Inflorescences are used for medicinal purposes.

It occurs in deciduous (oak, hornbeam, beech, etc.) and less often in mixed forests almost throughout Ukraine. In the Carpathians, it rises to 950 m. In forest and forest-steppe regions, it mainly grows in watersheds, less often in floodplain forests, in the Steppe – in floodplain and ravine forests. Everywhere in the forest-steppe and in the north of the steppe regions it grows in forest belts and roadside plantations, also on the streets, in parks, etc. The main preparations are advisable in Khmelnitsky, Vinnitsa, Kyiv, Poltava, Cherkasy, Sumy, Kharkov, Donetsk regions.

Stocks of raw materials are large. Several hundred tons of inflorescences can be harvested annually. Billets are produced in all regions of Ukraine. The average annual harvesting of linden inflorescences in the republic for three years (1974-1976) amounted to 60 g.

Linden heart-leaved – a tree up to 25 m tall, with reddish or olive shoots. The leaves are alternate, long-petiolate, pointed at the apex, unequal-sided, heart-shaped, serrated along the edges, dark green above, bluish-green below, with tufts of brown hairs in the corners between the veins. The flowers are yellowish-white, fragrant, collected 2-11 in drooping half-umbels. The bract is folded, growing together with a common peduncle. The fruits are pubescent nuts, 4-8 mm in diameter. The plant blooms in late June-July. The fruits ripen in October.

In Ukraine, in addition to heart-leaved linden, broad-leaved linden also grows – Tilia platyphyllos Scop. and fluffy linden – Tilia tomentosa Moench. The chemical composition of the last few days has not been sufficiently studied. Probably, it can be used in the same way as l. hearty and l. broad-leaved.
