Mr. Liang, in the third month of the year Xin Mao, suffered from alternating chills and fever, headache, a bitter taste in the mouth, thirst, and a slight cough. After taking Minor Bupleurum Decoction, all symptoms subsided, except for the inability to defecate for six or seven days, and the recurrence of headache with tidal fever in the late afternoon. He consulted me, and I prescribed a dose of Minor Bupleurum Decoction Plus Sodium Sulfate. After taking it, the pain disappeared as if by magic.
