• 共用题干Aromatherapy(芳香疗法)
  1.Aromatherapy is a form of alternative medicine which is based on the use of very concentrated essential oils from the flowers,leaves,bark,branches or roots of plants which are considered tohave healing properties.In aromatherapy these powerful oils are mixed with other oils,such as almond(杏仁)oil,or the are diluted(稀释)with water.These solutions(溶液剂)can be rubbed on the skin,sprayed in the air,or applied as a compress（敷药）.
  2.Many people have aromatherapy massages（按摩）,and depending on the treatment a person is having,the aromatherapist will massage the oil into the hands or shoulders.The massage is smooth and flowing,as it is designed to create a sense of relaxation and calm.The sessions are tailored to the individual's health and mood at the time,so every session is unique.
  3.Practitioners of aromatherapy believe that the aroma of the essential oils directly stimulates the brain or that the oils are absorbed through the skin into the bloodstream,where they can affect the whole body and promote healing.Other claims in support of aromatherapy are that it aids digestion,improves the functions of respiratory system,reduces muscular aches and pains,and promotes muscle relaxation and tone.It has also been argued that aromatherapy can improve circulation,lower blood pressure,and help combat insomia （失眠）and other stress-related disorders such as tension headaches , anxiety , and mild depression.
  4.However,while aromatherapy may have real effects that promote a sense of well-being,some traditional medicine practitioners remain doubtful about its powers.While research has confirmed that aromatherapy does have some positive short-term effects on most people,it also suggests that aromatherapy is not an actual science or medicine that should be used to treat illness.Furthermore,not all aromatherapy is considered beneficial to health.There are precautions which should be taken before having aromatherapy because some oils can have negative effects on people with certain medical conditions.The study of aroma-therapy is relatively new and unexplored.More research needs to be conducted to make scientific conclusions about its use and effects.
