（《本经》中品）
【释名】胡薄荷（《天宝方》）、地钱草（《唐本》）、连钱草（《药图》）、海苏。
弘景曰∶积雪草方药不用，想此草以寒凉得名耳。
恭曰∶此草叶圆如钱，荆楚人谓为地钱草，徐议《药草图》名连钱草，余见下。
【集解】《别录》曰∶积雪草，生荆州川谷。
恭曰∶此草叶圆大如钱，茎细而劲，蔓生溪涧侧，生处亦稀。
颂曰∶今处处有之，八九月采苗叶，阴干用。段成式《酉阳杂俎》云∶地钱叶圆茎细，
有蔓延地，一曰积雪草，一曰连钱草。谨按∶《天宝单行方》云∶连钱草生咸阳下湿地，亦
生临淄郡、济阳郡池泽中，甚香。俗间或云圆叶似薄荷，江东吴越丹阳郡极多，彼人常充生
菜食之。河北柳城郡尽呼为海苏，好近水生，经冬不死，咸阳、洛阳亦有之。或名胡薄荷，
所在皆有。单服疗女子小腹疼。
宗 曰∶积雪草南方多有，生阴湿地，不必荆楚。形如水荇而小，面亦光洁，微尖为异。
叶叶各生。今人谓之连钱草，盖取象也。
时珍曰∶按苏恭注薄荷云∶一种蔓生，功用相似。苏颂《图经》云∶胡薄荷与薄荷相类，
但味少甘，生江浙间，彼人多以作茶饮，俗呼为新罗薄荷，《天宝方》所用连钱草是也。据
二说，则积雪草即胡薄荷，乃薄荷之蔓生者尔。又《 仙庚辛玉册》云∶地钱，阴草也。生
荆、楚、江、淮、闽、浙间，多在宫院寺庙砖砌间，叶圆似钱，引蔓铺地，香如细辛，不见
开花也。

【气味】苦，寒，无毒。大明曰∶苦，辛。颂曰∶甘，平，无毒。
时珍曰∶取汁结草砂，伏硫黄。
【主治】大热，恶疮痈疽，浸淫赤 ，皮肤赤，身热（《本经》）。捣敷热肿丹毒（苏恭）。

【附方】旧二，新二
热毒痈肿∶秋后收连钱草。阴干为末。水调敷之。生捣亦可。（寇氏《衍义》）
女子少腹痛∶颂曰∶《天宝单行方》云∶女子忽得小腹中痛，月经初来，便觉腰中切痛
连脊间，如刀锥所刺，不可忍者。众医不别，谓是鬼疰，妄服诸药，终无所益，其疾转增。
审察前状相当，即用此药。其药夏五月正放花时，即采曝干，捣筛为散。每服二方寸匕，和
好醋二小合，搅匀，平旦空腹顿服之。每旦一服，以知为度。如女子阴冷者，即取前药五两，
加桃仁二百枚（去皮尖），熬捣为散，以蜜为丸如梧子大。每旦空腹米饮及酒下三十丸，日
再服，以愈为度。忌麻子、荞麦。（《图经本草》方）。
男女血病∶九仙驱红散∶治呕吐诸血及便血、妇人崩中神效。用积雪草五钱，当归（酒
洗）、栀子仁（酒炒）、蒲黄（炒）、黄连（炒）、条黄芩（酒炒）、生地黄（酒洗）、陈槐花（炒）
各一钱。上部加藕节一钱五分，下部加地榆一钱五分，水二钟，煎一钟服，神效。此方得之
甚秘，此草与本草主治不同，不可晓也。（董炳《集验方》）
牙痛塞耳∶用连钱草（即积雪草），和水沟污泥同捣烂，随左右塞耳内。（《摘玄方》）
【释名】胡薄荷（出自《天宝方》）、地钱草（出自《唐本注》）、连钱草（出自《药图》）、海苏。
陶弘景说：积雪草在方药中不使用，猜想这草是因为性寒凉而得名。
苏恭说：这种草叶子圆得像铜钱，荆楚地区的人叫它地钱草，徐议的《药草图》称它为连钱草，详情见下文。
【集解】《名医别录》说：积雪草，生长在荆州的山谷河流旁。
苏恭说：这种草叶子圆大如铜钱，茎细而坚韧，蔓生在山溪涧边，生长的地方也比较稀少。
苏颂说：现在到处都有，八月九月采集苗叶，阴干后使用。段成式在《酉阳杂俎》中说：地钱叶子圆、茎细，蔓延在地面上，一种叫积雪草，一种叫连钱草。我考证说：《天宝单行方》记载：连钱草生长在咸阳的低湿之地，也生长在临淄郡、济阳郡的池泽中，气味很香。民间有人说它的圆叶像薄荷，江东吴越丹阳郡非常多，那里的人常把它当作生菜食用。河北柳城郡全部叫它海苏，喜欢靠近水生长，经过冬天也不死，咸阳、洛阳也有。有的叫胡薄荷，各地都有。单用可以治疗女子小腹痛。
陈承说：积雪草南方很多地方都有，生长在阴湿的地方，不一定非要在荆楚地区。形状像水荇但较小，表面光洁，微尖是它的特异之处。叶子各不相接。现在人叫它连钱草，大概是取象形之意。
李时珍说：按苏恭注释薄荷时说：有一种蔓生的，功效相似。苏颂《图经》说：胡薄荷与薄荷相类似，只是味道少一点甘甜，生长在江浙一带，那里的人多用来作茶饮，俗称为新罗薄荷，《天宝方》中所用的连钱草就是它。根据这两种说法，那么积雪草就是胡薄荷，是薄荷中蔓生的种类罢了。又《仙庚辛玉册》说：地钱，是阴性的草。生长在荆、楚、江、淮、闽、浙之间，多在宫院寺庙砖砌缝隙间生长，叶子圆像铜钱，牵引藤蔓铺在地上，香气像细辛，不见开花。
【茎叶】
【气味】味苦，性寒，无毒。孟诜说：味苦，辛。苏颂说：味甘，性平，无毒。
【主治】大热，恶疮痈疽，浸淫赤烂，皮肤发红，身体发热（出自《神农本草经》）。捣碎外敷治疗热肿丹毒（苏恭）。主治突发高热，小儿寒热往来，腹内热结，捣汁服用（藏器）。单用治疗瘰疬鼠瘘，寒热症状时发时止（甄权）。用盐调敷贴治肿毒，以及风疹疥癣（《日华子本草》）。胡菝葜：主治风气壅滞攻冲胸膈，煮汤饮用立即见效（士良）。研成汁液，点涂暴发性红眼，效果良好（李时珍）。
【附方】旧方二首，新方二首
热毒痈肿：秋后收集连钱草。阴干研为粉末。用水调匀外敷。新鲜捣碎外敷也可以。（寇氏《衍义》）
女子少腹痛：苏颂说：《天宝单行方》记载：女子忽然感到小腹中疼痛，月经刚来，就觉得腰部剧烈疼痛牵连脊背，像被刀锥刺一样，难以忍受。众医分辨不出，说是鬼疰病，胡乱服用各种药物，最终毫无益处，病情反而加重。仔细审查前面的症状相符，就使用此药。这种药在夏历五月正当开花时，就采摘晒干，捣碎过筛成为散剂。每次服用两方寸匕，和好醋两小合，搅匀，清晨空腹一次性服下。每天早晨服一次，以见效为度。如果是女子阴部寒冷的，就取前药五两，加入桃仁二百枚（去皮尖），炒熟捣碎成为散剂，用蜂蜜制成梧桐子大小的丸药。每天早晨空腹用米饮和酒送下三十丸，每天两次，以痊愈为度。忌食麻子、荞麦。（《图经本草》方）。
男女血病：九仙驱红散：治疗呕吐各种血液及便血、妇人崩中（大量出血）神效。用积雪草五钱，当归（酒洗）、栀子仁（酒炒）、蒲黄（炒）、黄连（炒）、条黄芩（酒炒）、生地黄（酒洗）、陈槐花（炒）各一钱。上部出血加藕节一钱五分，下部出血加地榆一钱五分，水两钟，煎至一钟服用，神效。这个方子得来非常秘密，此草与本草药典主治不同，令人不解。（董炳《集验方》）
(Recorded in the Middle Category of *Shennong Bencao Jing*)
**[Names]** Hu Bohe (Cinnamon Mint, from *Tianbao Fang*), Diqian Cao (Earth Coin Grass, from *Tangben Zhu*), Lianqian Cao (Linked Coin Grass, from *Yaotu*), Haisu.
Tao Hongjing stated: Jixuecao is not used in prescriptions; it is likely named for its cold and cooling nature.
Su Gong stated: The leaves of this herb are round like coins. People in Jingchu call it Diqian Cao. Xu Yi's *Yao Cao Tu* names it Lianqian Cao. Details follow below.
**[Collection and Explanation]** *Mingyi Bielu* states: Jixuecao grows in the valleys and rivers of Jingzhou.
Su Gong stated: The leaves of this herb are round and large like coins, the stems are thin and tough, it grows as a vine by streams, and its growing places are relatively scarce.
Su Song stated: It is now found everywhere. The aerial parts and leaves are harvested in the eighth and ninth lunar months and dried in the shade. Duan Chengshi in *Youyang Zazu* said: Diqian has round leaves and thin stems, spreading over the ground. One variety is called Jixuecao, another Lianqian Cao. I have verified that *Tianbao Danxing Fang* records: Lianqian Cao grows in the low-lying wetlands of Xianyang, and also in the ponds and marshes of Linzi Commandery and Jiyang Commandery, with a very fragrant odor. In common parlance, some say its round leaves resemble Bohe (Peppermint). It is extremely abundant in Jiangdong, specifically Wuyue and Danyang Commanderies, where locals often consume it raw as a vegetable. In Hebei Liucheng Commandery, it is entirely called Haisu. It prefers growing near water, survives through winter, and is also found in Xianyang and Luoyang. Some call it Hu Bohe, which is present in all regions. Used alone, it treats lower abdominal pain in women.
Chen Cheng stated: Jixuecao is abundant in the South, growing in shady and wet areas, not limited to Jingchu. Its shape resembles Shuixing (Water Naiad) but is smaller, with a smooth surface, differing only in having slightly pointed tips. The leaves grow separately. People today call it Lianqian Cao, likely taking its name from its appearance.
Li Shizhen stated: According to Su Gong's annotation on Bohe: "There is a vining variety with similar efficacy." Su Song's *Tujing* states: "Hu Bohe is similar to Bohe, but tastes less sweet. It grows between Jiangsu and Zhejiang, where people often use it as tea. Locally called Xinluo Bohe, this is the Lianqian Cao used in *Tianbao Fang*." Based on these two accounts, Jixuecao is indeed Hu Bohe, which is the vining variety of Bohe. Furthermore, *Xianguang Xin Yu Ce* states: "Diqian is a yin herb. It grows between Jing, Chu, Jiang, Huai, Min, and Zhe, often in the crevices of brick pavements in palaces and temples. The leaves are round like coins, trailing vines spread over the ground, smelling like Xixin (Asarum), and it does not flower."
**[Stems and Leaves]**
**[Flavor and Nature]** Bitter, Cold, Non-toxic. Meng Shen stated: Bitter, Pungent. Su Song stated: Sweet, Neutral, Non-toxic.
Li Shizhen stated: Extracting its juice can coagulate grass sand and fix sulfur (reduce toxicity).
**[Indications]** High fever, malignant sores and carbuncles, oozing red lesions, reddened skin, body heat (*Shennong Bencao Jing*). Crushed and applied externally to treat hot swelling and erysipelas (Su Gong). Treats sudden high fever, alternating chills and fever in children, internal heat accumulation; take the crushed juice orally (Zang Qi). Used alone to treat scrofula and rat chancre, with alternating chills and fever (Zhen Quan). Mixed with salt and applied to swellings and toxic sores, as well as wind-rash and tinea ( *Rihua Bencao*). Huba Qia: Treats qi stagnation attacking the chest and diaphragm; decoct and drink for immediate effect (Shi Liang). Crushed into juice and applied to eyes for acute redness is effective (Li Shizhen).
**[Prescriptions]** Two old prescriptions, two new prescriptions.
**Heat-toxin carbuncle and swelling:** Collect Lianqian Cao after autumn. Dry in the shade and grind into powder. Mix with water and apply externally. Freshly crushed application is also acceptable. (Kou Zongshi, *Yanyi*)
**Lower abdominal pain in women:** Su Song stated: *Tianbao Danxing Fang* records: "Women suddenly suffer from lower abdominal pain. As menstruation begins, severe pain radiates to the waist and spine, feeling like being pierced by knives or awls, unbearable. Physicians fail to distinguish it, attributing it to 'ghost transmission' (chronic infectious disease), and prescribe various medicines indiscriminately, yielding no benefit and worsening the condition. Upon verifying the symptoms match, use this herb. Harvest the herb when it blooms in the fifth lunar month, dry it, crush and sieve it into a powder. Take two fangcun bi (measurements) each time, mixed with two small he (measurements) of good vinegar, stirred evenly, taken in one dose on an empty stomach at dawn. Take once every morning until effective. If the woman suffers from cold in the yin region, take five liang of the aforementioned powder, add two hundred peeled and tip-removed Tao Ren (Peach Kernel), roast and crush into a powder, form pills with honey the size of wu zi (wu berry seeds). Take thirty pills each morning on an empty stomach with rice drink and wine, twice daily, until cured. Avoid hemp seeds and buckwheat." (*Tujing Bencao*)
**Blood disorders in men and women:** Jiuxian Quhong San (Nine Immelants Red-Expelling Powder): Highly effective for vomiting blood, hematochezia, and metrorrhagia in women. Use Jixuecao 5 qian, Dang Gui (wine-washed), Zhizi Ren (wine-fried), Puhuang (fried), Huanglian (fried), Tiao Huangqin (wine-fried), Sheng Dihuang (wine-washed), Chen Huaihua (fried) each 1 qian. For upper bleeding, add Ou Jie (Lotus Node) 1.5 qian; for lower bleeding, add Diyu (Sanguisorba Root) 1.5 qian. Decoct in two zhong of water until one zhong remains, then take. Highly effective. This prescription was obtained secretly. It is puzzling why this herb's indication differs from the standard Materia Medica descriptions. (Dong Bing, *Jiyan Fang*)
**Toothache stuffed in ear:** Use Lianqian Cao (i.e., Jixuecao), mix with mud from drainage ditches, crush thoroughly, and stuff into the affected ear according to the side. (*Zhixuan Fang*)
