Linden Tree - Features and Application

The topola, also known as lime tree, is a tree commonly found in the temperate zones of the Northern Hemisphere, growing up to 25–30 m high and living up to a thousand years. The species Tilia L. includes 35–50 species of plants, the most well-known of which in Europe are the small-leaved linden (Tilia cordata) and the broad-leaved linden (Tilia platyphyllos). The difference between these two species lies in the width of the leaves: the small-leaved linden has narrower leaves and more and lusher flowers. The leaves of the topola are characteristic, heart-shaped, and the flowers small, yellow, growing in flower clusters and intensely fragrant during the flowering period. The plant does not require special soil conditions, so it is willingly planted. A medicinal plant is the linden flower cluster, harvested during the flowering period (in June and July) on sunny days. The flowers are best dried in a shaded and airy room and then stored in an airtight container in a dry and cool place. Powdered linden flower cluster is available in pharmacies and herbal stores. In traditional medicine, linden syrup is also used, which is prepared from fresh flowers, sugar and water, sometimes with lemon juice. This syrup can be used as an aromatic additive to tea, but one should remember that it contains a lot of sugar.

The medicinal properties of lime flowers primarily stem from the presence of flavonoids (such as kemferol and quercetin). These compounds exhibit antioxidant, anti-inflammatory, antiviral, and anticancer effects. Lime flowers also contain mucilage, phenolic acids, tannins, and essential oil. Already in the Middle Ages, lime was used as a diuretic and moisturizing agent, while fresh flowers were added to blood infusions for their soothing effects. It was also believed to be a remedy for epilepsy, migraines, and hysteria. Today, lime is mainly known for its diuretic and anti-inflammatory effects, which is why it is often used as a supportive treatment in infections with fever or in colds. Its diuretic effects are attributed to the presence of flavonoids such as kemferol, quercetin, and p-coumaric acid, while increased sweating naturally lowers body temperature. It is also worth reaching for lime in cases of inflammation of the respiratory system, as it reduces dry cough attacks and soothes throat pain. This is due to the presence of mucilaginous compounds that coat the throat's mucous membranes. Inhalations with lime essential oil, on the other hand, reduce nasal mucosa congestion, which can help alleviate the feeling of a stuffy nose. Thanks to the presence of essential oil, lime has calming and nerve-relaxing properties. It is worth combining lime with other herbs with similar effects, such as melissa. A lime infusion with added milk and honey can help with falling asleep and improve sleep quality. The plant also has a diuretic and hypotensive effect (lowers blood pressure), which is attributed to the presence of terpenes. Due to its slightly astringent and antibacterial properties, a lime infusion can also be used for mouth rinsing in cases of oral inflammation. Interestingly, the medicinal properties of lime are also used in the production of charcoal from lime wood (Tiliae carbon), recommended for food poisoning. Externally, lime can be used for irritated and itchy skin, as it soothes inflammation and accelerates healing processes. Lime extract is also commonly used in the cosmetics industry, with the plant being found in the composition of shampoos, hair conditioners, and regenerating face and body creams. At home, a bath with lime infusion can be prepared, which moisturizes the skin and soothes nerves. To soothe irritation and care for the skin, the face can be washed with a lime infusion. It is worth noting that lime honey is one of the most valued honeys. The product had great significance already in ancient Egypt, where it was considered so valuable that it was placed in tombs during burials. Lime honey is known for its diuretic and antipyretic effects, which is why it can be used in colds, flu, and other infections with fever. Its regular use can help strengthen immunity. However, it is worth remembering that honey should not be subjected to temperatures above 40°C, as this reduces its health-promoting properties.

Lipa is most commonly used as a stew. During a cold, a tablespoon of dried flowers should be poured with a glass of boiling water and left under cover for 5-10 minutes. After removal, the stew can be given with the addition of honey and raspberries, as is usually recommended in folk medicine (this also increases the effect of the flu). During the cold, you should drink a teaspoon up to three times a day. Lipa should also be an ingredient in many of the medicinal products most often used in cold and flu, such as syrups (mainly for children), capsules, and drops. Lipa preparations, used in recommended doses, should not cause any side effects, but as with any product, they can cause allergic reactions (e.g., itching, watery eyes, redness, sneezing). In the case of using Lipa stew in the fight against infections, it is worth remembering that if the symptoms of the disease do not disappear or persist, a consultation with a doctor is necessary. Pregnant and breastfeeding women should consult with a doctor or pharmacist about the desire to use products containing Lipa.
