Aromatherapy sessions which make use of essential oils could have a beneficial effect on a person's heart health, according to new research
Many people have the spa treatment to help lower their stress levels, but doctors at Taipei Medical University found that exposure to aromatherapy oils for less than an hour could help lower blood pressure and heart rate.
However, the technique should be used in moderation.
Dr Kai-Jen Chuang, a researcher at the educational establishment, said: "The most interesting finding of our study is that exposure to essential oil for over an hour was associated with elevated blood pressure and heart rate."
Senior cardiac nurse at the British Heart Foundation Ellen Mason said that oils may help heart health, but people should concentrate on other factors that can help.
She listed giving up smoking, exercise and a balanced diet as positive ways of maintaining a healthy heart.
