Aromatherapy is a therapeutic method that uses plants, particularly the essential oil of plants, other scented oils, and ointments to promote health benefits. The use of these plant-based materials, especially oil, originates back to the ancient people of Egypt, India, and China approximately around 1800 B.C. These ancient civilizations used aromatic oils to embalm the dead and promote healing in the living by massaging people with specially chosen oils depending on the ailment that needed treatment (Part Two: The History and Use of Aromatherapy). Throughout time and across the globe, aromatherapy has been used to promote countless positive effects in both the living and the dead. For the dead, aromatherapy is used to not only embalm the body and preserve organs, but also to encourage a healthy and fruitful afterlife. Some of the things that aromatherapy promotes in the living include cleansing of the soul, better digestion and circulation, the reduction of depression and anxiety, a strengthened immune system, a sharper mind and senses, and the elimination of toxins in the body (Barrett). One claim of aromatherapy even goes as far as saying that it can reduce travel-induced excitement in dogs (Wells).

Aromatherapy works by having a patient inhale or ingest the “essential oil” of plants or by having these oils massaged into his or her skin. This essential oil refers to the scented parts of a plant that make up the “essence”, “soul”, or “spirit” of the plant, and it is obtained by extracting it from particular plants (Barrett). Aromatherapy as a practice has been popular for centuries in all parts of the world, and it is still believed in and practiced today. In fact, countless businesses exist for the sake of promoting this practice. One major business is Aroma Vera, and they thrive on selling products that facilitate aromatherapy including essential oil diffusers, shampoo, lotions, candles, and so much more (Aroma Vera). The belief in aromatherapy is important because this practice has been commonly used in medicinal settings with the intent of curing diseases. Aromatherapy is an extraordinary belief because it is thought of as a miraculous practice and promises the impossible people. Aside from the claimed benefits of aromatherapy mentioned earlier, some of the more impossible and wilder claims that proponents of this practice have made include the fact that essential oils are “electronegative and electropositive” and therefore have “yin and yang qualities”, essential oils are able to pass through a person’s blood-brain-barrier, and that this practice changes your blood from red to blue, which creates many health benefits in the body (Buchbauer).

Some compelling evidence for belief in this practice is that there is success found in certain situations. Additionally, aromatherapy has been a practice that has been around for centuries. Therefore, some people may have adopted the mindset that since it has been around for so many years that it must be effective. On the other hand, even though aromatherapy has the outward appearance of science, there seems to be little to none peer-reviewed, replicated scientific research done on the effectiveness of the impossible claims that firm aromatherapy believers have made. For example, one study from the journal of Evidence-Based Complementary and Alternative Medicine finds that aromatherapy has the potential to relieve depressive symptoms, yet does not show actual results themselves (Sánchez-Vidaña). Additionally, some of the claims of aromatherapy, including the fact that it can cleanse your soul, are un-falsifiable.

The main cognitive contribution to this belief system is the placebo effect. Some people really do experience positive effects and have even been “healed” of certain diseases by using this practice. However, the reason for why this may be is that the fragrances, massages, and other methods of the aromatherapy practice make patients more comfortable and relaxed. Additionally, if people are told that the treatment they are receiving will work, they are likely to believe it and fall victim to confirmation bias of whether or not they are experiencing symptoms of their disease anymore. Furthermore, with a lowered stress level about the healing process, confidence in the authority figure that is administering this therapy, and a comfortable environment, the body’s immune system is able to heal itself more quickly and without stress interfering with the process. Therefore, people really might be experiencing positive benefits from aromatherapy, however the reason for their healing is not the therapy itself, but the placebo effect experienced fostered by the relaxing environment this practice creates for people.

Since aromatherapy has been around for centuries, it has become ingrained in certain societies’ structures and medicinal practices. Aromatherapy believers can come from all communities across all walks of life, however those with the most devout belief in aromatherapy are typically from communities that place a large emphasis on “holistic” and “alternative” medicine. These people might also really value and feel connected to Earth and nature. One large reason that these people have such a firm belief in and positive view of aromatherapy is because they think that natural drugs are the only ones in which people can have full confidence that there will be no side effects to be afraid of (Buchbauer). Some social influences that help them sustain their beliefs are the testimonies that people provide about their positive experiences with this practice, the immense industry that has built itself around this practice, and the fact that this practice is an enjoyable experience that can be shared with others.

In conclusion, even though aromatherapy does create a comfortable and relaxing environment for people, it has not been proven to achieve all of the other impossible claims about its positive effects. The placebo effect and confirmation bias are the two biggest contributing cognitive factors that lead to the continued belief in aromatherapy. These two psychological explanations have allowed people to justify the positive effects found when practicing aromatherapy.

  1. I liked reading this post because I enjoy using aromatherapy myself and found reading about the history and cognitive aspects of this belief. I definitely agree with you that the placebo effect plays a role and I am not surprised that the effects of aromatherapy are not scientifically based. I think if placebo effect plays a role and if there is no harm done, then aromatherapy is not dangerous to people (other than losing money and resources). Lastly, I liked reading about the history of this belief and it was cool to read it has been around for centuries.

  2. My dad owned a candle store in the Short North for 10 years, called Paul Robinett Aromatherapy!!! This is so funny to me, becasue I never considered it to be an extraordinary belief. It was always so innate for me that certain smells were connected with certain feelings. However, the extent to which it was with my dads candles was never extraordinary claims, it was more trendy than anything I think. Reading about the roots of aromatherapy and peoples beliefs in extraordinary healing powers was new and very interesting. What is one scent-feeling pair that you feel has some salience for you? For me, Eucalyptus and serenity will forever go hand in hand!

  3. My grandmother is a huge believer in aromatherapy. She has her own oil diffuser and countless amounts of essential oils. She even has a bracelet that absorbs oils and emits that scent all day. She got me into using essential oils as well! Although I don’t believe the oils have supernatural healing powers, I mostly diffuse oils to make my room smell good, like lavender or eucalyptus, and relax after a long day. It’s interesting that there’s large communities of people who swear that oils have healing powers and would even go as far as to replace traditional medicines or treatments with essential oils.

  4. Shannon, I really enjoyed reading your post. Aromatherapy is widely known and is still used today. I was not aware that aromatherapy was used for the dead as well. It really helped that you talked about the process of how aromatherapy works and what leads people to believe in it. I also liked how you talked about the placebo effect. It is interesting to read all of the factors that could lead people to a healthier immune system.

  5. Really interesting article! I loved learning the history of peoples’ relationship with aromatherapy. Overall, I still think it can be useful to put someone in the right mindset to like a healthier or happier life (kind of like a snowball effect where if you do one self care activity you might be more likely to eat healthier or spend less time on your bad habits) or as a mild placebo effect. So long as you aren’t missing out on important health- or self-care because you’re replacing it with aromatherapy, it could be beneficial to certain people.

  6. I usually avoid making posts on topics I have already commented on, but I am a huge fan of aromatherapy. It is undeniable that nice smells appeal to us, nothing is better than coming home from a long day, and just breathing in your favorite smell. I has a powerful ability to calm a person, help them focus, and I’m sure could be paired with other cues to promote other desired responses. However, the applications of effective aromatherapy are extremely limited. Aromatherapy won’t cure your cancer, or heal your wounds. It certainly doesn’t purify souls. Aromatherapy is an ancient practice, and sadly that means it often crosses into a supernatural realm. Let’s just try to enjoy it for what it is, a nice smell.

  7. I find it interesting that there was a journal that stated that it had “potential” to help with depression, yet people have taken that as fact. I think people want to believe that things such as aromatherapy will work as an alternative to other forms of medicine. I also find it interesting that people have taken this idea and ran with it based off of having potential yet people would be more skeptical with other forms of medicine such as a new drug or surgery in the same position.

  8. I would’ve never guessed that aromatherapy would be an extraordinary belief since it is so widely practiced and believed. There are so many stores that smell essential oils for different purposes and so many people are really into aromatherapy. I was shocked to read that there is such little scientific evidence behind this, because it’s just something that I had accepted to be effective. I remember reading a lot of articles stating that eucalyptus oil can get rid wheezing and soothe asthma attacks when I had an allergic reaction over winter break and I couldn’t get to the doctors until the next morning. Now that I know that there isn’t really evidence to back it up, this can be extremely dangerous, because some people will could try to fix medical issues with aromatherapy instead of getting real medical treatment.
