What are Essential Oils?

Nature and Composition

Essential oils are powerful plant concentrates, obtained from different parts of plants, such as flowers, leaves, resin, or bark. Each essential oil is a unique complex of chemical compounds that gives the plant its particular aromatic characteristics. These volatile compounds are what give essential oils their distinctive aromas and therapeutic properties.

Extraction Methods

The most common method of extracting essential oils is steam distillation, although other methods like mechanical expression or supercritical CO2 extraction are also used for some oils. The quality of an essential oil can vary greatly depending on the extraction method, botanical source, and growing and harvesting conditions.

Varieties and Uses

There are hundreds of essential oils, each offering their own benefits and uses. For example, lavender oil is known for its relaxing properties, while lemon is appreciated for its refreshing and purifying effect.

How to Use Essential Oils Safely?

Responsible Use

The use of essential oils should be done with caution and knowledge. Although natural, they are extremely powerful and can be harmful if misused. Here are some essential guidelines:

  • Dilution: Essential oils should generally be diluted in a carrier oil (such as sweet almond or jojoba oil) before applying to the skin, to avoid irritant or allergic reactions.

  • Diffusion: When using a diffuser, it is important to follow the manufacturer's instructions and not diffuse continuously for long periods of time, especially in an enclosed space.

  • Ingestion: Consumption of essential oils is strongly discouraged without the advice of a qualified healthcare professional.

Specific Precautions

  • Pregnancy and Children: Certain essential oils are not recommended during pregnancy and for young children. It is crucial to consult reliable sources or a healthcare professional before use.

  • Medical Conditions: People with certain medical conditions should exercise caution. For example, mint-based essential oils can be problematic for people with heart conditions.

Test and Listen

Before using a new essential oil, it is advisable to do a skin test to detect possible allergic reactions. Additionally, listening to your body and recognizing signs of discomfort or adverse reactions is essential.

Purity is the most important criterion when purchasing essential oils. It is essential to look for 100% pure oils, without additives or diluents. The botanical source, including country of origin and growing conditions, also influences the quality of the oil.

Extraction Methods

The extraction method can affect the chemical composition and therapeutic properties of the oil. Oils obtained by steam distillation or cold expression are generally of better quality.

Certification and Labeling

Look for essential oils with quality and certification labels (like ECOCERT for organic oils). Labeling must include clear information on the plant of origin, the Latin name, and the part of the plant used.

Supplier Reliability

Choose reputable suppliers and trusted brands. It can be helpful to read customer reviews and look for recommendations from aromatherapists or medical professionals.
