvested in April.
Su Song stated: It grows near water in various places and can be harvested at any time; it is currently used extensively.
Li Shizhen stated: It grows upright in dense clusters, reaching two or three chi in height. Its shape resembles the shoots of Eleocharis tuberosa (Biqi) and the grass used for wrapping zongzi, but it is hollow inside with nodes. It also resembles the stems of Ephedrae Herba (Mahuang) but is slightly thicker and lacks branches and leaves.
[Stem]
[Properties & Flavor] Sweet, slightly bitter, non-toxic. Li Shizhen stated: Warm in nature.
[Indications] Treats eye diseases, removes corneal opacities (Yi Yi Mo), dissipates accumulations, benefits the Liver and Gallbladder, treats intestinal wind (Chang Feng), stops dysentery, and addresses continuous menstruation in women and metrorrhagia with red and white discharge (Ben Zhong Chi Bai). It releases the muscle layer, stops tearing and bleeding, dispels wind-dampness, treats hernial pain, and corrects rectal prolapse.
[Elucidation] Su Yuxi stated: When combined with Ox Cornu (Niujiao) and Moschus (Shexiang), Mu Zei treats chronic intermittent dysentery. When combined with Yu Yuliang (Halloysitum Rubrum), Dang Gui, and Xiong Qiong, it treats metrorrhagia with red and white discharge. When combined with Huai E (Hua Er) and Sang Er, it treats blood in stool due to intestinal wind. When combined with Huai Zi and Zhi Shi, it treats hemorrhoidal bleeding.
Zhu Zhenheng stated: Mu Zei, when dried after removing the nodes, induces sweating very easily, a property not mentioned in earlier Materia Medica texts.
Li Shizhen stated: Mu Zei is warm in temperature and slightly sweet and bitter in flavor. It is hollow and light, belonging to Yin within Yang, with ascending and floating properties. It shares similar form and nature with Ephedrae Herba (Mahuang); therefore, it can also induce sweating and release the muscle layer, ascend and disperse fire stagnation and wind-dampness, and treat various blood disorders of the eyes.
[Attached Prescriptions] Three old prescriptions, nine new ones.
Blurred vision with excessive tearing: Mu Zei (nodes removed) and Cyperi Rhizoma (Cangzhu, soaked in rice water) each 1 liang. Grind into powder. Take 2 qian each time, mixed with tea. Honey pills are also acceptable.
Acute throat obstruction: Burn Mu Zei with cow dung until carbonized (preserving efficacy). Take 1 qian with cold water; relief occurs upon slight bleeding. (From "Sheng Hui Fang")
Tongue stiffness with bleeding: Rinse mouth with decoction of Mu Zei; bleeding stops immediately. (From "Sheng Hui Fang")
Incessant bloody dysentery: Mu Zei 5 qian, decoct in water and take warm once daily. (From "Sheng Hui Fang")
Incessant hematochezia: Same prescription as above, taken twice daily. (From "Guang Li Fang")
Intestinal hemorrhoids with bleeding, persistent for years: Use Mu Zei and Aurantii Fructus Pericarpium (Zhike) each 2 liang, Zingiberis Rhizoma Recens (Ganjiang) 1 liang, and Rhei Radix et Rhizoma (Dahuang) 2.5 qian. Stir-fry them together in a pot until blackened but preserving efficacy, then grind into powder. Take 2 qian each time with millet drink. Very effective. (From Su Song's "Tu Jing Ben Cao")
Rectal prolapse: Burn Mu Zei until carbonized, grind into powder, apply to the area, and push back manually to stop prolapse. Alternatively, add Longgu. (From "San Yin Fang")
For women with metrorrhagia, unbearable qi and blood pain, regardless of duration, Lei Shi Mu Zei San is indicated: Mu Zei 1 liang, Cyperi Rhizoma (Xiangfu) 1 liang, Natrii Sulfas (Puxiao) 0.5 liang. Grind into powder. Take 3 qian each time. If the blood is dark, decoct in one zhan of wine; if bright red, decoct in one zhan of water. Take with dregs twice daily. For pain below the navel, add Rushingxiang, Moyao, and Dang Gui each 1 qian, and decoct together. Avoid raw, cold, hard foods, pork, fish, greasy foods, alcohol, and wheat products. (From "Yi Lei Yuan Rong")
Continuous menstruation: Mu Zei (stir-fried) 3 qian, decoct in one zhan of water until reduced to 0.7 zhan. Take warm once daily. (From "Sheng Hui Fang")
Restless fetus: Mu Zei (nodes removed) and Chuanxiong Rhizoma (Chuanxiong) in equal parts. Grind into powder. Take 3 qian each time, decoct with one zhan of water and adding 1 qian of Jin Yin (Silver/Gold flower or foil). (From "Sheng Ji Zong Lu")

[Appendix] Equiseti Arvensis Herba (Wen Jing) Chen Cangqi stated: Bitter, neutral, non-toxic. Treats Qi stagnation and tumors. Grows on islets; shoots resemble Mu Zei with connected nodes. Also known as Jie Xu Cao.
