For A Cough

Take a wine glass of the juice of the green hoarhound, or if that cannot be obtained, a strong decoction from the dry herb will answer; mix it in half a pint of new milk, sweetened either with sugar or honey; take this half an hour before breakfast. It has been known to cure obstinate coughs, and persons that have taken it for four weeks or more, have gained strength and flesh, and the pain in the breast was relieved. Flannel should be worn.
