Water
"Water, air, and cleanness are the chief articles in my pharmacy." ~ Napoleon Bonaparte
"I believe that water is the only drink for a wise man." ~ Henry David Thoreau
"In health and in sickness, pure water is one of Heaven's choicest blessings. Its proper use promotes health. It is the beverage which God provided to quench the thirst of animals and man. Drunk freely, it helps to supply the necessities of the system, and assists nature to resist disease." ~ White, Counsels on Diets & Foods, p. 419.1
