1911 Encyclopædia Britannica/Soden
SODEN, a town and spa of Germany, in the Prussian province of Hesse-Nassau, pleasantly situated in the valley of the Sulzbach under the southern slope of the Taunus range, 10 m. from Frankfort-on-Main and 4 m. N. from Höchst by rail. Pop. (1905), 1917. The chief interest of the place centres in its brine springs which are largely impregnated with carbonic acid gas and oxide of iron, and are efficacious in chronic catarrh of the respiratory organs, in liver and stomach disorders and women's diseases. The waters are used both internally and externally, and are largely exported. Soden lozenges (Sodener Pastillen), condensed from the waters, are also in great repute. Soden has a large and well-appointed Kurhaus, an Evangelical and a Roman Catholic church, and a hospital for indigent patients.
