I am a big fan of using tinctures to conquer colds and sore throats, especially at their immediate onset. I tend to use Astragalus tinctures the most, which often include a combination of additional immune botanicals. Aside from that, you can easily find Ban Lan Gen tea at any store that sells Chinese herbs (more powerful if you can get it in tincture). I take these at the slightest sign of a cold or sore throat, or when surrounded by ill schoolmates, and nine times out of ten kicks the bug within a day. If you are already knee-deep into a cold, these will help get over it faster; however, do not expect the same miraculous result .
