ABSTRACT
BACKGROUND: Asthma is one of the most common chronic respiratory diseases with inflammatory involvement and has a high burden worldwide. This study aimed to determine the effect of Thymus vulgaris (TV) on cough in children between 5 and 12 years old with mild to moderate asthma exacerbation. METHODS: In this randomized, triple-blind clinical trial, 60 children between the ages of 5 and 12 with asthma exacerbations were randomly divided into two groups. The intervention group (n = 30) was given TV powder at a dose of 20 mg/kg every 8 hours, prepared as syrup, along with routine medical treatment for a week, and the control group (n = 30) received only routine medical treatment with placebo syrup. At the end of the week, clinical and laboratory symptoms, and spirometry data were re-recorded for both groups. Finally, the recorded factors were compared and statistically analyzed. RESULTS: The results showed that after the intervention, activity-induced cough reduced, and difference was statistically significant between the two groups (p = 0.042), but the reduction in wheezing and breathlessness had no statistically significant difference. Spirometry data showed a significant difference in forced expiratory volume in 1 second (FEV1) between the two groups after intervention (p = 0.048), but this difference was not significant in FEV1/FVC (forced vital capacity), peak expiratory flow (PEF), and forced expiratory flow at 25-75% of the vital capacity (FEF25-75%). CONCLUSION: The results show that TV syrup may be useful as an adjuvant treatment in children with asthma exacerbations.
