Several herbal teas have evidence supporting their use for heart palpitations, with chamomile, lemon balm, hawthorn berry, and motherwort among the most studied. The best choice depends on what’s triggering your palpitations. Stress and anxiety cause a large share of benign palpitations, so teas with calming properties often help the most. But some true teas (black, green, white) contain caffeine, which can make palpitations worse in sensitive people.
Lemon Balm Tea for Stress-Related Palpitations
If your heart races or flutters when you’re anxious, lemon balm is one of the strongest options. A study of older adults with cardiac problems found that lemon balm inhalation reduced transient anxiety scores within minutes compared to a control group. The researchers also observed measurable drops in mean arterial pressure, supporting the idea that lemon balm has genuine anti-stress effects on the cardiovascular system, not just a placebo calming sensation.
Lemon balm tea is caffeine-free, widely available, and has a mild, slightly citrusy flavor that makes it easy to drink regularly. It works well as an evening tea, since its relaxing properties can also support sleep. Poor sleep is one of the most commonly self-reported triggers for atrial fibrillation, so this dual benefit matters.
Hawthorn Berry Tea for Heart Rhythm
Hawthorn berry has the most direct relationship with heart rhythm of any herbal tea. Research on hawthorn extracts shows they have both antiarrhythmic effects (helping stabilize irregular rhythms) and negative chronotropic effects, meaning they gently slow heart rate. Unlike beta-blocker medications, hawthorn appears to work through a different mechanism: it relaxes blood vessels by stimulating nitric oxide production and exerts a tonic effect directly on heart muscle cells.
Hawthorn also provides significant antioxidant activity, which protects the cardiovascular system over time. It has a long history of traditional use for strengthening the heart, and modern pharmacological research supports those claims. Hawthorn berry tea has a tart, slightly sweet flavor and is typically made from dried berries steeped for 10 to 15 minutes.
One important caveat: if you take any heart medications, particularly beta-blockers or blood pressure drugs, talk to your pharmacist before adding hawthorn to your routine. Herbal products with cardiovascular effects can alter how your medications work.
Motherwort Tea for Irregular Heartbeats
Motherwort (its Latin name, Leonurus cardiaca, literally translates to “lion heart”) has been used for centuries specifically for heart complaints. Modern research explains why. Motherwort extract acts on multiple cardiac ion channels simultaneously: it blocks a type of calcium current involved in heart contraction, modifies the “funny current” that controls your heart’s natural pacemaker cells, and antagonizes a potassium current linked to arrhythmias. This combination of effects gives it both antiarrhythmic and antianginal properties.
Motherwort tea is brewed from the aerial parts of the plant and has a notably bitter taste. Many people blend it with honey or mix it with a milder herb like lemon balm to make it more palatable. It’s traditionally taken in small amounts rather than large cups.
Green Tea: Protective in Small Amounts
Green tea occupies an unusual position on this list because it contains caffeine (30 to 50 mg per cup), yet research suggests low-dose consumption actually protects against palpitations. A large population study found that low-dose green tea intake strongly reduced the incidence of atrial fibrillation, including both the occasional (paroxysmal) and ongoing (persistent) types.
The protective effect comes primarily from a powerful antioxidant compound in green tea that reduces inflammation, oxidative stress, and the structural remodeling of heart tissue that leads to rhythm problems. Palpitations linked to atrial fibrillation involve a cascade of inflammation and electrical changes in the heart’s upper chambers, and this compound appears to interrupt that process at multiple points.
The key word is “low-dose.” One to two cups daily appears beneficial. Drinking large quantities of green tea could introduce enough caffeine to trigger palpitations in sensitive individuals, especially if combined with other caffeine sources. If you notice your heart fluttering after green tea, switch to a caffeine-free option instead.
Passionflower Tea for Anxiety Before Events
Passionflower has traditionally been used as a sedative, and limited research suggests it can reduce anxiety symptoms, including the kind of anticipatory anxiety that often triggers palpitations before stressful events like medical procedures or public speaking. The National Institutes of Health notes that small studies support its use for general anxiety and pre-surgical nervousness, though the evidence isn’t yet definitive.
Passionflower tea is caffeine-free and has a mild, grassy flavor. It can cause drowsiness, dizziness, or confusion in some people, so it’s best tried at home before you rely on it in a situation where you need to be alert.
Teas to Approach With Caution
Not all teas are helpful for palpitations. Caffeine is one of the most commonly reported triggers for symptomatic atrial fibrillation, alongside alcohol, exercise, and poor sleep. While moderate caffeine intake (roughly 200 to 300 mg per day, or about two to three cups of coffee) doesn’t appear to cause palpitations in most people, individual sensitivity varies widely.
If you’re caffeine-sensitive, keep these ranges in mind when choosing a tea:
- Black tea: 40 to 60 mg per cup
- Green tea: 30 to 50 mg per cup
- White tea: 25 to 40 mg per cup
White tea has the least caffeine of the three, but none of these are caffeine-free. If caffeine triggers your palpitations, stick entirely with herbal teas like lemon balm, hawthorn, chamomile, or motherwort, which contain no caffeine at all.
Also be cautious with ginseng tea, which can interact with diuretics and beta-blockers, and ginger tea, which may increase bleeding risk if you take blood thinners. Green tea can reduce the effectiveness of certain beta-blockers, particularly nadolol. These interactions don’t mean you can never drink these teas, but they’re worth discussing with your pharmacist if you take cardiac medications.
Making Tea Part of a Palpitation Strategy
Tea works best as one piece of a broader approach. Since palpitations often cluster around the same triggers in individual people, keeping a simple log of when they happen can help you identify your personal pattern. Common triggers include caffeine, alcohol, dehydration, poor sleep, and stress. Once you know your triggers, you can choose the tea that matches: lemon balm or passionflower for anxiety-driven episodes, hawthorn or motherwort for more rhythm-focused support, and green tea in moderation for long-term cardiovascular protection.
Brewing matters for potency. Most herbal teas release their active compounds best with boiling water and a steep time of at least 5 to 10 minutes, covered, so the volatile oils don’t escape with the steam. Pre-bagged herbal teas from grocery stores contain less plant material than loose-leaf versions, so if you’re drinking tea specifically for its heart-calming effects, loose-leaf or bulk dried herbs typically deliver a stronger result.
Palpitations that come with chest pain or pressure, fainting, trouble breathing, or unusual sweating are a different situation entirely. Those symptoms point to something more serious than what any tea can address and need prompt medical evaluation.
