Infusion of Carduus.
Infuse an ounce of the dried leaves of carduus benedictus in a pint of common water, for six hours, without heat; then filter the liquor through paper.
This light infusion may be given, with great benefit, in weakness of the stomach, where the common bitters do not agree. It may be flavoured at pleasure with cinnamon, or other aromatic materials.
