Are Essential Oils Harmful or Helpful?
We see them everywhere. From the miniature glass bottles composed of a singular essence, to skincare products containing a variety of plant-derived oils, to home cleaning products with the customary citrus aroma. And you likely know someone, or yourself, experiment with them as homeopathic remedies. But what exactly are essential oils? After all, they have been used for millennia to cure everything from stress and pain to ailments of every variety. Are they truly advantageous or merely a pleasurable but ineffectual practice?
Essential oils are compounds extracted from plants (flowers, fruit, leaves or seeds) obtained through distillation or mechanical methods such as cold pressing. The oils capture the plant’s distinctive scent or essence and are highly concentrated. Once extracted, they are combined with a carrier oil for personal use. They can be inhaled via a diffuser, rubbed on the body as a lotion, applied to pulse points, or as a bath or massage oil. They are also frequently utilized in candles and scent sticks. In rare cases, they are taken as an ingestible, though this is not recommended as there is no FDA regulation and the side effects can be toxic.
Once the selected aroma is inhaled, it stimulates areas of the limbic system. This is the part of the brain that controls emotions, mood, olfactory sensations, and long-term memory. It also controls some physiological functions such as heart rate and blood pressure. This connection to memory, emotions, and equilibrium can help explain the positive effect of essential oils on mood and the releasing of stress.
Real Health Benefits
A pleasant fragrance is all well and good, but do essential oils have any measurable health benefits? While most studies are inconclusive, some hospital and clinics have been using aromatherapy as a complimentary therapy (CAM) to patients undergoing medical treatment or when in recovery. Staff and patients report a more positive experience and outcome with aromatherapy accompanying their primary treatment plan including;
- Relief from anxiety and depression.
- Improved quality of life, particularly for people with chronic health conditions.
- Needle sticks and are less painful, such as for patients receiving dialysis or chemotherapy.
- Improved sleep during hospitalization.
- Enhances the quality of life for those with dementia
- Reduction of pain for people with kidney stones
- Ease pain for women in labor and decrease the need for pain medication
While these may seem to be merely “feel good” tonics to serious ailments, people of all conditions, especially those who experience chronic pain, benefit from alternative methods of easing discomfort and subsequent depression. The ensuing positive affect can lead to a more rapid recovery and positive general outlook.
