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。）

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.)
