By far the best Silver drops and brand we have ever tried. This stuff is a major staple in our house hold when it comes to health supplements. We use it for everything: eye infections, cuts, scrapes, even putting it in the water when sick. The best one is we put it in nose sprayers and anytime you start to feel like you are getting sick, you do a few sprays up each nostril and it usually goes away pretty quickly. I personally used to get sick after flying in a airplane a lot, but now I put a few sprays of this up the each nostril when I get to the place we’re staying and have not had a problem since. This is an amazing supplement and I highly recommend everyone have some.
