    Safe Use of Essential Oils

    August 6, 2025

    Using essential Oils  

    There are many ways to incorporate essential oils safely into everyday life, but the following are the most common. Note the amount of essential oil recommended would normally be from one oil or the sum of up to three different oils.  

    • Inhalation: Using an essential oil diffuser (either candle or electric) to disperse the oil into the air (Up to 1.5% i.e. 18 drops per 50ml of water) or placing a few drops on a tissue (up to 4 drops) and inhaling the fragrance.  Clay or wood diffuser discs can also be used.
    • Topical Application: Diluted in a carrier oil, lotion or cream and applying to the skin as a massage or a beauty treatment. (up to 1.5% concentration i.e. up to 6 drops in a tablespoonful (15ml)
    • Shower gel: (Up to 1.5% i.e. up to 6 drops in a tablespoon of fragrance free gel or salt)
    • Bath gel: This depends on the amount of water so approximately up to 10 drops ideally diluted in a tablespoonful of neutral bath oil, dairy or plant milk or vodka
    • Salt: Depending on the amount of water, up to 10 drops dispersed into a tablespoon of neutral bath gel or vodka and then mixed with a cup of sea, table or Epsom salt. 
    • Roll-Ons:  Diluted essential oils applied to the pulse points from a roller bottle. 1% i.e. up to 6 drops in 25ml of carrier oil
    • Room sprays: Essential oils dispersed into water (with a specialist dispersant or alcohol e.g. vodka) up to 2% i.e. 25 drops per 50ml
    • Pillow sprays: Essential oils dispersed into water (with a specialist dispersant or alcohol e.g. vodka) up to 1.5% i.e. 17 drops in 50ml 

    Important note: Some essential stimulating oils have a particularly strong aroma so the dilutions would be lower to avoid an overwhelming fragrance.

    Can I use essential oils on my skin directly? 

    Essential oils, with the exception of lavender and tea tree, must always be diluted with a carrier oil, also known as a base oil, before applying to the skin. Common base oils include almond, grapeseed, jojoba, and coconut, while more exotic options include rosehip, argan, avocado, and hemp seed. 

    Essential Oils and Children 

    Most essential oils are safe for use with children over 2 years; however, they are generally diluted more and should always be spot tested first. The International Federation of Aromatherapists who are registered with the UK Professional Standards Authority publish these guidelines  

    Essential oils and medication 

    Essential oils that are properly diluted and used according to the supplier's directions are unlikely to interfere with mainstream medications bought over the counter for everyday health and wellness conditions. However, if you are pregnant or have a medical condition which is being treated with prescribed medication, it is advisable to consult a healthcare provider.   

    Precautions regarding the use of essential oils? 

    1. Essential oils are highly concentrated and should be diluted with a carrier oil before applying to the skin.
    2. Conduct a patch test before using a new essential oil, especially if you have sensitive skin.
    3. If you are pregnant or breastfeeding, consult with a healthcare provider before use.
    4. If you have a medical condition, consult a healthcare professional before using essential oils.
    5. Consult a healthcare provider if you are taking prescribed medication .
    6. Avoid contact with eyes.
    7. Do not take internally.
    8. Avoid mucous membranes/sensitive areas of the body
    9. Keep out of direct sunlight after treatment with citrus oils to avoid the risk of skin photosensitivity
    10. Keep out of reach of children and pets
    11. Store in a sealed dark bottle (glass or aluminium) and away from  extreme heat
    12. Use high-quality, pure essential oils from reputable sources such as those registered with the ATC to avoid additives or contaminants that could be harmful. 

    Essential oils and  pets 

    Many essential oils are safe to use around pets, and they are particularly popular for dogs. However, they should be avoided on or near cats.

    Essential oil safety notes for pets is published by the National Association for Holistic Aromatherapy 

    The risk of allergies 

    Allergic reactions to essential oils from reputable suppliers, such as ATC members, used according to their detailed instructions, are rare. However, if you experience an allergic reaction to an essential oil, the first step is to stop using it immediately. Rinse the affected area with plenty of water to remove any remaining oil. If the reaction is mild, over-the-counter antihistamines may help relieve symptoms. However, if you are unsure or if the reaction is severe, seek medical attention right away by calling emergency services or going to the nearest Accident and Emergency unit. Avoid using that essential oil in the future and report the issue to the supplier.
