Then the roots are uprooted manually or pulled out with a cable attached to the machine or tractor.  The entire underground part is collected, picking up small roots and bark, as they contain a large amount of berberine. The dug roots of barberry are cleaned from the earth and other impurities, while removing the blackened and rotten parts. Washing the roots is not allowed, since berberine is highly soluble in water.

Security measures. While harvesting the roots, it is necessary to leave intact at least one barberry bush for every 10 m2 of undergrowth. The harvesting of raw materials on the same thickets is allowed to be carried out no more than once in 10 years.

Drying. The leaves and roots are dried in a well-ventilated area, under a canopy in the open air or in dryers at a temperature of 40-50 ºС.
Storage. The raw materials are stored on racks in a well-ventilated area.

On the edge it is finely serrated, the teeth of the leaf are elongated into a soft needle. The venation is pinnate. The main vein slightly resembles a broken line. The leafstalk is naked, grooved, slightly winged at the top. The colour of the leaves from the upper side is dark green, matte, from the bottom is more light. The smell is peculiar. The taste is sour.

Roots.
The whole raw materials are cylindrical, straight or curved pieces of woody roots with a length of 2 to 20 cm, a thickness is up to 6 cm. There are coarse-fibrous fracture. The colour of the roots outside is grayish-brown or brown and lemon-yellow on the fracture. The smell is weak and peculiar. The taste is bitter.

Ground raw materials. The pieces of roots of various shapes is passing through a sieve with holes of 7 mm diameter.

Properties and application

In the experiment infusion and tincture of barberry:

  • increase bile secretion.

Berberine at full patency of the common bile duct causes:

  • dilution of bile without changing its quantity,
  • and in violation of the patency of the common bile duct increases the amount of bile and leads to its dilution.

The mechanism of action of barberry preparation associated:

  • like with antispastic effect on the gallbladder,
  • so with choleretic effect.

The relaxation of the gallbladder is accompanied by the cessation of pain.
