What the rows share
From the rowsThe best-graded row, grade D, is a crossover trial of 106 people (2023) and reported mixed results.
The rows run from 15 to 106 people, published from 2015 to 2023: 2 single studies.
The rows
1 improved · 1 mixed- DGrade DNon-REM sleep time and self-rated sleep quality · Improved
Open-label trial · n 15 · 2015 · Adults with poor sleep (PSQI 6 or higher), mean age about 37 (Japan)
50 mg 30 minutes before bed · 1 week per period, 1-week washout
Non-REM sleep time rose 7.6% vs placebo (p < 0.01) on single-channel home EEG, but most of the added non-REM sleep was light sleep and delta-wave power, a marker of deep sleep, did not differ from placebo. The PSQI improvement with the extract was only a non-significant trend (p = 0.10).
