茅根
味甘，性寒，无毒。主治劳伤导致的身体虚弱消瘦，能补益中气、益气力，消除瘀血、经血闭阻、寒热往来，通利小便，治疗五种淋证（石淋、血淋、膏淋、砂淋、冷淋），清除肠胃间的客热，止渴，坚固筋骨，治疗妇女崩漏（非经期大量出血）。长期服用对人体有益。其苗主要功效是通利水道。又名兰根、茹根、地菅、地筋、兼杜。产于楚地的山谷和田野。六月采集根部。
陶隐居说：这就是现在的白茅菅（音奸）。《诗经》中说：“露彼菅茅”，它的根像渣芹一样，味道甜美。服用它，断绝谷食的效果很好。世俗方剂很少使用，只用于治疗淋证和崩漏罢了。《唐本草》注解说：菅花，味甘，性温，无毒。主治鼻出血、吐血、灸疮。臣禹锡等人谨按《药性论》记载：白茅，作为臣药，能破血，主治消渴症。根治五淋，煎汁服用。陈藏器说：茅针，味甘，性平，无毒。主治恶疮肿毒，未溃破的，煮后服用。吃一根针对应一个孔洞，两根针对应两个孔洞。生茅针外敷金创（金属利器造成的创伤），止血。煮服，主治鼻出血及突发下血。开白花的，功效也相同。针就是茅笋。又说：屋上的茅草，主治突然吐血。细切三升，用酒浸泡后煮，服用一升。屋顶腐烂的茅草，配合酱汁研磨外敷斑疮、蚕啮疮（一种皮肤疮疡）。又名百足虫。茅屋滴下的雨水，能杀云母毒。日华子说：茅针，性凉。通利小肠，痈毒、软疖没有脓头的，浓煎后和酒服用。花用于刀箭创伤，止血止痛。根主治妇女月经不调。又说：茅根，通利血脉淋沥不尽，这是指白花茅根。又说：屋四角的茅草，性平，无毒。主治鼻出血。
《图经》说：茅根，产于楚地的山谷和田野，现在到处都有。春天生苗，铺在地上像针一样，民间称为茅针，也可以食用，对小儿很有益处。夏天开白花，茸茸的样子，到秋天枯萎。它的根非常洁白，也很甘甜美味，六月采集根部使用，现在人取茅针，外敷金创，塞鼻止血，治疗突发下血及尿血，效果显著。刘禹锡《传信方》：治疗有头的痈肿，必须使脓液从特定部位排出，取一根完整的茅锥，全株煎煮十几沸，服用，立刻溃破。如果取两茎就生出两个孔洞，或者折断一枝为二，也会生出两个孔洞。白茅花，也主治金创，止血。又有菅，也是茅类植物。陆机《草木疏》说：菅类似茅但光滑无毛，根下五寸中有白粉的，柔韧适宜做绳索，沤制后更好。未沤制的叫野菅。《诗经》所说的“白茅菅兮”就是这个。入药与茅相同。那些屋顶苫盖经久耐用的茅草，主治突然吐血。细切三升，用酒浸泡，煮后服用一升，病愈。《肘后备急方》：治疗热证。取白茅根四升切碎，用水一斗五升，煮取五升，根据冷热适宜饮用，每日三次服用。又一方：各种竹木刺卡在肉中出不来。取白茅根烧成末，用脂膏调和涂抹。也能治疗因风邪导致的肿胀。
Mao Gen (Imperatae Rhizoma)
Sweet in taste, cold in nature, non-toxic. Primarily treats emaciation and weakness caused by labor injury; tonifies the middle jiao and benefits qi; eliminates blood stasis and blood obstruction; resolves alternating chills and fever; promotes urination; treats five types of Lin syndrome (dysuria with various characteristics); clears pathogenic heat in the stomach and intestines; relieves thirst; strengthens sinews and bones; treats metrorrhagia (uterine bleeding) in women. Long-term consumption is beneficial to the human body. Its seedlings primarily promote water passage. Also known as Lan Gen (Orchid Root), Ru Gen (Root of Ru), Di Jian (Earth Sedge), Di Jin (Earth Sinew), and Jian Du. Grows in valleys and fields in the Chu region. Roots are harvested in June.
Tao Hongjing states: This is the current Bai Mao Jian (White Imperata Sedge). The *Classic of Poetry* says: "Dew on the sedge and grass," its root resembles Zha Qin (a type of vegetable), sweet and delicious. Consuming it is very effective for grain-abstention practices. It is rarely used in common prescriptions, only for treating Lin syndrome and metrorrhagia. The *Tang Bencao* annotation notes: Hua Jian (Flower of Sedge), sweet in taste, warm in nature, non-toxic. Treats epistaxis (nosebleed), hematemesis (vomiting blood), and moxibustion sores. Ministers Yuxi et al., according to *Yao Xing Lun*, state: Bai Mao (White Imperata), as a minister herb, can break blood stasis and treat Xiao Ke (wasting-thirst syndrome). The root cures the five types of Lin syndrome; decoct and drink the juice. Chen Cangqi states: Mao Zhen (Mao Shoot), sweet in taste, neutral in nature, non-toxic. Treats malignant sores and swelling; for those not yet ulcerated, boil and consume. Ingesting one shoot corresponds to one pore, two shoots to two pores. Apply raw Mao Zhen externally to metal weapon wounds to stop bleeding. Boil and consume to treat epistaxis and sudden lower hemorrhage. Those with white flowers have the same efficacy. The shoot is also called Mao Sun (Mao Bamboo Shoot). He further states: Roof thatch treats sudden hematemesis. Finely chop three sheng, soak in wine, boil, and consume one sheng. Rotten thatch from the roof, mixed with soy sauce paste and applied topically, treats ban chuang (spotted sores) and can nie chuang (insect-bite sores). Also known as Bai Zu Chong (Hundred-foot Worm). Water dripping from a thatched roof kills Yun Mu Du (mica toxicity). Ri Huazi states: Mao Zhen is cooling. Unblocks the Small Intestine; treats yong du (carbuncle toxins) and ruan jie (soft boils) without heads; decoct strongly and take with wine. Flowers treat knife and arrow wounds, stopping bleeding and pain. The root treats irregular menstruation in women. He further states: Mao Gen unblocks blood vessels and dribbling discharge; this refers to the white-flowered Mao Gen. He further states: Thatch from the four corners of the house is neutral in nature and non-toxic. Treats nasal hemorrhage.
The *Tu Jing* states: Mao Gen grows in valleys and fields in the Chu region and is now found everywhere. Seedlings emerge in spring, spreading on the ground like needles; commonly called Mao Zhen, which is edible and very beneficial for children. White, fluffy flowers appear in summer, and the plant withers in autumn. The roots are extremely white and sweet; harvested in June. Currently, people use Mao Zhen externally for metal weapon wounds, pack it into the nose to stop hemorrhage, and treat sudden lower hemorrhage and hematuria with remarkable effect. Liu Yuxi's *Chuan Xin Fang*: To treat suppurating carbuncles with heads, one must ensure drainage through specific points. Take one whole Mao Zhui (Mao cone/shoot), decoct fully for about ten boils, and consume; it will immediately cause suppuration and rupture. If two shoots are taken, two pores form; or if one shoot is broken into two, two pores also form. Bai Mao Hua (White Imperata Flower) also treats metal weapon wounds and stops bleeding. There is also Jian, which is a type of Imperata. Lu Ji's *Cao Mu Shu* states: Jian resembles Mao but is smooth and hairless; within five cun below the root, there is white powder; it is flexible and tough, suitable for making ropes, especially after retting. Unretted ones are called Ye Jian (Wild Jian). What the *Classic of Poetry* calls "Bai Mao Jian Xi" is this plant. Used medicinally, it is equivalent to Mao. Thatch from roofs that has been used for a long time treats sudden hematemesis. Finely chop three sheng, soak in wine, boil, and consume one sheng; it is effective until recovery. *Zhou Hou Bei Ji Fang*: Treats heat syndromes. Take four sheng of Bai Mao Gen, chop them, add one dou five sheng of water, decoct to obtain five sheng, drink at a comfortable temperature, three times a day. Another prescription: For bamboo or wood splinters stuck in the flesh. Burn Bai Mao Gen to ash, mix with animal fat/grease, and apply topically. It also treats swelling caused by wind pathogens.
