【主治】人心昏塞，多忘喜卧，取花阴干百日，捣末，日暮水服方寸匕，乃卧思念所欲
事，即于眠中醒悟也（苏颂）。
（《本经》下品）
【释名】时珍曰∶观其名，知其毒矣。
【集解】《别录》曰∶野狼毒生秦亭山谷及奉高。二月、八月采根，阴干。陈而沉水者良。
弘景曰∶宕昌亦出之。乃言止有数亩地生，蝮蛇食其根，故为难得。亦用太山者。今用
出汉中及建平。云与防葵同根，但置水中沉者是野狼毒，浮者是防葵。俗用亦稀，为疗腹内要
药耳。
恭曰∶今出秦州、成州，秦亭原在二州之界。秦陇地寒，元无蝮蛇。此物与防葵都不同
类，生处又别，太山、汉中亦不闻有，陶说谬矣。
志曰∶野狼毒叶似商陆及大黄，茎叶上有毛，根皮黄，肉白。以实重者为良，轻者为力劣。
秦
亭在陇西，奉高是太山下县。陶云∶沉者是野狼毒，浮者是防葵，此不足为信。假使防葵秋冬
采者坚实，得水皆沉；野狼毒春夏采者轻虚，得水皆浮。且二物全别，不可比类。此与麻黄、
橘皮、半夏、枳实、吴茱萸为六陈也。
颂曰∶今陕西州郡及辽、石州亦有之。状如马志所说。
时珍曰∶野狼毒出秦、晋地。今人往往以草 茹为之，误矣。见

【释名】李时珍说：看它的名字，就知道它有毒性了。
【集解】《名医别录》说：野狼毒生长在秦亭山谷以及奉高县。二月和八月采集根部，阴干。陈久且放入水中下沉的质地优良。
陶弘景说：宕昌也出产这种药。据说只有几亩地生长，蝮蛇吃它的根，所以很难得。也有使用泰山产的。现在使用的是汉中及建平出产的。有人说它与防葵同根，但放入水中下沉的是野狼毒，浮起的是防葵。民间很少使用，它是治疗腹内疾病的重要药物。
甄权说：现在产自秦州、成州，秦亭原位于这两个州的边界。秦陇地区气候寒冷，原本没有蝮蛇。此物与防葵完全不同类，产地也不同，泰山、汉中也没听说过有，陶弘景的说法是错误的。
苏颂说：野狼毒叶子像商陆和大黄，茎叶上有毛，根皮黄色，肉质白色。以坚实沉重的为优良，轻飘的为效力较差。
秦亭在陇西，奉高是泰山下的县。陶弘景说：沉水的是野狼毒，浮水的是防葵，这不足以采信。假如防葵在秋冬采集则坚实，入水皆沉；野狼毒在春夏采集则轻虚，入水皆浮。况且这两种药完全不同，不可类比。它与麻黄、橘皮、半夏、枳实、吴茱萸并称为“六陈”。
苏颂说：现在陕西各州郡以及辽州、石州也有出产。形状如马志所说的那样。
李时珍说：野狼毒产于秦地、晋地。现在的人往往用草茹来冒充，这是错误的。（此处原文可能有缺字或排版问题，结合上下文推测指伪品混淆）
【气味】味辛，性平，有大毒。
甄权说：味苦、辛，有毒。
徐之才说：大豆作为它的引经药，适宜用醋炒制，畏麦句姜，惧怕占斯、密陀僧。
【主治功效】治疗咳嗽气逆上冲，破除积聚的食物停滞，寒热引起的停饮水肿，恶疮、鼠瘘、疽蚀，鬼精蛊毒，杀死飞鸟走兽（《神农本草经》）。消除胁下的积块癖疾（《名医别录》）。
治疗痰饮症瘕，也能杀灭老鼠（甄权）。将野狼毒与野葛混合塞入耳中，可治疗耳聋（《抱朴子》）。
【附方】旧方四个，新方六个。
心腹相连疼痛且发胀：用野狼毒二两、附子半两，捣碎过筛，用蜂蜜制成梧桐子大小的丸药。第一天服用一丸，第二天两丸，第三天三丸，达到疗效即止；然后又从一丸开始，至三丸为止，以病愈为标准。（出自《肘后备急方》）
九种心痛：一是虫心痛，二是蛀心痛，三是风心痛，四是悸心痛，五是食心痛，六是饮心痛，七是冷心痛，八是热心痛，九是气心痛。又治疗连年积冷，流注心胸，以及落马堕车导致的瘀血、中恶等证候：九痛丸：用野狼毒（炙香）、吴茱萸（汤泡）、巴豆（去心，炒取霜）、干姜（炮制）、人参各一两，附子（泡去皮）三两，研成粉末，炼蜜制成梧桐子大小的丸药。每次空腹时用温酒送服一丸。（出自《千金方》）
食积：用野狼毒三两、附子一两、旋复花三两，研成粉末，用蜂蜜制成梧桐子大小的丸药。每次服用三丸，饭前用白开水送服，每日三次。（出自《肘后备急方》）
两胁气结：方剂同腹中冷痛方。
一切虫病：用野狼毒捣成粉末，每次服用一钱，用饴糖一块皂荚子大小、少许砂糖，用水化开，睡前空腹服用，次日早晨即可排出虫子。（出自《集效方》）
[此处原文似乎缺失部分症状描述，直接跳到治疗方法] 用猪油、马油调匀涂抹患处。睡觉时不要用被子蒙住头，恐怕药气损伤面部皮肤。这是维扬潘氏所传的方子。（出自《蔺氏经验方》）
[此处原文似乎缺失部分症状描述] 在瓦器内，用唾液擦化成粉末，同清油浸泡药物，高出水面一寸，三天后，待药物下沉、油变清澈，夜间不见灯火光亮时，蘸油涂在疮上，同时口鼻对着药盏吸气，以求见效。（出自《永类方》）
积年干癣
[Maintaining Indications] Treats mental confusion and obstruction, forgetfulness, and excessive desire to sleep. Take the flowers, shade-dry for one hundred days, grind into powder, and take one cun bi (a square-inch measure) with water at dusk. Then lie down and contemplate matters you wish to resolve; you will awaken from sleep with clarity (recorded by Su Song).
(Recorded in the Lower Grade of *Shennong Bencao Jing*)
[Etymology] Li Shizhen said: Judging by its name, one can know it is toxic.
[Collection and Explanation] *Bielu* states: Yelangdu grows in the valleys of Qinting and Fenggao. The roots are harvested in February and August and shade-dried. Those that are aged and sink in water are of good quality.
Tao Hongjing said: It is also produced in Dangchang. It is said to grow only on a few acres, and pit vipers eat its roots, making it rare. Some use those from Mount Tai. Currently, those from Hanzhong and Jianping are used. It is claimed to share the same root as Fangkui, but Yelangdu sinks in water while Fangkui floats. It is rarely used by the common people, being an important medicine for treating abdominal disorders.
Zhen Quan said: It is now produced in Qinzhou and Chengzhou. Qinting was originally located on the border of these two prefectures. The climate in Qinlong is cold, and there were originally no pit vipers. This herb is completely different in category from Fangkui and has a different growing area. There is no record of it in Taishan or Hanzhong; thus, Tao's statement is erroneous.
Su Song said: It is also found in various prefectures in Shaanxi, as well as Liao Prefecture and Shizhou. Its appearance matches the description by Ma Zhi.
Li Shizhen said: Yelangdu is produced in the regions of Qin and Jin. Nowadays, people often substitute it with Caoru, which is a mistake. [Note: Text implies confusion with another plant].
[Aroma and Flavor] Pungent, neutral, highly toxic.
Zhen Quan said: Bitter, pungent, toxic.
Xu Zhicai said: Soybean acts as its guide drug; it should be stir-fried with vinegar. It is incompatible with Maijujiang and fears Zhansi and Mituoseng.
[Maintaining Indications] Treats coughing and rebellious qi rising upward; breaks up food stagnation and accumulations; treats edema caused by cold and heat; malignant sores, scrofula, ulcerative lesions, ghost essence, gu poison; kills flying birds and running beasts (*Shennong Bencao Jing*). Eliminates hypochondriac masses and癖疾 (*Bielu*).
Treats phlegm-fluid retention and mass formations; also kills rats (Zhen Quan). Mixes Yelangdu with Yege and inserts them into the ear to treat deafness (*Baopuzi*).
[Attached Formulas] Four old formulas, six new formulas.
Heart and abdomen connected pain with distension: Use 2 liang of Yelangdu and 0.5 liang of Fuzi. Pound and sieve, make pills the size of wutong seeds. Take one pill on the first day, two on the second, three on the third, then stop; then restart from one pill up to three pills again, until cured. (*Zhouhou Beiji Fang*)
Nine types of heart pain: 1. Worm, 2. Borer, 3. Wind, 4. Palpitation, 5. Food, 6. Drink, 7. Cold, 8. Heat, 9. Qi. Also treats chronic accumulated cold flowing into the heart and chest, as well as conditions resulting from falling from horses or carts, blood stasis, and evil influences: Jiutong Wan (Nine-Pain Pill): Use Yelangdu (roasted until fragrant), Wuzhuyu (soaked in hot water), Badou (remove heart, stir-fry to extract frost), Ganjiang (processed), Renshen each 1 liang, and Fuzi (soaked, peel removed) 3 liang. Grind into powder, refine honey to make pills the size of wutong seeds. Take one pill with warm wine on an empty stomach. (*Qianjin Fang*)
Food stagnation: Use 3 liang of Yelangdu, 1 liang of Fuzi, 3 liang of Xuanjinhua. Grind into powder, make pills the size of wutong seeds with honey. Take three pills before meals with plain boiled water, three times a day. (*Zhouhou Beiji Fang*)
Qi knot in both hypochondria: Same formula as for cold pain in the abdomen.
All kinds of parasitic worm diseases: Pound Yelangdu into powder. Take 1 qian per dose. Dissolve a piece of maltose the size of a soap pod and a little rock sugar in water. Take on an empty stomach before sleep; worms will be discharged the next morning. (*Jixiao Fang*)
[Text fragment missing symptom description] Apply mixed with pig fat or horse fat to the affected area. Do not cover your head with a blanket while sleeping, lest the medicinal vapor damage the face. This is a formula passed down by the Pan family of Weiyang. (*Linshi Jingyan Fang*)
[Text fragment missing symptom description] In a clay vessel, dissolve with saliva into powder. Soak the medicine in clear oil, one cun high. After three days, when the medicine sinks and the oil clears, dip into the oil at night when no lamp light is visible, apply to the sore, and inhale the fumes from the medicine cup to achieve effect. (*Yonglei Fang*)
Chronic dry tinea
Malignant wind sores: Equal parts Yelangdu and Qinjiao. Grind into powder. Take one cun bi per dose with warm wine, once or twice a day. (*Qianjin Fang*)
