Wherever a household's dwelling is clean, free of dust and spider webs, it indicates the presence of Gu poison (Gu toxin). Do not associate with them to avoid harm.
Another prescription: When about to consume tea, water, vegetables, or rice, strike the chopsticks against cups and bowls, and ask the host, "Is there really Gu poison in the food?" Once exposed, one can avoid harm.
Another prescription: Bring raw garlic cloves when eating. If Gu poison is present, it will be vomited out immediately; if not vomited, death ensues. The host, fearing retribution, will dare not administer the poison.
Another prescription: Take large water chestnuts (Dioscorea cirrhosa), any quantity, slice them, dry them, and grind into powder. Each morning on an empty stomach, take two qian (approx. 6-7g) mixed with plain boiling water. This divine prescription ensures safety when entering homes harboring Gu poison.
Another prescription: For those who do not drink alcohol, Gu poisoning is mild and easy to treat; for drinkers, it is severe and difficult to treat. Gu poison often occurs in border regions with smoky miasma. In areas with such miasma, drinking alcohol helps dispel the pathogenic factor. Therefore, drinking is necessary. Ideally, drink more at home and less when traveling.
Use sharp-edged porcelain shards or tiles to prick the forehead, the area between the eyebrows, or both arms until one sheng (approx. 500ml) of blood is discharged, which resolves the condition. Bright red blood in large quantities indicates a mild case; dark purple blood in small quantities indicates a severe case.
Another prescription: Atractylodis Rhizoma (Baizhu), Citri Reticulatae Pericarpium (Chenpi), Poria (Fuling), Pinelliae Rhizoma (Banxia), Gardeniae Semen (Zhiren), Crataegi Fructus (Shanzha), and Massae Medicatae Fermentatae (Shenqu) each 1 qian (approx. 3g); Forsythiae Fructum (Lianqiao), Peucedani Radix (Qianhu), and Atractylodis Rhizoma (Cangzhu) each 0.7 qian (approx. 2g); Raw Glycyrrhizae Radix et Rhizoma (Sheng Gancao) 0.4 qian (approx. 1.2g); add Zingiberis Rhizoma Recens (Shengjiang) as a guide. Decoct and take several doses for miraculous efficacy. This is also effective for travelers suffering from maladaptation to local conditions.
Another prescription: Consume seven slices of raw garlic and seven slices of cooked garlic together. After a short while, abdominal borborygmus may occur, followed by hematemesis or bowel movement, leading to recovery.
In provinces such as Yunnan, Guizhou, and Liangguang, if a sudden fragrant odor strikes the nose, it is Miasma (Zhang Qi). Do not inhale it under any circumstances to avoid illness.
Another prescription: In areas with miasma, avoid overeating. Drink several cups of wine daily; even non-drinkers should force themselves to drink slightly to dispel the miasma. There were three people walking early in mountain fog: one died, one fell ill, and one remained unharmed. It was later discovered that the deceased had eaten too much, the sick person had an empty stomach, and the healthy one had drunk alcohol.
