Cool brain, smooth run · Peppermint, Rosemary, Eucalyptus Radiata blend

A cool brain running as smoothly as a brand-new machine. Four drops of peppermint open with a refreshing chill, three drops of rosemary add sharp green notes, and two drops of eucalyptus radiata bring soft, airy coolness. Great for a home office on a sunny midday. If you use it into the evening, cut peppermint to two drops and add a drop of lavender.

How it unfolds

On opening. Peppermint (cool, sharp and clean); rosemary (cool, green, herbal and invigorating); eucalyptus radiata (gently cool, softer than classic eucalyptus) rise first, clearest in the first 10–15 minutes.

What remains. With no woody or resin base note, this blend fades fairly quickly — switch it on again after 1–2 hours to keep the room scented.
