The following article was written by Michael Hills, and I am happy to share it here because I find it very interesting.
Please note: this is an older article and video, and when it was created, we used the term smudging in the general way many people did when referring to smoke cleansing. Today, we prefer to use the term smoke cleansing for general spiritual cleansing practices, while respecting that smudging is also connected to specific Indigenous traditions.
Using white sage smudge sticks is controversial. But how can you get the benefits of burning sage without using white sage? Using smoke for various reasons, like calling the spirits, and breaking up and cleansing your space of negative energies has been around for centuries. This is practiced almost everywhere on our planet by almost every race, creed, and religion.
The use of herbal smoke, and incense, is also used for medicinal purposes. It clears the air of unwanted impurities, with a health benefit attached to it.
