Objective: To observe the therapeutic effect of Jiemin Granules (JMG) on allergic thinitis based on a clinical trial. Method: Sixty cases with allergic thinitis (AR) were randomly divided into two groups equally. i.e. treatment group(TG) treated by JMG and control groups(CG) treated by Loratadine Tablets (LT). Both interventions lasted for two weeks. Then

therapeutic effects were evaluated for the short-term (the 1st day) and the long-term (the 15th day). Result: On the 1st day following the therapy finished

the total effective rate was 90% for the cases of TG

while it was 93% for those of CG

with no statistical significance between them. By the 15th day after the therapy

the improving rate was 83% in TG

in contrast

the rate was only 70% in CG

with marked statistical significance( P ＜0.05)between them. Conclusion: The short-term therapeutic effect of JMG is similar with that of the LT

while the long-term therapeutic effect is better than that of LT. It holds a delaying effect on disease recurrence and is worthwhile for the JMG to be promoted into practical usage in the treatment of AR.
