So, the NY times article goes a little like this: Study Says Echinacea Has No Effect on Colds. I cannot count the number of times I've caught a cold and listened through a miserable haze to hear someone telling me, with evangelical intensity, to TAKE THE ECHINACEA. Forgive me if I feel silly spending $7.00 on a sketchy brown bottle with a picture of a thistle on it. I actually have very little faith in thistles. I don't know what it is about echinacea that makes people act so passionately on its behalf. O ye of little faith!
