Spirulina

Spirulina and allergies:

Research has shown that Spirulina has the ability to counteract allergic reactions, anaphylactic response, and has been found to reduce levels of histamine (1,2). Pretreatment with Spirulina has demonstrated reduction of allergic response (2,4), and it was noted that as Spirulina doses increased, there was a greater reduction in histamine levels (2). Spirulina at a dose of 2000 mg oral daily is the dose most commonly used which appears to be effective for allergic rhinitis. Supportive research is provided below.

Spirulina and allergic rhinitis symptoms:

In a study evaluating the effectiveness and tolerability of Spirulina for treating patients with allergic rhinitis, Spirulina at a dose of 2000 mg oral daily for 6 months significantly improved symptoms and physical findings of allergic rhinitis compared with placebo in signs and symptoms of congestion, sneezing, drainage, and itching (3).
