Houston attorneys Richard LaGarde and Mary LaGarde visited the Burgundy region of France last week and discovered that crawfish were used as a medication in the 15th century. They toured the Hospices de Beaune, a hospital for the poor built in 1443. One of the medicine jars in the hospital’s apothecary was labeled “Yeaux d’ ecrevisses” (Eyes of Crawfish). The ingredients were ground limestone and the interiors of crawfish. The medication was used to prevent diarrhea and hemorrhages. Cajuns have known for a long time that crawfish are good for you. It appears that their ancestors in France knew that too.
