Physica

Physica, also known as Liber Simplicus Medicina or Book of Simple Medicine, is a natural history and medical text by Hildegard of Bingen.

It catalogs the healing properties of plants, animals, stones, and metals.

Organized into nine books, each devoted to a different category of natural substances, it describes the nature and medicinal uses of each.

Hildegard often includes instructions on how to prepare and apply these substances.

Its significance lies in its contribution to medieval botany and medicine, and its impact on beer brewing due to its description of hops.
