上以知母连根叶捣作末服之。亦可服水捣取汁饮二升，夏月出行，多取此屑自随，欲入
水，先取少许投水上流便无畏，兼辟射工。亦可和水作汤浴之，甚佳。
上用生苍耳七个，白矾两皂子许，嚼涂咬处，须男子嚼之，余药敷肿处。
解砒毒等。
上用白扁豆，不以多少为细末，入青黛等分，细研，再入甘草末少许，巴豆一枚，去壳
不去油，别研为细末，取一半入药内，以砂糖一大块，水化开，添成一大盏饮之，毒随利去
后，却服五苓散之类。
解药毒
蓝根（锉，一握） 芦根（锉，一握） 绿豆（研，一分） 淀脚（研，二合）
上先将二根以水一碗，煎至七分去滓，次入后二味和匀，分三服，或一二服利下恶物，
不用再服。
凡中药毒，即令食生黑豆数粒，食之闻腥者即非虫毒也。若是吐逆躁烦，服药须极冷，
即解也。
甘草（一两，生用） 白面（半两，生用） 延胡索（一两）
上锉细，每服半钱，水一盏，煎至六分，去滓放冷，细细呷之。
上为生姜汁或干姜汁服之良。唐崔魏公季 夜暴亡，有梁新闻之，乃诊之云∶中食毒。
仆曰∶常好食竹鸡，竹鸡多食半夏苗，必是半夏毒，命生姜捩汁而灌之活。浙人王夫人，忽
日面上生黑斑数点，曰久满脸俱黑，遍求医治，不效。忽遇一草泽医人云∶夫人中食毒，治
之一月平复。后求其方，止用生姜汁服之。问其故，云∶食斑鸠，盖此物常食半夏苗，中毒
以姜解之。
取知母（Anemarrhenae Rhizoma），连根带叶捣碎成粉末服用。也可以用水捣烂取汁饮用两升。夏季外出时，多携带这种药屑随身备用，想要下水时，先取少许撒在水流上游，便无畏惧，同时也能驱避射工虫（一种水中毒虫）。也可以将药屑与水混合煮汤沐浴，效果很好。
取生苍耳（Xanthii Fructus）七个，白矾（Alumen）约皂角子大小的量，由男子嚼碎后涂抹在被咬伤的部位，其余药物敷在肿胀处。
用于解除砒霜等中毒。
取白扁豆（Dolichoris Semen），用量不限，研成细末，加入青黛（Indigo Naturalis）等量，细细研磨均匀，再放入少许甘草（Glycyrrhizae Radix et Rhizoma）末，以及一枚巴豆（Crotonis Fructus），不去壳也不去油，单独研成细末。取这一半的巴豆末加入前面的药粉中，用一大块砂糖加水化开，调和成一大杯饮下。毒素随大便排出后，再服用五苓散（Wuling San）之类的方剂。
解除药物中毒。
蓝根（Isatidis Radix，锉碎，一握的量） 芦根（Phragmitis Rhizoma，锉碎，一握的量） 绿豆（Vigna radiata Semen，研碎，一分的量） 淀脚（Indigo Naturalis Residue，研碎，二合的量）
先将两种根部药材用一碗水煎煮至七分满，滤去药渣，然后加入后两种药材混合均匀，分三次服用。如果服一二剂后排出恶浊之物，就不必再服。
凡是中药物中毒，立即让患者吃几粒生黑豆（Sojae Semen Nigrum），吃了之后闻到腥味就不是虫毒。如果出现呕吐、逆气、烦躁不安的症状，服药必须极冷，才能解毒。
甘草（一两，生用） 白面（半两，生用） 延胡索（Corydalis Rhizoma，一两）
切碎，每次服用半钱，用水一盏，煎至六分，滤去药渣放凉，慢慢小口饮用。
用生姜汁或干姜汁服用疗效好。唐代崔魏公季夜间突然死亡，梁新得知后，为他诊脉说：“这是中了食物毒。”仆人问：“他平时喜欢吃竹鸡，竹鸡多吃半夏苗，一定是半夏中毒。”于是命人取生姜汁灌服，救活了病人。浙江人王夫人，忽然脸上生出几点黑斑，后来满脸变黑，遍求医治无效。忽然遇到一位民间草泽医生，说：“夫人是中了食物毒。”治疗一个月后康复。后来询问其方子，只用生姜汁服用。问其原因，医生说：“吃了斑鸠，因为这种鸟常食半夏苗，中毒后用姜来解。”
Take *Anemarrhenae Rhizoma* (Zhimu), including roots and leaves, pound into powder, and take orally. Alternatively, pound with water to extract juice and drink two sheng (approx. 400ml). In summer when traveling outdoors, carry this powder with you; before entering water, sprinkle a small amount upstream to dispel fear and ward off the "Shegong" insect (a venomous aquatic creature). It can also be mixed with water to make a decoction for bathing, which is very effective.
Take seven fresh *Xanthii Fructus* (Cang'er) and alum (Bai Fan) equivalent to the size of a soap pod. Chew these by a man and apply to the bite site; apply the remaining medicine to the swollen area.
To resolve arsenic poisoning and similar conditions:
Take *Dolichoris Semen* (Baibian Dou), quantity as needed, grind into fine powder. Add an equal amount of *Indigo Naturalis* (Qingdai), grind finely together. Then add a small amount of *Glycyrrhizae Radix et Rhizoma* (Gancao) powder and one *Crotonis Fructus* (Badou), keeping the shell and oil intact, and grind separately into fine powder. Take half of this *Crotonis Fructus* mixture and add it to the main powder. Dissolve a large piece of rock sugar in water, mix with the powder to form a large cupful, and drink. After the toxin is expelled through diarrhea, subsequently administer formulas such as Wuling San (Five-Ingredient Powder with Poria).
To resolve drug toxicity:
*Isatidis Radix* (Lan Gen), chopped, one handful; *Phragmitis Rhizoma* (Lu Gen), chopped, one handful; *Vigna radiata Semen* (Lvdou), ground, one fen (approx. 3-5g); Indigo residue (Dian Jiao), ground, two he (approx. 200ml).
First, decoct the two root materials in one bowl of water until reduced to 70%, then filter out the dregs. Next, add the latter two ingredients, mix evenly, and divide into three doses. If foul matter is discharged after one or two doses, do not take further doses.
For any herbal toxicity, immediately have the patient eat several raw black soybeans (*Sojae Semen Nigrum*). If a fishy smell is perceived upon eating, it is not insect toxicity. If symptoms include vomiting, regurgitation, restlessness, and irritability, the antidote must be taken extremely cold to resolve the toxicity.
*Glycyrrhizae Radix et Rhizoma* (Gancao), one liang, used raw; White flour (Baifan), half liang, used raw; *Corydalis Rhizoma* (Yanhusuo), one liang.
Chop finely. For each dose, take half qian (approx. 1.5-3g), decoct in one zhan (approx. 200ml) of water until reduced to 60%, filter out dregs, let cool, and sip slowly.
Using fresh ginger juice or dried ginger juice orally is beneficial. During the Tang Dynasty, Duke Cui Wei's son died suddenly at night. Liang Xin learned of this and diagnosed him, stating: "He has ingested food poison." The servant asked: "He often eats bamboo chickens, which feed on *Pinelliae Rhizoma* (Banxia) seedlings; it must be *Pinelliae* toxicity." Thus, ginger juice was extracted and forced down his throat, saving his life. Lady Wang from Zhejiang suddenly developed several black spots on her face, which eventually covered her entire face. Seeking medical treatment everywhere proved ineffective. Suddenly, a folk physician encountered her and said: "You have ingested food poison." After one month of treatment, she recovered. When asked for the prescription, he replied that only ginger juice was used. When questioned why, he explained: "She ate turtle doves, which often consume *Pinelliae* seedlings. The toxicity is resolved using ginger."
