Herbal remedy tested to stop chronic cough from coming back

This study is testing if adding a traditional Chinese herbal formula called Liqin Zhike to standard asthma inhalers works better for a type of asthma that mainly causes a long-lasting cough. Researchers will compare two groups of 118 adults each over 14 months to see which treatment better prevents the cough from returning after stopping medication. The main goal is to see if the combined treatment leads to fewer people having their symptoms come back.
