甘草
凡是含有大毒的药物，不能通过口、鼻、耳、目接触人体，否则会导致死亡。主要有两种：一是钩吻，生长在朱崖；二是鸩鸟（一种传说中的毒鸟），又名鹘。其形状像黑色的鹰，生活在海中，羽毛呈黄色。
当钩吻毒侵入人体时，脉象浮大而洪数。发病时怕冷，头部轻微疼痛，干呕，背部感觉紧迫拘急，牙关紧闭，不知不觉咬断舌头，大小便便秘涩滞，面色、眼眶、嘴唇、口角及指甲都呈现青色。
另一种是当孤草毒。发病时牙关紧闭且口干，舌头僵硬无法言语，咽喉部像被锥子或刀子刺割一样疼痛，胸中极度发热，肩胛部位胀满憋闷。若不超过一百天，身体、嘴唇、口角及手背足背都会发青而死。
还有一种是乌头毒。发病时咽喉僵硬且眼睛疼痛，鼻孔闻到臭味，手脚沉重，经常呕吐，腹中闷热，嘴唇和口角发青，面色时而发青时而发红，经过一百天后才会死亡。
大凡肤色黑、骨骼粗大、肌肉丰满的人，因为胃气浓厚，所以能耐受毒性；而消瘦的人则因为胃气薄弱，不能耐受毒性。
治疗中原住民误食毒药，在尚未服药之前，先制定以下方剂：
以上药材用四大碗水，煎煮至剩余两碗药液，滤去药渣。分三次服用。服完后，再进行调理。
另一个方剂：
黄藤（十两，锉碎，岭南地区都有生长）
以上药材用水一斗，煎煮至剩余两升药液，分三次服用。服完后，体内的药毒自然消散。如果长期服用这种藤本植物，中毒自然不会发作。
又一个方剂：
都淋藤（十两，锉碎，岭南地区都有，当地人皆认识）
以上药材用水五大碗、酒两大碗，共同煎煮至剩余三碗药液，分六次服用。依次服完后，药毒随小便排出。十日内需忌食有毒食物。
又一个方剂：
干蓝实（四两） 白花藤（四两，锉碎，以出产隽州的为上品，不可随意食用野葛）
以上药材用水两大碗、酒一大碗，煎煮至剩余一碗药液，滤去药渣。空腹分两次温服，即可痊愈。单用干蓝捣成粉末，用水煎煮频繁服用亦可。
又一个方剂：
都淋藤（五两，锉碎）
以上药材用酒五大碗，一同放入瓦罐中，用蜂蜜密封罐口，用谷壳火从四周烘烤，使其煮沸三到五次。待冷却后取出，温服。常令体内保持有酒气。
治疗不得已情况下，误食了原住民食物的方剂：
使用生甘草一寸，嚼烂吞下。进食者若中了毒，便会立即呕吐出来。这是解中药毒的方法，按照前面的方法治疗即可痊愈。平时可用布袋盛装甘草随身携带。
Medicines with severe toxicity must not come into contact with the mouth, nose, ears, or eyes of humans; otherwise, they are fatal. There are two main types: one is Gouwen (Gelsemium elegans), which grows in Zhuya; the other is Zhen (a legendary poisonous bird), also known as Hu. It resembles a black eagle and lives in the sea, with yellow feathers.
When Gouwen toxin enters the body, the pulse is floating, large, and surging. Upon onset, there is aversion to cold, slight headache, dry retching, tightness and urgency in the back, trismus (lockjaw) with unconscious biting of the tongue, constipation and difficulty in urination, and the complexion, eye sockets, lips, corners of the mouth, and fingernails all turn cyanotic.
Another type is Danggucao poison. Upon onset, there is trismus and dryness of the mouth, inability to speak due to tongue stiffness, pain in the throat as if pierced by awls or knives, intense heat in the chest, and fullness and oppression in the scapular region. If death does not occur within one hundred days, the body, lips, corners of the mouth, and dorsum of the hands and feet will turn cyanotic before death ensues.
Yet another type is Wutou poison. Upon onset, there is stiffness of the throat and eye pain, a foul odor perceived from the nose, heaviness in the hands and feet, frequent vomiting, internal heat and oppression in the abdomen, cyanosis of the lips and corners of the mouth, and a complexion that alternates between cyanotic and red. Death occurs after one hundred days.
Generally, individuals with dark skin, large bones, and plump flesh have thick Stomach Qi and can withstand toxicity. Conversely, thin individuals have weak Stomach Qi and cannot withstand toxicity.
To treat poisoning by local barbarian drugs, before administering any antidote, establish the following prescription:
Shengjiang (Radix Zingiberis Recens, four liang, sliced) Gancao (Radix Glycyrrhizae, three liang, raw, crushed)
Take four large bowls of water, decoct until two bowls remain, strain the dregs, and divide into three doses. After consumption, proceed with conditioning therapy.
Another prescription:
Huangteng (Caulis Tinosporae, ten liang, crushed; available throughout Lingnan)
Take one dou of water, boil until two sheng remain, and divide into three doses. After consumption, the internal drug toxin will dissipate naturally. It is said that regular consumption of this vine prevents poisoning from occurring.
Another prescription:
Dulin Teng (Caulis Dulin, ten liang, crushed; available throughout Lingnan, recognized by locals)
Take five large bowls of water and two large bowls of wine, decoct together until three bowls remain, and divide into six doses. Take them sequentially. After completion, the toxins will be expelled via urine. Avoid toxic foods for ten days.
Another prescription:
Gan Lanshi (Fructus Isatidis, four liang) Baihua Teng (Caulis Hedyotis, four liang, crushed; those from Junzhou are superior; do not casually consume Yege)
Take two large bowls of water and one large bowl of wine, decoct until one bowl remains, strain the dregs, and take two warm doses on an empty stomach. The condition will resolve. Alternatively, grind Gan Lanshi into powder and frequently decoct it in water.
Another prescription:
Dulin Teng (Caulis Dulin, five liang, crushed)
Place in a jar with five large bowls of wine, seal tightly with honey, and roast around the sides using chaff fire until it boils three to five times. Allow to cool, then extract. Take warm. Maintain a sensation of alcohol in the body.
For cases where one has unavoidably consumed food prepared by locals:
Use one cun of raw Gancao (Radix Glycyrrhizae), chew thoroughly and swallow. If the consumer has been poisoned, they will immediately vomit. This treats internal drug poisoning; follow the previous methods for treatment, and the condition will resolve. It is customary to carry Gancao in a small pouch.
