Derakhshan et al. 51 studied the effect of 15mg dried Ma-al-Shaheer versus fexofenadine in adults with allergic rhinitis (AR) for 21 days, noting AR control was improved in both groups (p<0.001) and symptoms were significantly reduced in both groups, although slightly better for nasal congestion, post-nasal drip, and headache among those receiving the Ma-al-Shaeer treatment.
