Stacey,
I googled the name and found the following formula for Willard water.
"What sets Willard Water apart from other water is that it is catalyst-altered water. This means that the water is mixed with other active ingredients, or catalysts, to improve its function. According to its website, Willard Water is 99.3 percent filtered water and the other ingredients include 87.5 percent sodium metasilicate, 11.5 percent sulfated castor oil, 0.39 percent CAW micelle, 0.23 percent refined lignite, 0.4 percent calcium chloride and 0.4 percent magnesium sulfate."
Bob's NOTE: I'm not a nurse or doctor... this sodium metasilicate is also called liquid glass.
The main characteristic MAY BE that it is very basic and may help adjust the human body's pH to slightly basic a condition that promotes good health if attained naturally by consuming alkaline foods in place of excessive carbohydrates such as white sugar, white flour etc.

Google article: "Sodium metasilicate is not a cleaning agent by itself. It is a VERY strong base. The pH of a 1% aqueous solution is about 13. In moist air it is corrosive to metals like zinc, aluminium, tin and lead, forming hydrogen gas. As a strong base, it reacts violently with acids. A major use is as a builder (a material that enhances or maintains the cleaning efficiency of a surfactant, principally by inactivating water hardness) in soaps and detergents.
It may be used as part of a component in a chemical degreaser, where it would react with fatty acids(animal grease) to form a soap, which is then rinsed away.
Sodium silicate, on the other hand, is an abrasive white powder frequently used in things like toothpaste. It doesn't clean by itself either.
Not something I would recommend for household use."
