Somewhat similar to our results, both
of these studies demonstrated that chamomile had positive
effects on subjective sleep measures and in the case
of menopausal women experiencing hot flashes
improvements in fatigue as well. In contrast to our
study, which found a mixed effect of chamomile on
sleep measures, these studies both reported universally
positive effects of chamomile on sleep parameters. However,
sleep disturbances in menopausal women experiencing
hot flashes may be caused by distinctly different
mechanisms than those involved in primary insomnia.
Also, it is unclear what improvements in sleep measures
indicate in healthy volunteers without sleep
disturbances
