White sage is a sacred herb used for hundreds of years by Native Americans. White sage is associated with purity and when burned via a smudging, it can help cleanse objects, people, and places to get rid of negative energy or even bad spirits.
How to use a sage smudge:
Open the doors or windows, then place the bundle in a ceramic dish, bowl, incense tray, or other non-flammable vessel. Light one end of the sage stick with a match or lighter, let it burn for a few seconds, then blow out the flame to release the smoke. Walk slowly around each room, wafting the smoke in all directions.
