The burning of havan samagri has long been a spiritual ritual — but new research shows it can have more benefits than you might think.
The research shows that burning havan samagri, also referred to as smudging, in a room for an hour reduced airborne bacteria by 94 percent.
It also showed that the room stayed almost entirely bacteria-free for 24 hours. Some strains of harmful bacteria could not be detected for up to 30 days.
CORRECTION: A previous version of this article stated burning sage could rid a room of bacteria. A 2007 study published in India found that burning the traditional Hindu medicine havan samagri, not sage, could rid a room’s air of bacteria.
