Eno's Fruit Salts
A remedy for indigestion (and hangovers) first sold to British sailors in 1874, the product was marketed world-wide by 1903. Eno’s Fruit Salts is a mixture of sodium bicarbonate, tartaric acid and citric acid. It is still marketed worldwide today as an aid to digestion. The British matron at Schutz in the 1920s, Miss Sturgiss, gave weekly doses of Eno’s Fruit Salts to all boarders in her care.
