Dr. He Haochen
Common colds can cause dry mouth and throat, typically resulting from infections or inflammation. Following a viral infection, inflammatory mediators trigger hyperemia (increased blood flow) and increased mucus secretion in the upper respiratory mucosa. Saliva and pharyngeal secretions evaporate during respiration, leading to water loss and consequent dryness of the mouth and throat—thus necessitating increased fluid intake. Traditional Chinese herbal medicines—including Jinhua Qinggan Granules, Lianhua Qingwen Capsules, Reyan Ning Granules, Shuanghuanglian Oral Liquid, and Jinlian Qingre Granules—all possess properties that dispel wind-heat and resolve exterior patterns, making them suitable for treating wind-heat type common cold.
