摘要
Background: Since the outbreak of the pandemic started, an increase in the number of sleep disorders, including insomnia and poor sleep quality, has been seen. The pattern will probably continue. Methods: This study focuses on the preparation and clinical testing of Poria cocos extract in treating suboptimal sleep quality. The optimal extraction method utilized a 75% ethanol concentration, and the clinical investigation involved subjects with defined poor sleep taking 800 mg of the extract nightly, assessed using the Sleep Questionnaire and polysomnography. The non-parametric Wilcoxon signed-rank test was used for statistical analysis due to the non-normal distribution of the collected data. Results: The study involved 21 insomnia sufferers with a mean age of 55 who were administered Poria cocos extracts. The findings of the study indicate a statistically significant rise in the overall duration of sleep (from 327.395 ± 43.2 min to 356.516 ± 63.21 min, p = 0.014). Additionally, there was a notable decrease in the level of arousal during sleep (from 76.316 ± 44.78 min to 47.989 ± 42.38 min, p = 0.009), and an improvement in the sleep severity index of the sleep questionnaire test. Conclusions: Poria cocos as a natural substance could improve quality of sleep, based on the findings. The study investigates Pachymic acid, a substance found in Poria cocos, as a potential indicator for the development of sleeping aids.
