Firstly I want to say that I wrote this in response to watching some ghost hunters on a You Tube Channel dealing with a ‘negative energy’ inside a person’s home with sage and not only did they not treat the process with respect they also really did not deal with the situation in a proper way in general.
Burning sage to “clear negative energy” has become one of the most recognisable modern spiritual practices. It shows up in haunted houses, wellness spaces, witchcraft circles, and even real estate listings. But where did this belief come from — and does it actually do anything?
It is not proof of spirits being physically removed, but it’s also not meaningless superstition.
Let’s break it down.
Across cultures, smoke was believed to:
Carry prayers to the spirit world and act as a boundary between realms.It’s been used to purify people, objects, and spaces. It’s also been known to drive away illness, bad luck, or unwanted forces.
Different cultures used different plants:
White sage (Salvia apiana) — Indigenous peoples of North America
Juniper — Siberian, Mongolian, and some Slavic traditions
Mugwort — European folk magic
Frankincense and myrrh — Middle Eastern and Christian traditions
Palo santo — Indigenous
Smoke was seen as ‘liminal’, neither solid nor air ,perfect for dealing with things that were also believed to exist in the “in between.”
Sage earned its reputation for a few key reasons:
In Indigenous North American traditions, sage was used in cleansing rituals, illness prevention, and protection — not as decoration or ambience. It was part of a larger ceremonial system involving intention, prayer, and community.
Sage wasn’t burned casually. It was used for a specific purpose.
In pre-modern thinking:
Bad smells = decay, illness, corruption
Strong aromatic smoke = vitality, dominance, protection
If something unwanted was present, overpowering it with scent made intuitive sense.
Burning sage for example visibly changes the air, it alters smell, lighting, and atmosphere.
It marks a “before” and “after” moment.
That alone can create a powerful psychological shift.
Is There Any Scientific Proof?
Smoke does kill bacteria.A well-known study published in the Journal of Ethnopharmacology found that burning certain medicinal plants (including sage-like herbs) reduced airborne bacteria by up to 94%, with effects lasting hours.
So it doesn’t quite remove spirits but it does reduce microbes in enclosed spaces and in many cases it can aggravate spirits according to many well known reports of poltergeist like episodes.
To ancient people, illness and spirits were often the same thing. If sickness disappeared after ritual smoke, the conclusion was obvious: the bad thing left.The bad thing was often looked at as a demonic spirit rather than an illness.
Burning sage can:
Signal safety and closure
Reduce anxiety through repetition and familiarity
Create a sense of control in uncertain environments
When people feel calmer, spaces feel lighter. That experience gets interpreted spiritually.
Does Sage Remove Negative Spirits?
There is no scientific evidence that sage removes literal entities or spirits.
However:
There is evidence that smoke cleans air
There is evidence ritual changes human perception
There is historical back up for smoke as spiritual protection.
Belief fills the gap between experience and explanation.
For people who believe in spirits, sage becomes a tool. For people who don’t, it becomes a psychological reset.
Both experiences are valid — but they are not the same thing.
Today, sage is often used without understanding its original purpose or as a quick fix for emotional or spiritual discomfort.
Burning sage without intention, grounding, or follow-up doesn’t do much beyond changing the smell of a room.
In traditional systems, cleansing was never the whole solution — it was the beginning.
People continue to believe sage removes negative spirits because:
It has deep historical authority
It creates an immediate sensory shift
It offers a visible action against the unseen
It makes people feel safer in spaces that feel “off”and people see it on You Tube or see it mentioned by so many spiritual psychics and specialists.
Sage doesn’t chase spirits like an exterminator.
It marks a boundary.
It tells the mind and body: something is changing now, I am making my space safer.
Whether that change is spiritual, psychological, or symbolic depends entirely on the person holding the smoke their belief in the effectiveness of what they are doing.
