What are Essential Oils?
Essential oils are compounds extracted from plants. The oils capture the plant's scent and flavor, also called its "essence." Unique aromatic compounds give each essential oil its characteristic essence. Essential oils are obtained through distillation (via steam and/or water) or mechanical methods, such as cold pressing. Once the aromatic chemicals have been extracted, they are combined with a carrier oil to create a product that's ready for use. The way the oils are made is important, as essential oils obtained through chemical processes are not considered true essential oils.
How Do Essential Oils Work?
Essential oils are most commonly used in the practice of aromatherapy. They are either inhaled through the nose or mouth, or rubbed on the skin. They can occasionally be ingested, although this approach isn't always safe and is NOT recommended. The chemicals in essential oils can interact with your body in a number of ways. When applied to your skin, some plant chemicals are absorbed. Inhaling the aromas from essential oils can stimulate areas of your limbic system, which is a part of your brain that plays a role in emotions, behaviors, sense of smell and long-term memory. The limbic system also plays a role in controlling some unconscious physiological functions, such as breathing, heart rate and blood pressure. Some people claim that essential oils can exert a physical effect on your body in this way.
Roll-On vs. Concentrated?
Pure concentrated oils are, in general, too strong to be applied directly to the skin and must be diluted or used in a diffuser. Our Roll-On oils have been diluted in a blend of Sweet Almond Oil and Jojoba Oil and are ready to be applied directly to your skin. Everyone may react differently to essential oils. Even when pre-diluted always follow the directions and apply a small amount at first to see if you develop a reaction. If a rash or irritation occurs stop using the oil.
