The Five
Five oils, kept separate. Each does something different to a room.
Lavender
Lavandula angustifolia
Soft, powdery, faintly sweet. The one most people already know. For the last hour before bed.
Jasmine
Jasminum
Heavy, floral, close. A small amount fills a room and stays there. Use less than you think you need.
Eucalyptus
Eucalyptus globulus
Bright, cool, opens the room. Sharp enough to notice the moment it hits the air.
Tea Tree
Melaleuca alternifolia
Clean, sharp, medicinal-green. The most astringent of the five.
Lemongrass
Cymbopogon citratus
Citrus with a grassy edge underneath. Lighter than lemon, less sweet than orange.
Three to five drops in an ultrasonic diffuser. One to two drops diluted in a carrier oil for topical use. For external use only. Keep out of reach of children.
