Ancient herbal sleep aids put to the test with modern brain monitoring
NCT ID NCT07735390
First seen Jul 30, 2026 · Last updated Aug 07, 2026 · Updated 2 times
Summary
This pilot trial compares two traditional Chinese herbal formulas — Chaihushugan Decoction and Wen Dan Tang — for treating chronic insomnia. Adults with chronic insomnia will take one of the two herbal granules three times daily for eight weeks. Unlike many herbal studies, this one uses objective sleep trackers like polysomnography alongside standard questionnaires to measure sleep quality. The goal is to see which formula may work better and to build scientific evidence for these ancient remedies.
