Native American smudge incense sticks are used for purifying the atmosphere, dispersing negativity, protection. Smudges put out a lot of soothing smoke. Very refreshing, relaxing, clearing --- like traveling through the clouds. To burn a smudge stick -just light the tip, blow it out and either wave in air or place in a glass or metal container (one that will not burn) with sand or salt placed therein to hold the smudge upright. To extinguish, invert smudge into the sand or salt to smother.
