Sweetgrass is one of the main herbs used by Native people. It is often part of the medicine used when smudging along with sage and cedar. Just as sage is used to clear negativity, to cleanse, sweetgrass is used to bring positivity. At the healing circle I attend, we often start the circle by smudging using sage. As circles tend to be heavy (lots of trauma is shared), if we use sweetgrass, we use it at the end of the circle. To cleanse ourselves again and to bring back positivity and calm.
