Contraindications of essential oils


Aromas are handy to have on hand daily to take advantage of their natural, chemical-free benefits, but if used incorrectly, they may lead to unexpected encounters.

The precautions differ slightly according to symptoms, situation, use and age, and there are also contraindications.

It is not something to use based on complex special knowledge, but it is useful to know the basic precautions.


Essential oils can ignite

Essential oils can ignite. Each essential oil has a different heat resistance temperature, but it might catch fire.

The flash points of popular essential oils are as follows.


Juniper/33°C

Cypress/37°C

Citrus fruits such as lemon and orange/43-50°C

Rosemary/49°C

Teatree/57°C

Roman camomile/58°C

Neroli/59°C

Ylang-Ylang/65°C

Patchouli/65°C

Peppermint/67-70°C

Lavender/75°C

Geranium/77°C

Clary sage/77°C

Sandalwood/100°C


Those with a low flash point temperature are more volatile, and their fragrance is more easily released, while those with a high flash point temperature are less volatile, and their molecules are heavier.

Conversely, some essential oils solidify at temperatures below 10°C and should be wiped off each time they are used, even at room temperature.


The properties of essential oils are fat-soluble, volatile, flammable, liquid or semi-liquid, light yellow or transparent in colour, so knowing the flash point will help you to use them safely.
