A young girl, aged 10, was carried in by her father. She had eye discharge, her mouth was resting on her back, and her limbs were hanging limply, as if she had no sensation. Her father recounted that she had been ill for three days, and around noon and midnight, she would exhibit the aforementioned symptoms, unresponsive to calls, and would wake up as normal after about an hour. Doctors were consulted but could not identify the illness.
The physician examined the symptoms and inquired about the condition, feeling equally perplexed and surprised by the unusual case. After much deliberation, he realized: midnight is the time of the birth of yang, and noon is the time of the birth of yin. These two times are precisely when yin and yang interlock and alternate, and the symptoms of stupor and flaccid paralysis appear. Therefore, treatment should focus on this aspect, but he was at a loss for a formula. After much thought, he considered that Minor Bupleurum Decoction is a remedy that harmonizes yin and yang, so he decided to try two doses. Unexpectedly, her father returned the next day to report that after taking two doses of the medicine, she had suddenly recovered and was planning to return to school to study.
