COLLECTION AND DRYING OF RAW MATERIALS

Harvest underground organs in August – September or early spring. The plants are dug up, the seeds are shaken into the hole formed during digging, the ground is shaken off there, the stem is cut off with a knife, small roots are removed, the thick ones are cut into pieces of 15-20 cm, washed, then cut lengthwise for quick drying, the rotten parts are cut out and again rinsed in running water. Dry in attics, under sheds or in dryers at a temperature of 30-40°C. With slow drying, poor ventilation, the white roots turn brown inside, which makes them unsuitable for use. The shelf life of raw materials is 3 years.

PHARMACOLOGICAL PROPERTIES

The biologically active substances of comfrey have an enveloping and emollient effect, lower blood pressure and strongly stimulate respiration, increase tone and increase the contraction of the muscles of the intestines and uterus, promote bone tissue regeneration, stimulate cell growth and repair damaged tissues. The positive effect of comfrey infusion is manifested in reducing pain in the gastrointestinal tract, improving digestion, and strengthening the epithelization of the mucosa affected by the inflammatory process. A similar process occurs in diseases of the upper respiratory tract: expectoration of sputum improves, the function of the epithelium, significantly reduced by the inflammatory process, is restored.
