弘景曰∶入疗癫狂方用，然不可过剂。久服自无嫌，通神健行，足为大益，而仙经不见
用。

时珍曰∶莨菪之功，未见如所说，而其毒有甚焉。煮一、二日而芽方生，其为物可知矣。
莨菪、云实、防葵、赤商陆皆能令人狂惑见鬼，昔人未有发其义者。盖此类皆有毒，能使痰
迷心窍，蔽其神明，以乱其视听故耳。唐安禄山诱奚契丹，饮以莨菪酒，醉而坑之。又嘉靖
四十三年二月，陕西游僧武如香，挟妖术至昌黎县民张柱家，见其妻美。设饭间，呼其全家
同坐，将红散入饭内食之。少顷举家昏迷，任其奸污。复将魇法吹入柱耳中。柱发狂惑，见
举家皆是妖鬼，尽行杀死，凡一十六人，并无血迹。官司执柱囚之。十余日柱吐痰二碗许，
闻其故，乃知所杀者皆其父母兄嫂妻子姊侄也。柱与如香皆论死。世宗肃皇帝命榜示天下。
观此妖药，亦是莨菪之流尔。方其痰迷之时，视人皆鬼矣。解之之法，可不知乎？

【主治功效】剥取人面皮，去除瘢痕（出自《开宝本草》）。外敷治疗白癜风及溃疡（出自《日华子本草》）。捣碎叶片外敷，可立即缓解蝎子蜇伤（李时珍注）。
（读音同“浪荡”。在《神农本草经》中列为下品）
【名称解释】又名天仙子（出自《本草图经》）、横唐（出自《神农本草经》）。
李时珍说：莨菪，又写作“KT KT”（此处原文可能有误，通常指“莨菪”异体或通假，意指其形态或特性）。它的种子服用后，会使人行为狂野、放荡不羁，因此得名。
【集解（考证与描述）】《名医别录》记载：莨菪子生长在海滨河谷及雍州地区。五月采集种子。
陶弘景说：如今到处都有。种子形状很像五味子的核，但非常小。
苏保升说：各地都有。叶子像菘蓝，茎和叶上都有细毛。花是白色的。果实外壳像罂粟状，结出的果实扁而细，像粟米那么大，呈青黄色。六月、七月采集种子，晒干。
苏颂说：到处都有。苗茎高两三尺。叶子像地黄、王不留行、红蓝等植物，但宽度有三指宽。四月开花，紫色。茎荚上有白毛。五月结果，有壳像小石榴状。房中的种子极细，青白色，像粟米粒。
寇宗奭说：凡使用莨菪子，不要用苍耳子，它们的形状相似，只是苍耳子颜色微红，服用无效，现代人常将其混杂在一起。
李时珍说：张仲景在《金匮要略》中提到，蔬菜中有水莨菪，叶子圆而光亮，有毒，误食后会让人狂乱，症状像中风或吐血，可以用甘草汁解毒。
【修治（炮制方法）】寇宗奭说：炮制时，取莨菪子十两，用头醋一镒（古代容量单位），煮至干透为止。然后用黄牛乳汁浸泡一夜，到第二天乳汁变黑，这才是真品。晒干后捣碎过筛使用。
【气味】味苦，性寒，有毒。《名医别录》说：味甘。李权说：味苦、辛，性微热，有大毒。
陈藏器说：性温不寒。
日华子说：性温，有毒。服用后若出现发热，可用绿豆汁、甘草、升麻、犀角共同解毒。
寇宗奭说：有大毒。误服后，毒性冲入心脏，导致极度烦闷，眼前生火。
苏颂说：《神农本草经》说性寒，后人多说是大热。但《史记·淳于意传》记载：淄川王的妃子怀孕后不能哺乳，喝了一撮莨菪药，用酒送服，随即就能哺乳了。如果不能哺乳难道是热药能治疗的吗？另外古方治疗突然发生的癫狂也多用单味莨菪，难道真的是性寒吗？
【主治功效】治疗牙齿疼痛出虫，肌肉麻痹拘急。长期服用可使身体轻盈，使人健步如飞，跑得像奔马一样快，增强意志和体力，通神见鬼。多吃会让人狂跑（出自《神农本草经》）。
治疗癫狂、风痫，肢体颠倒拘挛（出自《名医别录》）。安心定志，使耳目聪明，驱除邪气、驱逐风邪，使白发变黑，主治积聚癖块。
取种子洗净晒干，隔日空腹，用水送服一指捻大小的量。也可以用小便浸泡直到水分吸干，晒干，按上述方法服用。不要让种子破裂，破裂了会让人发狂（陈藏器注）。炒焦研末，治疗下部脱肛，止冷痢。主治蛀牙痛，咬住后虫子会出来（甄权注）。烧烟熏治虫牙，以及清洗阴部汗症（日华子注）。
【发明（理论阐发）】
陶弘景说：进入治疗癫狂的方剂中使用，但不能过量。长期服用自然没有害处，通神健行，足为大益，但仙家经典中不见使用。
甄权说：用锻石清液煮一个时辰，捞出，去掉芽，晒干，用附子、干姜、陈皮、桂心、厚朴制成丸药服用。可去除一切冷气，多年的气痢，非常温暖。不可生服，伤人且让人见鬼，拾针狂乱。
李时珍说：莨菪的功效，没像所说的那样神奇，而其毒性却更严重。煮上一两天芽才长出来，由此可知其物性。莨菪、云实、防葵、赤商陆都能让人狂惑见鬼，以前的人没有揭示其中的道理。大概这类东西都有毒，能使痰迷心窍，遮蔽人的神明，从而扰乱视听。唐代安禄山引诱奚族和契丹人，给他们喝莨菪酒，醉后将其坑杀。还有嘉靖四十三年二月，陕西游僧武如香，挟带妖术到昌黎县百姓张柱家，见其妻貌美。在吃饭时，叫全家同坐，将红色粉末撒入饭中让他们吃。不久全家昏迷，任其奸污。又将厌胜之法吹入张柱耳中。张柱发狂惑，看见全家都是妖鬼，全部杀死，共十六人，都没有血迹。官府逮捕张柱囚禁他。十多天后张柱吐出约两碗痰，听说原因后，才知道被杀的都是他的父母、兄嫂、妻子、侄子。张柱和武如香都被判死刑。世宗肃皇帝命令张贴告示天下。看这种妖药，也是莨菪一类罢了。当其痰迷心窍时，看人都像鬼一样。解救的方法，能不知道吗？

[Indications] Peel human facial skin to remove scars (from *Kaibao Bencao*). Apply externally to treat vitiligo and ulcers (from *Ri Hua Zi Bencao*). Crush leaves and apply externally; it immediately relieves scorpion stings (Note by Li Shizhen).
(Pronounced "lang dang". Listed as Lower Grade in *Shennong Bencao Jing*.)
[Names] Also known as Tian Xian Zi (Heavenly Immortal Bean) (from *Bencao Tujing*), Heng Tang (from *Shennong Bencao Jing*).
Li Shizhen states: Lang Dang is also written as [variant characters]. Its seeds, when ingested, cause people to behave wildly and recklessly, hence the name.
[Collected Explanations] *Mingyi Bielu* records: Lang Dang Zi grows in river valleys by the sea and in Yongzhou. Seeds are harvested in May.
Tao Hongjing states: It is now found everywhere. The seed shape resembles that of Schisandra chinensis fruit but is extremely small.
Su Baosheng states: It is present in all places. Leaves resemble Isatis tinctoria; stems and leaves have fine hairs. Flowers are white. The fruit shell resembles a poppy capsule; the formed fruit is flat and slender, about the size of millet grain, greenish-yellow. Seeds are harvested in June and July and dried in the sun.
Su Song states: It is found everywhere. Stems and leaves grow two or three chi high. Leaves resemble Rehmannia glutinosa, Galege fructus, and Carthamus tinctorius, but are as wide as three fingers. Flowers bloom in April, purple. Stem pods have white hairs. Fruits form in May, with shells resembling small pomegranates. Seeds inside are very fine, greenish-white, like millet grains.
Kou Zongshi states: When using Lang Dang Zi, do not use Xanthii Fructus (Cang Er Zi); their shapes are similar, but Cang Er Zi is slightly reddish and ineffective when taken. Modern people often mix them.
Li Shizhen states: Zhang Zhongjing, in *Jingui Yaolue*, mentions water Lang Dang among vegetables; its leaves are round and smooth, toxic. Accidental ingestion causes madness, symptoms resembling stroke or hematemesis, which can be detoxified with Licorice juice.
[Processing] Kou Zongshi states: For processing, take ten liang of Lang Dang Zi, boil with one yi of first-run vinegar until dry. Then soak in yellow ox milk overnight. If the milk turns black the next day, it is genuine. Dry and grind through a sieve for use.
[Flavor and Property] Bitter, cold, toxic. *Mingyi Bielu* states: Sweet. Li Quan states: Bitter, acrid, slightly hot, highly toxic.
Chen Canger states: Warm, not cold.
Ri Hua Zi states: Warm, toxic. If heat develops after ingestion, detoxify with Mung bean juice, Glycyrrhiza uralensis, Platycodon grandiflorus, and Rhinoceros horn (substituted with Buffalo horn in modern practice).
Kou Zongshi states: Highly toxic. Ingestion causes toxicity to rush to the heart, causing severe restlessness and visual hallucinations of fire.
Su Song states: *Shennong Bencao Jing* says it is cold, but later authors often claim it is highly hot. However, *Records of the Grand Historian · Biography of Chunyu Yi* records: The concubine of the King of Zichuan could not lactate after pregnancy. She drank a pinch of Lang Dang medicine with wine and lactated immediately. If inability to lactate were treated with hot herbs, this would make sense. Furthermore, ancient formulas for sudden mania often use single-ingredient Lang Dang; is it truly cold?
[Indications] Treats toothache with worms, muscle paralysis and spasms. Long-term use makes the body light, enhances walking ability, allows running as fast as a galloping horse, strengthens will and power, connects with spirits, and enables seeing ghosts. Overconsumption causes people to run wildly (from *Shennong Bencao Jing*).
Treats epilepsy and wind-phlegm convulsions, limb inversion and spasms (from *Mingyi Bielu*). Calms the mind and stabilizes spirit, brightens eyes and ears, expels evil and wind, turns white hair black, and treats abdominal masses.
Take seeds, wash and dry. On alternate days, take on an empty stomach with water, amount equivalent to one finger-width pinch. Alternatively, soak in urine until moisture is absorbed, dry, and administer as above. Do not break the seeds; broken seeds cause madness (Note by Chen Canger). Charred and ground into powder, it treats rectal prolapse and stops cold-type dysentery. Treats dental caries pain; biting on it causes worms to emerge (Note by Zhen Quan). Burn and smoke to treat dental caries caused by worms, and wash for genital sweating (Note by Ri Hua Zi).
[Invention (Theoretical Discussion)]
Tao Hongjing states: Used in formulas for treating mania, but dosage must not exceed limits. Long-term use is harmless; connecting with spirits and enhancing mobility are significant benefits, yet it is not used in immortal classics.
Zhen Quan states: Boil in clear liquid from calcined iron oxide for one shichen, remove, remove sprouts, dry. Form pills with Aconitum carmichaelii, Zingiber officinale, Citrus reticulata, Cinnamomum cassia, and Magnolia officinalis. Removes all cold qi and chronic qi-dysentery; very warming. Do not take raw; it harms people, causes hallucinations of ghosts, and leads to madness where one picks up needles.
Li Shizhen states: The efficacy of Lang Dang is not as miraculous as described, but its toxicity is more severe. Sprouts only appear after boiling for one or two days, indicating its nature. Lang Dang, Caesalpinia sepiaria, Petasites japonicus, and Phytolacca acintha can all cause madness and hallucinations of ghosts; predecessors did not explain the principle. Generally, these substances are toxic and cause phlegm to confuse the heart orifices, obscuring the spirit and disturbing vision and hearing. In the Tang Dynasty, An Lushan tricked the Xi and Khitan tribes by giving them Lang Dang wine, then buried them while they were drunk. In the 43rd year of Jiajing (1564), a wandering monk Wu Ruxiang from Shaanxi brought demonic arts to the home of Zhang Zhu in Changli County. Seeing Zhang's wife was beautiful, he invited the whole family to eat, adding red powder to the food. Soon the family fell into a coma, allowing him to assault them. He then blew a curse into Zhang Zhu's ear. Zhang Zhu became mad, seeing his family as demons, and killed all sixteen of them without leaving blood traces. The authorities imprisoned Zhang Zhu. After ten days, Zhang Zhu vomited about two bowls of phlegm. Upon learning the cause, it was known that those killed were his parents, siblings, wife, and nephews. Both Zhang Zhu and Wu Ruxiang were sentenced to death. Emperor Shizong ordered notices posted throughout the empire. This demonic drug is indeed of the Lang Dang variety. When phlegm confuses the heart orifices, everyone appears as a ghost. How can one not know the method of rescue?
[Attached Prescriptions] Two old prescriptions, twenty-one new prescriptions.
Sudden onset of mania: Three sheng of Lang Dang Zi ground to powder, soaked in one sheng of wine for several days, strained, and boiled until pillable. Form pills the size of adzuki beans, three pills per dose, three times daily. One should feel tightness in the mouth and face, sensation of insects crawling in the head, and red spots on the forehead and limbs; these indicate recovery. If not recovered, administer again; effect is divine and excellent. (Chen Yanzhi, *Duanju Fang*)
Wind-bi and jue pain: Three qian of Tian Xian Zi (stir-fried), half liang of Da Cao Wu Tou, half liang of Gan Cao, one liang of Wu Ling Zhi. Grind to powder, bind with paste into pills the size of wu-tze seeds, coat with Lu Qing. Take ten pills per dose; men with Schisandra chinensis wine, women with Genkwa flower decoction. (*Shengji Lu*)
Chronic cough with pus and blood: Five qian of Lang Dang Zi (rinse to remove floating ones, boil until sprouting, stir-fry and grind), one chicken egg size of true butter, seven large dates. Decoct together until butter is fully melted. Eat three dates daily. Another formula: Swallow three tuos of Lang Dang Zi, five or six times daily. Li Cheng, Guanglu Temple official, took it with divine effect. (Meng Shen, *Bixiao Fang*) Chronic cough lasting thirty years: Equal parts Lang Dang Zi, Costus root, and Xun Huang. Grind to powder.
