The questions you ask yourself (and the straightforward answers)

Is it scientifically proven? No, it’s not “luck”; yes, it’s the pleasant subjective effect of a scent combined with a mini-ritualization (routine + breathing).
Does it remove “negative energies”? Or rather, it helps create an atmosphere that suits you, quite simply.
How many times a week? Once or twice is enough: a short, regular ritual is better than excessive fumigation.
Fresh or dried leaves? Dried: they are more fragrant and burn better; store them away from light, in an airtight jar.

Golden rule: safety and common sense

Always use a heat-resistant surface, keep a window ajar and keep any flammable objects away.

Always have a glass of water handy.

Favor smoke-free alternatives if air quality is an issue (small spaces, winter).

Bay leaves remain an aromatic plant: we use them for the pleasure of the senses and the “routine” effect, not for unrealistic promises.

Ultimately, bay leaves are a wonderful excuse to breathe, set an intention, and make your home a sweeter place—simply and safely.
