Essential oils are compounds extracted from plants. The oils capture the plant's scent and flavor, or "essence." Essential oils, which are obtained through mechanical pressing or distillation, are concentrated plant extracts that retain the natural smell and flavor of their source.

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.Because essential oils are so strong, it is recommends being mindful about why and how you’re using them.

Only small amounts, typically just a few drops, are used. It is a good idea not to use them routinely, as your body can get used to them, lowering their effectiveness.
