Medicinal raw materials. The aerial part (grass) is harvested in the flowering phase, cutting it off with a knife, scissors or secateurs. It is strictly forbidden to pull out the plant along with the roots, as this leads to the destruction of the thickets. Dry immediately after collection in the air in the shade, in attics, in ventilated rooms, but better in dryers at a temperature of 50-60 ° C, spreading a thin layer on paper, gauze, tarpaulin. The grass will need to be turned daily. Drying lily of the valley requires special attention, as the leaves and especially the flowers quickly turn black and deteriorate if the temperature is low or they are laid out in a thick layer. Dry grass is stored for 2 years, flowers – 1 year; their biological activity is monitored annually. Caucasian and Far Eastern lilies of the valley are also used.

Chemical composition. The plant contains cardiac glycosides: convallatoxin is isolated from flowers, convallatoxin, convallazid are isolated from leaves, and essential oil, organic acids, starch, manlin alkaloid are also found in the grass.

pharmacological properties.Biologically active substances of the plant normalize the function of the neuromuscular apparatus of the heart and hemodynamics, and also have a sedative property. After the appointment of lily of the valley in animals, an increase in cardiac activity, a slowdown in its rhythm, an increase in the minute volume of blood flowing through the heart, an improvement in the filling of the pulse, an increase in blood pressure, a decrease in congestion, and an increase in diuresis are noted. These phenomena are most pronounced with intravenous administration of the product, since after ingestion they are rapidly destroyed. Glycoside convallatoxin accelerates the movement of the contents of the gastrointestinal tract, enhances contractions of the stomach and intestinal motility, increases diuresis; increases blood pressure due to increased cardiac activity and narrowing of peripheral vessels.
