I question this doctor's suggestion:
he writes, "It's not conventional to suggest astragalus, echinacea, elderberry and vitamin C. Adequate vitamin D levels are crucial, too."
Implying that elderberry and echinacea would be good things to take to prevent/or if one aquired h1n1. But I've read that these things can set the body off on a cytokine storm:
I linked to him, though, because I thought it was interesting he said it's good to get a "mild" form now (vs. a possibly more virulent form later.)
