Lemongrass is grass, not citrus. Its citral aldehydes flatten under heat, so cold nebulizing diffusion keeps that bright green lift intact.

May Chang (Litsea cubeba) is 70 to 85 percent citral, the brightest natural lemon note in aromatherapy. A clean, single-oil lift to start the week.

Bergamot is the only common citrus rich in linalyl acetate, the same calming molecule found in lavender. A 3-drop Monday-morning ritual.

Petitgrain essential oil is roughly half linalyl acetate, the same soft ester behind lavender. One tree, three oils, and a slow one-oil Monday ritual.

Roman chamomile is built on up to 85% angelate esters, the softest chemistry in the apothecary. Try the 3-2-3 reset to start your Monday slow.
