Feeling bothered and blue? This old-fashioned herbal remedy might brighten your day.

"The ordinary Basill is in a manner wholly spent to make sweet, or washing waters, and sometimes it is put into nosegays. The Physicall (medicinal) properties are, to procure a cheerefull and merry heart..."
—John Parkinson, Paradis in Sole, 1629

A modern version: add a few drops of basil oil to a scent diffuser.
