Ingestion of Essential Oil

We do NOT recommend the ingestion of HYANG STUDIO essential oils as they are highly concentrated and can cause damage internally if administered without expertise. We strongly advise you to consult with your medical doctor or a knowledgeable health practitioner before using any brand of essential oils internally to ensure a safe and optimal program for your individual body.

When planning to introduce a new essential oil into your healthcare program, test one drop on a small patch of skin first (e.g., on the underside of the forearm). Sensitivity to particular essential oils is highly individual. If the skin feels hot or turns red, this indicates sensitivity, and this essential oil or blend should NOT be used in your healthcare program. Apply a vegetable oil (e.g., olive or almond) to the area, which will dilute the essential oil. Washing with water is less effective.


When applying topically

Apply only one new essential oil or blend at a time to the patch of skin to determine how your body responds. Wait 30 minutes before testing another new essential oil.

DO NOT attempt to self-diagnose or prescribe any natural substances for health conditions that require professional attention. Consult your healthcare professional about any serious disease, medical condition, or injury, or if you are pregnant, nursing, or planning to become pregnant. 

HYANG STUDIO understand that essential oils are not a substitute for professional medical care.

Safety Advice

Essential oils are highly concentrated, powerful liquids. Their potency must be respected, and they can be toxic if used incorrectly. The way you handle and use essential oils is very important.

Please read the following advice to help ensure that you use essential oils safely and effectively. Please note that this list does not constitute a complete safety reference. If you are unsure please contact us or a qualified local aromatherapist for more advice.


  • Certain essential oils are flammable liquids.

  • Keep out of the reach of children under age 16

  • If you have a medical condition and are taking any medication or undergoing any type of medical treatment you should check with your doctor and a qualified aromatherapist to ensure that it is safe to use aromatherapy in conjunction with your prescribed treatment.

  • Certain essential oils should be avoided during pregnancy

  • Always consult a qualified aromatherapist before using essential oils with babies and children.

  • Never take essential oils orally and avoid all contact with the mouth area and eyes.

  • Essential oils should never be applied undiluted to the skin as they can cause irritation ( there are only a couple of exceptions to this rule i.e. Lavender and Tea Tree). Follow all recipes and methods carefully and do not increase the amount of essential oil quoted.

  • Certain essential oils ( i.e. Cinnamon ) can cause skin irritation for people with sensitive skin. If you have sensitive skin we recommend performing a small patch test prior to using any new oil or product.

  • A few essential oils such as Bergamot and other citrus oils are photo toxic / photo sensitivity which means they can cause skin sensitization and skin discolouration in bright sunlight. These oils should be not be applied to the skin before direct exposure to sunlight.



Many essential oils are flammable, so never use or put your bottles of essential oil near a naked flame, fire, or any source of ignition.


Undiluted essential oils

Do not apply undiluted essential oils directly to the skin.

Never use undiluted oils on children under the age of 3. Their under-developed and delicate organs cannot excrete the oils or deal with their metabolites efficiently.



If you are pregnant you should seek the advice of a medical practitioner, mid-wife or aromatherapist before using any essential oils. Once the use of essential oils has been endorsed by the medical practitioner, midwife or aromatherapist then they should be used only after the first trimester, and at a 1% concentration only, being half the normal strength.

It is a good idea to seek the advice of your supplier or aromatherapist to ensure that the essential oils you are thinking of using are not contraindicated during pregnancy. There is a lot of misinformation about precisely which essential oils should not be used and some aromatherapy books produce a huge list of contraindicated oils that are completely out of proportion to the facts.

Much of this misinformation is based on the internal use of the plant in herbal preparations, and this is certainly not the same as the external use of a diluted essential oil in massage. Most essential oil experts argue that since many contraindicated essential oils are used as food additives they can hardly be considered dangerous.


Internal use

Never take essential oils internally, unless under the guidance of a qualified aromatherapist who has received the necessary training in this very specialized mode of administration. Most aromatherapists have not had this training, so be sure to check this out first.

You may read articles in magazines and books extolling the virtues of taking essential oils internally, but you should absolutely never attempt this without expert guidance.


Irritants and sensitizers

Some essential oils can irritate the skin if used in too high a concentration or for a long period of time. The essential oils below represent the most commonly known among this group.


  • Bay Leaf oil (Pimenta racemosa)

  • Cinnamon bark oil (Cinnamomum zeylanicum)

  • Clove oils (stem, leaf, bud) Syzygium aromaticum

  • Litsea Cubeba aka May Chang oil (Litsea cubeba)

  • Origanum oil (Origanum vulgar)

  • Tagette oil (Tagetes minuta)

  • Thyme white and red oil (Thymus vulgaris)

  • Use no more than 3 or 4 drops of citrus oils in the bath since some may irritate sensitive skin.



Photosensitivity, also known as photo irritation or phototoxicity, is a chemically induced skin irritation that can occur when you topically apply certain essential oils and expose your skin to UV light too soon. 


Some examples of the irritation you can experience are:

  • Redness

  • Burning

  • Itching

  • Blistering

  • Skin discolouration

  • Inflammation


Some essential oils are mildly photosensitizing and should be either avoided or used at a low level prior to sunbathing or using a sunbed. The main photosensitizing oils used in aromatherapy include:


  • Angelica root oil (Angelica archangelica)

  • Bergamot oil expressed (Citrus aurantium ssp. bergamia)

  • Bitter Orange oil (Citrus aurantium)

  • Cumin oil (Cuminum cyminum)

  • Lemon oil cold pressed (Citrus limonum)

  • Lime oil expressed (Citrus aurantifolia)

  • Grapefruit oil (Citrus paradisi)

  • Tagette oil (Tagetes minuta)


To reduce the effects of photosensitivity users should avoid the sun, tanning beds, or any UV light for 12 – 18 hours after you apply the oil to exposed skin.
