Essential oils can cause allergic reactions. Therefore, if you are prone to allergies before using a new essential oil, it is better to test for individual sensitivity, especially for children.

Allergic reactions to an essential oil or a mixture of oils can occur in the form of:

  • respiratory failure, shortness of breath, suffocation, shortness of breath
  • increased heart rate, arrhythmia
  • headache, dizziness, tinnitus
  • allergic rash, redness, irritation and itching of the skin

There are a number of tests that can help you determine if you are allergic to any essential oil. The three main tests for allergic reactions include:

  • olfactory test
  • skin test
  • tolerance test for internal use
  1. Olfactory test.
    Mix 1 drop of essential oil 5 drops of any base oil. Put the resulting mixture on a piece of paper or a cotton pad. Bring the paper soaked with oil to the nose at a distance of 10-15 cm and take a few deep breaths. If after inhalation of the essential oil there is no cough, bronchospasm, shortness of breath, then this oil can be used for inhalation.
  2. Skin test.
    A skin test is carried out as follows: 1 drop of essential oil must be mixed with 5 drops of any vegetable oil and rub a small amount of this mixture behind the ear, on the elbow bend from the inside, on the wrist or in the sternum. If after 12 hours there are no signs of irritation, then this essential oil can be used for baths, massages, compresses.
  3. A tolerance test for internal use.
    Some essential oils in aromatherapy are used for internal use. If you have never before used any kind of oil inside, you should also test for allergies. Mix 1 drop of essential oil 1 tablespoon of vegetable oil. Then dissolve 1 drop of the mixture in 1 teaspoon of jam and consume inside 3 times a day. The next day, double the dose. If you did not feel an attack of a headache, weakness, a skin reaction did not occur, then this essential oil is suitable for you.

Such tests can be carried out with a separate essential oil, or mixtures of them.
