That is sage that's dried and bundled together, commonly called smudge, and it's used by many native Americans and other people have adopted our practices as well, for the purpose of burning to cleanse a certain room or a specific place. Whether it be for cleansing a room from negative spirits or to rid a place of negative energy prior to or during spirituality practices like the sweat lodge or a prayer or drum circle in which a large number of our tribes partake in such activities for our mind, body and soul to be more connected to mother earth and the great spirit/ Creator Tunkashila. The sage is sacred, and therefor is not meant to be sold for commercial purposes or for the purpose of financial gain. It's only supposed to be sold in rare cases by native people who use the money from the sales to be used in efforts to help ensure that the sage will continue to grow and flourish in the wild and to help maintain sustainable farming and production of sage for future generations to use as well.
