Do you have Throat Coat tea? It's from Traditional Medicinals, and is available at most "natural foods" stores, and also at GNC stores.

Also, I've found that the Yogi Tea "Echinacea Immune Support" tea, brewed and ingested when I first feel the onset of symptoms, tends to stave them off or reduce them. That too should be available at "natural foods" stores, or possibly in the "natural foods" section of whatever local markets are in your area.

A third possibility is zinc lozenges, which are usually available in the vitamin section.

Good luck and hope you feel better soon!
