Crestone is full of quacks. In a way, all shysters are quacks, in one field or another.
According to a prominent "herbalist":
"Flu! So sorry to hear so many are sick! I highly recommend this [quack herbal blend] for the current wave of flu attacks. This anti-viral blend is hands-down the best herbal blend I've encountered in ages. And I've been an herbalist for ages! Two tablets of this ended several weeks of stomach flu for me, as well. So it's not just for respiratory issues."
