Struggling to fall asleep or stay asleep is one of the most common complaints adults share. Many people turn to caffeine-free herbal teas not just for flavor, but for their calming effects.
Unlike traditional tea from Camellia sinensis, herbal teas (tisanes) are caffeine-free infusions of herbs, flowers, roots, or leaves that have been used across cultures to support relaxation and sleep. While no tea is a cure for insomnia, research suggests that certain herbs contain plant compounds that interact with the nervous system and may support a more restful night.
This guide explains how herbal teas can support sleep, highlights the most studied options, and shares simple ways to incorporate them into your nightly routine.
What Is the Best Herbal Tea for Sleep?
The most studied herbal teas for sleep include:
- Chamomile
- Valerian root
- Lavender
- Lemon balm
- Passionflower
Each contains plant compounds associated with relaxation and calming nervous system activity. The best choice often depends on individual response, which is why trying different herbs can be helpful.
1. What Are Herbal Teas?
Herbal teas (tisanes) are just teas made from plant materials such as flowers, leaves, roots, or seeds (rather than camellia sinensis).
Because they don’t come from the Camellia sinensis plant, herbal teas do not contain caffeine or L-theanine the way green or black teas do. Instead, many herbs contain flavonoids, volatile oils, or other compounds linked to relaxation and mild calming effects.
2. How Herbal Teas Influence Sleep
Certain herbal teas contain compounds that affect the nervous system:
Apigenin in chamomile binds to GABA receptors in the brain, which may reduce anxiety and support sleep initiation. A 2016 randomized trial published in Journal of Advanced Nursing found that chamomile extract improved sleep quality in adults experiencing sleep disturbance.
Valerenic acid in valerian root appears to interact with GABA and other neurotransmitter systems involved in sleep regulation. Reviews published in Sleep Medicine Reviews have reported reductions in sleep latency (the time it takes to fall asleep) in some participants.
Lavender’s volatile oils have been associated with improved sleep quality and reduced anxiety in adults reporting insomnia symptoms, according to studies published in Evidence-Based Complementary and Alternative Medicine.
While results vary by individual and preparation strength, these mechanisms are among the most studied for herbal sleep support.

Chamomile
Chamomile is one of the most studied herbal teas for nighttime relaxation. The flavonoid apigenin may engage calming pathways without causing heavy sedation.
Valerian Root
Valerian has a long research history showing reduced time to fall asleep and improved subjective sleep quality in adults. It is often brewed as a stronger infusion or blended with other calming herbs.

Lemon Balm & Passionflower
These herbs are often used together. Lemon balm supports stress relief, while passionflower may enhance GABA activity in the brain.
Not every herb works the same for every person. Some people respond best to chamomile, while others find valerian or lavender more effective. Trying a small sleep-focused herbal sampler can be an easy way to discover what works best for you.
4. How to Prepare Herbal Teas for Sleep
Preparation matters. To maximize potential calming compounds:
- Use near-boiling water (about 200–212°F) for most herbal teas.
- Steep longer than usual. While a 5-minute steep extracts flavor, steeping for 7–12 minutes allows more of the plant compounds to infuse into the water.
- Cover your cup while steeping to help retain volatile oils.
Consistency is important. Brewing the same tea each evening can become part of a calming bedtime signal for your body.
5. When to Drink Herbal Teas for Optimal Sleep
For most people, drinking herbal tea 30–60 minutes before bedtime allows enough time for relaxation to set in.
Pairing tea with a calming activity — such as reading, journaling, or gentle stretching — reinforces the signal that it’s time to wind down.
Herbal teas work best as part of a broader sleep routine that includes consistent bedtimes and reduced evening screen exposure.
6. Who Should Use Caution
Herbal teas are generally well tolerated, but certain individuals should consult a healthcare professional before use:
- Those taking sedatives or anti-anxiety medications
- Individuals on sleep medications
- Pregnant or breastfeeding individuals
- Anyone with known plant allergies
Starting with one cup to assess sensitivity is a sensible approach.
