蒙汗药大约用天仙子为君，加狐心等物，虽不杀人，然令人迷而不醒。山东村
杏多乘心迷，以取财物，醒来全不记忆，恍惚不能辨别，所以道途误服蒙汗药，以致
头重足轻，口吐涎沫，目瞪不言，此迷心之故也。虽不杀人，久迷不醒亦可畏人。凉
水解之，亦能少苏，但凉水入心，水停心下，倘虚人必变他证。
或曰∶此证必是痰迷心窍，宜生姜开之，投以姜汁乎？殊不知药中天仙子居多，
得姜汁愈迷其心矣。故不可用也。

白茯苓（五钱） 生甘草（二钱） 瓜蒂（七个） 陈皮（五分）
水煎服，即大吐而醒，其从前事断不遗忘，不似凉水之解，如醉如痴也。

凡饮鸩酒，白眼朝天，身发寒战，忽忽不知，大醉之状，心中明白，但不能言，
至目闭即死。夫鸩毒乃鸩鸟之粪，非鸩之羽毛，亦非鹤顶红也。鸩羽与鹤顶红，皆
不杀人，不过生病。惟鸩粪则毒，此鸟出异国，异国人恐言鸟粪，则人必贱之，故
但言鸩，以贵重之也。此鸟非蛇蝎不食，故毒甚于孔雀之粪，孔雀粪冲酒饮，有死有
不死者，而饮鸩则无不死也。盖鸩毒性热功缓，善闭人气，所以不能言，必寒战者，
心中热毒，心脉通目大 ，心热则目上视，目闭而死者心绝，目乃闭也，幸其缓可施救。（鸩音逞）
Menghan Yao (Knockout Drug) generally uses Hyoscyamus niger seed (Tianxianzi, 天仙子的主要成分) as the chief ingredient, added with substances such as fox heart. Although it is not lethal, it causes unconsciousness and inability to wake up. In Shandong, where apricot trees are abundant, some people take advantage of mental confusion to steal property; upon waking, patients have no memory at all, feel disoriented and unable to distinguish reality. Therefore, those who accidentally ingest Menghan Yao on the road suffer from a heavy head and light feet, salivation, staring eyes, and mutism, which is due to the clouding of the Heart spirit. Although not fatal, prolonged unconsciousness is also frightening. Cooling water can detoxify it to some extent, allowing slight recovery, but if cooling water enters the Heart and stagnates below the Heart, in deficient individuals, it will likely transform into other syndromes.
One might ask: This syndrome must be phlegm clouding the orifices of the Heart; should we use fresh ginger to open the orifices by administering ginger juice? Little do they know that Menghan Yao contains a large amount of Tianxianzi; encountering ginger juice will further confuse the Heart spirit. Therefore, it cannot be used.
Zhi Mi Tang (Stop Confusion Decoction)
Poria cocos (Baifuling, 白茯苓) - 5 qian
Raw licorice root (Sheng Gancao, 生甘草) - 2 qian
Melon stalk tip (Gua Di, 瓜蒂) - 7 pieces
Tangerine peel (Chenpi, 陈皮) - 5 fen
Decoct in water and drink. It will induce severe vomiting and awakening; previous events will not be forgotten, unlike detoxification with cooling water which leaves one in a drunken, dazed state.
Another prescription: Drinking cooling water brings relief.
Whenever someone drinks Zhen Jiu (Viper Wine/Poisoned Wine), their white eyes roll upward, the body shivers with cold, consciousness becomes vague and unaware, resembling a state of deep intoxication. The mind remains clear, but speech is impossible. Death occurs when the eyes close. Zhen poison is actually the feces of the Zhen bird, not its feathers, nor is it the red crest of a crane. Zhen feathers and crane crests do not kill people; they only cause illness. Only Zhen feces are toxic. This bird originates from foreign lands; foreigners feared that mentioning bird feces would lead people to despise it, so they simply referred to it as "Zhen" to imply its preciousness. This bird does not eat snakes or scorpions, so its toxicity is greater than that of peacock feces. Peacock feces mixed with wine may cause death in some but not others, whereas drinking Zhen poison ensures death without exception. Generally, Zhen poison is hot in nature and acts slowly, effectively blocking the flow of Qi, hence the inability to speak. The inevitable chills are due to intense heat-toxin in the Heart; the Heart vessels connect to the eyes, so Heart heat causes upward gaze. Eye closure indicates the exhaustion of Heart Qi, leading to death. Fortunately, the slow onset allows for rescue efforts. (Zhen is pronounced 'cheng')
