Precautions for use

Caution! Blue Tansy essential oil should be used with caution.

The only recommended route of application is dermal.

It should only be used by adults and children over the age of 6.

Its constituents make it an essential oil that is irritating to the skin and respiratory tract, similar to cortisone, and neurotoxic.

Its use must therefore be authorised by a doctor.

Be aware of its endocrine effects due to certain components.

Other precautions

Warning:

• Do not use this essential oil for long periods without the advice of a therapist.
• Babies, children and pregnant women can use this essential oil but in very diluted form and with the advice of a doctor.

Cutaneous use:

• Some components of blue tansy essential oil are irritating to the skin, so it should be diluted in vegetable oil (20% essential oil to 80% vegetable oil) before use.

Ingestion:  

• Exceptionally, blue tansy essential oil is used orally on prescription.

Endocrine effects:

• This endocrine effect may cause a shortening of the menstrual cycle (due to chamazulene acting on the pituitary-ovarian axis).
• This essential oil is forbidden in the case of hormone-dependent cancers (breast, prostate, uterus).

Allergenic components:

Blue tansy essential oil contains small amounts of biochemical allergenic components:

• Limonene (≤ 4%)
• Linalool (≤ 1%)
• Eugenol (≤ 0.5%)
• Citral (≤ 0.1%)

Note: It is best to test the essential oil before use (two drops on the crease of the elbow for at least 24 hours to check for a reaction).
