I work at a wonderful metaphysical book and gifts store, Body Mind & Soul in Houston, TX. And one of our biggest selling categories, and most frequently asked about, is our smudging department. Smudging is a space-clearing practice involving the smoke of sacred plants. Often cited as a Native American practice, smudging is not limited to any one indigenous culture, but something we see utilized in one way or form across many cultures. However, the white and desert sage bundles we most commonly associate with smudging are indeed native to North America.
