Has anyone used rosemary oil for anxiety?

I used to believe "aromatherapy" was New Age hocus-pocus. I later found that certain fragrances (baking bread or cake, coffee, nag champa, patchouli) have a calming effect.
Maybe why they use incense in meditation.
I read that the olfactories are very close to the brain, so smells can trigger memories and moods. Baking smells take me back to Grandma's warm kitchen😊. Pine and peppermint smells make it Christmas🎄.
For Proust, a madeleine dipped in tea gave him a rush of chilhood memories.
In Search of Lost Time.
Hope you find yours.
