Great, versatile product!
Love this product! Been using it for years. Living where I must thoroughly cleanse produce I use this daily. Although that is the main purpose for me, I know one can use it to gargle or even put on soles of feet when coming down with a cold or other. It is very concentrated. A little goes a long way. And whether this is the reason or not, I rarely get sick. And being a world traveler, I have managed to avoid the digestive issues that plague many travelers.

Great germ killer!
I’ve been using this for years. Just a few drops in my WaterPik each night helps kill germs below the gum line to prevent gum disease. And it also keeps mildew from growing inside the WaterPik’s internal parts. Highly recommended!

"NOT FOR INTERNAL USE" misleading. Great company and product though
I bought this thinking it was a smaller version of the 2fl oz bottle IT IS NOT. This one is a concentrated version and though the label must read "not for internal use", you can and i have. 1-2 drops is equivalent to their other product. Spoke to the company directly and it's just red tape that prevented them from advertising it the way they do the other one. Hopefully they will update their label for consumers when they can. Offered a refund, but now that I know I can use it NO NEED. Thank you!

The best brand for grapefruit seed oil.
Works well to mix with water for nasal spray, water pick, mouthwash and gargle.

It works
It is very strong compared to the regular g.s.e.. You absolutely have to mix it with liquid. Not just for flavor, but because it will burn your throat otherwise. But, it works better than most naturopathic remedies. I take it to tame a chronic sinus infection . It never nocks it out permanently, so its probably not as effective as the stronger class of antibiotics, but it does beat it back to almost nothing. I go from being extremely weak and feeling like I could die to feeling normal and able to function after a day of taking it.
