Native Americans started the tradition of using Sacred Sage to ward off evil spirits and negative energies, and white sage has been used in ceremonies to seek blessings of health and prosperity, banish spirits, and encourage protection. Sage Smudging is a ritual where the leaves of the plant are burned, and the smoke is directed into and onto areas that are in need of clearing and protection.
The idea is that as the leaves are burned, and you speak express your gratitude for its assistance, the spirit of the plant releases its energy of protection and clearing into the space or onto the object that needs clearing. As the smoke moves through the room or over a surface, the smoke attaches itself to any heavy, negative energy that is within the space, object or being. As the smoke clears, the spirit of the plant carries with it the negative energy that was once attached, back up to the Spiritual Light. This heavy energy then becomes released, so that it may regenerate into something positive. You can perform this smudging ritual on anything or anyone that needs a clearing.
