陶隐居说：应当挖掘取用味甘辛的芦根，那些露出水面或漂浮在水面上的芦根，都不堪使用。《唐本草》注解说：这是草根，能治疗呕吐逆气、不能进食，以及胃中热症，对于伤寒患者尤为适宜。它的花叫做蓬茸（音农）。用水煮汁服用，主治霍乱效果很好，使用有验证。
臣禹锡等人谨按《药性论》记载：芦根，作为药物使用，无毒。能解除大热，开胃，治疗呃逆不止。日华子说：治疗寒热往来、时行疾病、烦闷，孕妇心热，以及患痢疾者的口渴。
《图经本草》说：芦根，旧籍未记载其出产州土，现在到处都有，生长在低湿的池塘沼泽中。它的形状都像竹子，但叶子抱着茎生长，没有枝条。花白色，成穗状像茅草花。根也像竹根但节间稀疏。二月、八月采集，晒干。使用时应当极选取水底味甘辛的芦根，那些露出水面或漂浮在水面上的芦根，都不堪使用。谨按《尔雅》所说：芦根称为葭华。郭璞说：芦苇就是苇，苇是芦长成后的样子，称蒹为（与廉同），蒹类似萑（音桓）而细长，高几尺，江东人呼为（与荻同）者称为（他敢切），称为（五患切）。（某字）似苇而小且中空，江东人呼为乌（音丘）的，或者称之为荻。荻到秋天变坚硬成为萑，它们的花都叫苕（徒雕切），它们的嫩芽笋都叫KT（音绻）。如果这样，所谓的芦苇，通指一种植物。所谓的，现在写作蒹的是这种。所谓的，人们把它当作柴火燃烧的是这种。现在的人很少能区分蒹和芦苇。另外北方人把苇和芦当作两种植物。水边低湿处生长的都叫苇；其中细不及手指粗，人家池圃种植的称为芦。其秆稍大，深碧色的，称为碧芦，也难得。然而那么本草所用的芦，现在北方地区称为苇的，都可以通用。古方多单用。葛洪治疗呕吐呃逆。切根用水煮，一次服下一升。《必效方》用童子小便煮服，不超过三升即愈。其蓬茸，主治突然得的霍乱，气息危急的人。取一把煮成浓汁，一次服下二升即愈。兼治鱼蟹中毒，服用它尤其好。其笋，味道微苦，可以食用。方法如同竹笋，只是极寒罢了。
《唐本草》补充：生长在低湿地。茎、叶像竹子，花像荻花，二月、八月采根，晒干使用。雷公说：凡是使用，必须选用逆水生长的芦。其根逆水生长并且黄泡肥厚的，味甘，采得后去掉节须并上面赤黄色的部分，细锉后使用。《圣惠方》：治疗吃马肉中毒，瘙痒疼痛。芦根五两切，用水八升，煮取二升，分三次服用。《千金方》：治疗干呕呃逆，如果手脚厥冷，芦根三斤浓煮汁，饮用。《肘后方》：吃鲈鱼肝，（某鱼）中毒。锉芦根煮汁一、二升，饮用。《梅师方》：吃狗肉不消化，心下坚硬，或者腹胀口干，忽然发热胡言乱语。煮芦根饮用。《金匮玉函方》：治疗五噎心膈气滞烦闷，吐逆不能进食。芦根五两锉，用水三大盏，煮取二盏，去渣。不分时候温服。
Reed Rhizome (Lugen)
Sweet in taste, cold in nature. Primarily treats xiaoke (wasting-thirsting syndrome), clears pathogenic heat (ke re), and stops polyuria (excessive urination).
Tao Hongjing stated: One should dig up and use the rhizomes that are sweet and pungent; those exposed to air or floating on water are unsuitable for use. The commentary of *Tang Bencao* notes: This is a root herb, effective for treating vomiting and retching with inability to eat, and stomach heat; it is particularly beneficial for patients with shanghan (cold damage disease). Its flower is called peng rong (sound: nong). Decocted in water and taken as juice, it primarily treats huoluan (cholera-like disorder) with good efficacy, which has been verified.
Min Yuxi and others, according to *Yaoxing Lun*, recorded: Reed Rhizome (Lugen), used as medicine, is non-toxic. It can resolve intense heat, open the stomach, and treat persistent hiccups (yue). Ri Huazi stated: It treats alternating chills and fever, seasonal epidemics (shiji), irritability, heart heat in pregnant women, and thirst in patients with dysentery (xili).
*Tujing* states: Reed Rhizome (Lugen) was not previously listed with its place of origin; now it is found everywhere, growing in low, wet marshes. Its appearance resembles bamboo, but leaves embrace the stem without branches. The flowers are white and spike-like, resembling mugwort flowers. The root also resembles bamboo root but with sparse nodes. Harvested in February and August, dried in the sun. When used, one must select the sweet and pungent rhizomes from the bottom of the water; those exposed or floating are unsuitable. According to *Erya*, Reed Rhizome (Lugen) is called jia hua. Guo Pu said: Lu and Wei refer to the same plant; Wei is the mature form of Lu. Jian is referred to as (same as Lian); Jian resembles Huan (sound: huan) being slender and tall, several chi high, called by people in Jiangdong as (same as Di). Those called (sound: ta gan) or (sound: wu huan) resemble Wei but are smaller and hollow; people in Jiangdong call Wu (sound: qiu) or Di. Di becomes hard and turns into Huan in autumn; their flowers are all called Tiao (sound: tu diao); their sprouts are all called KT (sound: quan). Thus, Lu and Wei generally refer to one type of plant. The so-called [character], now written as Jian, is this type. The so-called [character], used by people as firewood, is that type. Nowadays, few people can distinguish between Jian and Lu/Wei. Furthermore, people in the north consider Wei and Lu as two different plants. Those growing in low, wet areas by the water are all called Wei; those thinner than a finger, planted in household ponds, are called Lu. Those with slightly thicker stems and deep green color are called Bi Lu (Green Reed), which is rare. Therefore, the Lu used in Bencao, now called Wei in northern regions, can be used interchangeably. Ancient formulas often used it singly. Ge Hong treated vomiting and hiccups by cutting the root, decocting in water, and taking one Sheng at once. *Bixiao Fang* used urine from an uncircumcised boy to decoct it; taking no more than three Shengs resulted in recovery. Its Peng Rong (flower spikes) primarily treats sudden onset of Huoluan with critical breathing. Take one handful, decoct into thick juice, take two Shengs at once for recovery. It also treats poisoning from fish and crab; taking it is especially good. Its shoots have a slightly bitter taste and are edible. Preparation method is like bamboo shoots, but extremely cold in nature.
*Tang Bencao* supplement: Grows in low wetlands. Stems and leaves resemble bamboo, flowers resemble Di flowers. Harvest roots in February and August, dry in sun for use. Lei Gong said: Whenever using, one must select Lu growing against the current. Roots growing against the current and having yellow, plump, thick nodes are sweet in taste. After harvesting, remove nodes, whiskers, and reddish-yellow parts at the top, then finely slice for use. *Shenghui Fang*: Treats poisoning from eating horse meat, causing itching and pain. Cut 5 Liang of Reed Rhizome (Lugen), add 8 Sheng of water, decoct to obtain 2 Sheng, divide into three doses. *Qianjin Fang*: Treats dry vomiting and hiccups, especially if hands and feet are cold. Decoct 3 Jin of Reed Rhizome (Lugen) into thick juice and drink. *Zhouhou Fang*: Treats poisoning from eating Perca liver or [specific fish] liver. Finely slice Reed Rhizome (Lugen), decoct 1-2 Sheng of juice, and drink. *Meishi Fang*: Treats indigestion of dog meat, hardness below the heart, abdominal distension, dry mouth, sudden fever, and delirium. Decoct Reed Rhizome (Lugen) and drink. *Jingui Yufang*: Treats Wuye (Five Obstructions) with chest and diaphragm qi stagnation, irritability, vomiting, and inability to eat. Finely slice 5 Liang of Reed Rhizome (Lugen), add 3 large bowls of water, decoct to obtain 2 bowls, remove dregs. Take warm at any time.
