Overview
Qinghouyan lozenges is a Traditional Chinese Medicine (TCM) therapeutic developed by Shanghai Yusen New Drug Development Co., Ltd. for the treatment of acute pharyngitis and acute catarrhal tonsillitis. It is a solid dosage form (lozenge) derived from the Qinghouyan mixture, a formula traditionally used to treat lung heat with yin deficiency patterns in TCM. The preparation typically contains botanical extracts aimed at clearing heat, detoxifying, and soothing the throat. Clinical evaluation has focused on its efficacy and safety compared to the liquid mixture formulation in adult patients, specifically targeting the TCM pattern of lung heat with yin deficiency.
