Scrofula and Magic

Scrofula, characterized by swellings on the neck, is caused when someone inhales air contaminated with mycobacterium. The bacteria infect the lymph nodes in the neck. In the Middle Ages it was called "The King's Evil" because of the belief that the Royal Touch could cure it. The word scrofula itself is a diminutive of the Latin scrōfa, "breeding sow," presumably because pigs were subject to the disease.

Treatment did not have to rely on the Royal Touch. Figwort was recommended because of the "doctrine of signatures."

The doctrine of signatures dates from antiquity; Galen and Dioscorides, who were sources of medical knowledge used for centuries afterward, describe the disease. It claims that herbs resembling parts of the body can be used to treat ailments of that body part. Figwort, when dug up, showed tubercles that resembled the swellings of the lymph nodes. Therefore, figwort was used to treat swellings such as scrofula.

Paracelsus (mentioned here) in the 1400s explained this thinking as "Nature marks each growth ... according to its curative benefit." A 17th century botanist, William Coles, justified the doctrine of signatures theologically, believing that God made 'Herbes for the use of men, and hath given them particular Signatures, whereby a man may read ... the use of them."

But back to figwort. When the urge came to carefully catalogue the natural world with scientific names, figwort became scrofularia nodosa because of its previous reputation regarding scrofula.

The Royal Touch was more than just a touch and for more than just scrofula. We'll look at some other diseases tomorrow.
