This stuff is very overpriced for what it is. It's just water thats been split so it has a high ph. It's water with a high ph. Thats it. I used it on my pm problem and noticed almost no reduction in pm. It might work better if you use huge huge amounts of it, but then it would just be doing about the same thing as tap water. I'm seeing much better results now from using a product called Green Cure, and Einstein oil.
