• 2.5 ml or 90 drops (or half the blend) of white pine essential oil (Pinus strobus)
• 1.25 ml or 40 drops (or a quarter of the blend) of black spruce essential oil (Picea mariana)
• 1.25 ml or 50 drops (or a quarter of the blend) of cineole rosemary essential oil (Rosmarinus officinalis cineoliferum)
• empty essential oil bottle, or other small container

Precautions:

• This diffusing blend isn't suitable for children under 6.
• Cineole rosemary essential oil: some people with asthma may be sensitive to essential oils containing cineole. You can simply ventilate the room in case of coughing or other symptoms.

Pour the three essential oils into an empty bottle, then mix.

Give yourself some leeway

No need to measure the essential oils precisely; you can go by eye, by feel! You can also change the amounts of essential oils to highlight the scents you prefer and that speak to you.

Diffuse 5 to 15 drops, according to your essential oil diffuser's instructions.
