（《别录》下品）
【释名】茭草（《说文》）、蒋草。
时珍曰∶按∶许氏《说文》∶菰本作 ，从瓜谐声也。有米谓之凋菰，已见谷部菰米下。
江南人呼菰为茭，以其根交结也。蒋义未详。
【集解】保升曰∶菰根生水中，叶如蔗、荻，久则根盘而浓。夏月生菌堪啖，名菰菜。
三年者，中心生白苔如藕状，似小儿臂而白软，中有黑脉，堪啖者，名菰首也。
藏器曰∶菰首小者，擘之内有黑灰如墨者，名乌郁，人亦食之。晋张翰思吴中 、菰，
即此也。
颂曰∶菰根，江湖陂泽中皆有之。生水中，叶如蒲、苇辈，刈以秣马甚肥。春末生白茅
如笋，即菰菜也，又谓之茭白，生熟皆可啖，甜美。其中心如小儿臂者，名菰手。作菰首者，
非矣。《尔雅》云∶出隧，蘧蔬。注云∶生菰草中，状似土菌，江东人啖之，甜滑。即此也。
故南方人至今谓菌为菰，亦缘此义。其根亦如芦根，冷利更甚。二浙下泽处，菰草最多。其
根相结而生，久则并土浮于水上，彼人谓之菰葑。刈去其叶，便可耕莳，又名葑田。其苗有
茎梗者，谓之菰蒋草。至秋结实，乃雕胡米也。岁饥，人以当粮。
宗 曰∶菰乃蒲类。河朔边人，止以饲马作荐。八月开花如苇。结青子，合粟为粥食，
甚济饥。杜甫所谓“波漂菰米沉云黑”者，是也。

（收录于《名医别录》下品）
【释名】茭草（出自《说文解字》）、蒋草。
李时珍说：查阅许慎的《说文解字》，菰字原本写作“𦸝”，从瓜，谐声。如果长出米来，就叫做“凋菰”，这已经在谷部菰米条下记载过了。
江南地区的人把菰称为茭，是因为它的根茎交错连接。蒋字的含义尚不明确。
【集解】苏保升说：菰的根生长在水中，叶子像甘蔗、荻草一样，时间久了根盘结且粗壮。夏天生长出菌类可以食用，名叫菰菜。
生长三年的菰，中心生出白色的苔状物像藕一样，形状像小儿的手臂，洁白柔软，中间有黑色的脉络，可以食用，名叫菰首。
陈藏器说：小的菰首，掰开里面如果有像墨汁一样的黑灰，名叫乌郁，人们也吃它。晋代张翰思念吴中的莼羹和菰，指的就是这个。
苏颂说：菰根，在江湖池塘沼泽中都有生长。生长在水中，叶子像蒲草、芦苇一类，割下来喂马非常肥壮。春末生出白色的茅笋像竹笋一样，就是菰菜，又叫做茭白，生吃熟吃都可以，味道甜美。其中间部分像小儿手臂的，名叫菰手。说是菰首，就不对了。《尔雅》说：出隧，蘧蔬。注释说：生长在菰草中，形状像土菌，江东人吃它，味道甜滑。就是这个。所以南方人至今把菌类称为菰，也是源于这个意思。它的根也像芦根，寒凉通利的作用更强烈。浙江两地的低洼处，菰草最多。它的根相互纠结而生，时间久了连同泥土一起浮在水面上，当地人称之为菰葑。割去它的叶子，就可以耕种，又叫做葑田。它的苗有茎梗的，叫做菰蒋草。到了秋天结实，就是雕胡米。年成饥荒时，人们把它当作粮食。
寇宗奭说：菰属于蒲类。河北边境的人，只拿它喂马或做垫草。八月开花像芦苇。结青色的种子，和小米一起煮粥吃，很能充饥。杜甫所说的“波漂菰米沉云黑”，指的就是这个。
菰笋
又名茭笋（出自《日用本草》）、茭白（出自《图经本草》）、菰菜（同上）。
【气味】甘味，性冷，质滑，无毒。
孟诜说：性质滑利，不可多吃。
苏颂说：菰的种类都极寒，不可过量食用，对人非常不利，只有服用金石类药物的人适宜吃它。
【主治】通利五脏邪气，治疗饮酒后面部发红，白癜风疮疡，眼睛发红。热毒风气，突然心痛，可以用盐、醋煮食来治疗（孟诜）。去除烦热，止渴，消除眼黄，通利大小便，止住热痢。与鲫鱼混合做成羹汤食用，能开胃，解酒毒，压制丹石类药物引发的毒性发作（陈藏器）。
菰手
又名菰菜（出自《日用本草》）、茭白（出自《通志》）、茭粑（俗名）、蘧蔬（音同“瞿”）。
【气味】甘味，性冷，质滑，无毒。大明说：微毒。
孟诜说：性质滑利，引发冷气，使人下焦寒冷，损伤性功能。禁止与蜂蜜同食，会诱发旧疾。服用巴豆的人不可食用。
【主治】心胸中的浮热风气，滋养牙齿（孟诜）。煮食，可止渴及治疗小儿水泻痢疾（陈藏器）。

(Recorded in the Lower Category of *Bie Lu*)
[Names] Jiaocao (from *Shuowen Jiezi*), Jiangcao.
Li Shizhen says: According to Xu Shen's *Shuowen Jiezi*, the character for Gu originally appeared as "𦸝", with 'Gua' (melon) as the radical and phonetic component. If it produces grain, it is called "Diaogu", which has been recorded under the entry for Gumi in the Grain Section.
People in the Jiangnan region call Gu "Jiao" because its roots are interwoven. The meaning of "Jiang" remains unclear.
[Collection of Explanations] Bao Sheng says: The root of Gu grows in water; its leaves resemble those of sugarcane or reeds. After a long time, the roots become intertwined and thick. In summer, mushrooms grow from it and are edible, named Gucail.
For plants that have grown for three years, a white, moss-like substance grows in the center resembling lotus root. It looks like a child's arm, white and soft, with black veins inside. This is edible and is called Gusou.
Zang Qi says: For small Gusou, when split open, if there is black ash like ink inside, it is called Wuyu, which people also eat. When Zhang Han of the Jin Dynasty missed the Chun geng (duckweed soup) and Gu of Wu Zhong, he was referring to this.
Song says: The root of Gu is found everywhere in rivers, lakes, ponds, and marshes. Growing in water, its leaves resemble cattails or reeds; cut and used to feed horses, they make them very fat. At the end of spring, white reed shoots emerge like bamboo shoots; this is Gucail, also known as Jiaobai. It can be eaten raw or cooked and is sweet and delicious. The part in the center resembling a child's arm is called Goushou. Calling it Gusou is incorrect. *Erya* states: "Chu sui, Qushu." The annotation says: Grows among Gu grass, resembling earth mushrooms; people in Jiangdong eat them, finding them sweet and smooth. This refers to this plant. Hence, southerners still refer to mushrooms as Gu, deriving from this meaning. Its root is similar to Phragmites root but has a stronger cold and purgative effect. In the low-lying areas of Zhejiang, Gu grass is most abundant. Its roots grow intertwined; over time, they float on the water surface along with soil, locally called Gugong. After cutting off the leaves, the land can be cultivated, hence also called Fengtian. The seedlings with stems are called Gujiangcao. By autumn, they bear fruit, which is Diaohu rice. During years of famine, people use it as grain.
Zong says: Gu belongs to the category of Phragmites. People on the northern border only use it to feed horses or as bedding. It flowers in August like reeds. It bears green seeds, which are made into porridge with millet to relieve hunger. This is what Du Fu referred to when he wrote, "The waves drift the Gumi, sinking like dark clouds."
Gusun
Also known as Jiaosun (*Riyong Bencao*), Jiaobai (*Tujing Bencao*), Gucail (same).
[Properties and Flavor] Sweet, cold, slippery, non-toxic.
Shen says: Slippery in nature, should not be consumed in excess.
Song says: All varieties of Gu are extremely cold and should not be overconsumed; they are not beneficial to humans, except for those taking mineral drugs (Dan Shi), for whom it is suitable.
[Indications] Promotes the elimination of pathogenic factors from the five Zang organs; treats facial redness after drinking alcohol, vitiligo sores, and red eyes. For heat toxins and wind pathogens, sudden heart pain, it can be boiled with salt and vinegar for consumption (Meng Shen). Removes irritability and heat, quenches thirst, eliminates yellow eyes, promotes urination and defecation, and stops hot dysentery. Made into a soup with crucian carp, it opens the appetite, resolves alcohol toxicity, and suppresses the toxicity triggered by Dan Shi drugs (Zang Qi).
Goushou
Also known as Gucail (*Riyong Bencao*), Jiaobai (*Tongzhi*), Jiaba (common name), Qushu (pronounced like "Qu").
[Properties and Flavor] Sweet, cold, slippery, non-toxic. Da Ming says: Slightly toxic.
Shen says: Slippery in nature, induces cold qi, causes coldness in the lower jiao, and damages sexual function. Contraindicated with honey, as it triggers chronic diseases. Not to be consumed by those taking Crotonis Fructus (Badou).
[Indications] Treats floating heat and wind pathogens in the chest and heart; nourishes teeth (Meng Shen). Boiled and eaten, it quenches thirst and treats pediatric watery dysentery (Zang Qi).
Gugen
[Properties and Flavor] Sweet, very cold, non-toxic.
Song says: Gugen is similar to Phragmites root but has a stronger cold and purgative effect.
[Indications] Treats deep-seated heat in the intestines and stomach, diabetes mellitus (Xiaoke), and promotes frequent urination. Crushed and the juice drunk ( *Bie Lu*). Burned to ash, mixed with egg white, and applied to treat burns (Zang Qi).
[Attached Formulas] Two old formulas.
Pediatric wind sores: For those that do not heal for a long time. Use the nodes of Gujiangcao, burn them to ash, grind into powder, and apply externally (*Zimu Milu*).
Poisonous snake bites: Burn the roots of Gujiangcao to ash and apply externally (*Guangji Fang*).
Ye (Leaves)
[Indications] Promotes the elimination of pathogenic factors from the five Zang organs (Da Ming).
