Linden: benefits, dosage, contraindications

Mis à jour le

Linden trees are deciduous, reaching 20 to 30 meters in height and are widespread throughout Europe and northern Asia. The leaves, heart-shaped at the base and pointed at the tip, make the tree easy to identify. The linden bears small yellowish flowers. These appear in the leaf axils and release a subtle, delicate yet intense fragrance when they bloom. The fruit is a rounded capsule that contains a single seed. The flowers, leaves and sapwood are the parts most used medicinally. The flowers contain flavonoids: quercetol heterosides, kaempferol heterosides, mucilages, tannins and essential oils: linalool, farnesol, eugenol, 1,8-cineole. The sapwood contains phenolic acids, tannins, fraxoside, esculoside and amino acids. When taken 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 cough. The linden sapwood (the part between the bark and the heartwood) is used orally for liver and gallbladder diseases, and for cellulite (purifying).

Properties


Sedative

full-leaffull-leaffull-leafempty-leaf

A recent study using Tilia americana and Tilia mexicana showed that an extract made from the inflorescences, administered orally to mice, could have anxiolytic and sedative effects. nnThese effects would act through the GABAergic system and the molecules involved in this action would be flavonoids (heterosides of quercetol and kaempferol) and possibly volatile oils, notably citral, citronellal, citronellol, eugenol and limonene.nn
