Nigella sativa Supplementation to Improve Asthma Control

Nigella sativa oil (NSO) is used traditionally for inflammatory conditions like asthma.[1] The authors in this study investigated the benefits of NSO on clinical and inflammatory parameters of asthma. Capsules of 500 mg twice daily for 4 weeks were used as a supplement in a randomized, double-blind, placebo-controlled trial in asthma patients. The primary outcome was Asthma Control Test score. The results showed that the NSO group showed a significant improvement in mean Asthma Control Test score. The authors conclude that NSO supplementation improves asthma control with a trend in pulmonary function improvement and that this was associated with a remarkable normalization of blood eosinophlia.
