Spring Allergy Support

SPRING IS COMING AND SO IS THE POLLEN! Need some help supporting your immune system when everything is coated in yellow? Here are 3 evidenced based support protocols that may help manage symptoms associated with allergic rhinitis. Probiotics Probiotics ~10 billion CFU per day ( Luo 2022 ) A 2022 meta-analysis of 28 studies revealed that probiotics significantly alleviated allergic rhinitis symptoms, improved Rhinoconjunctivitis Quality of Life Questionnaire scores, and increased the T helper cell 1 (TH1) to T helper 2 (Th2) ratio, but did not lead to significant changes in overall or specific IgE levels compared to the control group. ( Luo 2022 ) Another meta-analysis of 22 randomized, double-blind, placebo-controlled studies indicated significant clinical benefits of probiotics, particularly with  Lactobacillus paracasei  strains, showing improvements in symptoms, quality of life scores, and immunologic parameters, with notable reductions in nasal and ocular symptoms and improvement in TH1/TH2 ratio compared to placebo. ( Güvenç 2016 ) Probiotics containing  Lactobacillus  and  Bifidobacterium  may prevent allergy recurrences, reduce symptom severity, and enhance the quality of life in allergic rhinitis patients by modulating the immune system through the induction of cytokine production, leading to a dominant TH1 response and balancing the TH1/TH2 ratio. ( Nogueira 2011 ) Butterbur Petasites officinalis  (butterbur) 8 mg eremophilan type sesquiterpenes (petasin) 3–4 times per day for 2 weeks ( Schapowal 2002 )( Schapowal 2005 ) One study demonstrated that butterbur and cetirizine were equally effective in improving SF-36 scores and global improvement scores on the clinical global impression scale, with both treatments being well tolerated. However, in the cetirizine group, most reported adverse events were associated with sedative effects, suggesting that butterbur may be a suitable alternative for seasonal allergic rhinitis treatment when avoiding sedative effects is necessary. ( Schapowal 2002 ) In another study, butterbur Ze339 was shown to be an effective and well-tolerated treatment for intermittent allergic rhinitis in a dose-dependent manner. The best results were seen in the high-dose group, which received one tablet containing 8 mg of total petasin three times daily, versus the low-dose group receiving one tablet twice daily. ( Schapowal 2004 ) Butterbur extract was significantly more effective than placebo in alleviating symptoms of intermittent allergic rhinitis. Notably, Butterbur Ze 339 was as efficacious as fexofenadine, an antihistamine. ( Schapowal 2005 ) Quercetin and Stinging Nettle Quercetin and  Urtica dioica  (stinging nettle) Quercetin: 200 mg per day minimum for at least 8 weeks ( Yamada 2022 ); Stinging nettle: 150 mg per day for at least 1 month ( Bakhshaee 2017 ) Quercetin may be helpful for relieving the symptoms of pollen allergies, including itchy eyes, sneezing, runny nose, and sleep issues. ( Yamada 2022 ) In one study investigating the effects of enzymatically modified isoquercitrin (EMIQ), the group taking EMIQ consistently had significantly lower ocular symptom and medication scores compared to the placebo group. Notably, during weeks five through six, ocular symptoms and congestion scores were significantly reduced. ( Hirano 2009 ) In a randomized, double-blind, placebo-controlled trial, the total ocular and ocular itching scores for the EMIQ group were significantly lower compared to the placebo group. ( Kawai 2009 ) One study aimed to assess the efficacy of  Urtica dioica  in managing allergic rhinitis symptoms through a randomized trial demonstrated that stinging nettle has positive effects in the management of allergic rhinitis. ( Bakhshaee 2017 ) In a double-blind. randomized study involving 98 participants with allergic rhinitis,  Urtica dioica  showed higher global assessment ratings compared to placebo, although only slightly higher ratings were observed in daily symptom diaries.
