An alkaline (antacid) mineral water of France, more agreeable because of its containing some free carbonic acid gas. It is recommended for dyspepsia with sour stomach; for gravel, and for gout; especially when the last named affects the stomach and digestion. Vichy lozenges are sold by apothecaries, being intended to imitate vichy water when dissolved. They are often found serviceable to persons subject to sourness of stomach after eating.
