Your cold is gone, but why is the cough still there three weeks later? The cause may not be limited to the lungs—it may involve the nose, acid reflux, airway hypersensitivity, medicines, or other factors. This book explores persistent cough through modern medicine and Traditional Chinese Medicine, with a practical focus on what you can do: UK OTC options, food therapy for different cough patterns, TCM approaches, and when it is time to see a doctor.
