Essential oils are liquid extracts of many potentially beneficial plants. But they are concentrated and can be dangerous if used incorrectly.
While a few test-tube studies show that ingesting some oils can treat certain ailments, this isn’t yet proven for most people. Plus, most “food grade” oils aren’t regulated by the FDA and may contain contaminants.
Antioxidants
Antioxidants are molecules that counteract unstable free radicals. They are found in foods and act as natural “off switches” for free radicals, neutralizing them before they can damage DNA or other cells.
Essential oils are made by steaming or pressing various parts of a plant, including the flowers, bark, leaves and fruit. They contain complex mixtures of volatile compounds that can create scent, but they also have therapeutic properties.
A recent study investigated the antioxidant potential of five essential oils (cinnamon, thyme, clove, lavender and peppermint) on fish oil emulsion and human red blood cell systems. The results showed that phenol-rich essential oils (cinnamon, hymeneal and thyme) had the highest antioxidant activity.
Antimicrobial
Essential oils (EOs) are complex mixtures of volatile components synthesized by plants. They consist of 20-60 chemical constituents at quite different concentrations. Most of the antimicrobial activity in EOs originates from oxygenated terpenoids (e.g., alcohols and phenolic terpenes), although hydrocarbons may also exhibit low activities. Interactions between EO components typically result in synergistic effects, but antagonistic and additive interactions have also been reported.
Although the FDA does not regulate EOs, a few studies have shown that they can improve health. It’s important to talk with your healthcare professional before trying them.
Antidepressant
When inhaled, the scent molecules of essential oils travel from your olfactory nerves to your brain. They stimulate your reward centers and may lift your mood. They can also decrease feelings of anxiety, stress and depression.
Studies have shown that some of the compounds isolated from these oils display antidepressant-like actions. For example, b-pinene and carvacrol both increase monoamines in the brain and act through mechanisms similar to classical antidepressants. Other essential oils that have antidepressant properties include bergamot, lavender and ylang-ylang oil. The most potent of these oils, however, is linalool and linalyl acetate from the lavender oil (Lavandula angustifolia Mill.)
Analgesic
Essential oils may relieve neuropathic pain caused by nerve damage. This type of pain can include tingling and numbness in the hands and feet.
Inhaling aromas from essential oils can stimulate parts of the limbic system, which plays a role in emotions and behaviors, and memory formation. Essential oils can also help reduce back pain by calming the muscles and reducing stress that can accompany it.
Essential oils are highly concentrated and should be diluted properly before inhalation, particularly by those with respiratory chronic diseases like asthma and COPD. Before using, consult with your healthcare professional to provide advice based on your unique health needs and conditions.
Antispasmodic
Essential oils can be inhaled directly from the bottle or mixed with a carrier oil and used to massage tense muscles. They can also be added to hot or cold compresses.
Inhaled essential oils may irritate the respiratory tract, so individuals with asthma or chronic obstructive pulmonary disease (COPD) should proceed with caution. They can also interfere with certain medications. Individuals should consult a healthcare professional for personalized advice.
Studies have shown that several chemical components of essential oils can produce antispasmodic effects through multiple molecular mechanisms: inhibition of voltage-dependent calcium channels, modulation of potassium channels, antagonism of cholinergic receptors and intracellular increase in cAMP and cGMP levels leading to smooth muscle relaxation.
Diuretic
Although essential oils are not regulated by the FDA, research is ongoing on their potential therapeutic uses (1). These natural chemicals may be useful in improving your health and wellness, as well as helping you to reduce the number of toxic products in your home and on your skin.
Essential oils are distilled from plants and used in perfumes, cosmetics, soaps and air fresheners. You can also add them to a bath or rub them on your skin. Most oils should be diluted with a carrier oil (like coconut or jojoba) before use to avoid irritation.
Inflammatory
The use of essential oils to promote healing is an ancient tradition. They are volatile and highly concentrated liquid aroma compounds from plants. They can be distilled or cold pressed. They have a characteristic odor and are generally colorless or slightly colored.
Many people claim that essential oil use improves specific health conditions, but scientific evidence is limited and more research is needed. Always prioritize safety and consult your healthcare professional for personalized advice based on your unique needs and risk factors. It is important to dilute essential oils before applying them to the skin.
