Abstract
Aromatherapy is a complementary healing therapy that uses aromatic
essential oils to improve the health of the body and mind. Essential oils with healing
properties, like geranium oil, rosemary oil, lavender oil, patchouli oil, and others, have
been used to treat cancer. Cancer is often treated using chemotherapy and/or radiation
therapy. Nausea and vomiting are often side effects of chemotherapy and radiotherapy.
Subsequently, these cancer therapies lead to various psychological disorders, such as
stress, anxiety, and depression, in cancer patients. Hence, the a need to assist cancer
patients in overcoming these disorders. Aromatherapy, which is a blend of essential
oils, has been reported to improve disorders that arise during complicated cancer
therapies such as chemotherapy and radiation. Research on cancer populations has
revealed that patients exposed to essential oils via inhaler devices had reduced anxiety,
stress, nausea, and poor sleep. The effects of aromatherapy are reported to be due to the
binding of chemical components in the essential oil to receptors in the olfactory bulb,
impacting the brain’s emotional center, the limbic system. Aromatherapy has also been
reported to relieve pain, muscular tension, and fatigue. Aromatherapy practitioners treat
specific conditions using various combinations of oils and different modes of
application. Aromatherapy can thus be used as a potential supplement treatment to
improve complications in cancer; however, further studies are needed to estimate the
protocol and standard dosage. Given the difficulties of cancer treatment, aromatherapy
can play an important role in treating patients' psychological aspects.
