Potential effectiveness of the Chinese herbal medicine Yu ping feng san for allergic rhinitis: a systematic review and meta-analysis of randomized controlled trials.

Allergic rhinitis is commonly known as hay fever. It is an allergic response when the nose or eyes come into contact with substances they are allergic to.

Background for this study:

The Chinese herbal medicine formula Yu ping feng san is commonly used for allergic rhinitis. The aim of this study is to evaluate the effectiveness and safety of Yu ping feng san in treating adult allergic rhinitis using the most recent evidence.

Methods of this study:

Seven databases were searched from their inceptions to September 2017. Randomized controlled trials evaluating Yu ping feng san for allergic rhinitis were included.

Results of this study:

Twenty-two randomized controlled trials involving 23 comparisons were included in this review. The combination of Yu ping feng san with pharmacotherapy seemed more effective than pharmacotherapy alone. Further, Yu ping feng san combination treatment seemed more beneficial when it was used for more than three weeks. In addition, Yu ping feng san was well-tolerated for treating adult allergic rhinitis.

Conclusions of this study:

The Chinese herbal medicine formula Yu ping feng san seems beneficial for adult allergic rhinitis. This potential benefit needs to be further evaluated by more rigorous randomized controlled trials.
