Dr. Prat, in his _treatise of mineral waters_, shews it to be his judgment, that, if people would accustom themselves to drink water, they would be more free from many diseases; such as tremblings, palsies, apoplexies, giddiness, pains in the head, gout, stone, dropsy, rheumatism, piles, and such like: which diseases are most common among them that drink strong drinks, and which water generally would prevent. Moreover, he saith, that water plentifully drank, strengthens the stomach, causeth an appetite, preserves the sight, maketh the senses lively, and cleanseth all the passages of the body, especially those of the kidneys and bladder. [Sidenote: _Health to procure by Water._] ’Tis also said by Dr. Duncan, in his _treatise of hot liquors_, that, when men contented themselves with water, they had more health and strength; and that at this day those who drink nothing but water are more healthy, and live longer, than those who drink strong liquors, which raise the heat of the stomach to excess, whereas water keeps it in a due temper. And he adds in another part of the book, that by hot liquor the blood is inflamed; and such whose blood is inflamed, live not so long as those who are of a cooler temper; a hot blood being commonly the cause of fluxes, rheums, ill digestion, pains in the limbs, head-ach, dimness of sight, and especially of hysteric vapours. He also imputes the cause of ulcers to a hot blood, and declares, that if men kept their blood cool and sweet, by a moderate and cooling diet, they would never be troubled with ulcers, or other breakings-out. Which coolness of the blood will be well attained to by drinking a large draught of water in the morning, which also will carry off the bilious and salt recrements by urine. And, if water is drank also after dinner, it will cool a hot stomach, and prevent the rising of those fermentations which cause wind and belching after meat. So that if persons who are liable to these disorders will leave off strong liquors and a hot diet, and drink water, they will procure better health to themselves than they had before.
