问题     Think of lavender today and up come images of old-world cottage gardens thick with nodding hollyhocks and pink roses round the door. It’s a prime player in lots of potpourri concoctions for that reason. But recently it’s been seen as more than just a pretty scent.
    In the last few years, clinical trials have been conducted on essential oil of lavender. Scientists have been studying its potential in the treatment of various health problems.
    In the days of folk medicine lavender oil was considered to be one of the most useful all-round remedies, particularly for its soothing and antiseptic qualities. It was used for a wide range of treatments : a drop on a restless child’s pillow for a good night’s sleep or a little massaged into the temples to relieve a headache or mild depression. It was even used as a rough-and-ready antiseptic by soldiers in the First World War. And it goes back much further than that: the Romans used the oil so widely to perfume their baths that its Latin name Lavandula, derives from their verb to bathe.
    Lavender’s healing properties were first discovered by accident. In 1910 a French chemist and perfumer burnt himself in a laboratory explosion. He plunged his singed hand into the nearest liquid which happened to be lavender essence and was so impressed with the results that he devoted 50 years to studying the properties of essential oils.
    Pharmaceutical companies—influenced by growing ecological concerns as the rest of us—have begun to reappraise many traditional treatments. Some of the most effective drugs we use in modern medicine derive from natural remedies.
