Chaihushugan Decoction and Wen Dan Tang for Insomnia

Recruiting now · Not applicable

Conditions studied: Insomnia, Sleep Wake Disorders

In brief

This study aims to evaluate the clinical effectiveness of Traditional Chinese Medicine (TCM) in treating sleep disorders, specifically chronic insomnia. While conventional TCM treatments often rely heavily on subjective patient feedback, this clinical trial incorporates objective diagnostic tools, including Digital Polysomnography (PSG) and actigraphy, to gather data-driven sleep quality metrics. Participants will be randomly assigned to receive either Chaihushugan Decoction or Wen Dan Tang for an 8-week treatment period. Subjective improvements will be tracked using standardized clinical questionnaires such as the Insomnia Severity Index (ISI) and Pittsburgh Sleep Quality Index (PSQI). The findings from this trial will help clarify the scientific basis and treatment pathways of these two classic herbal formulations for sleep management.
