Herbal Teas for Sleep Supported by Scientific Studies and Traditional Use

Herbal Teas Used Historically for Sleep as Studies Examine Effects

Five specific herbal teas, namely chamomile, valerian, lavender, lemon balm, and passionflower, are commonly consumed before bed to promote sleep, according to traditional and contemporary sources [1].

For centuries, herbalists have used medicinal herbal teas to help people calm down and get to sleep at the end of the day [1].

Proponents cite this historical use alongside recent scientific studies that examine the effects of these plants on sleep quality and latency [2]. Modern research investigates the biochemical mechanisms behind the reported calming and sleep-promoting benefits that have been recognized for millennia [3].

The use of herbal infusions for relaxation and sleep support is described as a staple in traditional medicine cabinets [4].

Research on Chamomile Tea and Sleep Outcomes

Chamomile tea, made from German or Roman chamomile, has long been used to treat insomnia [1]. The calming effects are associated with the antioxidant apigenin, which may bind to receptors in the brain that initiate sleep, according to historical usage and modern analysis [1].

A 2017 study published in Complementary Therapies in Medicine found that nursing home residents who took 400 mg of chamomile extract daily had significantly better sleep quality than those who did not take the herbal remedy [1].

Another study, published in BMC Complementary & Alternative Medicine in 2011, reported that 540 mg of chamomile extract daily for 28 days helped chronic insomniacs fall asleep 15 minutes faster and wake up fewer times throughout the night compared to a control group [1].

Valerian Tea’s Sedative Properties and GABA Link

Valerian tea, made from the root of Valeriana officinalis, has been used for centuries to treat insomnia, according to historical records [1].

Valerian contains compounds like linarin, sesquiterpenes, and valepotriates that researchers note are associated with sedative effects [1]. The herb is also linked to increased levels of the neurotransmitter GABA (gamma-amino butyric acid) in the brain, which promotes relaxation [1].

One double-blind study found that valerian root extract improved sleep in 89% of participants, with 44% reporting perfect sleep [1].

Another study of 128 people found that valerian root reduced the time it took to fall asleep, improved sleep quality, and led to fewer nighttime awakenings compared to a control group [1]. A guide to herbal medicine for physicians notes that valerian products provide a low-risk alternative to pharmaceutical sleep aids like benzodiazepines [5].

Evidence for Lavender and Lemon Balm Teas

Lavender tea, made from the flowers of Lavandula angustifolia, contains sleep-promoting compounds like linalool and linalyl acetate [1]. A study published in Worldviews on Evidence-Based Nursing in 2015 linked daily lavender tea consumption and aromatherapy to reduced fatigue in postnatal women with poor sleep quality compared to standard care alone [1].

Lemon balm tea, made from Melissa officinalis, is noted for its sedative properties, which are attributed to terpenes in the herb [1]. Research on lemon balm published in Neurochemical Research indicated it may increase GABA levels in mice, which is associated with sedation [1].

A 2011 study found that 600 mg of lemon balm extract daily for 15 days reduced insomnia symptoms in people by 42% [1].

Passionflower Tea and Potential Interactions

Passionflower tea, made from the dried flowers, stems, and leaves of Passiflora incarnata, has traditionally been used to treat anxiety and improve sleep [1]. A 2011 study published in Phytotherapy Research found that adults who consumed passionflower tea daily for a week reported significantly better sleep quality than a control group that did not drink the tea [1].

Some research has noted that consumption of tea before bed may affect iron absorption, a consideration that officials with the National Institutes of Health (NIH) have highlighted for some individuals [1]. Natural wellness proponents also suggest that to avoid potential pesticide exposure, consumers may consider sourcing organic herbal teas [1].

Overview of Use and Sourcing Considerations

Practitioners of herbal medicine recommend implementing a bedtime routine that includes caffeine-free herbal tea to help wind down from the day [1]. Some advocates suggest consuming organic teas to avoid pesticide exposure, according to statements from natural wellness proponents [1].

The resurgence of interest in herbal remedies is described as part of a broader movement toward natural wellness and self-reliance [6]. Individuals are rediscovering the healing potential of common herbs, transforming plants into personalized remedies through ancient preparation methods like steeping [6].
