〔程〕凡诸毒。多借饮食以投毒。而服毒之人。原自不知。若觉之。则时时煮甘草荠
汤饮之。以二物能解草石百毒也。
外台引肘后云。诸馔食。直尔何容有毒。皆是以毒投之
耳。既不知是何处毒。便应煎甘草荠 汤疗之。汉质帝食饼。魏任城王啖枣。皆致死。即其事也。
证类本草云。金匮玉函。治误饮馔中毒者。未审中何毒。
卒急无药可解。只煎甘草荠 汤服之。入口便活。（案与本经文颇异。故录备考。）
巢源云。凡人往往。因饮食。忽然困闷。少时致甚。乃至死者。名为饮食中毒。言人假以毒物。投食里
而杀人。但其病颊内。或悬壅内。初如酸枣大。渐渐长大。是中毒也。
急治则瘥。久不治。毒入腹则死。但诊其脉。浮之无阳。微细而不可知者。中毒也。
[Cheng Lin's Commentary] All kinds of poisons are mostly administered through food and drink. The person who ingests the poison is originally unaware of it. If they become aware, they should frequently decoct and drink Licorice Root and Shepherd's Purse Decoction (Gancao Jicai Tang), as these two substances can resolve various poisons from herbs, plants, minerals, and metals.
The *Waitai Miyao* cites the *Zhouhou Beiji Fang*: How could various foods naturally contain poison? It is all due to someone deliberately introducing poison into them. Since one does not know the source of the poison, one should decoct Licorice Root and Shepherd's Purse Decoction (Gancao Jicai Tang) for treatment. The death of Emperor Zhi of Han from eating cakes, and the death of the Prince of Rencheng of Wei from eating dates, are examples of such incidents.
The *Zhenglei Bencao* records: The *Jingui Yufang* treats cases of accidental poisoning from food and drink where the specific poison is unknown. In sudden emergencies with no antidote available, one should only decoct and administer Licorice Root and Shepherd's Purse Decoction (Gancao Jicai Tang). Life can be restored upon ingestion. (Note: This differs significantly from the main text, so it is recorded here for reference.)
Chao Yuanfang in the *Zhubing Yuanhou Lun* states: People often suddenly feel drowsy and distressed after eating or drinking, which worsens within a short time and may even lead to death; this is called food poisoning. It refers to someone secretly introducing poisonous substances into food to kill. The clinical manifestation involves the inside of the cheeks or the uvula, initially the size of a sour jujube, gradually enlarging, indicating poisoning.
Prompt treatment leads to recovery; if left untreated for a long time, the poison enters the abdomen leading to death. Upon pulse diagnosis, if the superficial pulse lacks Yang characteristics and is faint, thin, and indistinct, it indicates poisoning.
