What lemon balm tea is and what research shows it may do
Lemon balm tea is brewed from the dried or fresh leaves of the lemon balm plant, a mint-family herb with a mild lemon scent. People drink it mainly for three reasons: to feel calmer, to sleep better, and to ease mild digestive discomfort. The plant contains compounds called terpenes and phenolic acids that appear to affect how your nervous system works, though the research on humans is still small and mixed.
Most studies on lemon balm have been done in labs or on animals, or involved very small groups of people. What that means in plain terms: we know the herb contains active compounds, we have some evidence those compounds do something in the body, but we do not yet have large, rigorous human trials that prove drinking the tea will definitely calm you down or help you sleep. People report it helps, and some research suggests it might, but "might help" is different from "will help."
Key Takeaways
- Lemon balm tea may help reduce anxiety and promote relaxation, though human research is limited and results vary by person.
- Some people find it helps them fall asleep or sleep more deeply, but it is not a sedative and does not work the same way prescription sleep aids do.
- The herb may ease mild stomach upset, bloating, or cramping, particularly when combined with other digestive herbs.
- Lemon balm is generally considered safe for most adults, but it can interact with certain medications and is not recommended during pregnancy.
How lemon balm may affect anxiety and stress
The most common reason people drink lemon balm tea is to feel less anxious or stressed. Several small human studies have found that people who took lemon balm extract or drank the tea reported feeling calmer, and their stress markers (like cortisol levels) sometimes dropped. One study of people with mild anxiety found that those given lemon balm showed more improvement than those given a placebo, though the group was small.
The mechanism appears to involve how lemon balm interacts with GABA, a neurotransmitter that helps your nervous system wind down. However, the effect is gentle—lemon balm is not a tranquilizer and will not make you drowsy or impaired. If you are taking prescription anxiety medication, lemon balm tea is not a replacement, and you should talk to your doctor before adding it to your routine.
What the research says about sleep
People often drink lemon balm tea in the evening hoping it will help them fall asleep or stay asleep. Some research supports this: a few small studies found that people who took lemon balm reported falling asleep faster or sleeping more soundly. One study combined lemon balm with valerian root and found the combination helped people with insomnia sleep better than a placebo.
The catch is that lemon balm itself is not a strong sedative. It does not contain compounds that force sleep the way prescription sleep medications do. Instead, it may help by reducing the anxiety or racing thoughts that keep you awake. If you have chronic insomnia, lemon balm tea alone is unlikely to be enough—but it may be a useful part of a broader sleep routine that includes consistent bedtime, a cool dark room, and limiting screens before bed.
Digestive benefits and how they work
Lemon balm has been used in traditional medicine for stomach problems for centuries, and some modern research backs this up. Studies suggest the herb may reduce bloating, cramping, and mild indigestion, particularly in people with irritable bowel syndrome. One study found that people with IBS who took lemon balm extract reported less abdominal pain and bloating than those who took a placebo.
The plant appears to work by relaxing the smooth muscles in your digestive tract and reducing gas production. It may also have mild antimicrobial properties. That said, if you have a serious digestive condition or chronic stomach pain, lemon balm tea is not a treatment—it is a beverage that may ease mild symptoms while you address the underlying cause with a doctor.
How to brew and drink lemon balm tea
You can buy lemon balm tea as dried leaves (loose or in bags) at most grocery stores, health food stores, or online. To brew it, steep one teaspoon of dried leaves or a small handful of fresh leaves in eight ounces of hot water for five to ten minutes, then strain. The longer you steep, the stronger the flavor and the higher the concentration of active compounds.
Most people drink one to three cups per day. There is no official recommended dose, so start with one cup and see how you feel. You can drink it hot or let it cool and drink it cold. Some people add honey or a squeeze of lemon juice for flavor. If you are using lemon balm for sleep, drinking a cup thirty minutes to an hour before bed is a common approach, though the timing varies by person.
Who should avoid lemon balm tea or talk to a doctor first
Lemon balm is generally safe for most adults and has few reported side effects. However, certain groups should be cautious. If you are pregnant or breastfeeding, avoid lemon balm tea—there is not enough research to confirm it is safe in these situations. If you have thyroid disease, particularly Graves' disease, talk to your doctor before drinking lemon balm regularly, as some research suggests it may affect thyroid function.
Lemon balm can interact with sedative medications, blood thinners, and some diabetes medications. If you take any prescription drugs, mention lemon balm to your doctor or pharmacist before making it a regular habit. Some people report mild side effects like nausea or dizziness, though these are uncommon. If you are allergic to mint-family plants, you may react to lemon balm.
Lemon balm tea versus other calming herbs
Lemon balm is one of several herbs people use to manage stress and sleep. Chamomile is more widely studied for sleep and is often considered stronger. Passionflower and valerian root are also popular for anxiety and sleep, though valerian has a stronger, less pleasant taste. Lavender is used mainly for relaxation and has a distinct flavor.
The choice often comes down to personal preference and how your body responds. Some people find lemon balm works better than chamomile; others prefer chamomile. Many people combine lemon balm with other herbs—for example, lemon balm and chamomile together, or lemon balm and valerian for sleep. There is no single "best" herb; what matters is what works for you and whether it fits safely into your life.
Frequently Asked Questions
Does lemon balm tea have caffeine?
No. Lemon balm is an herb, not a tea plant, so it contains no caffeine. You can drink it any time of day without worrying about it keeping you awake. This also means it will not give you an energy boost the way green or black tea does.
How long does it take to feel the effects?
This varies widely. Some people report feeling calmer within thirty minutes of drinking a cup. Others notice a difference only after drinking it regularly for a few days or weeks. If you are trying it for sleep, give it at least a week of consistent use before deciding whether it works for you.
Can I drink lemon balm tea every day?
Yes, lemon balm is safe for daily use in most adults. However, if you are taking medications or have a health condition, check with your doctor first. Some people find that drinking it every day works better than occasional use, while others prefer to drink it only when they feel stressed or before bed.
Is fresh lemon balm better than dried?
Both work. Fresh lemon balm has a brighter flavor and may contain slightly higher levels of some compounds, but dried lemon balm is more convenient and keeps longer. If you have access to fresh lemon balm from a garden or farmers market, try it; otherwise, dried is a reliable option.
What should I do if lemon balm tea does not help me?
Not every herb works for every person. If you have tried lemon balm regularly for two to three weeks and notice no change, it may straightforward not be effective for you. You can try a different herb, combine it with other approaches like exercise or meditation, or talk to a doctor if anxiety or sleep problems are affecting your life.
