《神农本草经》记载其主治惊痫（小儿惊风抽搐）、摇头弄舌（头部摇动、舌头吐弄），以及腹中热气。
【发明】蚤休（重楼）是足厥阴肝经的药物，能治疗惊痫、疟疾、瘰疬（颈部淋巴结结核）和痈肿。详细分析《神农本草经》的主治功效，主要是取其开通郁结、引导热邪外出的作用，从而使惊痫、摇头弄舌等由热邪引起的症状自然消除。阳气虚弱者禁用，用醋磨碎后外敷治疗痈肿和蛇毒有效。
《神农本草经》称其为九臼，又名天臼，又名马目毒公，还有术律草、害母草、独脚莲、羞天花、琼田草、山荷叶、八角盘、唐婆镜、鬼药、爵犀、解毒等名称。
味辛，性温，有毒。
《神农本草经》记载其能杀虫毒、鬼疰精物（指鬼疰这种传染病及精怪之物），辟除恶气和不祥之气，驱逐邪气，解除百毒。
【发明】鬼臼味辛性温，是一种以毒攻毒的猛药，《神农本草经》记载其杀鬼疰虫毒、辟恶逐邪，恐怕有顾名思义、名实相符的意思。它用于治疗邪气引发的痈疽、阴疽（阴性疮疡）和蛇毒。《良方》中的“一字神散”，治疗胎死腹中，用无灰酒送服一钱，立即见效。被射工虫（一种水边毒虫）中人导致寒热发作并生疮，取一把鬼臼叶，用醋捣汁服用一升，每日两次，有效。

【发明】苦味能向下泄降，辛味能向上发散，《神农本草经》治疗咳嗽气逆、喉痹咽痛、呼吸不畅，专门取其消散结聚之气的功效，是治疗喉痹咽痛的要药。痘疹中出现的咽痛，随手取效，因为其力量能解散毒邪郁结。治疗腹中邪气上逆、饮食大热，是指体内有宿血发热而言，也就是《名医别录》所说的治疗心脾间老血的说法。《金匮要略》治疗咳嗽且气逆、喉中有水鸡声（类似蛙鸣的痰鸣音），有用射干麻黄汤。又治疗疟母（疟疾日久形成的胁下痞块），鳖甲煎丸中使用烧过的乌扇（射干），取其降低厥阴经相火的作用。火降则血散肿消，痰结自然解开。《千金方》治疗喉痹有乌扇膏；被射工虫毒致生疮，用乌扇、升麻煎服，并以药渣敷在疮上，有效。治疗便毒（腹股沟淋巴结炎等），将射干同生姜煎服，排便两三次即见效。因为其药性善于下降，服用后必然会导致腹泻，体虚之人禁用。其苗称为鸢尾，根称为鸢头，又名东海鸢头。《千金方》治疗蛊毒的方剂中使用了它。
It is also known as Cao Zi He Che, Jin Xian Chong Lou, and commonly called Qi Ye Yi Zhi Hua (Seven Leaves One Flower).
Bitter in taste, slightly cold in nature, toxic.
*Shen Nong Ben Cao Jing* (Divine Farmer's Materia Medica) states it governs jing xian (pediatric convulsions), head shaking, and tongue protrusion, as well as heat qi in the abdomen.
[Invention] Zao Xiu (Chong Lou/Paris polyphylla) is a herb of the Foot Jueyin Liver Meridian. It can treat jing xian (pediatric convulsions), malaria, luo li (scrofula), and yong zhong (carbuncles and swellings). A detailed analysis of the indications in *Shen Nong Ben Cao Jing* reveals that its primary action is to open stagnation and guide out heat, thereby naturally eliminating the pathogenic heat causing symptoms such as head shaking and tongue protrusion associated with jing xian. It is contraindicated for those with deficient Yang qi. Applied externally with vinegar paste, it is effective for treating yong zhong (carbuncles and swellings) and snake venom.
*Shen Nong Ben Cao Jing* names it Jiu Jiu, also Tian Jiu, or Ma Mu Du Gong. Other names include Shu Lv Cao, Hai Mu Cao, Du Jiao Lian, Xiu Tian Hua, Qiong Tian Cao, Shan He Ye, Ba Jiao Pan, Tang Po Jing, Gui Yao, Jue Xi, and Jie Du.
Pungent in taste, warm in nature, toxic.
*Shen Nong Ben Cao Jing* records its ability to kill insect poisons, gui zhu jing wu (pathogenic spirits and infectious diseases like guizhu), repel evil qi and inauspicious influences, drive out pathogenic factors, and resolve hundred toxins.
[Invention] Gui Jiu (Podophyllum emodi) is pungent and warm, a potent herb that uses toxicity to combat toxicity. The record in *Shen Nong Ben Cao Jing* regarding killing gui zhu insect poisons and repelling evil suggests an intention where the name matches the reality. It is used to treat pathogenic carbuncles, yin ju (cold abscesses), and snake venom. In *Liang Fang*, "Yi Zi Shen San" (One-Character Divine Powder) treats retained dead fetus in the uterus; taken with one qian using wine without sediment, it produces immediate effect. For injuries from She Gong Zhong (water bugs causing erysipelas-like lesions) presenting with chills, fever, and sores, take a handful of Gui Jiu leaves, crush with vinegar to extract juice, and drink one sheng twice daily for effectiveness.
*Shen Nong Ben Cao Jing* names it Wu Shan. Its leaves grow in clusters, spreading horizontally on one side resembling bird wings or fans, hence names such as Wu Sha, Wu Chui, Wu Pu, Feng Yi, Gui Shan, Bian Zhu, and Zhang Xian Zhang.
Bitter and pungent in taste, slightly warm in nature, toxic. Soak in rice wash water, boil until cooked, then stir-fry before use.
*Shen Nong Ben Cao Jing* states it governs ke ni shang qi (cough with rebellious qi), hou bi (sore throat with obstruction), yan tong (throat pain), inability to breathe freely, dissipates stagnant qi, treats abdominal rebellious qi, and excessive heat from food and drink retention.
[Invention] Bitterness can drain downward, while pungency can disperse upward. In treating ke ni shang qi, hou bi, yan tong, and breathing difficulty, *Shen Nong Ben Cao Jing* specifically utilizes its function of dissipating stagnant qi, making it a key herb for hou bi and yan tong. For throat pain during smallpox/variolous eruptions, it yields quick results because its strength can resolve toxic stagnation. Treating abdominal rebellious qi and excessive heat from diet refers to internal heat caused by old blood stasis, which corresponds to the statement in *Bie Lu* (Additional Records) about treating old blood in the heart and spleen. *Jin Gui Yao Lue* (Essential Prescriptions of the Golden Cabinet) treats cough with rebellious qi and a sound like a water chicken in the throat using She Gan Ma Huang Tang (Belamcanda and Ephedra Decoction). It also treats nuo mu (malaria mass/splenomegaly); in Bie Jia Jian Wan (Turtle Shell Decoction), Wu Shan (She Gan) is roasted to utilize its ability to descend the ministerial fire of the Jueyin meridian. When the fire descends, blood disperses, swelling subsides, and phlegm nodules resolve naturally. *Qian Jin* (Thousand Gold Formulas) contains Wu Shan Gao for treating hou bi. For sores caused by She Gong poison, Wu Shan and Sheng Ma are decocted and taken orally, with the dregs applied topically to the sore for effectiveness. To treat bian du (buboes/gonococcal lymphadenitis), decoct She Gan with fresh ginger; taking it leads to two or three bowel movements and rapid improvement. Because its nature is good at descending, it inevitably causes diarrhea upon ingestion, and it is contraindicated for persons with deficiency. Its seedling is named Yuan Wei (Iris tectorum), its root is named Yuan Tou, also known as Dong Hai Yuan Tou. It is used in formulas for gu du (gu poisoning) in *Qian Jin*.
