cyanosis does not form a large bush, the raw material collection of wild plants is difficult, the old plant rhizome rots inside.Cultivated in Belarus, in many parts of our country.
collection and drying.Collect the underground authorities in late August - September, or in the spring during the formation of the stems when the roots contain a maximum of biologically active substances.Collect only young plants.Plants with multiple stems, give poor raw materials, they are left for seed multiplication.Plants dug with shovels and plows plowed under culture in the first or second year of culture, shake off the ground with a knife cut the entire aboveground part, the rhizome is cut lengthwise into 2-4 pieces, cut rotten or damaged by pests of the roots and quickly washed in running water.During prolonged washing water becomes frothy, as washed saponins - the main active ingredients.If the raw materials pre-treated well, cut into pieces, remains of soil washed out quickly, and the residence time of the raw material in the water is reduced.Well Washed raw materials has a yellowish-white roots.
dried in the sun, in attics, under eaves or in the dryer at a temperature of 50-60 °.
medicinal raw materials.Ready raw material - rhizome with the roots of cyanosis (Rhizoma cum radicibus Polemonii) consists of a thick, creeping rhizomes or direct grayish-white with remnants of the stems no longer than 1 cm, or without them.Rhizomes are usually cut lengthways, in the fracture yellowish-white.Roots thin, branching, entangled with each other, yellowish, in a break, white.
The smell is very weak, kind of.Dust in the packaging or raw material grinding causes sneezing.Taste bitter.
GOST 3557-69 admits: moisture not more than 14%;ash no more than 13%;shredded pieces, passing through a sieve with a hole diameter of 1 mm and not more than 5%;rhizomes and roots of debris (scree) not more than 15%;remnants of the stems longer than 2 cm of not more than 5%;brownish rhizomes break in not more than 3%;Organic impurities are not more than 1% of mineral - less than 2%.
chemical composition.Rhizomes with the roots of cyanosis comprise 20-30% triterpene saponins, highly soluble in water and dilute alcohol.Hemolytic raw index is 7000, and in some cases up to 11 000. Apart from saponin containing resinous substances, organic acids, essential oil traces.
action and application.Cyanosis is used as an infusion or decoction of 6-10 g of raw material per 200 ml of water and 1 tablespoon 3 times a day after meals and in the form of tablets of dry extract - as an expectorant and sedative.Acts 8-10 times stronger than valerian.The same decoction is prescribed along with the infusion of herbs uliginose ('10 per 200 ml of water) 3 tablespoons before meals for the treatment of gastric ulcer and duodenal ulcer.This calming effect is combined with cyanosis cottonweed wound-healing effect.Use and tablets containing extracts of these plants.
