No single tea is proven to stop tremors, but several herbal teas contain compounds that calm the nervous system in ways that may reduce tremor severity. The most promising options work by boosting a brain chemical called GABA, which inhibits the overactive nerve signaling that drives many types of tremor. Green tea, chamomile, lemon balm, and passionflower are the strongest candidates based on current evidence.
Why GABA Matters for Tremors
Many tremors, especially essential tremor (the most common movement disorder), are linked to a breakdown in the brain’s braking system. In a healthy brain, cells in the cerebellum release GABA, a neurotransmitter that quiets nerve impulses and keeps movements smooth. When those cells degenerate or GABA levels drop, the deep cerebellar neurons lose their normal inhibition. They start firing in a rhythmic pattern that travels up through the thalamus and into the motor circuits that control your hands, head, and voice. The result is the involuntary shaking you feel.
This is the same reason alcohol temporarily reduces essential tremor in many people: it mimics GABA’s effect and binds to GABA receptors, dampening the overactive signals. Several herbal teas contain compounds that work along similar pathways, though with far gentler effects.
Green Tea and L-Theanine
Green tea is the most researched option for tremor-related benefits, largely because of an amino acid called L-theanine. This compound is structurally similar to glutamate, the brain’s main excitatory neurotransmitter. Because of that resemblance, L-theanine can partially block glutamate receptors, reducing the excess neural excitation that contributes to tremor. It also crosses the blood-brain barrier and promotes GABA production, which adds a calming layer on top of the glutamate-blocking effect.
Research has shown L-theanine improves motor behavioral abnormalities in animal models of Parkinson’s disease, increases dopamine availability, and has anti-inflammatory and antioxidant properties that may protect nerve cells over time. A typical cup of green tea contains 20 to 30 mg of L-theanine, though shade-grown varieties like matcha or gyokuro can contain significantly more.
There’s a catch, though. Green tea also contains caffeine, and caffeine can make tremors worse. A study that gave participants just 150 mg of caffeine (roughly one strong cup of coffee or two to three cups of green tea) found a measurable increase in hand tremor compared to placebo. Moderate caffeine consumers who abstained overnight actually had more tremor at baseline than minimal consumers, suggesting regular caffeine use may contribute to ongoing tremor severity. If you’re trying green tea for its L-theanine content, consider decaffeinated versions or L-theanine supplements to avoid this tradeoff.
Chamomile Tea
Chamomile contains apigenin, a flavonoid that binds directly to benzodiazepine receptors in the brain. These are the same receptors targeted by prescription anti-anxiety medications like diazepam. When apigenin activates these receptors, it enhances GABA’s calming effects, producing mild sedation and muscle relaxation. The flavonoids in chamomile also act as antispasmodic agents, meaning they help reduce involuntary muscle contractions.
Chamomile won’t produce the dramatic tremor reduction that a prescription benzodiazepine might, but it’s caffeine-free and widely tolerated. It’s a reasonable choice as an evening tea, particularly if anxiety or stress worsens your tremor, since the calming effect addresses both problems at once. Steep chamomile flowers in water just under boiling (around 190 to 200°F) for five to seven minutes to get the most apigenin into your cup.
Lemon Balm Tea
Lemon balm is rich in rosmarinic acid, a compound with multiple effects on the nervous system. In animal studies, lemon balm extract inhibits GABA transaminase, the enzyme that breaks down GABA in the brain. Blocking this enzyme means more GABA stays active for longer, strengthening the brain’s natural tremor-suppressing mechanism. Lemon balm also appears to stimulate acetylcholine receptors, which play a role in fine motor control and muscle coordination.
Beyond these direct effects, rosmarinic acid has demonstrated neuroprotective properties, helping shield nerve cells from inflammation and oxidative stress. This is particularly relevant if your tremor is related to a neurodegenerative condition. Aqueous extracts of lemon balm (essentially what you get when you make tea) contain meaningful amounts of rosmarinic acid, around 245 micromoles per liter in lab preparations. A standard tea won’t match those concentrations exactly, but a strong brew using fresh or high-quality dried leaves is a reasonable way to get some benefit.
Passionflower and Skullcap
These two herbs show up frequently in traditional formulas for nervous system conditions, and both have some modern evidence behind them. Passionflower contains compounds that increase GABA levels in the brain, and it has a long history of use for anxiety, insomnia, and nervous restlessness. Skullcap (specifically American skullcap) has demonstrated anticonvulsant effects in animal studies, meaning it reduces the kind of abnormal, repetitive nerve firing that underlies both seizures and tremors. Test-tube research also suggests skullcap may have neuroprotective properties relevant to Parkinson’s and Alzheimer’s disease.
The limitation with both herbs is that human clinical trials are scarce. Most evidence comes from animal or laboratory studies, so it’s difficult to say how much tremor reduction you’d realistically notice from a cup of passionflower or skullcap tea. Still, both are caffeine-free and generally well tolerated, making them low-risk options to try alongside better-studied approaches.
Magnesium-Rich Herbal Infusions
Magnesium plays a direct role in muscle relaxation and nerve signal transmission. Low magnesium levels can cause muscle twitching, cramping, and increased tremor severity. While most people think of supplements when they think of magnesium, certain herbal infusions can deliver meaningful amounts. Nettle, alfalfa, red clover, and horsetail are all high in magnesium when brewed as strong infusions. The key is using about one ounce of dried herb per 32 ounces of water and steeping for an extended period, closer to 15 to 20 minutes, since mineral extraction takes longer than pulling out delicate flavor compounds.
These won’t taste like a typical tea. They’re more like a mild, earthy broth. But if you’re looking for a dietary way to support your magnesium intake alongside other tremor-reducing teas, they’re worth considering.
Teas and Drinks to Avoid
Caffeine is the biggest concern. Even 150 mg, roughly the amount in a large cup of black tea or a small coffee, has been shown to increase measurable hand tremor in controlled studies. At doses above 400 mg, the effects become more pronounced, with increased anxiety and jitteriness that can amplify tremor further. Black tea, yerba mate, and heavily caffeinated green teas are the main culprits. If you’re sensitive, you may notice worse tremors within 30 to 60 minutes of drinking them.
Ginseng tea is another one to approach carefully. It has been associated with tremor as a side effect, particularly in combination with certain medications like calcium channel blockers.
Preparation Tips for Maximum Benefit
How you brew your tea matters. For leaf and flower teas like chamomile, lemon balm, green tea, passionflower, and skullcap, use water just below boiling (190 to 200°F) and steep for three to seven minutes. Taste at three minutes and continue steeping if you want a stronger brew. For root-based preparations or mineral-rich infusions like nettle, use fully boiling water and steep for 10 to 20 minutes to extract the tougher compounds.
Loose-leaf preparations are generally more potent than tea bags because the larger leaf pieces retain more of their active compounds. If you’re combining herbs, a blend of chamomile and lemon balm makes a good starting point: both are caffeine-free, pleasant-tasting, and work through complementary mechanisms (apigenin targeting benzodiazepine receptors while rosmarinic acid preserves GABA levels).
A Note on Medication Interactions
If you take medication for tremor or seizures, be aware that some herbal teas can interact with those drugs. Green tea has documented interactions with anti-seizure medications, which include primidone, one of the most commonly prescribed drugs for essential tremor. Lavender also interacts with anti-seizure drugs. Black cohosh carries cautions for people with epilepsy or those on blood pressure medications. These interactions can either amplify or reduce the effectiveness of your medication, so it’s worth discussing any new herbal tea habit with whoever manages your prescriptions.
