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

【病机分析】卫气在白天运行于阳分，在夜晚运行于阴分。阴主夜间，夜间主睡眠。当阳气耗尽、阴气旺盛时，人就会闭上眼睛入睡。如今热邪尚未消散，与诸阳经之气相并，导致阳气独盛，阴气偏虚。因此，即使病后仍然无法入睡，是因为阴气未能恢复到其本源状态。（出自《仲景伤寒论》）

[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 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.
