I use this along with echinacea/ goldenseal, vitamin c, zinc and garlic at the first sign of being unwell and it helps tremendously! I used to get bacterial throat infections like strep repeatedly and was on antibiotics over and over for it. Finally decided to do some research and try something different. The last time I took antibiotics was in 1998! This combination I’ve listed works and this brand is high quality! I’ve bought many products from them over the years and have been happy with all of them!
