I've been taking the OPC-3 for about 4-5 months now and have had tremendous allergy relief. I'd been having some pretty severe respiratory distress and congestion when I began taking it. Within a week ALL the symptoms were gone. We've also had success in alleviating sinuses, headaches, colds, etc. I've never taken anything like it.
Good Luck!
