Add one ounce of this concentrate to a gallon of pure water to make water more absorbable, enhancing hydration; drinking one glass is like drinking about three glasses of plain water. I always recommend it to my clients who are athletes, who need urinary system support, or who are in a situation where they need to super-hydrate, like when they are dealing with a respiratory or digestive infection. Used topically, my kids called it "owie juice"; it tremendously accelerates healing, especially of burns, minor cuts and abrasions. 8 ounce bottle.
