Qiu**, female, 4+ years old, presented to the clinic with a one-day fever. Physical examination: T39.8C, clear, pharyngeal congestion (++), bilateral tonsils second degree enlargement, purulent discharge visible, heart, abdomen no special. The tongue is red, the coating is thin and yellow, and the pulse is floating. The family complained of occasional chills, no sweating (sweating after taking oral antipyretics), no abnormalities in diet and stool. The parents complained that they had been given fluids for seven days by a Western doctor for “chemical flatness” a month ago, but the fever did not go away for seven days, so they asked for Chinese medicine treatment. The second night, the child was no longer feverish, his spirit was as usual, the redness and swelling of his pharynx had subsided, but a little purulent discharge was still visible. This case experience: there are a few points of vicious cold, there are a few points of superficial evidence, pungent cool medicine with a little pungent warm detoxification medicine, help to sweat to drive out the evil, so as to avoid ice to contain the evil.
