This tree grows in the northern, temperate climates of Europe, Asia, and North America. Many medicinal species of linden exist, with Tilia cordata and Tilia platyphyllos generally being the most available and studied. Regardless of species, the flowers are used as medicine. Though sometimes called lime flower, linden is not related to the familiar green lime fruit.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.
3 Stars Reliable and relatively consistent scientific data showing a substantial health benefit.
2 Stars Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
1 Star For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Indigestion, Heartburn, and Low Stomach Acidity
Several cups of tea per day, made with 2 to 3 tsp of dried flowers per cup of hot water, for indigestion
Linden has a long tradition of use for indigestion. It has antispasmodic action and may help people who suffer from upset stomach or excessive gas.
Carminatives (also called aromatic digestive tonics or aromatic bitters) may be used to relieve symptoms of indigestion, particularly when there is excessive gas. It is believed that carminative agents work, at least in part, by relieving spasms in the intestinal tract.3
Linden has a long tradition of use for indigestion. Older clinical trials have shown that linden flower tea can help people who suffer from upset stomach or from excessive gas that causes the stomach to push up and put pressure on the heart (also known as the gastrocardiac syndrome.)4 , 5 The reputed antispasmodic action of linden, particularly in the intestines, has been confirmed in at least one human trial.6 Linden tea is prepared by steeping 2–3 tsp of flowers in a cup of hot water for 15 minutes. Several cups per day are recommended.

Linden is one of a group of “nerve tonic” (nervine) herbs used in traditional herbal medicine for people with anxiety, with few reports of toxicity.
Common Cold and Sore Throat
Refer to label instructions
Linden may promote a healthy fever and the immune system’s ability to fight infections.
Boneset is another immune stimulant and diaphoretic that helps fight off minor viral infections, such as the common cold. In addition, linden and hyssop may promote a healthy fever and the immune system’s ability to fight infections. Yarrow is another diaphoretic that has been used for relief of sore throats, though it has not yet been researched for this purpose.

An unpublished clinical trial found that linden tea was effective at speeding recovery and reducing complications such as ear infection in children with colds.
An unpublished clinical trial of children with colds found that linden tea, aspirin, and bed rest were more effective than antibiotics at speeding recovery and reducing complications such as ear infection.7 (Aspirin is no longer given to children due to the threat of Reye’s syndrome.) However, no research has yet confirmed the use of linden for preventing ear infections.
The major active constituents in linden are flavonoids, glycosides, and possibly a volatile oil. One study found that a complex mixture of compounds, primarily flavonoids, reduced anxiety in mice.8 Although used as a traditional herbal remedy for anxiety, these results have not been confirmed in human clinical trials. Older clinical trials have shown that linden flower tea can help people with mild gallbladder problems (but not gallstones), upset stomach or dyspepsia, and excessive gas that causes the stomach to push up and put pressure on the heart (also known as the gastrocardiac syndrome.)9 , 10 Linden’s reputed antispasmodic action, particularly in the intestines, has been confirmed in at least one human trial.11
Linden flowers act as a diaphoretic when consumed as a hot tea. Diaphoretics induce a mild fever, thereby possibly helping promote the immune system’s ability to fight infections. The fever usually does not go very high because the diaphoretic also causes sweating, the body’s natural way of lowering its temperature. The German Commission E has approved linden flower for the treatment of colds and cold-related coughs.12
A tea of linden is prepared by adding 2–3 teaspoons (5–10 grams) of dried or fresh flowers to a pint (500 ml) of just boiled water. After steeping the flowers in a covered container for ten to fifteen minutes, sip the tea while it is still hot. During an acute problem, several cups can be taken daily for up to one week.13 For longer term use (three to six months), three cups (750 ml) per day can be used. A tincture or fluid extract of linden, 3/4–1 teaspoon (3–5 ml) three times daily, may alternatively be used.
Statements that overuse of linden can cause heart problems14 lack scientific merit. Both the German Commission E monograph and the American Herbal Products Association’s guide on herbal safety state that linden has no toxic effects.15 , 16 In fact, linden is considered safe for use in children17 and there are no known reasons to avoid it during pregnancy and breast-feeding.
