Sage leaves refer to the foliage of the sage plant, scientifically known as Salvia officinalis. Sage is a perennial herb that belongs to the mint family, Lamiaceae. It is native to the Mediterranean region but is cultivated in many parts of the world for its culinary, medicinal, and aromatic properties.
 
The leaves of the sage plant are the most commonly used part. They are typically oblong in shape, with a soft, velvety texture and a gray-green color. Sage leaves have a strong, distinct aroma and a slightly bitter, earthy flavor.
 
Aromatic and Ritual Use: Sage leaves are also utilized in aromatherapy and spiritual practices. Bundles of dried sage leaves, commonly known as smudge sticks, are used in smudging rituals to cleanse and purify spaces, objects, or individuals energetically. The smoke from burning sage is believed to ward off negative energy, promote positivity, and create a sacred atmosphere.
