I have taken it during cold and flu season in the ER and it seemed to really help me not to catch those. Or if I seemed to be coming down with either, I took it as directed on the bottle and the symptoms seemed to go away. Anyway, I liked it.
I love this stuff!! And I am the cynical one :-)
Everyone in my family came down with a virus, except for me. Was it the airborne? I don't know, but I was up close and personal with everyone and all got sick except me.
I've tried it. It has nipped the beginning stages of a cold last week. Not sure if it was just a placebo effect, but hey , no cold this week.
I gave some to my daughter today, as some kids in her class are sick. Time will tell if she does fall ill.
