Introduction
Sore throat caused by wind-heat is usually accompanied by symptoms such as red and swollen throat, fever, dry mouth, and yellow, thick phlegm. Onions are warm in nature and acrid in taste; consuming them easily aggravates internal heat pathogens, worsening the sore throat and potentially increasing fever and making phlegm thicker and harder to expel. Therefore, onions should be avoided in such cases. For sore throat triggered by an external wind-heat感冒 (common cold), eating onions is not conducive to recovery.
