Infusions and decoctions of medicinal plants
Medicinal raw materials are rarely used in the form of a powder, which is washed down with water.So used, for example, rhubarb root, leaf foxglove, some fees.Most of the raw materials of finished dosage forms and preparations.
infusions and decoctions - water extraction, get them out of different kinds of medicinal raw materials.Chopped raw material was placed in a porcelain-enameled or vessel which is heated in advance in a water bath for 15 minutes, pour the calculated amount of distilled water at room temperature and heated under the hood in a water bath with frequent stirring.
Infusions heated for 15 minutes concoctions - for 30 minutes.The flask was then removed from the water bath and cooled at room temperature: infusions - 45 minutes, broths - 10 minutes.By insisting transfer of biologically active substances in the solution proceeds.After cooling, the extract is filtered, the residue is squeezed plant material is then added to a prescribed amount of water.Due to the fact that water for extrac
Infusions are usually prepared from the leaves, herbs, flowers and herbal teas - bark, rhizomes, roots.Exceptions are plants containing essential oils, which is prepared from extracts to reduce the loss of aromatics.
When preparing aqueous extracts of raw alkaloid added citric acid, tartaric acid or hydrochloric acid to increase the solubility of the translation result alkaloid salts of these acids.
decoction of raw materials containing tannin (bearberry leaves, oak bark, roots coils and cinquefoil, stems alder and others.), Filter immediately after removal from the water bath, without cooling.
In some cases extracts prepared without heat, cold water at room temperature (marshmallow root).
To speed up the preparation of aqueous extracts are concentrates produced at the factory.
prepared infusions and decoctions at home from the pharmacy packaged, minced raw materials in accordance with the instructions supplied.Raw dosed tea or tablespoons, placed in a porcelain or enamel bowl, brewed with boiling water, close lid and insist 20, 30 or 60 minutes.Prolonged insisting utensils must be covered with a towel.For infusions contents boil on low heat, strain through cheesecloth or a metal strainer and use, divided into unit doses.
Medicinal charges - a mixture of several kinds of ground, less solid plant material - sometimes mixed with salts, essential oils.Prepare them in pharmacies or in the factories, and the extraction of them are available in the home.
The structure of charges includes various plant parts: roots, bark, grass, leaves, flowers, fruits, seeds.
When preparing charges chopped vegetable raw materials are weighed and mixed on a large sheet of paper or in an enamel basin.Leaves, grass and bark pre-cut, leathery leaves ground into a powder, roots and rhizomes are cut or crushed, fruits and seeds are passed through rollers or mill.Small seeds and berries, small flower baskets and flowers take one piece (except a linden).
Ready taxes at home are best stored in glass jars large capacity, closed with plastic lids.Dosing every time the collection is thoroughly mixed a tablespoon, as the storage of its components may delaminate.
Depending on a part of the collection of raw materials prepared infusions or decoctions.If a part of the collection includes scented essential-oil plants, some of them, as a rule, prepare the infusion.Boiling is not allowed because the essential oils are volatile substances that evaporate with the water.
Medicinal charges contain various biologically active compounds that simultaneously with treatment of the underlying disease enrich the body further in various vitamins, mineral compounds and other components of the plant, enhances the body's resistance, a beneficial effect on the central nervous system, improves the blood, neutralizing "slag" andaccelerating the excretion from the body.The impact on physiological processes carried out in this case, natural, more characteristic of the body with organic substances.Allergic complications of the treatment fees are observed much less frequently than with other drugs.
As mentioned above, in the training camp is usually observed synergy between the highly aggregated substance (effect of one substance intensifies the other).
Versatile effects of biologically active plant substances often succeeds.Thus, the appointment of a complex collection for liver Helichrysum substances increase the secretion of bile, gastric and pancreatic juice, improve the tone of the gall bladder, change the chemical composition of bile.Substances contained in corn silk, a beneficial effect on metabolism, improve bile secretion.Substances barberry reduce and relieve pain, depending on the presence of alkaloid berberine having spasmolytic effect.With the same purpose, often in such a collection is introduced and peppermint leaf.
addition of organic substances charges contain macro - and microelements.Recent involved in metabolism, are in functional interaction with enzymes, vitamins, hormones and other biologically active substances.The presence of copper,
manganese, iron, molybdenum, proteids metalloflavo composition promotes the transfer of electrons in the living cells.Manganese, copper, zinc, cobalt microdozes stimulate the production of antibodies, increases the body's resistance.Copper, iron, zinc, cobalt, reduce the permeability of biological membranes.
That is not a complete list of those substances that are introduced into the patient's body for the treatment of multi-component assembly: proteins, amino acids, carbohydrates, lipids, enzymes, vitamins, organic acids, alcohols, aldehydes and ketones, esters of phosphoric acid and other acids, phytosterols, resinous and tannins, glycosides, terpenoids, coumarins, amines and amides, betaines, choline and choline esters, purines, and pyrimidines, alkaloids, bitter substances and many others.
Action medicinal plants largely depends on the dose.rhubarb root, for example, applicable in high doses as a laxative and a small - on the contrary, it exerts anchoring effect.Different doses of spicy and bitter raw stimulate or inhibit the secretion of gastric juice.Furthermore, as stated above, saponin has versatile effects.This explains the fact that prescriptions, different purposes, frequently identical components but in different amounts and in different combinations.Prepare a water extraction from the collection of mostly so.
The pre-heated kettle is filled collection, pour boiling water, cover with a towel and leave for 1-2 hours of infusion.
can prepare infusions and thermos, leaving the mixture, insisting on the night.Thermos is essential for the preparation of drugs from the flowers of chamomile and fees, in which they belong.In dry inflorescences of this plant contains sesquiterpene matricin that during heat treatment is gradually transformed into hamazulen possessing anti-inflammatory, anti-allergic, disinfectant action.It, like the other components of the essential oil is difficult to dissolve in water, but insisting on prolonged goes into solution.When cooking infusions in a thermos essential oils of other plants and do not evaporate.
To prepare the broth into an enamel pan, low-capacity poured a measured amount of the collection, pour cold water, close lid and heated on low heat.Boil 5 minutes and insist for 1 hour.The prepared infusion or decoction filter.
In all cases, to obtain complete extraction of acting of substances take much more than the preparation of similar drugs in a pharmacy.Therefore, take the medicine more often made no spoons, and 1/2 cup - 100 ml, and sometimes more.If the drug is prepared every day, it does not undergo microbial spoilage and can be stored at room temperature for a day.With more should be stored in the refrigerator.
