The Potential Benefit of Xiao-Yao-San Treatment in Patients With Insomnia

Exploring Changes in Sleep Assessment of Patients With Sleep-related Diseases Treated by Chinese Medicine

The investigators recruited patients ages 20-65 from 2 groups in Tainan Hospital. One was from a weight loss class, also called WLC, one was from our regular clinic. These patients have no history of schizophrenia, narcolepsy, neurological disease, alcohol and drug addiction but had Pittsburgh Sleep Quality Index (PSQI) scores for psychometric properties ≥ 5 between January 1 to November 30 of 2019. The study group were the patients who received XYS for 28 days and the control group were those who didn't receive any Chinese medicine but attended the WLC. Age, gender, personal biodata, polysomnography findings, and these subjective sleep questionnaires were collected. The Wilcoxon test was used to compare the difference in pre and post evaluation in two groups. After comparing the objective and subjective assessment between the better and poorer performance in the XYS group, we would find more suitable criteria for XYS in traditional Chinese medicine.
