Can Aromatherapy Be Used as an Adjunctive Tool for Pain Management in Palliative Care?

Pain, a common symptom among patients receiving palliative care, often remains under-treated. This is partly due to its complex nature, which makes it challenging to manage using only conventional medicine. As health professionals and scholars delve deep into alternative therapies, aromatherapy has emerged as a feasible adjunctive tool. With its potential benefits including pain relief and improved psychological wellbeing, it may offer a transformative approach to pain management in palliative care.

Understanding Pain in Palliative Care

Before we delve into the role of aromatherapy in pain management, it’s important to understand the pain that patients in palliative care face. Pain in palliative care isn’t just a physical sensation. It’s a complex interplay of physical discomfort, emotional distress, and psychological torment.

For patients with life-limiting illnesses like cancer, pain is a common companion. It’s not just a symptom of the disease itself, but also a side effect of treatments such as chemotherapy and radiotherapy. Pain can also stem from other sources, like bedsores from long stays in bed, or neuropathic pain from damaged nerves.

Despite advances in pain management, many patients still suffer. A review on PubMed Central (PMC), a free archive of biomedical and life sciences journal literature, reported that up to 50% of cancer patients and up to 80% of advanced stage cancer patients suffer from pain. This demonstrates a clear need for more effective pain management strategies in palliative care.

Aromatherapy: An Overview

Aromatherapy is a holistic healing treatment that uses natural plant extracts, or essential oils, to promote health and wellbeing. It’s often associated with complementary and alternative medicine (CAM), and has long been used to help alleviate a variety of conditions, from stress and anxiety to certain physical ailments.

When you use Google to search for ‘aromatherapy,’ you’ll find a wealth of information with a simple click. Aromatherapy works through the sense of smell and skin absorption. Methods include diffusing the oils into the air, inhaling them directly, or applying them to the skin during a massage.

Clinical trials and research studies have suggested that aromatherapy can have health benefits. For example, a systematic review in the PubMed database found that aromatherapy can help reduce anxiety. Another trial, indexed in PMC, suggested that it could also help improve sleep quality.

Applying Aromatherapy in Pain Management

If you’re familiar with the soothing effects of a lavender-scented candle or the invigorating aroma of peppermint, you’ve experienced a hint of the potential of aromatherapy. But can these aromatic oils really help manage pain in palliative care patients?

Several trials and studies suggest that they can. For instance, a group of scholars conducted a randomized controlled trial to determine the effect of aromatherapy massage on pain in cancer patients. The results, published in PubMed, indicated that patients in the aromatherapy group reported significant reductions in pain compared to the control group.

A similar trial investigated the effects of aromatherapy on pain and depression in patients undergoing palliative care for terminal cancer. The study, published in PMC, found that aromatherapy effectively reduced pain and depression in the intervention group.

While these results are promising, it’s important to remember that aromatherapy is not a standalone treatment for pain. Instead, it’s an adjunctive tool that can complement existing pain management strategies.

Safety and Considerations for Aromatherapy Use

While aromatherapy seems to hold promise as an adjunctive tool for pain management in palliative care, there are some considerations to bear in mind.

First, not all essential oils are suitable for everyone. Some individuals may have allergic reactions to certain oils, while others may find certain scents unpleasant or even nauseating. It’s crucial to consider patient preferences and potential allergies before starting aromatherapy.

Second, it’s essential to use high-quality, therapeutic-grade essential oils. Some products on the market are synthetic or diluted and may not provide the same therapeutic benefits.

Finally, it’s important to remember that while aromatherapy may help alleviate pain and other symptoms, it’s not a cure-all. It should be used as part of a comprehensive care plan, along with traditional medical therapies and other complementary therapies, if suitable.

In conclusion, the potential benefits of aromatherapy in palliative care are undeniable. However, like any therapy, its use should be carefully considered and tailored to the individual patient’s needs, preferences, and overall care plan. This will ensure that patients receive the most appropriate, effective, and holistic care possible.

Essential Oils Commonly Used in Aromatherapy for Pain Management

The role of essential oils in aromatherapy is crucial. Each essential oil has unique properties that can offer a variety of therapeutic benefits. For example, lavender oil is known for its calming effects and may help reduce anxiety and improve sleep. Peppermint oil, on the other hand, is invigorating and may help ease headaches and muscle tension.

When it comes to mitigating chronic pain, some essential oils have shown promising results. According to a systematic review on PubMed, eucalyptus oil, for instance, has potent anti-inflammatory and analgesic properties that may help alleviate pain. Frankincense oil, another example, is known for its anti-inflammatory effects and may help reduce joint pain and swelling, making it potentially beneficial for arthritis patients.

The use of essential oils is not limited to these examples, though. A study published in Google Scholar explored the pain-relieving effects of various essential oils, including rosemary, chamomile, and clary sage, in palliative care patients. The researchers observed significant reductions in pain scores in the group treated with aromatherapy.

However, it’s crucial to note that more rigorous scientific studies, such as a meta-analysis, are needed to affirm these preliminary findings. Moreover, any use of essential oils should be under the guidance of a healthcare professional to avoid adverse reactions.

The Role of Aromatherapy in Enhancing Quality of Life for Palliative Care Patients

Beyond pain management, aromatherapy can also contribute to enhancing the quality of life for palliative care patients. As patients navigate through the stages of a life-limiting illness, they often grapple with symptoms beyond physical pain, such as anxiety, depression, and insomnia.

For instance, a PubMed article highlighted the potential of aromatherapy in reducing anxiety and improving sleep quality among cancer patients undergoing chemotherapy. Another PMC free article reported that aromatherapy massage helped mitigate feelings of depression in palliative care patients.

Moreover, aromatherapy may also help manage treatment-related side effects like nausea and vomiting. According to a systematic review on PubMed, the inhalation of certain essential oils, such as ginger and spearmint, helped reduce chemotherapy-induced nausea and vomiting in cancer patients.

However, as with any therapy, patient preferences and individual responses should always be considered. For some, aromatherapy may provide a much-needed respite from the distressing symptoms of their illness or treatment. For others, the scent of certain oils may trigger discomfort or allergic reactions. Therefore, personalized approaches to aromatherapy are key to maximizing its potential benefits.


In the realm of palliative care, where the objective is to enhance comfort and quality of life, alternative and complementary therapies like aromatherapy can play a significant role. The potential of essential oils to alleviate pain and improve psychological well-being can contribute to a more holistic approach to patient care.

However, it’s important to emphasize that aromatherapy is not a panacea. It is an adjunctive tool meant to complement, not replace, conventional treatments. Its use should always be under the guidance of healthcare professionals who can consider individual patient needs, monitor responses, and manage potential side effects.

The promising findings from various studies underscore the need for more robust research, such as randomized controlled trials and meta-analyses, to further explore the extent of aromatherapy’s benefits and its optimal application in palliative care. With continued research and careful application, aromatherapy has the potential to significantly enrich the care and comfort of patients in their final stages of life.
