What are Essential Oils?

Essential oils are natural products extracted from a single plant species. They can often be found in the stems, leaves, flowers, fruits or even roots of certain plants. Essential oils are also known as ethereal oils, volatile oils or aetherolea.

According to Wikipedia, “An essential oil is ‘essential’ in the sense that it contains the ‘essence of’ the plant’s fragrance—the characteristic fragrance of the plant from which it is derived.”

Essential oils are most commonly used for aromatherapy, a holistic healing treatment that uses essential oils to promote health and well-being. Aromatherapy is often used to induce relaxation, but there is no scientific proof that essential oils can effectively treat any conditions.

Before using essential oils you should always consult a health physician—improper use can lead to allergic reactions and skin irritation. Essential oils should also be kept away from children and pets—who are particularly susceptible to the toxic effects of improper use.

Where Did Essential Oils Originate?

Essential oils have been used throughout history be many different cultures. It is believed that the earliest pioneer of essential oils was Ibn al-Baitar, a physician, chemist and pharmacist from Al-Andalus in the 12th Century.

In the last few decades interest in essential oils has been reinvigorated with the popularity of aromatherapy and holistic approaches to medicine.

How are Essential Oils Made?

  • Carbon Dioxide: One of the newest ways to extract essential oils from plants is by using carbon dioxide. This method is generally more expensive, but leaves you with an essential oil that has a scent more similar to the original plant.
  • Expression: Many times essential oils are produced by pressing them from the leaves, seeds, stems or roots of freshly picked plants.
  • Distillation: Steam distillation is the most common approach to extracting essential oils from plants. Plants are hung over boiling water and the steam pulls the oils out of the plant.
  • Enfleurage: This process is one of the most expensive, and rarely used to extract oils. It involves placing the plant on top of animal fat, lard or vegetable fats—the fat then absorbs the essential oils from the plant. The fat is then separated from the oil using solvents.
  • Solvents: This method is often frowned upon because it involves chemical solvents. The plant is dissolved in a solvent (usually benzene or hexane) and then the solvent is evaporated–leaving behind the essential oil.
