Natural Health News – Two recent studies have shown that aromatherapy, whether by inhalation or massage, can lower blood pressure and improve sleep quality.
Both studies involved mature women with heart conditions.
In the first study, published in the journal Evidence Based Complementary and Alternative Medicine, patients with diagnosed coronary artery diseases, who underwent a stent insertion during coronary angiography, were allocated to either an aromatherapy group or a standard nursing care group.
The aromatherapy treatment consisted of 10 deep inhalations of an essential oil blend (lavender, Roman chamomile and neroli essential oils in a 6:2:0.5 ratio) 2 drops of which had been dropped on aroma stones, before and after the procedure. In addition the aroma stone was placed under the patient’s pillow until the following morning.
The authors note that “Lavender suppresses heart stimulation and lowers blood pressure; therefore, it is useful in the treatment of heart acceleration and high blood pressure. Chamomile has a calming effect and is effective in relieving anxiety and stress, and neroli has a calming effect and is effective in treating insomnia”.
Compared to standard nursing care, treatment with aromatherapy effectively reduced the anxiety levels and increased the sleep quality in those who received it.
In addition while blood pressure in the nursing care group increased immediately before and after the stent procedure (in comparison to the baseline measurement taken at admission), in the aromatherapy group, blood pressure in the aromatherapy treatment group, was approximately 12mmHg lower than at baseline, before and after the procedure.
Similar findings in another study
In a second study in the same journal a once a week massage and the use of a body cream containing essential oils prescribed by an aromatherapist once a day helped lower blood pressure and improved sleep quality in middle-aged hypertensive women.
In this study the women were allocated into the aromatherapy massage group, the placebo group and the no-treatment control group. Interestingly the placebo group also received a massage and a body cream but with synthetic fragrance in it.
The aromatherapy massage oil and body cream used a blend lavender, marjoram, ylang-ylang, and neroli (in a ratio of 20:10:15:2 diluted to 3% in both products)
Blood pressure, pulse rate, sleep conditions, and 24-hour ambulatory blood pressure were monitored before and after the experiment.
The investigators noted significant differences in blood pressure and sleep quality among the groups. For instance the aroma massage group showed an approximate reduction of 15mmHg in systolic blood pressure, more than double the 6mmHg reduction seen in the placebo/synthetic fragrance group. Reductions in blood pressure were quickly apparent immediately after the use of the aromatherapy blend.
In terms of sleep quality, the aromatherapy massage group showed an improvement, while the placebo and no-treatment groups failed to do so. Other benefits were less pronounced.
The researchers note that previous studies have shown that massage relaxes the autonomic nervous system, lessens stress, reduces blood pressure, reduces depression and boosts immune-system function. They said also that they believed that the oils worked synergistically to lower blood pressure.
