“…Despite the popularity of chamomile as a sleep aid [ 11 ] there are no published studies examining chamomile for primary insomnia or for any type of chronic sleep disorder. Two other clinical studies have examined the sedative effect of chamomile as a secondary outcome in healthy volunteers and in women with menopausal symptoms [ 16 , 17 ]. 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.…”

“…Kupfersztain and colleagues [ 16 ] found that 12 weeks of an herbal extract for hot flashes that contained chamomile alleviated sleep disturbances and fatigue more than placebo. In another study, adults without sleep complaints who received chamomile jelly had higher peripheral skin temperature, higher ratings of relaxation, and, in men, lower sleep diary ratings of sleep onset latency, nighttime wakefulness, and morning sleepiness more than placebo [ 17 ].…”

BackgroundDespite being the most commonly used herbal for sleep disorders, chamomile's (Matricaria recutita) efficacy and safety for treating chronic primary insomnia is unknown. We examined the preliminary efficacy and safety of chamomile for improving subjective sleep and daytime symptoms in patients with chronic insomnia.MethodsWe performed a randomized, double-blind, placebo-controlled pilot trial in 34 patients aged 18-65 years with DSM-IV primary insomnia for ≥ 6-months. Patients were randomized to 270 mg of chamomile twice daily or placebo for 28-days. The primary outcomes were sleep diary measures. Secondary outcomes included daytime symptoms, safety assessments, and effect size of these measures.ResultsThere were no significant differences between groups in changes in sleep diary measures, including total sleep time (TST), sleep efficiency, sleep latency, wake after sleep onset (WASO), sleep quality, and number of awakenings. Chamomile did show modest advantage on daytime functioning, although these did not reach statistical significance. Effect sizes were generally small to moderate (Cohen's d ≤ 0.20 to < 0.60) with sleep latency, night time awakenings, and Fatigue Severity Scale (FSS), having moderate effect sizes in favor of chamomile. However, TST demonstrated a moderate effect size in favor of placebo. There were no differences in adverse events reported by the chamomile group compared to placebo.ConclusionChamomile could provide modest benefits of daytime functioning and mixed benefits on sleep diary measures relative to placebo in adults with chronic primary insomnia. However, further studies in select insomnia patients would be needed to investigate these conclusions.Trial RegistrationClinicalTrials.gov Identifier NCT01286324

“…In a study of healthy adults reporting no sleep problems those receiving chamomile jelly reported higher ratings of relaxation, lower sleep onset latency, night-time wakefulness, and increased morning sleepiness compared to placebo (Kakuta et al, 2007). Although the neural mechanism is at this time unclear, studies suggest that the sedative effects result from modulation of y-aminobutryic acid (GABA) receptors (Viola et al, 1995).…”

Acute consumption of Peppermint and Chamomile teas produce contrasting effects on cognition and mood in healthy young adults

This study aimed to assess the acute effects of Peppermint and Chamomile herbal teas on cognitive performance and mood in healthy young adults. A single factor independent groups design was employed. One hundred and eighty undergraduate students volunteered to take part in the study for which they received course credit. Participants were randomly allocated to one of three treatments: Peppermint tea, Chamomile tea or hot water (Control). Mood scales were completed and participants then consumed their drink over a ten minute period and rested for twenty minutes. Cognitive performance was assessed using a tailored version of The Cognitive Drug Research (CDR) computerised assessment system. Post testing mood scales were then completed. Data were analysed using independent groups ANOVAs followed by Tukey post hoc comparisons. The analysis revealed that Peppermint tea significantly improved long term memory and speed of memory compared to both Chamomile and control treatments. Chamomile tea significantly slowed speed of attention and impaired working memory compared to the Peppermint treatment. Peppermint tea significantly increased subjective alertness compared to the Chamomile and control conditions. Chamomile significantly increased subjective calmness compared to the Peppermint treatment. The data show that acute consumption of Peppermint and Chamomile teas can impact on cognition and mood in healthy adults in contrasting directions. The enhancing and arousing effects of Peppermint and calming/sedative effects of Chamomile observed are in keeping with the purported properties of these herbs and suggest beneficial effects can be drawn from their use.
