'We advise tea for the whole nation and for every nation. We advise men and women to drink tea daily; hour by hour if possible; beginning with ten cups a day; and increasing the dose to the utmost quantity that the stomach can contain and the kidneys eliminate.'

-Dr. Cornelius Buntekuh, Medizinischen Elementarlehre, Dutch physician in the pay of the Dutch East India Company, c. 1680
