病源夫卫气昼行于阳，夜行于阴，阴主夜，夜主卧，谓阳气尽，阴气盛，则目瞑矣，今
热气未散，与诸阳并，所以阳独盛，阴偏虚，虽复病后仍不得眠者，阴气未复于本故也。（出

[Pathogenesis] The Wei-Qi (Defensive Qi) circulates in the Yang aspects during the day and in the Yin aspects at night. Yin governs the night, and the night governs sleep. When Yang Qi is exhausted and Yin Qi is abundant, the eyes close for sleep. Currently, heat pathogens have not yet dissipated and merge with the Qi of the various Yang meridians, causing an exclusive excess of Yang and a relative deficiency of Yin. Therefore, even after the illness has passed, if one still cannot sleep, it is because the Yin Qi has not returned to its original state. (Excerpted from *Shanghan Lun* by Zhang Zhongjing)
[Formula 1] Treats the syndrome of deficiency-heat irritability and insomnia following sweating, emesis, or purgation for cold damage. Severe cases involve tossing and turning and profound inner distress and restlessness. This belongs to the Zhi Zi Chi Tang (Gardenia and Fermented Soybean Decoction) syndrome.

First decoct Zhi Zi until two and a half sheng remain, remove the dregs, add Chi, and continue decocting until one and a half sheng remains. Remove the soybeans. Divide into two doses and take warm. If vomiting occurs, stop taking the remaining dose.
[Formula 2] *Zhou Hou Bei Ji Fang* treats deficiency-heat irritability and insomnia after recovery from severe disease, accompanied by abdominal pain and inner restlessness. Wu Mei Chi Tang (Olive Fruit and Fermented Soybean Decoction).
Ingredients: Xiang Chi (Fragrant Fermented Soybeans, 7 he, wrapped in silk cloth) Wu Mei (Chinese Olive Fruit, 14 pieces, broken open)

First decoct Wu Mei until two and a half sheng remain, add Chi, and continue decocting until one and a half sheng remains. Remove the dregs. Divide into two doses and take warm. If Wu Mei is unavailable, use Si Mu Zhi Zi (Four Gardeniae Fructus) as a substitute.
