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 often used in aromatherapy, a form of alternative medicine that employs plant extracts to support health and well-being. Some of the most popular essential oils include lavender, tea tree, frankincense, peppermint, eucalyptus, lemon, lemongrass, and orange.
It takes a tremendous amount of plant material to make essential oils, which can make some of them expensive. Essential oils can be added to vegetable oils, creams, or bath gels, or they can be smelled, rubbed on the skin, or put in a bath. Some research shows that they can be helpful, if used correctly. For example, simple smells such as lavender, chamomile, and rosewater may help keep you calm by sending chemical messages to parts of the brain that affect mood and emotion. However, it is important to always check the label and ask your doctor if you’re not sure if they’re OK for you to use.
It is worth noting that some of the health claims associated with essential oils are controversial. Previous studies have shown that lavender and tea tree oil may act as endocrine disrupting chemicals (EDCs), which have been associated with several health issues. EDCs are substances in the environment (air, soil, or water), food sources, personal care products, and manufactured products that interfere with the normal function of your body’s endocrine system. Therefore, it is important to use essential oils with caution and to consult with a healthcare professional before using them for medicinal purposes.
