Stocks of raw materials are large. Several tons of bark and tens of tons of fruits can be harvested annually. The main blanks are produced in the Transcarpathian, Lvov, Ivano-Frankivsk, Chernivtsi, Ternopil, Khmelnytsky, Vinnitsa, Volyn, Rivne, Zhytomyr, Kyiv and other regions.

The average annual harvesting of viburnum bark in the republic for three years (1974-1976) amounted to 2.8 tons.

Dry in attics under an iron roof, under sheds with good ventilation, laying out a thin layer (3-5 cm) on paper or cloth. The yield of dry raw materials is 38-40%.

According to GF-X Art. 185, GOST 8535-57, the raw material consists of tubular or groove-like pieces of bark 10-15 cm long and up to 2 mm thick, wrinkled on the outside, less often smooth, with small lenticels, brownish or greenish-gray, inside – smooth, light or brownish-yellow with small reddish spots and stripes. The smell is weak, peculiar. The taste is bitter, tart. Humidity is not higher than 14%. In raw materials, no more than 2% of pieces of bark with wood and branches, 15% of pieces of bark shorter than 10 cm, bark darkened from the inside – 5%, bark of other trees and mineral impurities 0.5% each.

The total ash content should not exceed 5%, and extractives extracted with 70-degree alcohol will need to contain at least 17%.

The bark, pressed, is packed in bales or bales of 50 or 75 kg. Store in packaged form in dry, well-ventilated areas on racks. Storage period up to 4 years. Raw materials are not subject to re-control.
