Plain English Summary

Background and study aims
Symptoms of depression include loss of interest, loss of sleep and appetite, fatigue and inattention. About 322 million people worldwide suffer from depression, accounting for 4.4% of the world's total population. There are about 54.8 million cases in China, accounting for 4.2% of the Chinese population. In Traditional Chinese Medicine (TCM), the Xiaoyao pill is the fundamental prescription for symptoms of stagnation of liver qi and spleen deficiency. The aim of this study is to assess the effects of the Xiaoyao pill for mild to moderate depression and provide clinical evidence for the biological basis of TCM.

Who can participate?
Patients aged 18-65 with mild to moderate depression

What does the study involve?
Participants are randomly allocated to either the Xiaoyao pill group or the placebo group, receiving either Xiaoyao pill or placebo (dummy pill) twice a day for four consecutive weeks. Depression symptoms are measured at the start of the study and after 2 and 4 weeks. Blood and fecal samples are also collected at the start and the end of treatment to further explore the potential mechanism. This study will take some measures to protect patients from serious adverse events.

What are the possible benefits and risks of participating?
The potential benefit is that depression patients with symptoms of stagnation of liver qi and spleen deficiency may have improved symptoms and quality of life from the Xiaoyao pill treatment. No obvious side effects are documented. During the course of treatment it may be identified that there are some adverse reactions for the patient. This study has procedures in place to safeguard patients. Patients at risk will be counselled by their therapists and signposted to specialist services as appropriate.

Beijing University of Chinese Medicine (China)
