Linden tea has been valued for its potent sedative properties for hundreds of years (1).
It’s derived from the Tilia genus of trees, which typically grows in temperate regions of North America, Europe, and Asia. Tilia cordata, also known as small-leaved lime, is considered the most potent species of the Tilia genus (1).
Linden tea has been used in folk medicine across cultures to relieve high blood pressure, calm anxiety, and soothe digestion.
To create this herbal infusion, flowers, leaves, and bark are boiled and steeped. Separately, these components have been used for different medicinal purposes (1).
Here are 8 surprising benefits of linden tea.
Sitting down to enjoy a warm cup of tea can be a comforting ritual on its own.
Although, linden tea goes beyond the comforts of an everyday mug of tea.
One mouse study found that extracts from the buds of Tilia tomentosa, a kind of linden tree, had strong sedative properties (
Researchers concluded that this linden extract mimicked the activity of gaba-aminobutyric acid (GABA), a brain chemical that inhibits excitability in the human nervous system (
Summary Linden tea may promote relaxation by inhibiting your ability to become excited. However, human research on this effect is lacking.
Chronic inflammation can contribute to the development of many conditions, including type 2 diabetes and cancer (
Antioxidants are compounds that help fight inflammation, potentially lowering your risk of disease. Flavonoids are a type of antioxidant in Tilia flowers, whereas tiliroside, quercetin, and kaempferol are specifically associated with linden buds (1,
Kaempherol may fight inflammation as well. Plus, some studies show that it may provide cancer-fighting properties (
As the amount of these antioxidants may vary by brand and tea blend, more research is needed to determine how much linden tea you would need to drink to reduce inflammation.
Summary Linden tea contains powerful antioxidants like tiliroside and kaempferol that help fight inflammation. Chronic inflammation is associated with many diseases, including diabetes and cancer.
One study found giving 45.5 mg of tiliroside per pound (100 mg per kg) of body weight to mice with swollen paws reduced swelling and pain by nearly 27% and 31%, respectively (6).
Another 8-week study in 50 women with rheumatoid arthritis, which is characterized by painful and stiff joints, found that supplementing with 500 mg of quercetin, an antioxidant in linden tea, significantly improved pain symptoms and markers of inflammation (
However, keep in mind that 500 mg of quercetin is a lot. Adults in the United States consume 10 mg of this antioxidant daily, on average, though this number varies greatly depending on your diet, with 80 mg per day being considered a high intake (
The amount of quercetin or other flavonoids in linden tea differs greatly depending on the brand and the proportions of buds, leaves, and bark in a particular blend.
As a result, it’s impossible to know how much of these antioxidants you may be getting in a single cup of tea. Additional research is needed to determine how much of this beverage is needed to relieve pain.
Summary Tiliroside and quercetin — two antioxidants in linden tea — may help reduce pain. Still, more research is needed to determine how much of the tea you would need to drink to reap this potential benefit and whether the amount would be safe.
The inner bark of the Tilia tree has been associated with diuretic and diaphoretic effects. A diuretic is a substance that encourages your body to excrete more fluid, while a diaphoretic is a substance that’s used to cool a fever by encouraging sweat (
Linden tea has been used in folk medicine to promote sweating and productive coughs when a minor illness like a cold takes hold (1).
In Germany, 1–2 cups (235–470 ml) of linden tea at bedtime is approved for use as a sweat-promoting infusion in adults and children over 12 years old (1).
These effects may be caused by the combination of its plant compounds, specifically quercetin, kaempferol, and p-coumaric acid. At this time, scientific evidence directly linking linden tea and its chemical properties to diuretic effects is insufficient (1).
The bulk of the available data regarding this association is anecdotal, though it spans back to the Middle Ages. Thus, this purported health benefit warrants further investigation (1).
Summary Linden tea has been used in folk medicine to promote sweating and is thought to be a diuretic. However, scientific research to explore these claimed effects is warranted.
Mice were injected with doses of 0.45, 2.3, and 4.5 mg of the antioxidant per pound (1, 5, and 10 mg per kg) of body weight. As a response, systolic blood pressure (the top number of a reading) decreased (6,
This may help explain why linden tea has been used to reduce blood pressure in folk medicine.
Yet, this effect is not yet fully understood and needs further scientific investigation. Linden tea should never be used to replace heart medications.
Summary Folk medicine has used linden tea to lower blood pressure. The mechanism behind this effect is unknown and needs to be studied further.
Sleep quality and duration significantly affect your health.
Still, more research is needed to explore the relationship between linden tea and sleep.
Summary Linden tea promotes sleep, but how it exerts this effect is limited to anecdotal evidence. More research is needed to understand the relationship.
Like any hot tea, linden tea delivers gentle heat and hydration. Both soothe your digestive tract, as water can help food move through your intestines. Folk medicine touts the use of linden tea in times of stomach discomfort.
In one small study in children with antibiotic-resistant diarrhea, tiliroside showed potent antibacterial properties. While this antioxidant was extracted from a different flower, it’s found in linden tea as well (
That said, no evidence directly links the compounds in linden tea to an ability to soothe an irritated digestive tract.
Summary In times of gastric distress, linden tea may soothe your digestive system. Tiliroside, one of its plant compounds, has been shown to help fight infectious diarrhea. Still, more research is needed on linden tea specifically.
Adding linden tea to your diet is easy. Given that it can promote relaxation and sleep, it may be a good idea to drink a cup before bedtime. You can enjoy on its own or with a wedge of lemon and dollop of honey.
You can even steep a few bags of linden tea overnight in room-temperature water and drink it as iced tea in the summertime.
If possible, it’s a good idea to steep your tea leaves without a filter bag. Studies have found that this helps retain more of their antioxidants (
Summary Adding linden tea to your diet can be as simple as brewing a good warm mug of it. To get the most antioxidants out of your tea, steep your tea loose without filtered bags.
The European Medicines Agency finds that moderate intake, which is defined as 2–4 grams of the tea blend per day, is safe. However, you should not drink the tea in excess (1).
A typical 8-ounce (235-ml) mug of linden tea contains about 1.5 grams of loose tea. Still, there is some variability in how much you may ingest after it infuses hot water. It’s a good idea to limit your intake to no more than 3 cups a day, as needed (1).
Though it is generally considered safe, avoid linden tea if you’re allergic to linden or its pollen.
Safety in children and pregnant or nursing women
The safety of linden tea in pregnant or nursing women is unknown. Therefore, it’s not recommended to drink this tea under these circumstances.
It has not been tested in children either, so it’s not recommended for regular use in this population.
Long-term use is linked to heart disease
Linden tea and other products derived from the Tilia tree family should not be used by those with a history of heart conditions.
For this reason, it’s best to drink it in moderation. Those with heart disease or other heart issues should talk to their healthcare provider before regularly consuming this tea (
Can interact with certain medications
People who take medications containing lithium should not drink linden tea, as the beverage can change how your body excretes this element. This can affect dosing and may have serious side effects (21).
Summary While linden tea may offer many health benefits, frequent, long-term use may cause heart damage. It should not be used by children or people who have heart problems, take certain medications, or are pregnant or nursing.
Linden tea comes from the Tilia tree and has been used in folk medicine for hundreds of years.
Though its flowers are most prized, the bark and leaves can also be steeped to produce a delicious and fragrant beverage.
Drinking linden tea may promote relaxation, help fight inflammation, alleviate pain, and soothe your digestive tract.
However, people taking certain medications, those with heart problems, and pregnant or nursing women should avoid it. It’s best to drink this tea in moderation and not every day.
Adding linden tea to your diet is easy. To get the most out of your cup, be sure to brew linden as a loose-leaf tea.
If you can’t find linden tea locally, you can purchase both tea bags and loose leaves online.
