Cold Pressed- Aromatherapy Terms
In aromatherapy the term “cold pressed” refers to the extraction of an essential oil or carrier oil by crushing or squeezing. It is also sometimes referred to as cold expression.
The essential oils of citrus fruits are the oils most often extracted by this method. The peels of the fruit are run through a steel press to puncture the oil-containing cells in the peels.
Then they are put into a centrifuge where the oil is collected by spinning the mash at very high speeds to collect the oils that were released during the crushing process.
This is also how most carrier oils that are extracted from nuts and seeds are extracted. Sweet almonds, grape seeds, apricot pits and coconut meat all go through this process to extract the carrier oils we use in aromatherapy massage.

Extracting the oils from nuts and other fruits used in carrier oils and for cooking can be changed if they are heat extracted. So nuts such as sweet almonds, sesame seeds, sunflower seeds,
