Remedies for Kidney Ailments in Physica by Hildegard von Bingen (1098-1179)

Abstract

Objectives: Hildegard von Bingen (Hildegardis Bingensis; Saint Hildegard), the Sibyl of the Rhine (AD 1098-1179), was a Benedictine abbess, musician, poet, writer, counselor, and healer. As an influential personality of the 12th century, she was advisor of kings, princes, and bishops. Her medical work is collected in 2 books (AD 1152-1163): Physica and Causae et Curae. We aimed to investigate the characteristics of the nephrology-oriented remedies in Physica and compare these with the respective remedies in De Materia Medica (AD 1st century) by Dioscorides Pedanios Anazarbeus.

Materials and methods: Physica is a collection of 9 volumes with an inventory of plants, trees, elements, stones, animals, and metals and describes the associated natural therapeutic properties. We studied all 293 plants (230 herbaceous plants, and 63 trees) in this treatise and recorded all nephrology-related remedies. In addition, we recorded the treatment indications of the same remedies in De Materia Medica. Nephrology-oriented material was defined as any item with nephrology-related pharmacological action (diuretic) or indication (eg, dysuria, nephritis, stones, sand, dropsy). Our findings are presented as simple descriptive statistics.

Results: Among all plants, there were 15 (5.1%) of nephrological interest (11 herbaceous plants and 4 trees). Only some of the natural ingredients mentioned in Physica were found with the same indication in the ancient text, De Materia Medica (9 of 15). The nephrological treatment indications described in Physica included dysuria, nephritic pain, and lithiasis in 87% and dropsy (edema) in 13.0%, which is comparable with 10% in De Materia Medica.

Conclusions: Physica provides a reliable account of medicine in the 12th century as it was practiced by the clergy for generations. It also incorporates Hildegard's personal observations and contemporary folk remedies. This fact is supported by the limited similarity of nephrological remedies in Hildegard's Physica with the respective remedies in De Materia Medica.
