Sage has been used in food and medicines since ancient times. Historical records show it was cultivated by the ancient Greeks and Romans, and widely used throughout the Middle Ages. Amongst other uses, it was prized as a diuretic and an aid to sleep. In 1597, John Gerard wrote that sage “…is singularly good for the head and brain, it quickeneth the senses and memory, strengtheneth the sinews, restoreth health to those that have the palsy, and taketh away shakey trembling of the members.” Modern research carried out by Northumbria University, among others, has found that sage has beneficial effects in people with Alzheimer’s disease. Sage tea is useful as an aid to digestion and eases the discomfort of heartburn. An infusion of sage leaves, when allowed to cool, can be used as a mouthwash or as a rinse for hair to help clear dandruff.
