Blueberry leaves (Folium Myrtilli) are also used, collected in July-August. The raw material consists of shapeless, strongly wrinkled, soaked spherical berries within 5 mm in diameter. At the top of the fruit there is a remnant of the calyx in the form of an annular rim surrounding a swollen disk, in the center of which is the remnant of a column or scar. The fruits are almost black, with a reddish tinge. In the red-purple pulp of the fruit are numerous small seeds. The smell is weak the taste is sweet and sour, slightly astringent. Decoctions of blueberries are purple-red in color, from the addition of acid, the color becomes more red, and from alkali, the decoction takes on an olive green color.
