Rose oil is an essential oil commonly used in aromatherapy. Extracted from the petals of certain rose species, rose oil is thought to certain healing properties. Among the species most commonly used are Rosa damascena (damask rose), Rosa centifolia (cabbage rose), and Rosa alba (the white rose of York). These are the species known to have the strongest aroma and highest oil content.

Aromatherapy, also known as essential oil therapy, is a holistic practice that uses plant extracts to promote health and well-being. Rose oil is one of the most commonly used essential oils that some believe have anxiolytic (anxiety-reducing) and aphrodisiac properties.

When applied to the skin, rose oil may help relieve pain and inflammation while improving the overall quality of the skin. Rose oil is also one of the most widely used essential oils in the manufacture of perfumes and fragranced products.

Health Benefits

Practitioners of aromatherapy believe that inhaling essential oil or absorbing it through the skin transmits signals to the limbic system (a region of the brain responsible for emotions and memories). Doing so can induce physiological effects, including a reduction in blood pressure, heart rate, and respiration as well as an increase in "feel-good" hormones like serotonin and dopamine.

Others believe that it can act a natural antidepressant, relieve symptoms of arthritis and gout, or treat spasmodic disorders like asthma, irritable bowel syndrome (IBS), and gastroesophageal reflux disease (GERD). Most of these claims are poorly supported by research.

As popular as aromatherapy is, there are few quality studies investigating the benefits of rose oil in preventing or treating any health condition.

Here is some of what the current research says:

Stress

According to a 2011 study in Chemical Senses, rose oil is able to decrease levels of the stress hormone cortisol in the blood. Doing so not only alleviates the physiological symptoms of stress (including rapid heart rate, increased blood pressure, and sweating) but stimulates the so-called mesolimbic reward pathway in the brain.

This effect was seen in both human volunteers and lab mice exposed to the scent of Rosa alba essential oil.

A more subjective study conducted in 2009 reported that the topical application of rose oil delivered more intense feelings of relaxation than the application of a placebo oil. This translated to a reduction in the respiration rate, blood oxygen saturation, and systolic blood pressure during stressful situations.

Menopausal Symptoms

Aromatherapy practitioners have long asserted that rose oil can alleviate symptoms of menopause, including hot flashes, anxiety, night sweats, and low libido. Despite some positive findings, few studies to date have been able to establish a clear cause-and-effect to explain how these symptoms are relieved.

Might it be the relaxing effect of the rose oil scent, or are there chemicals passed through the skin during a rose oil massage? Or, perhaps it's massage alone that render benefits? Because the study designs are so inconsistent and varied, it's hard to tell.

A 2018 review of studies published in the Journal of Menopausal Medicine tried to untangle these issues. In evaluating three high-quality study, the investigators concluded that rose oil (as well as lavender, fennel, and geranium oil) was able to significantly improve sexual function in menopausal women but did nothing to alter estrogen levels associated with the more overt menopause symptoms.

Alzheimer's Disease

As far-fetched as the concept may seem, there are scientists who believe that rose oil may delay symptoms of Alzheimer's disease, a progressive neurodegenerative disorder characterized by the loss of memory and cognitive function.

A 2017 study published in the Journal of Agricultural Food Chemistry reported that paralyzed roundworms (Caenorhabditis elegans) experienced restored physical function after being exposed to diluted rose essential oil. By contrast, the worm exposed to components of rose oil (such as beta-citronellol and geraniol) remained paralyzed.

While these findings may seem incidental, rose oil appeared to activate the glutathione S-transferase 4 (GST-4) gene in the worms, reversing a type of nerve injury similarly seen in the brains of people with Alzheimer's.

Among its many functions, the GST-4 gene tempers the oxidative stress placed of brain cells. Any dysfunction of this gene increases the risk of Alzheimer's and other neurodegenerative diseases.

Further research is needed to identify which substance in rose oil triggered this effect. If such a substance can be isolated, it may open the door to the development of drugs able to slow or prevent the development of Alzheimer's disease.

Possible Side Effects

Rose essential oil is extremely potent and should not be applied directly to the skin. Doing so may cause burning, stinging, redness, irritation, and increased sun sensitivity. Rose oil should always be mixed with a neutral carrier oil (such as avocado oil or argan oil) before applying it to the skin.

Allergy to rose oil is less common than to other types of essential oil (such as lavender oil) but may occur. People allergic to roses are clearly at greatest risk.

To avoid skin injury, always test rose oil on a small patch of skin and wait 24 hours to see if rash or any other signs of irritation develop. While decreasing the proportion of rose oil may mitigate the reaction, never rechallenge yourself with rose oil if you've had a serious reaction in the past (such as whole-body itching, hives, or wheezing).

Similarly, never inhaled rose oil directly from the bottle or used it in a poorly ventilated room. The oil contains compounds knowing phenols that can irritate the respiratory tract, causing nasal or throat inflammation and coughing. Prolonged inhalation, particularly in young children, may cause pneumonitis (lung inflammation) or pneumonia.

Rose oil should never be taken internally. Doing so can cause nausea, confusion, shortness of breath, vomiting, diarrhea, seizures, and even coma.

Call 911 or Poison Control at (800) 222-1222 if you or someone you know has accidentally ingested rose essential oil. Do not induce vomiting unless medical personnel tells you to.

Dosage and Preparation

Rose essential oil is typically sold in dark amber or cobalt blue bottles with a dropper cap. The colored glass reduces damage caused by ultraviolet (UV) radiation from the sun.

If used topically, rose oil used should be diluted with a cold-pressed carrier oil (which are less acidic than heat-extracted oils). The proportion of rose oil to carrier oil can vary based on how sensitive your skin is and whether you've used rose oil before. As a general rule, always start with a lower concentration and increase gradually as tolerated.

Most people will find a 2% rose oil solution tolerable. Simply mix 12 drops of rose essential oil to one fluid ounce (30 milliliters) or a cold-pressed carrier oil, lotion, or vegetable butter.

Rose oil also can be inhaled by sprinkling a few drops onto a cloth or tissue or by using an aromatherapy diffuser or vaporizer. You can also add a few drops to bathwater for a restorative bath. A little goes a long way.

Essential oils should be stored in a cool, dry room away from direct sunlight and in their original, light-resistant bottles. You can also keep them stored in the refrigerator if you like.

While some people will tell you that essential oils last forever, you should discard any oil that has become cloudy, thickened in consistency, smells funny, or lost its scent. Always keep the lid screwed on tightly to prevent oxidation and evaporation.

What to Look For

Not all essential oils are created equal. Because these products are not strictly unregulated, you should only buy the highest quality oils. Lesser oils are not only a waste of your money, but they are often made with fragrances, preservatives, and vegetable oils that can cause allergy or skin irritation.

Here are some tips that can help you choose the best essential oils possible:

  • Check the provenance. Reputable producers will not only include the Latin name of the rose species (such as Rosa damascena) but the country of origin as well.
  • Check the credentials. Some producers are members of the National Association for Holistic Aromatherapy (NAHA). Because they are bound by ethical and quality standards, their products are likely to be trustworthy. With that said, you can be a high-quality producer and not be a NAHA member. The NAHA seal is only one of several criteria you should consider.
  • Test the oil. You can tell that an oil has been diluted by placing a single drop on a piece of paper towel. If a large oil circle develops around the central drop, you have most likely purchased a cheap, vegetable-oil based product.
  • Don't be misled by terminology. Many producers will use terms like "clinical grade" or "therapeutic grade," but no such universal grading system exists. These suppliers are not necessarily being misleading, but terms like these are arbitrary and should not direct your buying choice.
  • Don't look for bargains. Make no mistake; essential oils can be extremely costly ounce per ounce. If you find an essential oil at a bargain price, you are more likely being sold low-quality wares.
  • Avoid plastic bottles. Quality essential oils do not come in plastic. Ever.
