《本经》主膀胱热，利小便，补中益气。久服耳目聪明，轻身不老。
发明 众病皆起于虚，虚而多热，则小便不利，精气日燔，故《本经》主以清利膀胱热

即鼠耳草，又名佛耳草。
味甘性平，无毒。
【发明】《名医别录》记载：鼠耳草主治寒痹（因寒邪闭阻经络所致的肢体疼痛麻木）、寒热咳嗽。李东垣认为：佛耳草治疗寒性咳嗽及痰饮，能清除肺中的寒邪，极大地提升肺气。《日华子本草》说：大抵寒性咳嗽多是火气郁结于体内，寒邪覆盖于体表所致，所以佛耳草、款冬花是必用的药物。《宣明论方》中的透膈散治疗寒邪郁结在肺络引起的咳嗽，使用佛耳草、款冬花、钟乳石、雄黄研成末，并在炉中烧灼，通过竹筒吸入烟雾咽下，若有痰涎则吐出，屡见疗效。
味咸性平，无毒。《名医别录》说：味苦甘微寒，无毒，需炒制后研磨使用。
《神农本草经》主治青盲（视物不清或失明）、目淫（眼部分泌物过多），皮肤生赤色或白色的翳膜，眼睛红肿疼痛流泪，长期服用能增进视力精力，使身体轻健。
【发明】《相感志》说，园中种植决明子，蛇不敢进入。朱丹溪说：决明子能解蛇毒，本于此理而入药，具有明目的功效。《神农本草经》治疗青盲、目淫、眼红流泪，是取其苦寒清热的作用。用水调敷药末涂抹肿毒，贴敷心口可止鼻衄（鼻出血），贴敷太阳穴治疗头痛；做成枕头治疗头风（慢性头痛）。《名医别录》治疗口唇发青，这是主治肝经蓄热的验证。不宜长期服用，长期服用会让人患风病损伤肝脏，搜刮风邪太过，反而招致风热。《神农本草经》说长期服用能增进视力精力、身体轻健，是指针对目疾且肝热内滞的患者而言。如果是脾虚血弱的人，过度使用会导致虚风内扰，这是必然的结果。

《神农本草经》主治膀胱热，通利小便，补益中气益气。长期服用能使耳目聪明，身体轻健不老。
【发明】各种疾病都起因于虚损，虚损而多热，就会导致小便不利，精气日益耗损，所以《神农本草经》主张用其清利膀胱热邪，中气自然恢复，耳目也就聪明了。它能祛热，通利小便，去除阴火，治疗客热丹肿（急性红肿热痛之症）。叶子主治老人在夏秋季节的热淋（小便短赤涩痛），将此叶捣取自然汁服用即可通畅。男子白浊（尿道口流出白色分泌物）用地肤子、白敛制成丸剂，用滚开水送服。妇人白带用地肤子研成末，用热酒送服，屡见疗效。苗叶烧成灰煎取霜状，用于制约砒石粉霜、水银、硫黄、雄黄、硇砂的毒性。
It is *Artemisia arborescens* (Shu Er Cao), also known as Fo Er Cao.
Sweet and neutral in nature, non-toxic.
[Invention] *Ben Cao Jing Ji Zhu* records: Shu Er treats cold bi (painful obstruction syndrome caused by cold pathogen) and cough with alternating chills and fever. Li Dongyuan stated: Fo Er treats cold cough and phlegm, removes cold from the lungs, and greatly raises lung qi. *Ri Hua Zi Ben Cao* states: Generally, cold coughs are mostly due to fire constrained within and cold covering outside; therefore, Fo Er and Duan Dong Hua are essential medicines. The Tou Ge San in *Xuan Ming Lun Fang* treats cough caused by cold constrained in the lung collaterals, using powdered Fo Er, Duan Dong Hua, Stalactite (Zhong Ru), and Realgar (Xiong Huang). These are burned in a furnace, and the smoke is inhaled through a bamboo tube and swallowed. If saliva or phlegm appears, it is spat out, showing frequent efficacy.
Salty and neutral in nature, non-toxic. *Ben Cao Jing Ji Zhu* states: Bitter, sweet, and slightly cold, non-toxic; should be stir-fried and ground before use.
*Shen Nong Ben Cao Jing* treats Qing Mang (blindness or dim vision), excessive ocular discharge, red or white membranes on the skin/eyes, red eyes with pain and tearing. Long-term consumption benefits essence and vision, lightening the body.
[Invention] *Xiang Gan Zhi* says that planting Jue Ming in gardens prevents snakes from entering. Zhu Danxi stated that Jue Ming resolves snake venom, based on this principle for medicinal use, possessing the function of brightening the eyes. *Shen Nong Ben Cao Jing* treats Qing Mang, excessive discharge, red eyes, and tearing, utilizing its bitter-cold property to clear heat. Mixed with water and applied topically to swellings and toxins; applied to the heart region to stop epistaxis (nosebleed); applied to the Taiyang acupoint to treat headache; made into pillows to treat Tou Feng (chronic headache). *Ben Cao Jing Ji Zhu*'s treatment of blue lips verifies its action on liver meridian heat accumulation. It should not be taken long-term; long-term use causes wind diseases damaging the liver. Excessive searching for wind may instead attract wind-heat. When *Shen Nong Ben Cao Jing* states that long-term use benefits essence/vision and lightens the body, it refers specifically to patients with eye diseases and internal stagnation of liver heat. For those with spleen deficiency and blood weakness, overuse will inevitably lead to internal disturbance by deficient wind.
Also known as Luo Shu, or Huang Hao.
Sweet and cold in nature, non-toxic.
*Shen Nong Ben Cao Jing* treats bladder heat, promotes urination, and tonifies middle qi. Long-term consumption makes ears and eyes clear, lightening the body and preventing aging.
[Invention] All diseases arise from deficiency. Deficiency with excess heat leads to difficult urination and daily depletion of essence. Thus, *Shen Nong Ben Cao Jing* advocates clearing bladder heat pathogens; once middle qi recovers, ears and eyes become clear. It can dispel heat, promote urination, remove yin fire, and treat external heat dan zhong (acute red swelling and pain). Leaves treat hot lin (dysuria with scanty dark urine) in the elderly during summer and autumn; crushing fresh leaves to take the natural juice brings immediate relief. For male bai zhuo (white turbid discharge from urethra), combine Difuzi and Bai Lian into pills, taken with boiling water. For female dai xia (leukorrhea), powder Difuzi and take with hot wine, showing frequent efficacy. Seedlings and leaves burned to ash and processed into frost are used to detoxify arsenic trioxide powder, mercury, sulfur, realgar, and nasha (ammonium chloride).
