For medicinal purposes, the aerial part of the pickle is harvested: flowers, stems and leaves of the plant. The stem is cut off near the ground during the flowering of the plant, before the formation of seeds. Dry in bunches inflorescences down in a well-ventilated area or in the shade, avoiding direct sunlight. Store dried raw materials in paper bags in a dry place for no more than 2 years.

The aerial part of the plant contains a significant amount of silicic acid (about 10%), tannins (up to 10%), iridoids (haliridoside, harpagide, 6-deoxyharpagide, gluroside, 8-acetylharpagide), resinous, bitter and waxy compounds, flavonoids (0, 9% scutellarin), sterols, saponins, tannins, fatty (up to 45%) and essential oils, salicylic, caffeic acids and other substances.

MEDICINAL IMPORTANCE

According to studies conducted by Khvashchevskaya A.A., Fedko I.V. and other employees of the Siberian State Medical University, plants of the Lamiaceae family, in particular piculnik, can be recommended as a source of silicon in the treatment of pulmonary tuberculosis. It has been established that silicic acid is necessary for the strength, elasticity and normal functioning of the connective and epithelial tissues of the lungs, as well as the endocrine glands. Silicon in the body is able to increase self-protective functions. Active silicon compounds help to facilitate the removal of toxins, metabolites, and foreign substances from the body along with urine. The main function of silicon is to support an active metabolism in the body. Due to the presence of salts of salicylic acid and saponins in the composition of the pickle, the aerial part of the plant is used as an expectorant.
