NCT07787507

Brief Summary

This randomized, double-blind, placebo-controlled study evaluated Withania somnifera root powder as a complementary therapy in adults with moderate-to-severe persistent asthma receiving standard asthma treatment. Participants were assigned to standard treatment alone, standard treatment plus placebo, or standard treatment plus Withania somnifera root powder for 10 weeks. Lung function, asthma control, quality of life, systemic oxidative stress, and inflammatory and allergic biomarkers were assessed before and after the intervention to evaluate the potential additional benefits of Withania somnifera in asthma management.
