Plain English summary of protocol
Background and study aims
Many people suffer from trouble with sleeping because of social, hormonal and behavioral changes. Hypnotics are the most common treatment for insomnia. More or less hypnotics may change the normal structure of sleep, which causes worse daytime impairment. Chinese herbs have fewer side effects than hypnotics. We will evaluate the effectiveness of Chinese herbs to improve the treatment of patients with insomnia.
Who can participate?
Any patient aged 18 to 65 years who has suspected insomnia within the recruited sites will be included in the study.
What does the study involve?
Participants will be randomly allocated to one of two groups. One group will receive Chinese herb granules and the group will get placebo (dummy) granules. All groups will be measured at the start of the study, after 4 weeks of treatment, after 8 weeks of treatment, just before both groups get one final treatment booster session, and again after 1 month to see if the treatment is effective in the long term.
What are the possible benefits and risks of participating?
Possible benefits for participants are deeper and longer sleep, and improvements of daily functioning that may have been affected by long-term sleep problems, like social functioning. We do not foresee any additional risks to patients in either group of the study.
Where is the study run from?
The study is set up and run by Beijing Hospital of Traditional Chinese Medicine affiliated to Capital Medical University, Beijing University of Chinese Medicine Dongfang Hospital and Beijing University of Chinese Medicine Dongzhimen Hospital.
