治疗瘴毒引起的发热、烦躁口渴、胸闷神志混乱。表现为外有热象而内有寒象，自发性腹泻、呕吐逆气，手足冰冷。
大附子（炮制，去皮及脐） 人参（去芦头） 炙甘草 炮干姜 白术（去芦头泥土，炒制）
以上药材各等份，水煎煮，温服。如果患者想喝冷水，则让药液冷却后服用。瘴病出现发热、烦躁、口渴，是因为心肺的阳气不能下降所致。自发性腹泻、呕吐逆气、手足冰冷，是因为脾土缺乏阳气、虚寒所致，此方适用于这种情况。寒气盛于体内，用辛热之品治疗。干姜和附子的辛热性质用来治疗内寒。呕吐和腹泻说明脾气虚弱，脾气虚弱的人用参、术、甘草药材的甘味来补益。大附子能引导上焦的阳气进入中焦，这样烦热就会消退，中焦温暖则呕吐和腹泻消除。
治疗瘴疾。症状为呕吐、心腹部胀满疼痛。用人参、白术、干姜、甘草、陈皮、青皮。以上药材各等份，水煎煮，热服，不限时间。
瘴疾多伴有呕吐，是因为脾土虚寒，痰气上逆所致。所以用干姜的辛热来治疗寒邪，用人参、白术、甘草药材的甘温性质来补脾。这同样是理中的方剂，但加入陈皮、青皮的辛味以行散气机，气机下降则痰液下行而呕吐停止。
治疗瘴病数日后，出现发热、腹痛、头目昏沉、四肢疼痛、大便自利、小便或通利或涩滞、或呕吐或咳嗽。
大附子（炮制） 白茯苓（去皮） 白术（炒制） 白芍（炒至黄色）
以上药材加生姜五片，水煎煮，饭前温服。如果小便通利，去掉茯苓。如果大便通畅，去掉白芍，加入干姜。如果呕吐，加入生姜五片。《易简方》说：不下利而呕吐的，去掉附子加入生姜。然而既然去掉了附子只保留三味药，似乎过于平易，应当根据具体情况灵活变通。治疗疾病的方法，本应当远观推测。《活人书》说：太阳病发汗后，出汗但病不解，仍然发热、心悸、头晕，身体筋肉跳动，颤抖想要倒地，用真武汤主治。意思是太阳经伤风，医生借用麻黄，既然病未解，反而造成更重的虚损，所以适宜用白术、附子、芍药之类。又说：少阴病两三天未愈，到四五日出现腹痛、小便不利、四肢沉重疼痛、自发性腹泻、或呕吐或咳嗽、或小便利，这是有水气，用真武汤主治。现在一并赘述于此，以供用药者参考见闻，不至于局限于一方面。瘴病出现头目昏沉、四肢沉重疼痛，是寒湿损伤脾脏的外部证候。腹痛、自利、小便不利，是寒湿损伤脾脏的内部证候。脾脏厌恶湿气，湿气胜则导致濡泄，所以用茯苓、白术的甘味来补脾祛湿。寒气所胜，用辛热治疗。附子、生姜用来补脾，益助阳气而驱除寒气。白芍收敛脾气并消除腹痛，又能停聚诸湿而益生津液，使小便自行排出。然而必须用酒炒至黄色以去除其寒性。名为真武，是因为真武是北方之神，能镇守北方的寒水之气，使其不成为祸害。
Treatment for fever, irritability, thirst, chest tightness, and mental confusion caused by miasma toxins. Manifesting as external heat with internal cold, spontaneous diarrhea, vomiting and regurgitation, and cold extremities.
Radix Aconiti Lateralis Preparata (Da Fuzi, prepared, peel removed, umbilicus removed) Radix Ginseng (Ren Shen, radix removed) Radix Glycyrrhizae Preparata (Zhi Gan Cao) Rhizoma Zingiberis Preparatus (Pao Ganjiang) Rhizoma Atractylodis Macrocephalae (Bai Zhu, radix removed, soil removed, stir-fried).
Equal parts of the above ingredients, decocted in water, taken warm. If the patient desires cold drinks, take the decoction cold. Fever, irritability, and thirst in miasma disease are due to the failure of Heart and Lung Yang to descend. Spontaneous diarrhea, vomiting, and cold extremities are due to Spleen Earth lacking Yang and being deficient-cold; this formula applies. When Cold invades internally, treat with Pungent-Hot substances. The Pungent-Hot nature of Ganjiang and Fuzi treats internal cold. Vomiting and diarrhea indicate Spleen Qi deficiency; for Spleen deficiency, use the Sweet tonifying properties of Renshen, Baizhu, and Gancao. Da Fuzi can guide Upper Jiao Yang into the Middle Jiao, thereby reducing irritability and heat; when the Middle Jiao is warm, vomiting and diarrhea cease.
Treatment for Malaria (Zhang Ji). Symptoms include vomiting, abdominal distension, and pain. Use Renshen, Baizhu, Ganjiang, Gancao, Chenpi, and Qingpi. Equal parts of the above, decocted in water, taken hot, at any time.
Malaria often involves vomiting due to Spleen Earth deficiency-cold causing Phlegm-Qi to rebel upward. Therefore, Ganjiang's Pungent-Hot nature treats Cold, while Renshen, Baizhu, and Gancao's Sweet-Warm nature tonifies the Spleen. This is also a Lizhong-type formula, but Chenpi and Qingpi's Pungency disperses Qi; when Qi descends, Phlegm moves down and vomiting stops.
After several days of treating Miasma Disease, symptoms such as fever, abdominal pain, dizziness and heaviness of the head and eyes, limb pain, spontaneous diarrhea, urination either free or obstructed, vomiting, or coughing may occur.
Radix Aconiti Lateralis Preparata (Da Fuzi, prepared) Poria (Bai Fuling, peel removed) Rhizoma Atractylodis Macrocephalae (Bai Zhu, stir-fried) Radix Paeoniae Alba (Bai Shao, stir-fried until yellow).
Decoct the above herbs with five slices of Shengjiang in water, take warm before meals. If urination is free, remove Fuling. If stool is loose, remove Baishao and add Ganjiang. If vomiting occurs, add five slices of Shengjiang. *Yijian Fang* states: For those without diarrhea but with vomiting, remove Fuzi and add Shengjiang. However, removing Fuzi leaves only three ingredients, which seems too simple; one should adjust according to circumstances. Treatment methods should indeed be considered broadly. *Huoren Shu* states: In Taiyang disease, after inducing sweating, if the condition does not resolve and fever persists with palpitations, dizziness, muscle twitching, and trembling desire to fall, Zhenwu Tang is indicated. This implies that Taiyang wind-strike treated with Mahuang failed to resolve, leading to severe deficiency; thus, Baizhu, Fuzi, and Baishao are suitable. It also states: In Shaoyin disease, if unrelieved after two to three days, progressing to four to five days with abdominal pain, difficulty in urination, heavy and painful limbs, spontaneous diarrhea, vomiting, coughing, or free urination, this indicates Water Qi retention, and Zhenwu Tang is indicated. This is added here for reference, so practitioners do not limit their views to one aspect. Dizziness, heaviness of the head and eyes, and heavy, painful limbs in Miasma Disease are external signs of Cold-Damp injuring the Spleen. Abdominal pain, spontaneous diarrhea, and difficulty in urination are internal signs of Cold-Damp injuring the Spleen. The Spleen dislikes Dampness; excessive Dampness leads to loose stools. Therefore, Fuling and Baizhu's Sweetness tonifies the Spleen and removes Dampness. When Cold prevails, treat with Pungent-Hot. Fuzi and Shengjiang tonify the Spleen, benefit Yang Qi, and dispel Cold. Baishao consolidates Spleen Qi, relieves abdominal pain, retains Dampness to generate fluids, and promotes independent urination. However, it must be stir-fried with wine until yellow to remove its Cold nature. Named Zhenwu because Zhenwu is the deity of the North, capable of suppressing Northern Cold Water Qi to prevent disaster.
