Essential Oil Safety

Pure essential oils are very strong and should only be used in the recommended dilution and application.  Some oils are toxic, some are skin irritants.  Many oils have contraindications to their use and may exacerbate existing health problems.    There are local and general contraindications to practice.  These must be identified during a preliminary consultation before any oils are used on a client. Care must also be taken when using Essential Oils at home. 

Main safety considerations

  • Oils should be stored correctly, out of the reach of children.
  • Some oils are flammable, keep away from flames and burners.
  • Oils should not be used until a consultation has taken place to identify all the general and local contraindication to practice
  • Oils should not be used unless the practitioner is familiar with the therapeutic properties and all the contraindications.
  • Oils should always be used at the recommended dilution.
  • Oils should never be taken internally.
  • If a consultation suggests skin sensitivity, test oils on a skin patch first.
Mixing and using safely
  • Wash hands before and after use.
  • Use oils in a well-ventilated area.
  • Mix blends away from the client.
  • Use within recommended dilution.
  • Use smaller quantities for babies, small children and the frail elderly.
  • Handle oils carefully to prevent contact with skin and cross-contamination.
  • Keep out of contact with the eyes.
  • Avoid prolonged or excessive exposure.
  • Take frequent breaks.
  • If prescribing oils for a client's home use, ensure that they understand the instructions for use.
  • Keep accurate records of treatment and blends.
  • Lavender and Tea tree are the only oils that can be applied directly on to the skin undiluted.  Always skin test first.
