- They are considered “essential” because they carry the distinctive scent or essence of the plant from which they are derived.
Examples:
- Lavender oil from lavender flowers
- Tea Tree oil from the leaves of the Melaleuca alternifolia tree
- Lemon oil from lemon peels
2. Extraction Methods
Distillation:
- The most common method, involving the use of steam to release the volatile compounds from the plant material.
- Examples include lavender and eucalyptus oils.
Cold Pressing:
- Used primarily for citrus fruits like lemons and oranges.
- The peel is squeezed to release the oil.
Solvent Extraction:
- Used for delicate flowers like jasmine and rose.
- A solvent is used to extract the oil, which is then separated from the solvent through distillation or other methods.
