Zai Zao San再造散
Renewal Powder
Ingredients10 herbs
Indications
Wind-cold in the exterior with yang qi collapsed: the fever is slight, the chills are heavy, and repeated diaphoresis has failed because the yang that drives a sweat is gone.
Clinical Manifestations
- Cold that will not break despite repeated sweating attempts
- Severe chills with a weak, hollow pulse
- Cold in an elderly or convalescent patient
- Pale, exhausted patient with fever and no sweat
Health Categories
Modern Applications
Common adjustments
- Blood deficiency as well — add Dang Gui 当归 and Shu Di Huang 熟地黄
- Summer months or a warmer patient — classically a little Shi Gao 石膏 is added to offset the warmth
- Cough with thin phlegm — add Xing Ren 杏仁 and Zi Su Ye 紫苏叶
Contraindications
Not for wind-heat or any heat pattern, and not for exterior cold in a robust patient — supporting yang there would hold the pathogen in. Fu Zi must be the processed form and decocted first and long; numbness of the mouth or tongue, palpitations or nausea means stopping immediately and seeking care.
For licensed practitioners’ reference only — not a self-treatment guide.
Pregnancy
Contraindicated in pregnancy. Fu Zi and Xi Xin are both present and Chuan Xiong moves blood; a depleted pregnant patient with an exterior pattern needs an entirely different approach, built without these herbs.
