Rosyanka rotundifolia

Name: Rosyanka round-leaved


Rosyankovye – Droseraceae.

Parts used: grass.

Pharmacy name: sundew herb – Droserae herba (formerly: Herba Droserae).

Botanical description.This perennial plant forms a basal rosette of petiole leaves, completely covered with glandular hairs. The latter secrete a sticky secret to which small insects stick. Then they are digested with the help of another enzyme secretion. In this way, a plant that lives on soils poor in nitrogen obtains the necessary nitrogenous substances for itself. A peduncle develops from a leaf rosette, up to 25 cm in height, iridescent pink, often slightly curved, delicate, without leaves. White flowers with a diameter of 5-8 mm are collected in a racemose inflorescence. Blooms in July-August. Sundew is found in upland bogs. She is threatened with extinction, so she is protected and cannot be collected. In the form of tea, its effectiveness is negligible; galenic products deserve more attention, besides, other medicinal herbs are added to them.

Collection and preparation. The whole flowering plant without roots has a healing effect. To preserve the active ingredients, sundew must be dried very quickly at a temperature not exceeding 40 ° C.

Active ingredients: naphthoquinone derivatives, flavonoids, enzymes and other not yet fully identified substances.

Healing action and application. Scientific medicine does not need sundew in the form of tea, but tincture and liquid extract are an integral part of many medicinal products for coughs, especially reflex, and whooping cough in babies. In addition, there is evidence that these foods relieve severe asthma attacks. Preparations from this medicinal plant are useful and recommended even for pulmonary tuberculosis. Since the main active ingredient of sundew has an anti-spastic effect, it is worth trying to use it for gastric and intestinal diseases that cause spastic pain.

Use in homeopathy. The homeopathic remedy Drosera is traditionally prescribed for whooping cough. The main symptom in all this is considered a spasmodic cough, accompanied by chest pain and often vomiting. Dilutions from D to Dg are used. For whooping cough, some homeopaths believe that higher dilutions (D6-D 1 0 and above) are more effective. It will be necessary to try this under the supervision of a doctor. Dosages: 3-5 times every day for 3-10 (up to 15) drops.

Application in folk medicine.Sundew, sparkling in the sun, as if covered with transparent diamonds, cannot but attract attention. It was unknown to the old authors, since it was not used in Greece, and the doctors of the Middle Ages could only rely on their own experience. Arnoldus de Villanova of Barcelona was the first, according to oral tradition, to have taken up this medicinal plant, but his knowledge could not be disseminated in writing, since all his works were destroyed by the Inquisition. And only since modern times, as it is customary to call the 18th and 19th centuries, the use of sundew for coughing is approved by doctors and traditional medicine diligently uses this plant. This zeal initially caused distrust of sundew, but modern research has confirmed its positive effect on coughs. And if official medicine uses almost exclusively herbal products,

  • Sundew tea: 1 teaspoon of herb is poured into 1/4 liter of boiling water, infused for 10 minutes and filtered. Drink 2 cups of tea sweetened with honey in small sips every day (no more!).

The German National Health Service names spasmodic and reflex coughs as the area of ​​application for sundew. Sundew is not often mixed with plantain, thyme and fennel, taken in equal parts. Prepare, as mentioned above, at the rate of: 2 teaspoons of the mixture per 1/4 liter of tea.

Side effects. With the right dosage, sundew is safe to use, and overdosing can exacerbate a coughing fit. Chewing fresh leaves causes irritation of the oral mucosa, the stomach reacts to this with vomiting, and the intestines with diarrhea.
