6 Best Herbal Teas for Sleep

There's a reason a warm cup of herbal tea feels so soothing at the end of a long day — and for better sleep and a calmer mind, some brews are especially worth reaching for.
The comfort in a cup
A cup of delicious, aromatic herbal tea can genuinely soothe the soul. A prominent part of many cultures for centuries, herbal teas (technically "tisanes", since they contain no actual tea leaf) offer benefits for digestion, stress and relaxation — and, for many people, better sleep. Part of their magic is the ritual itself: pausing, warming your hands around a cup, and signalling to your body that the day is winding down. But beyond the comforting routine, several herbs contain compounds with genuinely calming, sleep-supporting properties. If you struggle to switch off at night, a well-chosen herbal tea can be a lovely, gentle addition to your bedtime routine. Here are six of the best, along with an honest look at what the evidence says.
Chamomile and valerian: the classics
Chamomile tea for sleep is where most people start, and no list of bedtime brews would be complete without it — it is among the most popular and the most widely studied.
A randomised, placebo-controlled pilot study of chamomile extract in adults with chronic insomnia found modest, mostly small-to-moderate effects — with favourable trends for sleep latency, night-time awakenings and daytime functioning — and confirmed that chamomile was well tolerated (chamomile insomnia pilot study).
Chamomile's calming reputation is linked to a flavonoid called apigenin, which is thought to interact with the same GABA receptors in the brain targeted by many calming medications. Valerian is the other great classic — the most-studied of all the sleep herbs, with a long history of use for insomnia.
A large randomised, placebo-controlled trial of valerian for insomnia concluded that valerian appears safe, with modest beneficial effects at most on sleep compared with placebo, and that its benefits tend to build with consistent use rather than working instantly (valerian insomnia trial).
Four more calming brews
Beyond the two classics, several other herbal teas are traditionally cherished for winding down. Lavender tea, with its distinctive floral aroma, is widely used to ease anxiety and promote relaxation before bed — and even its scent is calming. Passionflower has a long traditional use for restlessness and sleeplessness, and is thought, like chamomile, to gently support GABA activity in the brain. Lemon balm, a member of the mint family with a soft citrus note, is prized for easing stress and is often blended with valerian for a synergistic calming effect. And ashwagandha, the celebrated Ayurvedic adaptogen, can be enjoyed as a warming bedtime drink to help ease the stress and elevated cortisol that so often keep us wired at night — a herb we explore in herbs for stress and anxiety. Each has its own character, so it's worth experimenting to find the flavour and effect that suit you.
Why a warm brew helps you wind down
It's worth understanding why herbal teas earn their place in a bedtime routine, because the benefit comes from more than the herbs alone. Part of it is behavioural: making and sipping a warm, caffeine-free drink is a gentle ritual that tells your body the day is ending, and consistent pre-sleep cues like this are one of the genuine pillars of good sleep hygiene. Part of it is physiological: a warm drink can be comforting and relaxing, and the simple act of slowing down — away from screens, work and worry — lowers the mental arousal that so often keeps us awake. And part of it, of course, comes from the calming plant compounds themselves, several of which appear to interact gently with the brain's own relaxation systems. Crucially, herbal teas are naturally free of caffeine, which makes them a far better evening choice than ordinary tea or coffee, whose caffeine can linger in the body for many hours and sabotage sleep without you realising. This combination — a soothing ritual, a warm caffeine-free drink, and mildly calming herbs — is why a bedtime brew can be such a pleasant and useful part of winding down, even if no single herb is a powerful sedative on its own. Thinking of it this way also sets sensible expectations: you're building a calming habit, not taking a sleeping pill, and habits are exactly what good sleep is built on.
Getting the most from your bedtime brew
To make the most of a sleep tea, a little know-how helps. Brew it 30 to 45 minutes before bed, using hot (not boiling) water, and steep for a good 5 to 10 minutes to draw out the beneficial compounds. Make it part of a consistent wind-down ritual — dimming the lights, putting screens away — since the routine amplifies the effect, and the screen point matters more than most people realise, as we discuss in how your phone affects your sleep. Be honest with your expectations, too: the evidence for sleep teas is real but modest, and they work best as a gentle nudge and a calming cue rather than a knockout sedative. For those who'd like some extra calming support alongside their tea, our Liposomal GABA + Ashwagandha capsules combine two soothing ingredients in a well-absorbed form. A quick word of caution: if you're pregnant, breastfeeding, or on medication, check which herbs are suitable, as some (like valerian) can interact with sedatives. And most importantly, if you have persistent insomnia, don't just mask it — ongoing sleep problems deserve proper attention, so speak to a doctor, since there may be an underlying cause worth addressing.
Frequently asked questions
What is the best herbal tea for sleep?
Chamomile and valerian are the two best-known and best-studied, with modest evidence for supporting sleep. Lavender, passionflower, lemon balm and ashwagandha are also popular calming options. The best tea for sleep is partly a personal matter, so it's worth experimenting to find the flavour and effect that suit you.
Does chamomile tea actually help you sleep?
Chamomile is calming and well tolerated, with its effects linked to apigenin acting on GABA receptors. Studies show modest benefits — more of a gentle wind-down cue than a strong sedative. It works best as part of a consistent, relaxing bedtime routine rather than a guaranteed sleep aid.
How should I brew tea for sleep?
Brew it 30 to 45 minutes before bed with hot (not boiling) water, and steep for 5 to 10 minutes to draw out the beneficial compounds. Make it part of a calming wind-down ritual — dimming lights and putting screens away — which amplifies the relaxing effect.
Are herbal sleep teas safe?
For most people, yes, in normal amounts. But if you're pregnant, breastfeeding or on medication, check which herbs are suitable, as some (like valerian) can interact with sedatives. Introduce one herb at a time so you can tell how you respond, and watch for any allergies.
How quickly do sleep teas work?
The calming ritual can help the same evening, but the herbal effects are generally gentle and modest. Some herbs, like valerian, tend to work better with consistent use over days or weeks rather than instantly. Think of sleep teas as a soothing nudge, not a knockout pill.
When should I see a doctor about my sleep?
If insomnia is persistent or affecting your daily life, see a doctor rather than just masking it with teas. Ongoing sleep problems can have underlying causes — from stress and anxiety to medical conditions — that deserve proper assessment and treatment.
