Linden: Benefits, Dosage, Contraindications

Updated on

Lindens are deciduous trees reaching 20 to 30 meters in height and are widespread throughout Europe and northern Asia. The heart-shaped leaves at the base and pointed at the top allow for quick identification of the tree. The linden bears small yellowish flowers. These appear in the leaf axils and release an intense, subtle, and delicate fragrance when in bloom. The fruit is a rounded capsule containing a single seed. The flowers, leaves and sapwood are the most commonly used parts in therapeutics. The flowers contain flavonoids: quercetin heterosides, kaempferol heterosides, mucilages, tannins, and essential oils: Linalool, farnesol, eugenol, 1,8-cineole. The sapwood contains phenolic acids, tannins, fraxoside, esculin, and amino acids. Orally, linden leaves and inflorescences are used for colds, nasal congestion, throat irritation, palpitations, sleep disorders, and nervous tension. It is also used as a diuretic, antispasmodic, and expectorant for coughs. Linden sapwood (the part between the bark and the heartwood) is used orally for liver and gallbladder diseases, and for cellulite (detoxifying).

Detoxification

Linden sapwood stimulates the liver (cholagogue) and kidneys. It facilitates the elimination of certain wastes such as uric acid responsible for joint inflammations or kidney stones. It also has choleretic actions, meaning it optimizes the regular secretion of bile, which is favorable for people with slow and difficult digestion.

Properties


Sedative

full-leaffull-leaffull-leafempty-leaf

A recent study using Tilia americana and mexicana showed that an extract made from the inflorescences, orally administered in mice, could have anxiolytic and sedative effects. These effects are thought to be mediated by the GABAergic system and the molecules involved in this action would be flavonoids (quercetin and kaempferol heterosides) or even volatile oils, notably citral, citronellal, citronellol, eugenol, and limonene.
