Essential Oil Extraction Methods
There are various methods to extract essential oils from plants. The method of extraction depends on the type of plant material and desired chemical compounds to be extracted. Some extraction methods used today include steam distillation, solvent extraction and cold pressed extraction.
The active ingredients and the properties of an essential oil are related to the extraction process.
Here are some common essential oil extraction techniques:
Steam Distillation:
- Most common method to extract essential oils
- Plant material is exposed to steam, which carries the volatile oils
- The resulting mixture is cooled, and the oil separates from the water
Solvent Extraction:
- Used for delicate flowers like jasmine and rose
- Plant material is soaked in a solvent like hexane to extract the oils
- The solvent is then evaporated, leaving behind the essential oil
Cold Pressing:
- The plant material is crushed to extract the essential oils
- No heat is used in this method
Plant Extract vs Essential Oil
While both essential oils and plant extracts are derived from plants, they differ in their concentration and method of processing:
Plant Extracts: Diluted forms of essential oils mixed with a carrier oil or solvent. They are generally milder and safer for topical use.
Essential Oils: Highly concentrated, undiluted extracts of plant compounds. They are potent and should be used with care.
