In the drinking cure, water from healing springs is drunk regularly over a longer period of time for therapeutic purposes. The drinking cure, also known as the well cure, was particularly widespread in the 18th century. The water from healing springs was used for internal cleansing of the body. Healing waters come from deep underground basins and either surface as springs or are tapped through wells. They originate from rainwater. They contain calcium, magnesium, hydrogen carbonate, fluoride and sulphate in varying compositions.
In addition to spas as part of a cure, a drinking cure with purchased water from healing springs can also be carried out at home.
