Background & Aims: Depression is a common and debilitating disease that affects more than 300 million people worldwide (1). Depressive disorder is associated with unemployment, poor physical health, impaired social functioning and, especially in severe cases, with suicide. Therefore, depressive disorder carries a great burden due to the increase in economic costs and the loss of productivity and demand in health care, not only on individuals but also on the whole society (3). with depression also stated that they are classified as "common mental disorders" (4) Although these symptoms have specific diagnostic thresholds, they affect the quality of life and social and occupational performance and cause pressure on the person and the economic status of the population in the scale becomes larger (5). Various methods have been proposed and recommended to reduce anxiety and depression and improve mental health. One of the non-medicinal, simple and uncomplicated methods for treating anxiety and depression is aromatherapy or aromatherapy, which is the use of volatile oils or aromas extracted from flowers and aromatic plants in order to promote therapeutic goals, and through inhalation, Inhalation and massage are performed (6). Aromatherapy using aromatic plant oil is effective in reducing anxiety, pain, fatigue and healing skin wounds (7-9). Massage is one of the most important non-drug interventions to reduce the level of anxiety (10). The use of aromatic plant oils in the traditional medicine of Asian nations including China, India and Iran has a history of thousands of years (12). In this regard, jasmine oil is widely used in different countries in order to benefit from its benefits. Jasmine oil is a sweet smelling substance that is prepared from the jasmine plant (Jasminum officinale) (14). Widely used in aromatherapy, this type of essential oil contains aromatic plant compounds that have various health benefits, including skin care and stress reduction. This plant has analgesic, sedative and anti-depressant properties (15). The results of some studies show that aromatherapy can help improve the physiological and psychological indicators of sick people (18, 19). There is little information about the effect of aromatherapy on anxiety, depression and mental health of people suffering from depression. On the other hand, the use of different medicinal plants in a traditional way has become widespread in the treatment of many ailments and also in the improvement of mental states. By reviewing the research done, no research was found that investigated the benefits of relaxation massage with jasmine oil to reduce depression and improve mental health. Therefore, considering the lack of sufficient information in this field, the need to conduct more studies is felt. Considering the benefits of massage therapy on many symptoms and psychological problems on the one hand and the positive effects of jasmine oil on the other hand, Does six weeks of relaxation massage with jasmine oil affect the level of anxiety, depression and mental health of middle-aged women with depression? Methods: In this semi experimental study, 30 middle-aged women (age 42 ± 3.06 years) with depression based on the DSM-IV standard were randomly divided into 2 groups; control and relaxation massage with jasmine oil. Experimental group received Relaxation Massage with Jasmine Oil for 6 weeks, 3 sessions per week and 30 to 45 minutes each session. Spiel Berger, Beck and GHQ28 questionnaires were used to measure anxiety, depression and mental health of the subjects before and after the intervention. Data were analyzed by independent t-test and dependent t-test at the P<0.05. Results: The results showed that relaxation massage with jasmine oil improved the mental health of middle-aged women with depression compared to the control group (P=0.001). Also, the mean score of depression and anxiety was significantly lower in relaxation massage with jasmine oil group compared to the control group (P=0.001). Conclusion: The results of the present study showed that six weeks of relaxation massage with jasmine oil significantly reduced the anxiety of middle-aged women with depression. The results of this research are consistent with the findings of Alavi et al. (2013) who showed that aromatherapy with jasmine oil significantly reduces anxiety in pregnant women (20). Some aromatherapy studies show that essential oils, including jasmine oil, may affect biological factors such as heart rate, stress level, blood pressure, breathing, and immune system function (14). In aromatherapy, the absorption of jasmine oil through the skin causes a message to be transmitted to the brain area called the limbic system. This region is involved in the control of emotions and also affects the nervous system (22- 24). Therefore, it is possible that jasmine oil along with massage has led to the reduction of anxiety in middle-aged women with depression through the effect on the limbic system. Also, the present findings show that six weeks of relaxation massage with jasmine oil significantly reduced depression in depressed middle-aged women. There is evidence that aromatherapy can effectively reduce symptoms of depression. The stimulating and activating effect of jasmine oil can be useful for relieving depression and improving mood (14). When inhaled, jasmine oil affects brain activity and mood, and participants reported feeling more positive and energetic (22). The results of the present research also indicate the beneficial effects of jasmine oil in reducing depression symptoms. Finally, the present findings show that six weeks of relaxation massage with jasmine oil significantly improved the mental health of middle-aged women with depression. This finding is consistent with the results of Shahrjardi and Darvish (2013), who showed a significant improvement in the mental health of women with cancer after the massage period (29). Jasmine flower contains benzyl acetate, lymal alcohol, benzylic alcohol, indole oleanolic acid, dacosterol, hesperidin and active compounds such as alkaloids, flavonoids, saponins and tannins and jasmine (30-32). It is possible that jasmine oil along with massage has led to a significant improvement in the mental health of middle-aged women with depression through the compounds found in jasmine. In the present research, after six weeks of relaxation massage with jasmine oil in middle-aged women suffering from depression, the level of mental stress has decreased and the patients have the feeling that they have the same abilities as other people and thus feel more self-confidence. have obtained Therefore, relaxation massage with jasmine oil can help to improve the mental health of patients suffering from depression, and as a behavioral intervention and complementary treatment, it can play an important role in improving the mental health of patients. One of the positive effects of relaxation massage with jasmine oil is regulating the amount of neurotransmitters in nerve cells and as a result establishing balance in the person's nervous function and reducing mental abnormalities. By performing a relaxation massage with jasmine oil, the level of stress decreases due to the secretion of a number of hormones from different glands and the effect on the nervous system, as well as increasing the consumption of oxygen (14). There were also some limitations in the present research, including the non-use of other massage methods. Overall, one can benefit from its mental health benefits by using relaxation massage with jasmine oil, as shown by the present findings. According to the findings of this research, according to the results of the research, it seems that relaxation massage with jasmine oil can help reduce anxiety and depression and improve the mental health of middle-aged women with depression. Therefore, according to the findings of the research, it is suggested that middle-aged women suffering from depression receive relaxation massage with jasmine oil to reduce the negative consequences of depression.
