Eye Scum

Pow-Wows, or Long Lost Friend, by John George Hoffman, [1820], at sacred-texts.com

TO REMOVE A SCUM OR SKIN FROM THE EYE.

Before sunrise on St. Bartholomew's Day, you must dig up four or five roots of the dandelion weed, taking good care to get the ends of the roots; then you must procure a rag and a thread that have never been in the water; the thread, which dare not have a single knot in it, is used in sewing up the roots into the rag, and the whole is then to be hung before the eye until the scum disappears. The tape by which it is fastened must never have been in the water.
