The last post referred to pycnogenol, astragalus and silymarin for seasonal allergies. This week it's probiotics. Two studies came up both involving children.
When examined after 3 months of probiotic treatment, the Lactobacillus salivarius-treated group reported reduced nasal and eye symptoms compared with the UT (untreated) group.
The other study added the probiotic (Lactobacillus johnsonii EM1) to Levocetirizine (antihistamine) to 63 children. This study showed that Levocetirizine plus the probiotic was more effective than the antihistamine alone and that the effect persisted for at least 3 months.
With the many health benefits that have been shown lately about probiotics it might be worth trying a board spectrum probiotic, including natural probiotic foods or make your own fermented food this spring and eat some everyday. Dr Mercola has a good article.
Effect of Probiotics on Allergic Rhinitis in Children
One-hundred and ninety-nine atopic children with allergic rhinitis were randomly assigned to 4 × 109 colony forming units/g of Lactobacillus salivarius or placebo as a powder mixed with food or water for 12 weeks. The lactobacillus group had a reduction in rhinitis symptoms and allergy medication use.

Adding Lactobacillus johnsonii EM1 to Levocetirizine for Treatment of Perennial Allergic Rhinitis in Children
Sixty-three children (7-12 years) who had moderate to severe perennial allergic rhinitis (PAR) were randomized to 2 crossover treatment regimens of levocetirizine with Lactobacillus johnsonii EM1 (Lj EM1) (group 1) or levocetirizine alone (group 2) for 12weeks; subsequently treatments were reversed for another 12 weeks. Both groups had improved total symptom score (TSS) compared to the run-in period and the levocetirizine with Lactobacillus johnsonii group was more efficacious than group 2 at week 4,8 and 12. During the second phase the levocetirizine with Lactobacillus johnsonii showed continual and progressive improvement while the levocetirizine only group, did not. The 24-week, 2-phase, crossover treatment program showed that levocetirizine plus Lj EM1 was more effective for PAR than levocetirizine and that this difference persisted for at least 3months after discontinuation of Lj EM1.
