Our mugwort bundles are freshly bound in an undyed cotton cord from mugwort we harvest in our own garden. Mugwort is thought to have protective energy, and it can be used as an incense bundle (similar to a "smudging" bundle) or simply hung in the area where it is meant to have an effect.
Remember when using as incense that it is meant to smoulder, not burn. If flames occur, blow them out or smother them.
