Frankincense: what the science shows, and what it doesn't.

Frankincense is the heart of the Grounding candle, and it's worth being precise about what the science here is — and isn't. The most-cited study is a 2008 paper showing that incensole acetate, a compound in frankincense, activates a specific brain ion channel (TRPV3) and produces anxiety- and depression-reducing effects.

The honest caveat, up front

That study was done in mice, not people, and it concerns an isolated compound, not the scent of a lit candle. It tells a plausible mechanistic story — there's a receptor in the brain that frankincense's chemistry can act on — but it is not evidence that burning a frankincense candle treats anxiety in humans. We're including it precisely because it's the kind of result that's easy to overclaim, and we'd rather show you the ceiling ourselves.

Why it's in the Grounding candle

We chose frankincense for its scent first: deep, resinous, and room-settling — the note that makes Grounding feel like a closed door. The mechanistic research is an interesting footnote to that choice, not the reason for it.
