Outcome Measures

Primary Outcomes (1)

  • Change From Baseline of Chamomile Extract on Measures of Sleep at Day 28.

    Change from baseline of chamomile extract, three tablets (equivalent to 7.5 g of dried herb) p.o. twice times daily versus placebo on the following sleep measures at 28 days: * the change from baseline of daily self-report of sleep as assessed by a sleep diary that includes determination of: (i) sleep efficiency, which equals "The total sleep time divided by time-in-bed, multiplied by 100." This measure is our primary aim (SE).
