Sage, Salvia officinalis, a pungent spice that was once thought to instill domestic harmony, is rich in antioxidant, astringent, and antibacterial qualities. Sage has been proven to have astringent properties. Sage teas make an excellent skin toner.
Sage helps deeply cleanse the skin to prevent bacterial growth. It also has anti-inflammatory properties, which makes it ideal for treating wounds and calming acne and eczema flare-ups. Since sage helps regulate sebum production, it is good for both oily or dry skin and may help ease conditions such as, seborrhea, dandruff or acne.
Often used in natural hair care products, sage is a soothing hair tonic, and a natural treatment for scalp dryness, and sage tea may help darken graying hair.
