Effects of a Novel Barley-Based Formulation on Allergic Rhinitis: A Randomized Controlled Trial

Endocr Metab Immune Disord Drug Targets. 2019;19(8):1224-1231. doi: 10.2174/1871530319666190306100611.

Abstract

Objective: Current treatment options for Allergic Rhinitis (AR) may have their own limitations and side effects. This study aimed to investigate the effects of Ma-al-Shaeer (MS), a novel natural formulation based on Hordeum vulgare, in the treatment of AR compared with Fexofenadine (FX).

Methods: A total of 77 patients with AR were divided into two groups: MS group (n=38) and FX group (n=39). The first group received 15 g of dried MS powder, and the second group received 60 mg of FX twice daily for 14 days. At baseline (week zero) and after the 14-day treatment period (week two), both groups were evaluated for sneezing, rhinorrhea, nasal congestion, nasal itching, post nasal drip, eye, throat, or ear symptoms, headache, cough, mental function, quality of life scores, blood eosinophil count and total IgE levels. Rhinitis control assessment tests were conducted at week zero and again at one week after cessation of treatment (week three) in both groups.

Results: All symptoms of AR except cough were significantly reduced in both groups; for nasal congestion, post nasal drip, and headache, the MS treatment was found to be superior. Rhinitis control was significantly increased after treatment in both groups (p value < 0.001). Both drugs significantly reduced total IgE levels. There was no significant change in eosinophil count in either group.

Conclusion: MS formulation based on H. vulgare may be an effective treatment for AR. Further studies are needed to confirm the effect of MS as an alternative treatment in AR.
