Chamomile is the most widely used tea for sleep, but it’s far from your only option. Several herbal teas contain compounds that interact with your brain’s calming pathways, and the best choice depends on whether you struggle more with falling asleep or staying asleep. Valerian root, passionflower, lemon balm, and lavender all have clinical evidence supporting their use as mild sleep aids.
Chamomile: The Go-To for Falling Asleep
Chamomile works because of a compound called apigenin, which binds to the same receptor sites in the brain that anti-anxiety medications target. These receptors are part of the GABA system, your brain’s primary “slow down” network. When apigenin locks into these sites, it promotes relaxation and drowsiness without the heavy sedation of pharmaceutical sleep aids.
To get the most out of chamomile, use one to two teaspoons of dried flowers in a cup of hot water (around 95°C, or just off the boil). Steep it covered for five to ten minutes. Longer steeping pulls more apigenin into the water. Covering the cup matters because the aromatic compounds that contribute to chamomile’s calming effect are volatile and will escape as steam if left uncovered.
Valerian Root: Stronger but Less Pleasant
Valerian root has more clinical research behind it than most herbal sleep aids. A meta-analysis in The American Journal of Medicine found that people taking valerian were 1.8 times more likely to report improved sleep quality compared to placebo. A 2025 scoping review of 51 randomized controlled trials identified valerian as having “substantial evidence” for both effectiveness and safety. It’s one of the more reliable options if chamomile alone isn’t doing enough.
The tradeoff is taste. Valerian root tea has a distinctly earthy, almost musty flavor that many people find unpleasant. Steep one teaspoon of dried root in just-boiled water for 10 to 15 minutes, covered. Valerian’s compounds are robust enough to handle near-boiling temperatures, unlike most herbal teas. Blending it with lemon balm or a bit of honey makes it more drinkable.
One important note: valerian interacts with a wide range of medications. Over 250 known drug interactions have been documented, including common ones like diphenhydramine (Benadryl), ibuprofen, trazodone, and aspirin. If you take any sedatives, pain relievers, or sleep medications, check for interactions before adding valerian to your routine.
Passionflower: Best for Staying Asleep
If your problem is waking up at 3 a.m. rather than falling asleep, passionflower is worth trying. It supports GABA production in the brain rather than just binding to existing receptors, which may explain why it’s particularly helpful for sleep maintenance. GABA is the neurotransmitter most responsible for keeping your nervous system calm and preventing the kind of middle-of-the-night alertness that pulls you out of deep sleep.
Steep one to two teaspoons of dried passionflower in hot water (95°C) for a full 10 minutes, covered. The flavor is mild and slightly grassy, making it easy to blend with other herbs. Clinical trials have found promising results when passionflower is combined with valerian and hops, a blend that performed well even compared to prescription sleep medication in some studies.
Lemon Balm: Calming Anxiety That Keeps You Up
Lemon balm is especially effective when anxiety is the thing standing between you and sleep. In a double-blind, placebo-controlled trial, patients who took lemon balm for seven days saw anxiety levels drop by 49% and sleep quality improve by 54% compared to baseline. The placebo group improved too, but significantly less. After the intervention, anxiety scores in the lemon balm group averaged 7.15 compared to 10.18 in the placebo group.
Lemon balm tea has a light, citrusy flavor that most people enjoy on its own. Use one to two teaspoons of dried leaf per cup, steeped for five to ten minutes. It blends well with chamomile, and that combination addresses both the anxiety and the physical restlessness that can keep you staring at the ceiling.
Lavender: Relaxation Through Scent and Taste
Lavender works partly through aromatherapy. Inhaling the steam from a lavender tea activates calming pathways before you even take a sip. As a tea, it contributes a floral, slightly sweet note that pairs well with chamomile or lemon balm.
Steep one teaspoon of dried lavender buds for five to seven minutes, but no longer. Over-steeping lavender produces a soapy, overwhelmingly perfumed taste that ruins the cup. It’s best used as part of a blend rather than on its own.
Decaf Green Tea: A Different Approach
This one is counterintuitive, but decaffeinated green tea contains L-theanine, an amino acid that increases alpha brain waves. Alpha waves are the dominant pattern in people who are relaxed or drowsy. A single serving of tea delivers 25 to 60 milligrams of L-theanine, which falls within the range (50 to 200 milligrams) shown to boost alpha wave activity in brain imaging studies. Animal research has found that L-theanine combined with GABA helped subjects fall asleep faster and sleep longer than either compound alone.
The key word here is decaffeinated. Regular green tea contains enough caffeine to counteract any relaxation benefit. Look specifically for decaf versions if you’re drinking it in the evening.
How to Get the Most From Your Bedtime Tea
Timing matters more than most people realize. Drink your tea about two hours before bed. This gives the calming compounds time to take effect while also giving your body time to process the liquid so you’re not waking up to use the bathroom. Nocturia, the need to urinate during the night, is one of the most common sleep disruptors, and a cup of tea right before bed almost guarantees it.
A few brewing principles apply across all herbal teas for sleep. First, water temperature should be around 90 to 95°C. Fully boiling water (100°C) destroys some of the volatile compounds responsible for both flavor and therapeutic effect. Let your kettle sit for 30 to 60 seconds after boiling, or use a temperature-controlled kettle. Second, always cover the cup or teapot while steeping. The medicinal compounds in these herbs are partly carried by aromatic oils that evaporate quickly when exposed to air. A simple saucer over your mug works fine.
What the Evidence Actually Shows
A 2025 scoping review of over-the-counter sleep products, including 34 trials on herbal products specifically, found that most studies showed positive effects on insomnia symptoms. Side effects across all studies were mild and temporary, with no serious adverse events reported. The review called the overall findings “promising but inconclusive,” largely because studies vary widely in dosage, preparation, and duration.
The practical takeaway: herbal teas are unlikely to replace treatment for chronic insomnia, but they’re a reasonable, low-risk option for occasional sleeplessness. The best-supported options are valerian (alone or combined with hops and passionflower), lemon balm, and chamomile. If one tea doesn’t seem to help after a week or two of consistent use, try a different herb or a blend rather than assuming herbal teas don’t work for you. Individual responses vary, and the compounds in each tea act through slightly different mechanisms.
