From my understanding Smudging is a method of cleansing a space or yourself from negative energies. To smudge it is said you must get some dry White sage and tie it into a bundle and light it up and blow it out much like incense. Then you use the smoke as the cleanser.
I have not been able to find White Sage sold around my area. I found some type of sage at the store but its not white sage. I was also wondering if it has to be sage or if it could be another herb like Lavender of something 🙂
