There are several ways companies extract essential oils from actual plants. The most common method is steam distillation. The oils attach themselves to the steam, then the steam is cooled into water, which separates out the oils, since oil and water don't mix. Citrus peels and seeds are pressed to release essential oils, similar to how olive oil is made. Fragile and costly essential oils are extracted through two methods that don't require heat: carbon dioxide and solvent extraction. These techniques require chemicals, but some essential oils, such as jasmine, can only be produced this way. Solvent-extracted essential oils are labeled "absolute."
What is a carrier or base oil?
A carrier oil is a neutral vegetable oil so named because it "carries" the essential oil. Essential oils are strong and must be diluted in other substances before they're applied to the skin. Sweet almond, apricot kernel, and grape seed oils are popular choices for carrier or base oils since they have light scents that won't interfere with your chosen essential oils.
What is a floral water or hydrosol?
When essentials oils separate from water during steam distillation, the condensed steam retains some of the scent and beneficial compounds from the actual plant. This byproduct is known as a hydrosol or floral water and makes a great facial toner or freshener for skin and hair.
What is an infused oil?
To make infused oils, manufacturers steep leaves and flowers in a neutral base oil until this oil acquires some of the scent and beneficial compounds of the plant. Calendula oil is a great example of an infused oil. It has both the healing benefits of calendula and the healthful components of the particular base oil.
How can I use essential oils?
Many people like to use essential oils to fragrance bath and body products, creating scents that improve mood and concentration, relax the body and relieve tension. You can scent body oils and lotions with them, as well as add them to bath salts and bath oil to create an aromatherapy tub experience. You can also diffuse essential oil scents into a room to cover cooking scents and other unpleasant odors or create a particular mood.
Is there any time using essential oils might be unsafe?
Essential oils are relatively safe, but because they're so concentrated, there is potential for irritation. Always dilute essential oils before applying them to the skin! Since many of the citrus oils have the potential to make certain skins sensitive to sunlight, they should be avoided before sun exposure. Some essential oils can affect hormones, so women who are pregnant and nursing need to talk to a doctor or aromatherapist about which oils are safe for them.
