Throat Sprays

I asked about sickness-related throat care at class last night and she highly recommended throat spray...not just during sickness...but as overall throat health care maintenance. She suggested Zand brand, which she said is only available at one store in the area out in Middleton. I've been using Herb Etc's Singer's Saving Grace for a long while, and while she said this was good too, she warned against using sprays with propolis, because it is a numbing agent.
