What is the scallion and ginger water fever-reducing method?
Ginger-scallion water cannot serve as an effective medical treatment for fever. Its warming properties may only relieve mild chills, but it is unable to reduce body temperature or address the underlying cause of a fever. Fever is the body's immune response to infections and other abnormalities. If body temperature remains above 38.5°C or is accompanied by severe symptoms such as headache or vomiting, prompt medical attention is necessary.

From a compositional standpoint, scallions contain volatile oils and ginger contains gingerol. Drinking a decoction made from these ingredients may produce a brief sensation of warmth, but it has no direct antipyretic effect. Moreover, their warming nature might exacerbate internal heat and could potentially worsen fevers caused by wind-heat type colds, possibly delaying proper treatment.
Fever management should focus on hydration and heat dissipation: drink plenty of warm water to promote metabolism, maintain good indoor ventilation, and wear loose, breathable clothing to aid in cooling. Diet should be light and easy to digest, avoiding spicy and warming foods, while ensuring adequate rest to support the immune system in fighting off pathogens.
