What are Essential Oils
Essential Oils are naturally occurring, volatile compounds that are found in the seeds, bark, roots, flowers, stems, and other plant parts. And what exactly is a volatile compound? I will give you a brief explanation, these compounds are small organic molecules that tend to change quickly from their solid or liquid state to a gas at room temperature. They are called volatile because they change state quickly.
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.
Missing and Using Essential Oils 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.
* 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.
