Procurement and storage . Sorrel roots (Radix Rumicis con-ferti), which are harvested in spring or autumn, are used to make medicines. The excavated roots are shaken off the ground, freed from the stems, washed in cold water, dried in the open air, cleaned of rotten and dead parts, split, if necessary, lengthwise and dried, spreading out a thin layer in the shade. Artificial drying is carried out at a temperature of 50-60°. 30-35% of dry roots are obtained. The finished raw materials are stored in a dry room that must be ventilated. The shelf life is 3 years. Raw materials are not released by pharmacies.
Chemical composition . Sorrel roots contain 8-12% of tannins of the pyrocatechin and pyrogal groups, up to 4% of anthraquinone derivatives, which include chrysophanic acid and emodin, nepodine flavonoid, essential oil, caffeic acid, calcium oxalate (up to 9%), iron in the form of organic compounds
Pharmacological properties and use. The biological effect of sorrel depends on the dose: in large doses, it acts as a laxative (the effect occurs after 10-12 hours), with small doses, an antidiarrheal effect is observed. Galenic sorrel products also have hemostatic, anthelmintic, choleretic and cholekinetic properties. The main indications for prescribing sorrel drugs are colitis, enterocolitis, hemorrhoids, anal fissures, worm infestation, hyperpolymenorrhea, hemoptysis, bleeding stomach ulcers, etc. A certain therapeutic effect is also observed in hepatocholecystitis, cholecystitis and cholangitis.
