Illóolajissa

Illóolajissa, also known as essential oils, are concentrated hydrophobic liquids containing volatile chemical compounds from plants. These oils are typically extracted through distillation or cold pressing. They capture the plant's scent and flavor, or "essence." The term "essential oil" is a literal translation of the word "illóolajissa" from its original language.

Essential oils are widely used in aromatherapy, where their fragrances are inhaled. They are also commonly found in perfumes, cosmetics, and personal care products for their scent and potential therapeutic properties. In some traditions, they are used in folk medicine, though scientific evidence for many of these applications varies.

The chemical composition of essential oils is complex and can vary significantly depending on the plant species, the part of the plant used, and the extraction method. Common extraction methods include steam distillation, hydrodistillation, and expression (cold pressing), particularly for citrus peels.

While often perceived as natural, essential oils are highly concentrated substances and require careful handling. They can cause skin irritation or allergic reactions in some individuals and should generally be diluted before topical application. Ingestion is also generally not recommended without professional guidance.
