Herbal books

As of the Middle Ages, physicians and healers have been reporting on medicinal use of hops. First references originate from Arab physicians in the 11th century, pointing to the effectiveness of hops in treating inflammations and for relaxation.

A multiplicity of properties ascribed to hops was described in the splendid herbal books from the 14th to the 17th century: as a diuretic, for purification of liver and blood, against fever or spleen complaints. The digestion-promoting properties of hops are mentioned in practically all herbal books. Use of hops in gynaecology was of particular interest.
