The rhizomes are the medicinal raw material of bergenia thick-leaved. They are harvested throughout the summer, until the end of the growing season. When harvesting, it is necessary to leave 10-15% of plants in the thickets for restoration. The roots are dug out of the soil, cleaned of earth and small roots, washed, cut into long pieces and dried (cannot be kept in heaps for more than 3 days to avoid decay). Freshly harvested raw materials are dried on hangers, then dried in dryers at a temperature not exceeding 60 ° C. Drying time within 3 weeks. The shelf life of raw materials is 4 years. The taste of raw materials is strongly astringent, there is no smell.

The liquid extract of bergenia (Extractum Bergeniae fluidum) is prepared as follows: 3 tablespoons of crushed raw materials are poured into a glass of boiling water and boiled over low heat until half of the original volume is evaporated. Take 30 drops 2-3 times every day. For douching, 1 tablespoon of the extract is diluted in 0.5 – 1 l of water. A decoction of bergenia (Decoctum Bergeniae): 10 g (1 tablespoon) of the rhizomes of the plant is poured into 200 ml of boiling water, placed in an enamel bowl and heated in a boiling water bath for 30 minutes, then cooled at room temperature for 10 minutes, filtered. The remaining raw materials are squeezed into an infusion, which is brought to the initial volume with boiled water. Take 1-2 tablespoons before meals 3 times every day as an astringent, hemostatic and anti-inflammatory agent for diseases of the gastrointestinal tract. ♦ Infusion of rhizomes (or leaves) of bergenia: 8 g of crushed raw materials are poured into 200 ml of boiling water, insisted, then filtered. Take 1 tablespoon 3-4 times every day. The infusion is also suitable for external use.

The plant is undemanding to the soil, but develops better on light, fertile, well-drained lands. It is propagated by seeds or division of bushes. Seeds are sown in March in boxes of greenhouses and covered with fine-grained sand. Seedlings dive into boxes, planted in open ground in June. For the winter they cover with foliage, as the plants develop poorly and by autumn they have only two small leaves. Blooms in the 3-4th year. Bushes are divided every 5-6 years in the first half of September. The resulting parts are seated at a distance of 30-40 cm from each other. In the first two weeks after planting, abundant watering is necessary. Productivity, depending on the place of growth, is up to 7 t / ha.
