Cleanse and revitalise your space as you gently smudge with white sage.  White sage (Salvia apiana) is rich in compounds that help to activate receptors in the brain that are responsible for elevating mood levels, relieving stress, aiding sleep and sometimes helping with pain.  Smudging is a ritual practice throughout the world, bringing many benefits.
Ignite the leaves, or just use one leaf, to allow the cleansing smoke to waft around your area.
Be sure the embers are out once you have completed your ritual.
