Nie, female, 38 years old. Suffering from sore throat, dryness, hoarseness, or even complete loss of voice. The course of the disease has lasted for half a month. She had previously consulted a Western doctor and took "watermelon frost," Chinese medicinal lozenges, and Cefradine VI, as well as several doses of Chinese medicinals for clearing heat, removing toxins, benefiting the pharynx, and reducing swelling, but none showed significant effect.

At the time of consultation, she could not speak and communicated by writing, complaining of sore and dry throat, drinking little water, and having difficulty sleeping and eating. Examination of the throat revealed obvious congestion in the palatopharyngeal arch and tonsils, and the tongue texture was slightly red. Considering wind-heat attacking upwards, Wenbing Tiaobian Yinqiao Puff-Ball Powder was used, and the symptoms improved after taking the medicine, but soon returned to the original state. Later, upon further questioning, the patient reported coughing with little phlegm, feeling something in the throat, and feeling better after coughing. There was slight chest tightness, slightly poor appetite, normal bowel movements, and unfavorable Jingshui. It was diagnosed as phlegm heat stagnation in the throat, and the treatment was changed to Vinegar Decoction from "Cold-Damage Disease Treatise."

The patient was instructed to take one large egg, make a small hole at the pointed end, remove the yolk and a little egg white, crush 5 grams of Pro Formula Pinellia and put it into the egg, fill it with vinegar, place it on a wire ring, roast the eggshell over fire to boil the vinegar, remove the residue, and slowly swallow it while warm, twice a day. After 2 doses, the pain decreased and the voice returned, and after 5 doses, all symptoms disappeared and speech returned to normal.
