【校正】并入《图经》中的赤孙施。
【释名】酸浆（《图经》）、三叶酸（《纲目》）、三角酸（《纲目》）、酸母（《纲目》）、醋母（苏恭）、酸箕（李当之）、鸠酸（苏恭）、雀儿酸（《纲目》）、雀林草（《纲目》）、小酸茅。
李时珍说：这种小草就是三叶酸，它的味道像醋。它与灯笼草的酸浆，名称相同但实物不同。唐代慎微的《本草》将这种草的方剂收入到灯笼草酸浆之下，是错误的。福建人郑樵在《通志》中说：福州人叫它孙施。那么苏颂的《图经》记载：赤孙施生长在福州，叶子像浮萍的，就是这种草。孙施也是酸箕的讹误罢了。现在将它们合并为一类。
【集解】苏恭说：酢浆草生长在道路旁边阴凉潮湿的地方，丛生。茎头有三片叶子，叶子像细小的浮萍。四月、五月采集，阴干。
寇宗奭说：叶子像水萍，两片小叶和一片大叶同在一枝上，开黄花结黑籽。
苏颂说：南方低湿地及人家园圃中多有生长，北方地区也有生长的。刚生出嫩芽时，小孩子喜欢食用。南方人用它来擦拭石器，使石器变得白如银。
李时珍说：苗高一二寸，丛生铺在地上，极易繁衍。一枝三叶，一叶两片，到了晚上自然合拢贴伏。
矾、砒石。
【气味】味酸，性寒，无毒。
【主治】杀死各种小虫。恶疮，捣碎敷用。食用它，能解除热渴（《唐本草》）。主治小便各种淋证，赤白带下。配合地钱、地龙，治疗沙石淋。煎汤清洗痔疮疼痛脱肛非常有效。捣碎涂抹治疗烫伤火烧蛇蝎咬伤（李时珍）。赤孙施：治疗妇人血结，用一把洗净，细细研磨，用温酒送服（苏颂）。
【附方】旧方两个，新方六个。
小便血淋：酸草捣汁，煎煮五苓散服用。俗名叫醋啾啾。（王璆《百一选方》）。

(From *Tang Bencao*)
[Correction] Merged into *Chishunshi* (Red Sunshi) from *Tu Jing*.
[Names] Suanjiang (*Tu Jing*), Sanyesuan (*Bencao Gangmu*), Sanjiaosuan (*Bencao Gangmu*), Suamu (*Bencao Gangmu*), Cumu (Su Gong), Suanji (Li Dangzhi), Jiusuan (Su Gong), Qier Suan (*Bencao Gangmu*), Qielin Cao (*Bencao Gangmu*), Xiao Suanmao.
Li Shizhen said: This small herb is the Sanyesuan; its taste is like vinegar. It differs in substance from the Suanjiang of Denglong Cao (Physalis alkekengi). Tang Shenwei's *Bencao* incorrectly included formulas for this herb under that of Denglong Cao's Suanjiang. Zheng Qiao of Fujian, in his *Tongzhi*, stated that people in Fuzhou call it "Sunshi". Therefore, Su Song's *Tu Jing* records that Chishunshi grows in Fuzhou with leaves resembling floating duckweed, which is exactly this herb. "Sunshi" is also a corruption of "Suanji". Now they are combined into one entry.
[Collection and Explanation] Su Gong said: Cujiang grows in clusters along roadsides in shady and damp places. The stem tip has three leaves, resembling fine duckweed. Harvested in April and May, dried in the shade.
Kou Zongshi said: The leaves resemble water duckweed; two smaller leaves and one larger leaf share the same branch, producing yellow flowers and black seeds.
Su Song said: It is abundant in low-lying wetlands and household gardens in the South, and occasionally found in the North. When young and tender, children like to eat it. Southerners use it to polish stone vessels, making them white as silver.
Li Shizhen said: The seedlings are one or two cun high, growing in clusters spreading over the ground, reproducing easily. One branch bears three leaves; each leaf consists of two lobes that fold together at dusk.
Fan (Alum), Pishi (Realgar/Orpiment mixture).
[Flavor and Properties] Sour, cold, non-toxic.
[Indications] Kills various small insects. For malignant sores, crush and apply externally. Ingestion relieves heat and thirst (*Tang Bencao*). Treats various types of strangury (dysuria) and leukorrhea (red and white discharge). Combined with Diqian (Marchantia polymorpha) and Dilong (Pheretima), treats lithiasis strangury (sand/stone dysuria). Decoction for washing is highly effective for hemorrhoid pain and rectal prolapse. Crushed and applied topically for burns, scalds, and snake/scorpion bites (Li Shizhen). Chishunshi: Treats blood stagnation in women; take a handful, wash, grind finely, and administer with warm wine (Su Song).
[Attached Formulas] Two old formulas, six new formulas.
Hematuric Strangury: Juice of Suancao crushed, taken with Wu Ling San (Five-Ingredient Powder with Poria) decoction. Commonly known as Cu Jiujiu. (Wang Qiu, *Baiyi Xuanfang*).
Various Stranguries with Red Pain: Wash Sanyesuan Jiangcao, grind to obtain natural juice (1 he), mix with 1 he of wine. Take warm on an empty stomach for immediate relief. (Shen Kuo, *Lingyuan Fang*).
Obstruction of Urine and Stool: A large handful of Suancao, a fistful of Cheqiancao (Plantago asiatica), crushed for juice, mixed with 1 qian of rock sugar, taken as one zhan. Repeat if obstruction persists. (*Zhai Xuan Fang*).
Red and White Leukorrhea: Sanyesuan Cao, dried in shade and powdered. Take 3 qianbi with warm wine on an empty stomach. (*Qianjin Fang*).
Hemorrhoidal Bleeding: A large handful of Qielin Cao, boiled in 2 sheng of water down to 1 sheng. Take three times daily until effective. (*Waitai Miyao*).
Pruritic Tinea: Qier Cao (i.e., Suamu Cao), rub on affected area. Cured after several applications. (*Yonglei Fang*).
Snakebite: Suancao, crushed and applied externally. (Cui Shi Fang).
Tooth Swelling and Pain: One bunch of Suanjiang Cao (washed), 49 grains of Chuanjiao (Sichuan pepper, eyes removed), crushed together, wrapped in silk cloth to the thickness of a chopstick, cut into... bean-sized pieces.
[Appendix] Suancao. *Bielu* lists it as "Name Known, Use Unknown": Mainly used for lightening the body and prolonging life. Grows on shady cliffs near famous mountains and sweet springs. Stem has five glossy green leaves, roots are reddish-yellow. Can dissolve jade. Also called Choucao.
Tao Hongjing said: Li Dangzhi claimed it is the current Suanji Cao, which spreads over the ground and is ubiquitous. However, I fear this is incorrect.
San Ye (Three Leaves)
*Bielu* lists it as "Name Known, Use Unknown": Flavor pungent. Mainly treats chills and fever, and snake/beestings. Grows in fields, stems are small and black-and-white, three chi high, roots black. Harvested in March, dried in shade. Also called Sanshi, Dangtian, and Fuyu.
