This powerful plant has a long history of use, and research has shown why. Wild sage contains a variety of volatile oils, flavonoids (apigenin, diosmetin, and luteolin), and phenolic acids, including the valuable rosmarinic acid. Wild sage is a natural source of calcium, phosphorous, and magnesium. Historically, the Greeks and Romans prized it for its many healing properties. The Romans valued sage so highly that they held sacred ceremonies for gathering it.
