Detailed description

Chronic pharyngolaryngitis (CP), also known as chronic pharyngitis, is defined as the inflammation of the pharynx, which is at the back of the throat. CP is a common disease characterized by dry throat, sore throat, pharyngeal itching, dry cough, and difficulty in swallowing. In Western medicine, common treatment regimens for CP include lozenges, antibiotics, lasers, and cryotherapy. However, the above treatment modalities may not be effective, and the disease is likely to bounce back repeatedly. Chinese medicine has been used for the treatment of CP for a long time. Many studies have shown that treatment using Chinese herbal medicine is effective in relieving the symptoms of CP. This study is to evaluate the efficacy and safety of oral Qingyan Lihou Decoction in relieving the clinical symptoms of patients with CP.
