Methodology
Double-blind, placebo-controlled trial of oral spirulina versus placebo in patients with allergic rhinitis; symptom scores and physical findings including nasal discharge, sneezing, congestion and itching.
Key Findings
In this double-blind, placebo-controlled trial of spirulina in patients with allergic rhinitis, spirulina significantly improved symptoms and physical findings compared with placebo (p < 0.001), including nasal discharge, sneezing, nasal congestion and itching. The supplement was reported as well tolerated. The authors conclude spirulina is clinically effective versus placebo but call for work to clarify the mechanism.
Conclusions
Spirulina consumption significantly improved the symptoms and physical findings compared with placebo (P < 0.001) including nasal discharge, sneezing, nasal congestion and itching. Spirulina is clinically effective on allergic rhinitis when compared with placebo.
Limitations
Single-centre trial with a briefly reported abstract that gives no effect sizes, baseline comparability data or funding details; the mechanism of effect is unexplained and the result has not been widely replicated.
Supplements Studied
Spirulina consumption significantly improved the symptoms and physical findings compared with placebo (P < 0.001) including nasal discharge, sneezing, nasal congestion and itching. Spirulina is clinically effective on allergic rhinitis when compared with placebo.
