Chemical composition

There are many rumors and legends about this shrub plant. Some testify to it as an excellent medicine, others warn about the toxic substances it contains. The truth, as always, is in the middle - it is not without reason that rhododendron is recognized by both traditional and official medicine.

When people talk about this plant in a negative way, they always first of all mean the andromedotoxin it contains. This is a non-trivial substance that is considered a natural poison. It belongs to the class of glycosides. If the dose is exceeded, it can cause harm to the body, since it affects the functioning of the heart, disrupting the activity of its receptors. It first has a stimulating effect on the nervous system, then a depressant, and this can result in death. Its effect is in a certain sense similar to that of a drug. But in small doses, andromedotoxin has a calming effect, so the main thing is not to exceed the norm, and then, of course, this substance begins to work for human health.

The beneficial effect of rhododendron is also due to the tannins included in its composition. The plant is valued for its anti-inflammatory and health-promoting actions. Most of them are found in leaves.

Flavonoids, which are also a component of the chemical composition, also have an anti-inflammatory effect. In addition, they give the plant antioxidant and anticarcinogenic properties.

Essential oils contained in all parts of the plant also contribute to the creation of an anti-inflammatory effect and inhibit the proliferation of bacteria and viruses.

The flowers of the plant contain a lot of vitamin C, so it is recommended to collect medicinal raw materials at the time of flowering. Then it turns out to be especially rich in this vitamin, without which it is very difficult for the body to resist viruses and absorb calcium and iron.

Another component of rhododendron is gallic acid, it was used in medicine in ancient China and is characterized by antioxidant and antitumor properties. It also has a beneficial effect on the liver, protecting it from negative factors of various origins.

Ursulic acid, also part of rhododendron, helps burn fat, gives a slim figure, simultaneously stimulates muscle function and inhibits the proliferation of tumor cells.

Planting and caring for Caucasian rhododendron

Mountain Caucasian rhododendron develops well in the conditions of the middle zone. The plant prefers shady areas with moist soil. The shrub does not freeze at temperatures down to -29 °C. The optimal substrate is leaf soil, peat and coniferous litter in a ratio of 3:2:1.

Rhododendron is planted in the spring. It is better to prepare the planting hole in the fall so that the soil shrinks. The plant is removed at least 70 cm from other shrubs and trees.

Planting procedure:

  1. A hole 70 cm wide and 50 cm deep is dug in the area.
  2. Sand and broken bricks are placed at the bottom in a layer of 20 cm.
  3. The hole is filled with substrate to form a small mound.
  4. A seedling is placed on top. Its roots are covered with soil.
  5. Rhododendron is watered abundantly.
  6. A mulching layer up to 8 cm thick is poured into the tree trunk circle.

In the future, the rhododendron is provided with good care: watering, fertilizing, weeding. The plant requires abundant watering. Water is applied at the root at least 2-3 times a week. The moisture requirement per plant is up to 10 liters.

Attention! The first sign of a lack of moisture in rhododendron is drooping leaves and the appearance of dark spots on them.

Rhododendron is fertilized 2 - 3 times per season. In spring, rotted manure is applied under the bushes. Before and after flowering, use any fertilizer containing phosphorus and potassium. Compounds containing lime and chlorine should be avoided.

For the winter, young Caucasian rhododendron plants are covered with spruce branches. Just also agrofibre and other non-woven materials. They are mounted on a wooden frame. Winter watering and mulching the soil with humus protect well from frost. At the end of March, the shelter is removed, but the spruce branches are left. This will help prevent sunburn on the leaves.
