Essential oils are concentrated plant extracts that retain the natural smell and flavor of their source. They are obtained through mechanical pressing or distillation, and each essential oil has a unique composition of chemicals that affects its smell, absorption, and effects on the body. Essential oils are most commonly used in aromatherapy, a form of alternative medicine that employs plant extracts to support health and well-being. They can also be used in and around the home, as a natural mosquito repellent, or industrially to make cosmetics.

Essential oils can be used in aromatherapy, a kind of complementary medicine that uses smell to improve your health or applied topically to the skin. Studies have shown that essential oils may help boost mood, improve job performance through reduced stress and increased attentiveness, improve sleep, and kill bacteria, funguses, and viruses. However, because essential oils are so strong, it is recommended to use only small amounts, typically just a few drops, and to dilute them with a carrier oil, such as coconut or jojoba oil, to avoid skin irritation.

It is important to note that essential oils are not meant to be swallowed, and some oils, like birch and wintergreen, should be avoided altogether, especially in young children and the elderly, as they may cause serious problems. When using essential oils, it is recommended to be mindful about why and how you’re using them, and not to use them routinely, as your body can get used to them, lowering their effectiveness.

In summary, essential oils are concentrated plant extracts that can be used in aromatherapy or applied topically to the skin. They have unique compositions of chemicals that affect their smell, absorption, and effects on the body. While they may offer some health benefits, it is important to use them in moderation and with caution, as they can be very strong and may cause adverse reactions if not used properly.
