How do I use sharp as a razor in a diffuser?

Add Rosemary 3 · Peppermint 3 · Basil 1 · Cedarwood 1 drops to 200–300 ml of water. In a room under 15 m², use 1–2 drops less; in a room over 25 m², add 1 more drop of the main oil.

What can I use instead of rosemary?

Swap rosemary for eucalyptus or tea tree — same herbal family. The blend will shift a little: eucalyptus is strong, cool and wide open.

When is the best time to use sharp as a razor?

Run it at your desk or study corner in cycles of 30 minutes on, 30 minutes off, so your nose does not tune the scent out.

How it unfolds

On opening. Rosemary (cool, green, herbal and invigorating); peppermint (cool, sharp and clean) rise first, clearest in the first 10–15 minutes.

As it settles. Basil (sweet and green with a hint of anise) forms the body of the scent and stays longest in the room.

What remains. Cedarwood (dry and warm, like a wooden chest and pencil shavings) sinks in and lingers after the diffuser is off.
