Leaves are used for medicinal purposes.

In the wild, it is found in Moldova and Transcarpathia. In Ukraine, it is cultivated in the state farms of Soyuzlekrasprom, more often in the steppe and forest-steppe regions.

Woolly foxglove is a perennial (biennial in culture) herbaceous plant 50-150 cm high with a brownish-brown tap root and branched adventitious roots. Stems are rounded, erect, reddish-violet, pubescent in the upper part with long, glandular hairs, slightly branched. The leaves are rosette and stem, dense, oblong-lanceolate at the base of the stem, up to 20 cm long, with longitudinal veins prominently visible from the underside. Stem leaves are alternate, sessile, lanceolate, in the inflorescence pass into densely pubescent bracts. The inflorescence is a multilateral, dense raceme. Flowers up to 3 cm long. Pedicels short, calyx bell-shaped, five-toothed. Corolla brownish-brown, spherical swollen, two-lipped. Stamens 4, two upper ones shorter. Ovary bilocular, style with bilobed stigma. All parts of the flower are densely glandular-pubescent. The fruit is a cone-shaped, bilocular capsule up to 12 mm long. Seeds are cellular, light brown, 1.8 mm in diameter. Blooms in July – August. The fruits ripen in July-September.

Basal rosette leaves of the first year of life are harvested, and stem leaves in the second year. Prepared and dried in the same way as other types of cultivated digitalis (see foxglove purpurea, p. 185).

The yield of dry raw materials is 20-22%. The yield of dry leaves in the first year is 15 q/ha, in the second year – within 6 q/ha.

According to FS 42-614-72 raw material goctoht from leaves 6-20 cm long, 1.5-3.5 cm wide, green above, light green below with yellowish-brown veins. The smell is weak, peculiar. Taste is not determined – poisonous!

Humidity is not higher than 13%. In raw materials, no more than (percent) is allowed: leaves of a different color – 1, crushed parts passing through a sieve with holes of 2 mm – 2, organic and mineral impurities – 10 each.

The leaves are packed in bags of 20-25 kg or in bales weighing 50 kg. Stored in a group of potent raw materials in well-ventilated rooms, packed on racks or pallets, protecting from moisture. Small quantities are placed in tin cans.

Store up to 2 years, activity is controlled annually.

The leaves contain cardiac glycosides, the main ones are digilanides A, B, C, as well as steroidal saponins.

Newgalenic products of purified glycosides (celanide, lantoside, abicin, digoxin) are used as cardiac cardiotonic agents for heart failure, circulatory disorders.
