How Much Do You Know about Essential Oils?----One

1. Essential oils are highly concentrated, so they must be diluted with a carrier oil when used.

2. Essential oils are insoluble in water, so even after dilution with water, the concentration remains at 100%. Do not use directly on the skin.

3. Some essential oils are flammable, so store and use away from sources of fire.

4. Essential oils have a short shelf life and are easily oxidized, so be mindful of the storage environment.

5. Dark glass bottles are best for storing essential oils, as they protect them from sunlight and extend their shelf life.

6. Essential oils are best stored in a cool, dark location, but not in the refrigerator.

7. Essential oils are volatile, so it is best to store them in bottles with stoppers. Remember to tighten the caps after use.

8. The scent of essential oils can affect your mood and brain, so essential oils can be used directly by "smelling."

9. Essential oils can be absorbed through the skin, which can affect your skin and physical health.

10. Temperature can improve the absorption efficiency of essential oils, so other methods can be used to assist in their use, such as water vapor absorption.
