Since moving to Massachusetts, I discovered Zarbee's and take it every time I start getting a scratchy throat. It's been such a lifesaver. It doesn't always totally prevent a cold, but it definitely shortens them. With the weather all over the place this winter, I've been more prone to illness than usual, so this has been a game changer. I really like the flavor of both the day and nighttime drinks, and I find them to be effective (my colds used to drag on for a week or more, with symptoms lingering well after that, but the two colds I've had were pretty mild and I was all better within a week). All natural without any questionable chemicals or weird tastes AND it actually works. These really do soothe my throat, they've become a staple for me.
