Parts used and where grown
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.
Linden has been used in
connection with the following conditions (refer to the individual
health concern for complete information):
Historical or traditional use (may
or may not be supported by scientific studies)
Since time immemorial, the fragrant and tasty linden flowers have been used medicinally as
a calming agent and to relieve indigestion,
the common cold, and griping or colicky pain
in the abdomen.1 2 Many of these uses have been confirmed or partially
confirmed in modern research.
Active constituents
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.3 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.)4 5 Linden’s reputed antispasmodic
action, particularly in the intestines, has been confirmed in at least one human
trial.6
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.7
How much is usually taken?
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.8 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.
Are there any side effects or interactions?
Statements that overuse of linden can cause heart problems9 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.10 11 In fact, linden is considered safe for use in
children12 and there are no known reasons to avoid it during pregnancy and breast-feeding.
At the time of writing, there were no well-known drug interactions
with linden.
