Specification & Spread
Roseroot rhizomes and roots — rhizomata et radices rhodiolae roseae
Roseroot — rhodiola rosea l.
Orpine family — crassulaceae
Other names: stonecrop.
It is a perennial succulent dioecious herbaceous plant with a large tuberous, many-headed rhizome, from which thick and thin adventitious roots extend.
The stems are usually numerous, erect, unbranched, densely leafy, 10-40 cm tall. The leaves are alternate, sessile, oblong-obovate or elliptical, entire or with several teeth on the top, fleshy, bluish-green.
The flowers are dioecious, tetramerous, less often pentamerous, yellow or slightly reddish, gathered in corymbose inflorescences located on the tops of the stems.
The fruit is a multiple fruit.
It blooms in June - July, the seeds ripen in July - August.
Spreading. It has a disjunctive Eurasian area. It is spread in the Urals and in the northern regions of the European part of the country, as well as in Central and Eastern Siberia and the Far East.
The rhizomes and roots of roseroot have a complex chemical composition.
The identified substances of various classes:
- phenol alcohol tirazol and its glucoside salidrozide (about 1%);
- flavonoids - derivatives of gerbacetin, tricin and kempferol;
- glycosides of cinnamon alcohol - rosavin (up to 2.5%), rosarin, rosin;
- flavonolignan rhodiolin;
- monoterpenoids - rosiridol and rosyridine;
- tannins (about 20%);
- essential oil containing cinnamon aldehyde and citral;
- organic acids;
- up to 10 different trace elements and other compounds.
Harvesting and storage of raw materials
Harvesting. The subterraneous organs are procured under licenses of harvesting organizations in areas designated by local forestry, starting from the end of flowering plants until mid-September. Before harvesting, you need to accurately identify the workpiece. After flowering, in the middle of summer, roseroot is hardly visible among the still lush greenery. The subterraneous organs are dug with a pick or narrow shovel. The raw materials are washed in running water and laid out to dry in the shade in a draft.
Security measures. The plant is recovering slowly, so it is necessary to alternate arrays of workpieces. The subterraneous organs of young plants are with 2-3 stems are not subject to harvesting. In addition, it is necessary to leave part of the subterraneous organs of old plants. The repeated harvesting of rhizomes on the same thickets is possible only after 10-15 years.
Drying. After wilting, the rhizomes are cut across into pieces with a length of 2-9 cm and dried in the shade or in dryers at a temperature of 50-60 °C (it is not allowed to dry in the sun). The dried raw materials on a fracture has a pink colour. The drying of large pieces of rhizomes leads to its deterioration, as the inside of the rot, the rhizomes become light and become brown in colour.
Storage. It is stored in a dry and well-ventilated area.
External signs of raw materials
Whole raw materials
The pieces of rhizomes and roots of various shapes. The pieces of rhizomes are up to 9 cm long, 2-5 cm thick, hard, wrinkled, with traces of dead stems and remnants of scaly leaves. From the rhizome there are few roots 2–9 cm long, 0.5–1 cm thick.
The surface of the rhizomes and roots shiny, grayish-brown, sometimes with a metallic sheen. When scraping the outer layers of the cork, a golden yellow layer is found. The colour on the break is pinkish brown or light brown.
The smell is peculiar, resembling the smell of a rose.
The taste is bitter and astringent.
Milled raw materials
The pieces of rhizomes and roots of various shapes, passing through a sieve with 7 mm diameter holes. The colour is pinkish brown. The smell is peculiar, resembling the smell of a rose. The taste is bitter and astringent.
Properties and application
Pharmacotherapeutic group. General tonic.
The pharmacological properties of roseroot
Roseroot extract has:
- stimulating effect on the central nervous system,
- improves the energy supply of the brain due to the intensification of the oxidative resynthesis of high-energy phosphates.
The roseroot preparations
- contribute to the normalization of metabolic processes. Roseroot has the properties of an adaptogen -
- increases the body's resistance to damaging environmental factors (pollution, noise, infections),
- activates non-specific resistance factors.
Roseroot is borrowed from the traditional medicine of Siberia. It is studied by prof. G.V. Krylov and prof. A.S. Saratikov at the Tomsk Medical Institute. Other types of roseroot are currently being studied.
Under the influence of roseroot preparations there are markedly increased:
5-10 drops of roseroot extract to be prescribed in the morning and in the afternoon to healthy people.
- with increased mental load (examination session, thesis defense, etc.),
- to improve performance and endurance, in long hikes, in difficult conditions of the Siberian winter.
In patients with neuroses roseroot:
- normalizes the mobility of the inhibitory and excitatory processes.
The roseroot preparations are taken at:
- asthenic conditions after infections, intoxications, physical or mental injuries,
- in the period of recovery after severe somatic diseases,
- with hypotension, vegetative-vascular dystonia,
- depressive states in patients with alcoholism,
- with schizophrenia with asthenic remission. For gross organic diseases, it is impractical to prescribe roseroot.
- Nervous overexcitement;
- pregnancy and lactation.
