治温疟，其脉如平，身无寒但热，骨节烦疼时呕者。
白虎汤原方少粳米四合，加桂枝三两，煮服法同。
白虎（加）桂枝治温疟，但热无寒白虎酌。（但热是阳明经热，故用白虎清泄之。）骨节
烦疼加桂枝，（寒在骨节，故加桂枝。）通营泄卫邪斯却。（白虎清气分之热邪，加桂枝一味，
通营泄卫，则白虎并能清营分之热，方义原在心营肺卫立法也。）呕因胃热舌无胎，白虎汤
中姜汁着。（胃热作呕，舌必无胎而口渴，《集验》于白虎汤中加姜汁七匙，后人遵用效。瘅
疟、温疟，俱无寒但热，俱呕，而因不同。瘅疟者，肺素有热，而加外感，为表寒里热之证，
缘阴气内虚，不能与阳相争，故不作寒也。温疟者，邪气内藏肾中，至春夏而始发，为伏气
外出之证，寒蓄久而变热，故亦不作寒也。）
（刘完素《素问病机气宜保命集》 治湿温病两胫逆冷，胸腹满，身疼重，发热汗多，
谵语苦渴，渴不多饮，脉沉细而数者。
苍术（五钱） 石膏（三钱） 知母（一钱五分） 甘草（一钱） 水二盏，煎一盏服。
苍术白虎（汤）治湿温，（立夏后湿土司令，暑湿相搏，病成湿温，不可发汗，治在太
阴。）脉沉细（为湿）数（为热）好推论。身疼胫冷（为湿）胸腹满，（湿热弥漫三焦，气机
不达。）发热汗多苦妄言，（湿上甚为热。热与湿合，郁蒸肌表，则多汗；蒙痹清窍，则苦妄
言矣。）口燥渴而不欲饮，（虽渴而不欲多饮，湿温之义尤明。）刚柔相济此方尊。（方中甘草
佐苍术，知母佐石膏，刚柔相济，用以燥湿清热，不伤脏腑之正气。前白虎加桂枝汤，治寒
化为热，乃太阳阳明同治之方；此苍术白虎汤，治湿化为热，乃太阴阳明同治之方。虽一味
之转旋，其义各有微妙。）
治疗温疟，其脉象看似正常，身体没有恶寒只有发热，骨节烦痛且时常呕吐的病症。
白虎汤原方中减少粳米四合，加入桂枝三两，煎煮和服用方法相同。
白虎加桂枝汤治疗温疟，症状表现为只有发热没有恶寒。（因为但热是阳明经的热邪，所以用白虎汤来清泄。）
骨节烦痛则加入桂枝，（因为寒邪滞留于骨节，所以加入桂枝。）
桂枝能通达营分、泄出卫分之邪气，从而祛除病邪。（白虎汤清气分的热邪，加入桂枝这一味药，能够通达营分、泄出卫分之邪，那么白虎汤也能兼清营分的热邪，方剂的立意原本就在于调理心营和肺卫。）
呕吐是因为胃中有热，舌苔没有厚腻覆盖，在白虎汤中加入姜汁。（胃热导致呕吐，舌苔必然无厚腻且口渴，《集验方》在白虎汤中加入七匙姜汁，后人遵循使用效果显著。）
瘅疟和温疟，都表现为没有恶寒只有发热，都有呕吐，但病因不同。
瘅疟，是患者素来肺中有热，又感受外邪，属于表寒里热的证候，因为阴气在内虚弱，不能与阳气相争，所以不产生恶寒。
温疟，是邪气潜伏在肾中，到了春夏季节才发作，属于伏邪外出的证候，寒邪蓄积久了转化为热，所以也不产生恶寒。
（刘完素的《素问病机气宜保命集》记载：治疗湿温病，症见两小腿逆冷，胸腹部胀满，身体疼痛沉重，发热汗多，说胡话且极度口渴，想喝水但不多喝，脉象沉细而数的情况。
苍术（五钱） 石膏（三钱） 知母（一钱五分） 甘草（一钱），用水两盏，煎至一盏后服用。
苍术白虎汤治疗湿温病，（立夏之后湿气当令，暑湿相互搏结，形成湿温病，不可使用发汗法，治疗重点在太阴脾经。）
脉象沉细（代表湿邪）数（代表热邪），这道理很好推论。
身体疼痛、小腿逆冷（是湿邪所致），胸腹部胀满，（湿热弥漫在三焦，气机运行不通达。）
发热汗多、苦于谵语妄言，（湿气上泛化为热。热与湿结合，郁蒸于肌表，所以汗多；蒙蔽清窍，所以苦于说胡话。）
口燥渴但不想多喝水，（虽然口渴但不愿多饮，湿温病的含义就更加明确了。）
此方尊崇刚柔相济的原则。（方中甘草辅助苍术，知母辅助石膏，刚柔相济，用来燥湿清热，不损伤脏腑的正气。前面的白虎加桂枝汤，治疗寒邪转化为热邪，是太阳经和阳明经同治的方剂；这个苍术白虎汤，治疗湿邪转化为热邪，是太阴经和阳明经同治的方剂。虽然只是一味药的转换，其中的医理却各有微妙之处。）
Treats warm malaria (Wen Nue), where the pulse appears normal, the body has no chills but only fever, with painful and vexing bone joints, and occasional vomiting.
In the original Baibu Decoction (White Tiger Decoction), reduce the glutinous rice by four he, add three liang of Cinnamon Twig (Guizhi), and prepare and administer in the same manner.
Baibu Jia Guizhi Tang (White Tiger Decoction plus Cinnamon Twig) treats warm malaria, characterized by fever without chills. (Since "fever without chills" indicates heat in the Yangming channel, Baibu Decoction is used to clear and drain it.)
For painful and vexing bone joints, add Cinnamon Twig (Guizhi). (Because cold pathogens are lodged in the bone joints, Cinnamon Twig is added.)
It unblocks the Ying (Nutritive) level and drains the Wei (Defensive) level, thereby expelling the pathogen. (Baibu Decoction clears heat pathogens in the Qi level; adding a single herb of Cinnamon Twig unblocks the Ying level and drains the Wei level, allowing Baibu Decoction to also clear heat in the Ying level. The rationale of this formula is originally based on regulating the Heart Ying and Lung Wei.)
Vomiting is due to stomach heat, and the tongue coating is absent/thin; add ginger juice to Baibu Decoction. (Stomach heat causes vomiting, and the tongue must lack a thick coating and present thirst. *Ji Yan Fang* adds seven spoonfuls of ginger juice to Baibu Decoction; later generations followed this usage with good effect.)
Dan Nue (Fever Malaria) and Wen Nue both present with fever without chills and vomiting, but their etiologies differ.
Dan Nue occurs when the lungs have pre-existing heat combined with an external contraction, resulting in a pattern of exterior cold and interior heat. Because Yin qi is deficient internally and cannot contend with Yang qi, chills do not occur.
Wen Nue occurs when pathogenic factors are stored within the Kidneys and manifest during spring and summer; it is a condition of latent pathogens emerging outward. Cold stagnates for a long time and transforms into heat, so chills also do not occur.
(Liu Wansu's *Suwen Bingji Qi Yi Baoming Ji* records: Treating damp-warmth disease presenting with reverse coldness in both lower legs, fullness in the chest and abdomen, heavy and painful body, fever with profuse sweating, delirious speech, severe thirst with little desire to drink, and a deep, fine, and rapid pulse.
Cangzhu (Atractylodis Rhizoma) (5 qian), Shigao (Gypsum Fibrosum) (3 qian), Zhimu (Anemarrhenae Rhizoma) (1.5 qian), Gancao (Glycyrrhizae Radix et Rhizoma) (1 qian). Add two cups of water, decoct to one cup, and take orally.
Cangzhu Baibu Tang (Atractylodes and White Tiger Decoction) treats damp-warmth. (After Lixia [Start of Summer], damp-earth governs; summer-heat and dampness contend, forming damp-warmth. Sweating methods are contraindicated; treatment focuses on the Taiyin Spleen channel.)
A deep and fine pulse indicates dampness, while a rapid pulse indicates heat; this logic is easy to deduce.
Body pain and cold lower legs indicate dampness. Chest and abdominal fullness indicates that damp-heat pervades the Sanjiao (Triple Burner), obstructing Qi mechanism.
Fever, profuse sweating, and distress from delirious speech indicate that dampness rising manifests as heat. When heat combines with dampness and steams the muscle surface, sweating increases; when it clouds the orifices of clarity, delirium ensues.
Mouth dryness and thirst without desire to drink clearly define the nature of damp-warmth.
This formula honors the principle of balancing rigid and soft properties. (In the formula, Gancao assists Cangzhu, and Zhimu assists Shigao; rigid and soft balance each other to dry dampness and clear heat without damaging the righteous Qi of the Zang-Fu organs. The previous Baubu Jia Guizhi Tang treats cold transforming into heat, harmonizing the Taiyang and Yangming channels; this Cangzhu Baubu Tang treats dampness transforming into heat, harmonizing the Taiyin and Yangming channels. Although it involves the substitution of a single herb, the underlying principles are subtle and distinct.)
