Good - but potent

Posted by iHerb Customer on Oct 25, 2014 | Verified Purchase

I think the extra ingredients in this may cause stomach upset (at least for me) - but with food it was better. Seemed to clear things up for me. Good for infections.

Thanks for your feedback!

Good for preventing colds.

Thanks for your feedback!

i want the plain kind! no extras!

I don't want the echinacea (immune-booster), causes me inflammation. The artemesia annua that they added is useless, because it's an oxidant, only works as an oxidant on empty stomach, and i take these pills with anti-oxidants and food!

Thanks for your feedback!
