（《日华》）
【校正】并入有名未用鼠耳，及东垣《药类法象》佛耳草。
【释名】米曲（《纲目》）、鼠耳（《别录》）、佛耳草（《法象》）、无心草（《别录》）、
香茅（《拾遗》）、黄蒿（《会编》）、茸母。
时珍曰∶曲，言其花黄如曲色，又可和米粉食也。鼠耳言其叶形如鼠耳，又有白毛蒙茸
似之，故北人呼为茸母。佛
耳，则鼠耳之讹也。今淮人呼为毛耳朵，则香茅之茅，似当作毛。按∶段成式《杂俎》云∶
蚍蜉酒草，鼠耳也，一
心草。岂蚍蜉食此，故有是名耶？
【集解】《别录》曰∶鼠耳，一名无心，生田中下地，浓叶肥茎。
藏器曰∶鼠曲草，生平岗熟地，高尺余叶有白毛，黄花。《荆楚岁时记》云∶三月三日，
取鼠曲汁，蜜和为粉，谓之龙舌 ，以压时气。（ ，音板，米饼也
）。山南人呼为香茅。取花杂榉皮染褐，至破犹鲜。江西人呼为鼠耳草也。
汪机曰∶佛耳草，徽人谓之黄蒿。二三月苗长尺许，叶似马齿
苋而细，有微白毛，花黄。土人采茎叶和米粉，捣作粑果食。
时珍曰∶《日华本草》鼠曲，即《别录》鼠耳也。唐宋诸家不知，乃退鼠耳入有名未用
中。李杲《药类法象》用佛耳草，亦不知其即鼠耳也。原野间甚多。二月生苗，茎叶柔软。
叶长寸许，白茸如鼠耳之毛。开小黄花成穗，结细子。楚人呼为米曲，北人呼为茸母。故邵
桂子《瓮天语》云∶北方寒食，采茸母草和粉
【气味】甘，平，无毒。《别录》曰∶鼠耳∶酸，无毒。
杲曰∶佛耳草∶酸，性热。款冬花为之使。宜少食之，过则损目。
【主治】鼠耳∶主痹寒寒热，止咳（《别录》）。鼠曲∶调中益气，止泄除痰，压时气，
去热嗽。杂米粉作糗食，甜美（《日华》）。佛耳∶治寒嗽及痰，除肺中寒，大升肺气（李杲）。
【发明】震亨曰∶治寒痰嗽，宜用佛耳草；热痰嗽，宜用灯笼草。
时珍曰∶《别录》云治寒热止咳，东垣云治寒嗽，言其标也；《日华》云治热嗽，言其
本也。大抵寒嗽，多是火郁于内而寒覆于外也。按陈氏《经验方》云∶三奇散∶治一切咳嗽，
不问久近昼夜无时。用佛耳草五十文，款冬花二百文，熟地黄二两，焙研末。每用二钱，于
炉中烧之，以筒吸烟咽下，有涎吐去。予家一获久病此，医治不效。偶在沅州得一婢，用此
法，两服而愈也。
(From *Rizhen Bencao*)
[Correction] Merged into the "Named but Unused" category, along with *Fouercao* (Earleaf Aster Herb) from Li Dongyuan's *Yaolei Faxiang*.
[Nomenclature] Mi Qu (*Osmunda japonica* Rice Cake), Shu Er (*Pseudognaphalium affine*), Fouercao (*Pseudognaphalium affine*), Wuxin Cao (*Pseudognaphalium affine*), Xiangmao (*Pseudognaphalium affine*), Huanghao (*Artemisia scoparia*), Rongmu.
Li Shizhen stated: The term "Qu" refers to its flowers being yellow like fermented rice cake, and it can be mixed with rice flour for food. "Shu Er" refers to its leaves resembling mouse ears, covered with white fuzz similar to mouse ear hair; hence, northerners call it "Rongmu." "Fou'er" is a corruption of "Shuer." Currently, people in Huai region call it "Maoder," suggesting that the "Mao" in "Xiangmao" should likely be written as "Mao" (hair/fuzz). According to Duan Chengshi's *Za Zu*: "Pifu Jiu Cao is Shuer, also known as Yixin Cao." Could it be named so because ants eat this herb?
[Collection and Explanation] *Bielu* states: Shuer, also called Wuxin, grows in low-lying fields, with dense leaves and thick stems.
Meng Shen stated: Shuqucao grows on hillsides and cultivated land, over a chi high, with white fuzz on leaves and yellow flowers. *Jingchu Suishi Ji* states: On the third day of the third lunar month, collect the juice of Shuqucao, mix with honey to make powder cakes, called Longshe (rice cake), to suppress seasonal pathogens. People in Shannan call it Xiangmao. Flowers are mixed with Zhi bark to dye brown cloth; even when worn out, the color remains bright. People in Jiangxi call it Shuercao.
Wang Ji stated: Fouercao is called Huanghao by people in Hui region. In the second and third months, seedlings grow about a chi long; leaves resemble those of *Portulaca oleracea* but are finer, with slight white fuzz and yellow flowers. Locals harvest stems and leaves, mix with rice flour, pound into cakes for food.
Li Shizhen stated: *Rizhen Bencao*'s Shuqu is the same as *Bielu*'s Shuer. Tang and Song dynasties' experts did not know this, demoting Shuer to the "Named but Unused" category. Li Gao used Fouercao in *Yaolei Faxiang*, also unaware it was Shuer. It is abundant in fields and wilds. Seedlings emerge in February, with soft stems and leaves. Leaves are about one cun long, covered in white fuzz like mouse ear hair. Small yellow flowers bloom in spikes, producing fine seeds. People in Chu region call it Mi Qu, northerners call it Rongmu. Thus, Shao Guizi in *Wengtian Yu* said: Northerners during the Cold Food Festival harvest Rongmu grass and mix with flour...
[Flavor and Properties] Sweet, neutral, non-toxic. *Bielu* states: Shuer is sour, non-toxic.
Gao stated: Fouercao is sour, hot in nature. *Tanzhua* (Coltsfoot Flower) acts as its guiding herb (Shi). It should be consumed sparingly; excessive intake damages the eyes.
[Therapeutic Actions] Shuer: Treats Bi syndrome, aversion to cold and fever, cough (from *Bielu*). Shuqu: Regulates the middle jiao, boosts Qi, stops diarrhea, resolves phlegm, suppresses seasonal pathogens, removes heat-induced cough. Mixed with rice flour to make dry rations, sweet and delicious (from *Rizhen*). Fouer: Treats cold-induced cough and phlegm, clears cold from the lungs, greatly raises Lung Qi (from Li Gao).
[Elucidation] Zhu Zhenheng stated: For cold-phlegm cough, use Fouercao; for heat-phlegm cough, use Denglongcao.
Li Shizhen stated: *Bielu* says it treats cold/fever and cough, and Li Dongyuan says it treats cold cough, referring to the symptoms; *Rizhen* says it treats heat cough, referring to the root cause. Generally, cold coughs often involve fire constrained internally covered by external cold. According to Chen Shi's *Experience Formula*: Sanqi San treats all types of coughs, regardless of duration or time. Use 50 wen worth of Fouercao, 200 wen of Tanzhua, and 2 liang of Shudihuang, bake and grind into powder. Take 2 qian each time, burn in a stove, inhale the smoke through a tube and swallow. Spit out any saliva/phlegm. A family member suffered from chronic cough unresponsive to treatment. Accidentally, a maid in Yuanzhou used this method, cured after two doses.
