sage

White Sage has been used since the dawn of time to perform fumigation and purification rituals.
Native Americans consider white sage to be a sacred plant. They use it during purification & protection rituals, and during religious ceremonies, deaths and births.
Tradition says that its smoke purifies the atmosphere and drives out negative waves, thus raising the vibratory rate of houses and their inhabitants. Fumigation, according to tradition, drives out evil spirits and offers us well-being and protection.
