The Chinese herbal formula Ding Chuan Tang was put to the test in a randomized, double-blind clinical trial.
Ding Chuan Tang in Chinese herbal medicine has been used for chronic bronchitis and asthma with symptoms such as coughing, wheezing, labored breathing, phlegm, and fever. It was given to 28 stabilized, mild to moderate persistent asthmatic children, aged 8-15 years, for a period of 12 weeks.
The results showed that Ding Chuan Tang significantly improved airway hyper-responsiveness in these children as compared to other 24 children given a placebo.
