- Never put pure essential oils in the nose, in the ears or on the ano-genital mucous membranes

The use of essential oils during pregnancy and for breastfeeding women requires the advice of a knowledgeable aromatherapist.


In case of hypersensitivity or allergic ground, test the essential oil before use:
- place 1 to 2 drops of the selected essential oil in the crease of the elbow,
- wait 10 minutes,
- note a possible skin reaction

Do not expose yourself to the sun after applying an essential oil containing furocoumarins (EO expressed by citrus zest: lemon, tangerine, sweet orange, etc.). These essential oils are photo-sensitizing and greatly increase the risk of sunburn and burns.

Essential oils that are phenolic or rich in aldehydes are dermocaustic (aggressive for the skin) and must be diluted in a vegetable oil in a proportion of 85% vegetable oil for 15% essential oil.

The use of essential oils internally requires the advice of a professional. In case of accidental ingestion: ingest vegetable oil and contact a poison control center.

Essential oils are not soluble in water. For an aromatic bath, use a suitable dispersant (labrafil, labrasol, disper) in an amount 4 times greater than the amount of essential oil. Do not exceed 10 drops of essential oil per 100 liters of water.
