Over the last few years, a centuries-old practice from several Indigenous cultures has turned into an interior design trend: sage bundles next to the houseplant, Palo Santo at the concept store, incense labeled “cleanses energy” or “clears bad vibes.”
Before you buy the next bundle, it’s worth taking an honest look: what’s actually happening scientifically — and what’s mostly good marketing?
What’s measurably happening
Smoke genuinely changes indoor air — that’s true regardless of any spiritual interpretation. Burning releases essential oils and compounds that vary by plant.
With white sage, some studies point to a mild antimicrobial effect of the smoke on certain airborne bacteria. Aromatic compounds like the terpenes in Palo Santo can also measurably affect the limbic system, similar to aromatherapy in general — scent is directly wired to brain regions tied to emotion and memory.
That explains why a ritual can genuinely feel calming: a specific scent, combined with a deliberate pause and a repeated action, is relaxing — not because “negative energy” is burning away, but because your nervous system responds to smell, ritual, and conscious pausing.
That’s real, but it’s a different thing from what’s often being sold.
Where the marketing takes over
“Cleanses the room of negative energy.” “Clears bad vibes.” These phrases are vague enough that they can never be disproven — which is exactly what makes them so easy to sell.
No one can check whether “negative energy” was present or is now gone. The feeling of effectiveness still shows up, because the ritual itself (scent + pause + intention) genuinely does something to your nervous system — just not what the label claims.
There’s also an issue that goes beyond effectiveness: white sage and Palo Santo come from Indigenous spiritual practices (among various North and South American cultures) that are often stripped entirely of their original cultural and spiritual context through commercial adoption.
White sage is also now considered overharvested in parts of its natural range.
Smudging vs. Aromatherapy: Where the Difference Lies
There’s an important distinction that often gets skipped in the smudging trend: burning isn’t the only way to use scent intentionally — and for many effects, it isn’t the best-researched one either.
Aromatherapy with essential oils (via diffuser, roll-on, or a few drops on a pillow) skips combustion smoke entirely, and individual scents are considerably better studied than burning smudge bundles.
A few scents with comparatively solid research on calming the nervous system:
- Lavender: The best-studied “calming” scent. Several studies show effects on anxiety levels, heart rate, and subjective relaxation, in some cases comparable to mild anti-anxiety measures.
- Bergamot: Some studies link it to lower stress markers and improved mood, often tested in combination with lavender.
- Vetiver: Described in aromatherapy as “grounding,” with early studies linking it to a calming effect on the nervous system, particularly for inner restlessness.
- Roman Chamomile: Traditionally, and in some studies, associated with mild anxiety-reducing and sleep-supporting effects.
- Cedarwood: Contains sesquiterpenes that can act on the limbic system; often described as having a sedative effect.
- Ylang-Ylang: Linked in some studies to lower blood pressure and heart rate — tends to relax rather than energize.
Worth keeping in perspective: effect sizes are generally moderate, the evidence is strongest for lavender, and still fairly preliminary for the others. Aromatherapy doesn’t replace medical treatment, but — similar to a mindful smudging ritual — it can genuinely affect your nervous system through scent, expectation, and a brief pause, just with better-dosed, smoke-free application.
What you can do instead
This doesn’t mean smudging is inherently pointless — but it’s worth looking a little more closely:
Choose alternatives without the appropriation issue
Dried herbs from your own garden, or European smudging plants like mugwort, lavender, or rosemary, offer similar aromatic effects without being borrowed from a closed spiritual practice.
Call the ritual what it is for you
If a scent-pause helps you unwind, that’s completely legitimate — you don’t need to frame it as energetic cleansing to get value from it.
Mind the ventilation
Any burning smoke adds particulate matter to your indoor air, regardless of the plant. Worth considering if you have sensitive airways or young kids at home.
Expect what the ritual can actually deliver
A few minutes of mindful pause with a pleasant scent can be supportive — but it doesn’t replace real nervous system regulation when the tension runs deeper than a single scent note can reach.
If you’re looking for real effect, not symbolism
This is exactly where the difference between a nice ritual and actual regulation lies. Our products don’t work with symbolism — they uses techniques with measurable effects on your nervous system, short enough for daily life but effective enough to make a real difference.
