Insomnia study

Do you find it difficult to get to sleep at night? Do you wake up too early, in the middle of the night or experience poor sleep quality? Are you always tired during the daytime? These are the exhausting symptoms of insomnia, which can affect not only sleep, but also your everyday life.

Sleep is fundamental for human health; however, insomnia symptoms are experienced by one third of Australians, having severe consequences on physical health, mental health, and daily performance. Insomnia is a multidimensional condition with consequences in daytime functioning, general wellbeing, disrupted mood and anxiety.

Our researchers at NICM Health Research Institute, Western Sydney University are looking for participants to volunteer for a study investigating the effectiveness of one of the best known Chinese herbal medicine treatments for insomnia. The treatment, called ZRAS, is composed of Spine Date Seed, Danshen Root and Chinese Magnoliavine Fruit, and has been widely use in hospitals and medical practices for over 30 years in China.

If you have experienced trouble sleeping you may be eligible to join the study.
