Ancient herbal remedy tested for modern lung disease

This study is testing whether adding a specific traditional Chinese herbal formula to standard care helps people hospitalized with a sudden worsening of COPD (chronic obstructive pulmonary disease). Researchers will compare two groups of 200 patients to see if the herbal treatment shortens hospital stays, improves breathing, and reduces symptoms. The goal is to see if this complementary approach helps control the disease episode better than standard care alone.
