From the 16th century onwards, people believing the theory of signs saw the resemblance of an ill lung with tuberculosis in the Jerusalem sage plant. Many 19th and early 20th-century people suffering from tuberculosis were treated with the lungwort plant, sometimes achieving success. At present, it still is a helpful plant for respiratory afflictions.
