Argument167: 192 words
A folk remedy* for insomnia, the scent in lavender flowers, has now been proved effective. In a recent study, 30 volunteers with chronic insomnia slept each night for three weeks on lavender-scented pillows in a controlled room where their sleep was monitored. During the first week, volunteers continued to take their usual sleeping medication. They slept soundly but wakened feeling tired. During the second week, the volunteers discontinued their medication. As a result, they slept less soundly than the previous week and felt even more tired. During the third week, the volunteers slept longer and more soundly than in the previous two weeks. This shows that over a short period of time lavender cures insomnia.
*A folk remedy is usually a plant-based form of treatment common to traditional forms of medicine, ones that developed before the advent of modern medical services and technology.

The argument give the process and change of 30 patients of chronic insomnia sleeping with the lavender-scented pillows in a controlled rooms in order to assert the effect of the plant-based form of treatment, insomnia can cure the problems of sleeping. The evidence seems to be reasonable, however, oversimplified the concluding. All of the flaws will be presented as following.
In the first place, is the controlled room is the same as the place in which volunteers slept before the experiment? Maybe the room for this experiment is better conditioned with comfortable beddings, temperature and moisture and so forth. In another word, all of the negative factors of the slept are dispersed and the so-called patients sleep well. If the experiment is taken in the patients’ room, the result will be more reliable.
In the second place, all of what the doctor does to the volunteers are known and the effect of psychology can not be ignored. At first, when a person is told to take chronic insomnia slept and given sleeping medication, it is easy to sleep soundly and weaken feeling tired because of the psychological comfort. In addition, it is the same when the medication is discontinued and the testers worry about their sleeping because of the reliance on the medication. Results from the experiment with continuous medication, some of them are drug and others are vitamin which are necessary in daily life, will be trustable.
Moreover, the good sleeping quality is meaningless. Does the medicine play a roll after two weeks or the perfect environment promote the slept, or the insomnia solve the problems? There is no way to make a conclusion rightly, although there is a experiment took.
The last but not the least, the most important thing, the contrast of the experiment, is not referred here. The control experiment should be taken in the same room, during the same or similar time, with the same volunteers, as well as without any medicine or treatment.

After all analysis above, it is obviously that the arguer had better to improve the experiment in many aspects. Assuming that there is no problem neither in the choice of the experimental place nor in the affection of the psychology, if results that getting from three weeks are the same as that showed in this experiment while the control experiment is resulted oppositely, the arguer did it with a right and exciting approach to the testing of the treatment and, of course, we can condclude that the folk remedy for insomnia is effective.
