Canadian goldenrod: medicinal properties and contraindications, application

Canadian goldenrod is easy to grow in your summer cottage. It is very useful from a medical point of view and can help with many diseases. But for environmental services, this is a vicious weed that must be destroyed.

Description of the Canadian goldenrod

The Latin name for the plant is Solidago canadensis. In Russian, a tracing paper from Latin is also found as a name: Canadian solidago.

Herbaceous perennial plant with a height of 50 cm to 2 m. Stems are straight, erect, do not branch. Goldenrod shoots are densely covered with narrow lanceolate leaves, arranged alternately. The leaf blades are pubescent on the underside and "glabrous" on the upper side. The edges are jagged. The root system develops horizontally.

Inflorescences are formed at the tops of the stems and are pyramidal in shape. Since there are several of them, all together they form a wide panicle. The color of the flower petals is yellow.

The fruits of Canadian solidago are cylindrical achenes. For better distribution, they are "equipped" with a tuft of bristles. Thanks to this adaptation, the wind picks up the seeds and carries them away from the mother plant.

Some species of the genus Goldenrod were introduced into the culture and are now grown in gardens. Canadian has served as the parental form for many varieties. Moreover, many of them are much more convenient for growing in a flower bed, since their maximum growth is much lower than 2 m.

The Canadian Patio solidago variety is most convenient for gardeners, since it does not grow above 60 cm. But it retains all the properties of a wild ancestor. Hybrids can grow up to 1.5 m, which is not very convenient when caring for a flower bed. And some of them are also very whimsical: Arends' goldenrod can only be grown in greenhouses.

There are more than 80 species of goldenrod in the world, but only Canadian has served as a parent form for many varieties

Where and how it grows

The natural area of ​​distribution of the Canadian goldenrod is the east of the North American continent. As a dangerous invasive weed, the plant has already spread throughout the non-tropical zone of the Northern Hemisphere.

Under natural conditions, Canadian goldenrod prefers to grow along roads and in settlements. In Central Russia, the plant managed to naturalize and is already found everywhere in a feral state.

Flowering features

Plus, and it is also a minus for allergy sufferers, the Canadian goldenrod is that the time of its flowering falls on July-September. Most of the plants are already bearing fruit by this time. The exact timing of flowering depends on the region and the weather in the spring. The colder, the later the goldenrod will bloom. But this applies to all plants.

The seeds ripen in August-October. If seeds are needed for subsequent propagation, this moment should not be overlooked. Achenes are easily separated from the bed and go on an independent flight.

Canadian goldenrod - poisonous plant or not

Yes, goldenrod is poisonous. Its root system is especially dangerous. The release of poison into the soil is the basis for the success of the Canadian goldenrod in capturing new spaces. It kills everything from bacteria and fungi to other flora.

For a person, preparations from Canadian solidago can also be dangerous if used uncontrollably. Before using this traditional medicine, you should consult your doctor.

The value of the Canadian goldenrod as a honey plant

From the point of view of the amount of products received, Canadian goldenrod is a medium-level honey plant. But its advantage is that it starts flowering at a time when most other plants have already formed fruits. If the flow rate in the season was small, bees can get honey on the Canadian goldenrod variety.

Honey productivity of the Canadian goldenrod

The plant can produce 100-150 kg per hectare. But this is only if there are favorable conditions. The combination of factors to get the most out of a Canadian species is relatively rare. Therefore, one should count on bribes of less than 100 kg.

Honey collected by bees on the Canadian goldenrod variety is suitable for those who are contraindicated in other types

The value and chemical composition of the Canadian goldenrod

In the Leningrad region, research was carried out on the Canadian goldenrod to determine its value for medical purposes. Along the way, it turned out that the plant is not afraid of low temperatures, but loves high air humidity very much. In the year of research, the weather was cool and rainy.

For the study, soil samples and goldenrod leaves were taken. The "standard" part of the chemical composition of canadian solidago grass:

  • flavonols;
  • alkaloids;
  • carbohydrates;
  • polysaccharides;
  • hydroxycinnamic acids;
  • lipophilic substances;
  • triterpene saponins.

Diterpenoids are present in the roots. From trace elements - a significant amount of silicon.

The "non-standard" part of the chemical composition includes the elements present in the soil on which the goldenrod grows. He is able to extract these substances from the soil and accumulate them in the aboveground part. Especially dangerous in this respect is the high content of copper in the leaves of the plant. Studies in the Leningrad region have shown that canadian goldenrod is able to accumulate these substances. The ratio of the amount of trace element to the permissible concentration in the plant is higher than in the soil.

The chemical composition of plants directly depends on the presence of trace elements in the soil.

Useful properties of the Canadian goldenrod

In traditional medicine, Canadian solidago herb is used as an anti-inflammatory, antispasmodic and diuretic. It is also used for hypoazotemia - a high concentration of products containing nitrogen in the blood. The plant is used in complex preparations:

  • Prostanorm (Russia, for the treatment of prostatitis);
  • Marelin (Ukraine, antispasmodic, diuretic and anti-inflammatory);
  • Fitolysin (Poland, diuretic, anti-inflammatory, antispasmodic).

Canadian and common goldenrods are used for the same diseases:

  • urinary system;
  • kidney stones;
  • prostatitis;
  • skin;
  • joint problems;
  • bruises and open wounds;
  • to enhance immunity;
  • with severe diarrhea or vomiting;
  • some heart diseases;
  • for any diseases that cause an increase in the level of uric acid in the body;
  • in the case of a reduced excretion of urea in a natural way, which causes metabolic diseases.

The excretion of urea is also reduced with blood cancer and alcohol abuse.

But although the scope of application of the Canadian and common goldenrod is the same, their photos and descriptions are different. This matters, since the effect of the former is stronger. It is also undesirable to confuse plants because you can already get a fine for growing a Canadian variety in Belarus.

The use of Canadian goldenrod in traditional medicine

The use of the Canadian goldenrod species in traditional medicine is almost the same as in traditional medicine. But here he is also credited with some "magical" properties and is used not in a complex, but as a separate tool. For this, decoctions and infusions are prepared. Sometimes added to tea.

Decoctions and infusions recipes

The concentration of decoctions and infusions made from the Canadian solidago species is the same. The only difference is the volume of fluid required to treat diseases. It makes no sense to describe the preparation method separately. Two recipes are enough: decoction and infusion. Further, for each disease, it will only be necessary to adjust the volume.


A tablespoon of goldenrod is poured with a glass of boiling water and heated in a water bath for 5-10 minutes. Insist for three hours and filter through cheesecloth.


A tablespoon. pour a glass of boiling water, close the container and insist until it cools. Filtered and consumed according to indications.


The same decoctions and infusions from Canadian solidago, but in a much lower concentration: two teaspoons for two glasses of water.

There are two brewing methods:

  • the grass is poured with cold water, turned off immediately after boiling and kept for two minutes;
  • raw materials are poured with boiling water and insisted for ten minutes.

Tea is drunk not for treatment, but for the prevention of diseases.


Self-sufficient product harvested by bees from the flowers of canadian goldenrod. It does not need to be specially prepared, but it can be mixed with other products, increasing the effectiveness of honey.

Admission and application rules

Solidago Canadian preparations are taken half an hour before meals. The multiplicity and volume depend on the specific disease. But before you start taking herbs, be sure to consult your doctor. Canadian goldenrod may not be compatible with the remedies already prescribed. In addition, the plant is slightly poisonous, and an overdose can cause poisoning.

Attention! Broths and infusions are stored in a cool place for no more than two days.

The required volume of liquid is prepared based on the shelf life and the type of disease. In some cases, it is easier to buy a ready-made drug that comes in the form of a liquid extract, tablets or paste.

Phytolysin is not an ointment, but a paste from which a suspension is independently prepared for internal use

With diseases of the genitourinary system

In diseases of the genitourinary system, the broth is consumed four times a day for ½ glass. The duration of the course must be indicated by the doctor.

Also, honey is used to normalize the functioning of the bladder. This is more of a preventive measure, but it can also be used in case of illness. A teaspoon of honey is dissolved in 125 ml of water. It is taken twice a day, 60-65 ml.

The second recipe does not contain exact data, except for the amount of honey. 100 g is mixed with lemon juice and rosehip infusion. Take before meals.

For kidney stones

For kidney stones, a decoction is recommended, which is taken three tablespoons three times a day. You need to use the product under the supervision of a doctor. Large stones can cause severe pain as they pass through the ureter.

Liver disease

It is more rational to use honey here. It is mixed with black currant in a 1: 1 ratio and taken in a teaspoon two hours before meals. The volume of the mixture is not regulated, but it is better to do it little by little and often. Store the finished product in the refrigerator.

Attention! Decoction and infusion of Canadian solidago for liver diseases are contraindicated.

With prostatitis

For men with inflammation of the prostate gland, Canadian goldenrod, as the only remedy, is useless for treatment. A miracle will not happen when using drugs from this plant. But you can delay the treatment and "transfer" acute inflammation into chronic. The former is fairly easy to stop with antibiotics. The second is practically not amenable to treatment. In any case, you need to check with your doctor whether antibiotics and Canadian solidago are compatible.

In traditional medicine, an auxiliary drug Prostanorm is prescribed for prostatitis. It includes:

  • St. John's wort;
  • licorice roots;
  • canadian goldenrod;
  • Echinacea purpurea roots.

Prostanorm is contraindicated in diseases that do not require immunostimulants, and acute glomerulonephritis

For the treatment of bruises and wounds

A decoction of canadian goldenrod accelerates the healing of open wounds and bruises. In case of injury, the urea content in the body rises. Goldenrod reduces the level of this substance, normalizing metabolism.

For skin diseases

In case of skin diseases, the infusion is not only consumed orally to excrete uric acid. The grass will not help against the fungus, but a compress on an open ulcer will not allow a bacterial infection to get hooked on the wound.

Goldenrod hydrolat is also used for compresses in treatment

  • dermatitis;
  • furunculosis;
  • pustular rash;
  • eczema;
  • burns;
  • open wounds.

The method of treatment is simple: the drug is applied to an irritated or damaged skin area.

Hydrolatum Canadian solidago for external use is often produced in the form of a spray

With joint pain

If joint pain is caused by gout, then it is the preparation of canadian goldenrod that is one of the best remedies for treatment. The disease develops as a result of metabolic disorders, in which uric acid crystals are deposited in the tissues. Goldenrod is one of the most potent agents that accelerate the excretion of urea from the body.

From foot and nail fungus

Only fungicide preparations help against fungal diseases. Onychomycosis is not as safe as it might seem. If delayed with treatment, the mycelium grows into the bones and internal organs. Fungi are very well protected from external influences by the nail plates or the epidermis.

Neither ointments nor tinctures can cure this disease. Preparations from the Canadian goldenrod can only be used as an adjuvant. According to the principle "it will not be worse, although it is unlikely to do better." For the appointment of this treatment, you need to consult a doctor who will select the appropriate antifungal agent.

When tired

In a state of constant fatigue as a result of spring beriberi, goldenrod tea will help. Drink it 3-4 times a day after meals.

To strengthen the immune system

To strengthen the immune system, the infusion is consumed in a course of two weeks. Then they take a break for two months. The courses can be repeated. During the course, the infusion of Canadian goldenrod is drunk 50 ml three times a day.

Application in cosmetology

Infusions and decoctions are not used as cosmetics. In this area, canadian goldenrod hydrolat is used. The drug is recommended for people with problematic and oily skin.

With regular use, hydrolat helps to cope with acne and pustular rashes. But do not forget that these are hormonal problems that will not go away just from rubbing the skin with a goldenrod remedy.

Regular use of hydrolat helps to improve the quality of oily skin. It loses its oily sheen and dries. The product relieves irritation and redness, makes it velvety.

Extract from the Canadian goldenrod variety will eliminate redness and improve the quality of the skin

Limitations and contraindications

With external use, there are practically no restrictions, with the exception of a possible allergic reaction. Oral use of Canadian goldenrod preparations has serious limitations. Infusion and decoction should not be taken:

  • during pregnancy;
  • with liver diseases;
  • with Fanconi syndrome;
  • with Hodgkin's lymphoma;
  • with hepato-cerebral dystrophy;
  • with xanthinuria;
  • on a low protein diet.

Restrictions do not apply to honey, in which the active substances of canadian goldenrod are present in trace amounts.

Collection and procurement of raw materials

Only leaves and inflorescences are suitable for harvesting. The collection of raw materials is carried out after the plant blooms. When harvesting, the tops of the stems of Canadian goldenrod with a length of 15-20 cm are cut off, the inflorescences are separated and the leaves are removed by hand. The resulting raw materials are dried under a canopy in the shade or in a well-ventilated area. The herb has a shelf life of three years.

Application in landscape design

The Canadian goldenrod culture was introduced back in the 17th century. Since then, it has been used in landscape design. It is grown:

  • in a group of plants;
  • as a monoculture in a flower bed;
  • for decoration of garden buildings
  • along the perimeter of the site as a green fence;
  • along the paths as a curb culture.

Tall varieties of goldenrod are used for the fence, and dwarf ones for the borders.

Canadian solidago is also cultivated for the sake of cut bouquets.Blooming goldenrod lends itself well to drying and can be used as an element for dry compositions.

Breeding features

In reproduction, the Canadian goldenrod uses all possible means:

  • seeds;
  • dividing the rhizome;
  • cuttings.

One plant can produce up to 100,000 flying seeds. Due to their unpretentiousness, they do not even require preparation before planting.

The seeds of the Canadian goldenrod species are very small and cannot be planted evenly.

Planting and leaving

Being a tenacious weed, Canadian goldenrod does not require special growing conditions. It is enough to find a suitable place, not particularly worrying about the lighting. Subsequently, it is necessary to control the expansion of the plant.

Recommended timing

The timing of planting solidago canadian depends on the chosen breeding method. Seeds are sown directly under the open sky in early spring. Since they are small, later the sprouted shoots are thinned out.

The green cuttings are cut after they are nearly full. Planting material is harvested in the same way as for any other plant. But grafting is the most inconvenient way for reproduction of Canadian solidago. The plant is best rooted in artificial fog conditions. Buying an installation for the sake of one flower bed is irrational. Therefore, it is better to use the division of rhizomes of canadian goldenrod.

This procedure is best done in late autumn, but before the onset of frost. For the winter, the aboveground part of the Canadian goldenrod is cut off. At the same time, you can dig up the plants and separate them.

Site selection and preparation

The Canadian goldenrod species prefers fertile soils, but survives well on poor ones. The same with lighting: prefers sunny places, but can grow in light shade.

Loves mineral fertilizers: potassium salt and superphosphate. If you need luxurious flowers, when preparing the soil, you need to immediately add the necessary fertilizing.

The site must be chosen so that during floods and autumn rains, the groundwater is below the roots of the goldenrod. With excessive moisture, the root system can rot. This point must be taken into account when watering. During flowering, the plant needs more water, but it is important not to overdo it.

Landing algorithm

Seeds are sown in early spring on loosened soil without prior preparation. It is not necessary to deepen them, since they are very small. It is enough to lightly sprinkle the achenes with soil and gently pour from the watering can. When the sprouts grow up, they are thinned out so that there is a distance of 20-30 cm between them.

When planting separated rhizomes, the rules are the same as for other perennial herbaceous plants. That is, after preparing the soil, the seedling is placed in a hole and covered with earth along the root collar. If the planting is carried out in the fall, the weather forecast is taken into account. The goldenrod must be planted so that it has time to settle down in a new place before the onset of frost.

The root system of the Canadian solidago species is very powerful, it is difficult to remove it from the ground.

Growing features

Caring for Canadian goldenrod, in fact, contains only two requirements: control of growth and pruning of stems before wintering. The plant is very hardy and does not require special shelter for the winter. But the stems are cut at a height of 15 cm above ground level or below.

Every 3-4 years, the goldenrod must be dug up and the rhizomes must be divided. Solidago Canadian grows very strongly. If you do not regularly carry out the division procedure, the plant will fill the entire area.

During the flowering period, more intensive watering is carried out than at any other time. This is where the care of goldenrod ends.

Pests and diseases

The Canadian newcomer in Eurasia has no natural enemies and diseases. This fact also contributes to the rapid spread of the weed in the surrounding area. But for a gardener, this circumstance may turn out to be a plus: the Canadian solidago will cope with pathogenic microorganisms in the soil on its own, and there are no insects that eat it in Russia.

Interesting facts about the Canadian goldenrod

According to some sources, the Canadian goldenrod has interesting, little-known properties. In particular, they found out that the plant releases toxic substances into the soil that suppress the development of pathogenic microorganisms. For some reason, this phenomenon is called "soil cleansing." Unfortunately, these same substances suppress the development of native flora, destroying farmland and surrounding plants.

You can also find claims that a decoction of a mixture of Canadian goldenrod and cloves suppresses the development of a yellow fever mosquito. The information is questionable. The homeland of this species of blood-sucking insects is Africa. It was introduced to South and Central America. Due to global warming, the mosquito's range has expanded to the southern regions of Russia. But it is very difficult for a female insect to meet a person with an "African" disease there. Therefore, the species does not pose a particular danger.

The mechanism of action of the decoction is unclear. It is unclear why, but there is no mention of its effects on other mosquito species. And he must act on them too. In addition, before humans, the Canadian solidago species and the yellow fever mosquito have not been encountered.

Either the development of the larva or the laying of eggs by the female can be suppressed. But the larvae develop in water bodies. If you pour a broth of Canadian solidago there in hundreds of liters, then everyone will be poisoned, even frogs. It is also impossible to introduce a decoction into the female's body. Most likely, it is implied that the agent repels mosquitoes from a person. But this is the merit of the carnation, not the goldenrod.

There is only one fact that you can check without fear for your life and natural environment. This is the ability of a plant to dye white tissue yellow.


Canadian goldenrod can serve as a garden decoration, but it can also harm the owner of the site. If you intend to plant a plant, you must first consult whether a ban is imposed on it in a given area. If Canadian solidago is needed for medicinal purposes, but is prohibited for cultivation, it is easier to buy industrial preparations.
