【释名】（与“箬”字相同）、
李时珍说：箬竹像竹子但质地柔弱，因此得名。因为它生长在疏朗辽远的地方，所以又被称为“辽”。
【集解】李时珍说：箬生长在南方平坦湿润的沼泽地带。它的根和茎都像小竹子，它的节、笋壳和叶子都像芦苇荻草，但叶子的正面青绿背面淡色，柔软而有韧性，新旧交替，四季常青。南方人采集叶子制作斗笠，以及包裹茶盐、粽子，妇女用来垫在鞋底。
【主治】男女性吐血、鼻出血、呕血、咯血、便血。均将叶子烧存性（保留部分炭化性质），用温开水送服一钱匕。又能通利小便，宣利肺气，治疗喉痹，消除痈肿。（李时珍）
【附方】新增十二首。
一切眼疾：将箬笼烧成灰，淋取汁液清洗眼睛，时间久了自然见效。（《经验方》）
咽喉闭塞疼痛：箬叶、灯心草（烧成灰）等分。吹入患处，非常奇妙。（《集简方》）
耳朵突然疼痛或红肿内部胀满：将经过霜冻的青箬露在外面的、已经腐朽的部分烧存性，研为粉末。敷入耳中，疼痛立即停止。（杨起《简便方》）
肺气壅塞导致鼻衄：箬叶（烧成灰）、白面三钱。研磨均匀，用井花水送服二钱。（《圣济总录》）
箬叶灰、蚕纸灰等分，研为粉末。每次服用二钱，米汤送下。（《圣济总录》）
肠风便血：茶篓内的箬叶，烧存性。每次服用三匙，空腹时用糯米汤送下。或者加入少许麝香。（《百一选方》）
男女血淋，也能治疗五淋：多年煮酒用的酒瓶口的箬叶（三五年至十年的，尤其好）。每次用七个，烧存性，加入少许麝香，陈米饮送下，每日三次服用。有人患此病，服用两次痊愈。福建煮过夏季酒的瓶子多有这种箬叶。（《百一选方》）
小便涩滞不通：干箬叶一两（烧成灰），滑石半两，研为粉末，每次用米汤送服三钱。（《普济方》）
男女转脬（尿潴留）：方法同上。
(From *Bencao Gangmu* [Compendium of Materia Medica])
[Names] (Identical to "Ruo" [Bamboo leaf]),
Li Shizhen stated: Ruo bamboo resembles bamboo but is weaker, hence the name. Because it grows in sparse and distant places, it is also called "Liao".
[Collection and Explanation] Li Shizhen stated: Ruo grows in flat, marshy areas in the southern regions. Its roots and stems resemble small bamboo; its nodes, husks, and leaves resemble reeds and silvergrass, but the upper surface of the leaves is green while the underside is pale. It is soft yet tough, with old and new leaves replacing each other, remaining evergreen throughout the four seasons. People in the south harvest the leaves to make rain hats, wrap tea and salt, package rice dumplings (Zongzi), and women use them as insoles for shoes.
[Flavor and Properties] Sweet, cold, non-toxic.
[Indications] Hematemesis (vomiting blood), epistaxis (nosebleed), hemoptysis (coughing up blood), and hematochezia (blood in stool) in both men and women. The leaves should be charred to retain their properties (burnt to charcoal while keeping internal structure intact) and taken orally with warm water, one Qianbi dose. It can also promote urination, benefit Lung Qi, treat throat obstruction (Hou Bi), and reduce carbuncles and swellings (Li Shizhen).
[Attached Prescriptions] Twelve new prescriptions.
All eye diseases: Char the bamboo hat made of Ruo leaves, leach the ash with water to obtain the juice, and wash the eyes. Effect will be seen after prolonged use. (*Jingyan Fang* [Experience Formula])
Throat obstruction and pain: Equal parts of Ruo leaves and Jiedixin Cao (Herba Centipedae, Centipeda grass) charred to ash. Blow the powder into the affected area; very effective. (*Jijian Fang* [Collected Simple Formulas])
Sudden ear pain or redness and swelling inside the ear: Take the dark green Ruo leaves that have been exposed to frost and are beginning to decay, char them to retain properties, and grind into powder. Apply into the ear canal; pain stops immediately. (Yang Qi, *Jianbian Fang* [Convenient and Simple Formulas])
Lung congestion with epistaxis: Ruo leaves (charred to ash) 3 Qian, white flour 3 Qian. Grind uniformly and take 2 Qian with well water. (*Shengji Zonglu* [General Records of the Holy Emperor's Medical Repository])
Ruo leaf ash and silkworm paper ash in equal parts, ground into powder. Take 2 Qian per dose with rice drink. (*Shengji Zonglu*)
Changfeng Bianxue (Intestinal wind with bloody stool): Ruo leaves from tea baskets, charred to retain properties. Take 3 spoons per dose with glutinous rice soup on an empty stomach. Optionally add a small amount of Muxiang (Moschus, Musk). (*Baiyi Xuanfang* [Selected Formulas from Hundred Considerations])
Xuelin (Bloody strangury) in men and women, also treats Wulin (Five types of strangury): Ruo leaves from the necks of wine bottles used for boiling wine over many years (three to ten years old, especially good). Use seven pieces per dose, char to retain properties, add a small amount of Muxiang (Moschus, Musk), and take with aged rice drink, three times daily. Someone suffering from this was cured after two doses. In Fujian, such leaves are common on bottles used for summer wine brewing. (*Baiyi Xuanfang*)
Astringent and obstructed urination: Dried Ruo leaves 1 Liang (charred to ash), Huashi (Talcum, Talc) 0.5 Liang, ground into powder. Take 3 Qian per dose with rice drink. (*Puji Fang* [Universal Benevolent Prescriptions])
Zhuan Pao (Urinary retention/Cystocele) in men and women: Same method as above.
Chunai (Acute mastitis/Engorgement) and Ru Yong (Breast abscess): Char the Ruo leaves used for wrapping Zongzi on the fifth day of the fifth lunar month, take 2 Qian with wine; the swelling disperses immediately. Repeatedly effective. (*Jiji Xianfang* [Urgent Immortal Formulas])
Dou Chuang Dao Ye (Inverted or collapsed pox lesions): Ruo leaf ash 1 Qian, Muxiang (Moschus, Musk) a small amount. Take with wine. (Zhang Degong, *Douzhen Bianlan Fang* [Practical Formulas for Pox and Rash])
