These WORK!
Size: 60 Count (Pack of 1)
I purchased these two bottles ago for help with dealing with a bad case of oral thrush caused by a couple rounds of powerful antibiotics and fluconazole (rebound?) for a bad UTI and resulting yeast infection. Oil pulling, mouthwashes, salt water rinses all helped, but this put me over the top. I also take a candida killing herbal supplement as well as a variety of probiotics. I appreciate the mint is very mild (these are NOT breath mints which only mask the problem) and dissolve them slowly in my mouth at bedtime along with another during the day. I am also sure to not put anything else in my mouth for a good long time after so the pb’s can do their magic. i believe the thrush is mostly gone, but I still have some residual tingling and burning from time to time. These, along with good oral cleansing practices, help tremendously. I now order them regularly. They also make your breath fresh, naturally. Great product. Highly recommend!

Taste
Size: 30 Count (Pack of 1)
I ordered this a week ago, and it seems to taste like smoke or an ashtray. It was not a pleasant taste at all, I expected it to be great with all the other good reviews. Unfortunately that was not the case for me.

effective for dry mouth during sleep
Size: 16 Fl Oz (Pack of 1)
I tried this in lieu of my usual Biotene. It works just as well and you can't beat the price savings. I mouth breathe during sleep and this helps keep my mouth moist. Only thing I wish the cap were not a safety cap as I find it a bit difficult to open, so I transfer the contents to an old Biotene bottle. Yet I certainly understand the purpose of a safety cap. On my 2nd bottle of this now and if the price stays competitive this is my go-to rinse.
