Question
A child has been suffering from a persistent cough for a year, with periods of improvement and worsening, accompanied by a hoarse voice and phlegm. Various medications have been used for treatment, but complete recovery has not been achieved. The recent diagnosis at the Provincial City People’s Hospital is cough-related asthma, with an CT report showing increased and blurred lung field textures. Is this condition easy to treat? How serious is the CT report situation? What herbal teas can be consumed for health maintenance in everyday life?
