I use this product every single day
This is excellent stuff. Mitigates cold and flu symptoms very well. I don't need drugs, even over-the-counter, with this stuff.
Xylitol turns out to be a great addition to neti salt. These packets claim to be proportionately mixed for use in neti pots but my experience is they're WAY too strong. I mix a little in with my regular Neti salt. (BTW I use NeilMed neti bottles and salt.) So yes, recommended, but not for use stand-alone.
I bought this with my first neti pot purchase. I have used it a couple times, and really like it. I was already a big fan of the Xlear nasal spray, so I was hopeful. Overall, I think it is great!
