The European dewberry is not only a delicious forest berry, but also a plant whose various parts have long been used in traditional medicine. The ripe fruit contains vitamin C, and people eat them fresh or make them into juice, compotes, jellies and syrups. The leaves were traditionally brewed as tea, the stems were used to make decoctions, and the roots for external rubs.

What are the benefits of the European dewberry, how do dietary uses of the berries differ from using herbal raw materials, how do you properly harvest the fruit, and who should exercise caution? Let's break down the plant's properties, well-known traditional recipes and the rules for safe use.

## What are the benefits of the European dewberry?

The main dietary value of the European dewberry comes from its fruit. Phytotherapy reference books note that it contains vitamin C, and the berries themselves have a pleasant taste and high qualities among wild berries.

However, folk medicine used more than just the fruit. Traditional descriptions include recipes featuring leaves, stems and roots. Each part of the plant had its own purpose.

It is important to distinguish between eating berries normally and using concentrated herbal preparations. These are different ways of using the plant, and they should be treated differently.

**Berries: vitamin C and dietary use.**

Ripe European dewberry fruit is juicy, dark, with a characteristic bluish bloom. They contain vitamin C and are suitable for a variety of homemade preserves.

The berries are consumed:
- fresh, immediately after picking;
- as juice;
- in compotes;
- for making jellies and marmalade;
- for making syrups;
- as raw material for wine and liqueur.

Including ripe dewberries in your diet allows you to add variety to your meals and get vitamin C from a natural food product.

At the same time, the vitamin content does not mean that the berries can independently cure colds, stomach ailments or other health issues. The nutritional value of the fruit and the medicinal action of herbal preparations are not the same thing.

**Leaves: traditional herbal tea.**

Old phytotherapeutic descriptions mention tea made from the leaves of the dewberry and other representatives of the *Rubus* genus. Such a drink was traditionally used for colds and gastrointestinal discomfort.

This is one of the well-known traditional ways of using the plant. However, information about traditional use does not allow us to automatically transfer recipes for other *Rubus* species to the European dewberry, or consider such tea a proven medicine.

**Stems: traditional use for stomach complaints.**

Old herbals describe an aqueous decoction of European dewberry stems. It was traditionally used for catarrh of the stomach.

We are talking about a historical folk recipe. It does not prove the plant's effectiveness against gastritis, stomach ulcers and other digestive system disorders. You should not independently replace a medical examination and prescribed treatment with such a decoction.

**Roots: external use.**

Folk descriptions mention a tincture of European dewberry roots in vodka. It was used externally for rubbing in cases of rheumatism. It is important not to confuse this method with taking the tincture internally. Moreover, historical use does not confirm the effectiveness of such a remedy for rheumatism and other joint diseases. For persistent pain, you need to find out the cause of the ailment rather than limiting yourself to homemade rubs.

## European dewberry in folk medicine: what did our ancestors use?

Folk phytotherapy used practically all the main parts of the plant. At the same time, the methods of use varied significantly. The most widespread and understandable remains the dietary use of the fruit. Ripe berries were eaten fresh, juiced, and made into compotes, syrups, jellies and marmalade. Older reference books also describe the following methods:

- **Stems.** An aqueous decoction was made from them, which was traditionally used for catarrh of the stomach.
- **Leaves.** They were used to make herbal tea for colds and gastrointestinal discomfort. These recipes also mention other species of the *Rubus* genus.
- **Roots.** A vodka tincture was made from them for external use in cases of rheumatism.
- **Fruit.** They were used not only for food, but also for making juice, syrup and other drinks.

Dewberry juice for hoarseness is mentioned separately in folk practice. This is a traditional method of using the berries as food, not a proven method for treating throat diseases. All the listed methods belong to folk experience. They let us understand how the plant was used in the past, but they do not establish the effectiveness and safety of each recipe.

You should be especially careful with tinctures, concentrated decoctions and other preparations made from leaves, stems and roots. They cannot be considered harmless just because the raw material is of natural origin.

If you are considering using herbal remedies for a chronic condition, discuss it with your doctor beforehand. Such remedies should not replace prescribed treatment.

### Can you eat European dewberry when you have a cold?

Yes, ripe berries can be eaten as a regular food product if you have no individual intolerance. Old herbals also describe making tea from dewberry leaves and other *Rubus* species for cold-related discomfort. Dewberry juice was traditionally used for hoarseness.

However, you must understand the difference between a dietary drink and a medicinal product. Berries and juice can be included in the diet, but they do not replace the treatment of throat and respiratory tract diseases.

If you have a high fever, difficulty breathing and a marked deterioration in your well-being, you must consult a doctor.

## How to properly brew European dewberry?

Here, the most important thing is to decide what exactly you want to make: a berry drink or a traditional herbal tea made from leaves.

**Berry drink.**

Ripe European dewberry fruit is used for food fresh, as well as for making compotes, juices, jellies and syrups. This is the most straightforward way to consume the fruit described in reference books.

You should not confuse such a drink with a medicinal infusion. For regular dietary use, the berries can be added to compotes and other fruit drinks.

**Leaf tea.**

Old phytotherapy describes making tea from the leaves of the dewberry and other representatives of the *Rubus* genus. It was traditionally used for cold and gastrointestinal discomfort.

However, available reference descriptions do not provide an exact recipe specifically for European dewberry leaves: the proportions of raw material and water, preparation time and medicinal dosage have not been established. Therefore, giving arbitrary amounts of leaves per cup of water would be incorrect.

If the goal is to make a medicinal drink specifically, you should not choose the strength and duration of use on your own. This is especially important for chronic conditions and constant medication use.

**Stem decoction.**

Old herbals mention an aqueous decoction of European dewberry stems for stomach catarrh. But the exact preparation technology is not given in the description. Therefore, this recipe should not be turned into a home treatment regimen by arbitrarily choosing the amount of raw material and boiling time.

My practical advice: for everyday consumption, give preference to ripe berries and ordinary culinary preserves. Leaves, stems and roots are different plant materials whose use requires special attention to safety.

## How to harvest fruit and prepare European dewberry?

The European dewberry ripens gradually. On a single bush, you can see green, reddening and fully ripe berries at the same time. Therefore, harvesting the fruit is done in several passes. According to botanical reference books, the harvesting period falls between July and September. At this time, mature blue-black fruit with a characteristic bluish bloom appears on the bushes. When harvesting, you should follow a few rules.

1. **Choose ripe berries.** Fully matured fruit has a dark color, becomes juicy and acquires a characteristic bluish bloom.
2. **Inspect each fruit.** Unspoiled berries without signs of rot are suitable for dietary consumption.
3. **Identify the plant correctly.** Make sure you are picking the European dewberry and not another similar species.
4. **Consider the harvesting location.** Do not harvest plants where there is a risk of pollution.
5. **Protect your hands.** The stems, leaf stalks and other parts of the plant are covered with prickles.

The European dewberry has features that help distinguish it from other members of the genus. A bluish bloom is noticeable on the stems, the prickles are bristly, and the fruit is covered with a bluish waxy coating.

If you are not sure about identifying the plant, it is better to skip harvesting it yourself. A mistake in recognizing wild species can lead to using unsuitable raw material.

**How to use harvested berries?**

Fresh fruit can be eaten immediately after picking. If there are many berries, they are processed into homemade preserves.

Reference literature lists the following options:
- juice;
- compote;
- syrup;
- jelly;
- marmalade;
- wine;
- liqueur.

The dewberry is suitable not only for fresh consumption, but also for a variety of homemade preserves.

Leaves, stems and roots should be considered separately from edible fruit. The mere fact of their traditional use does not mean that any harvested raw material can be safely used to prepare medicines.

When harvesting, it is important to monitor the cleanliness of the plant material and not use raw materials of unknown origin.

## How to find European dewberry abroad

Outside of Russia, the European dewberry can be found under different names. To avoid confusing it with other types of blackberries and raspberries, pay attention to the Latin name.

**What the plant is called:**
- USA: European dewberry, dewberry, blue bramble.
- Germany: Kratzbeere, Acker-Brombeere, bereifte Brombeere.
- France: ronce bleue, ronce bleuâtre, petite ronce.
- Latin name: *Rubus caesius L.*

**What form it is sold in:**
- Fruit — fresh or frozen, less often dried.
- Leaves — loose dried or in tea bags.
- Tinctures — from specialized herb sellers.
- Capsules and tablets are rare.

**Where to look:**
- In the USA — health food stores, tea shops and herbal stores.
- In Germany — Reformhaus, tea shops and Apotheke.
- In France — herboristeries, magasins bio and tea shops.
- On the internet — from specialized sellers of medicinal plant raw materials.

**What to check on the package:**
- The Latin name *Rubus caesius L.*, not just blackberry or mûre.
- The part of the plant used: fruit, leaves or roots.
- Ingredients, country of origin, shelf life, batch number and manufacturer information.

Important: the regular blackberry (*Rubus fruticosus agg.*) and raspberry leaf (*Rubus idaeus*) are different plants. In the USA, herbal supplements are regulated as dietary supplements, while in Germany and France, requirements depend on whether the product is sold as food or medicine.

## European dewberry: contraindications and precautions

Ripe berries and concentrated herbal preparations require different approaches. Regular consumption of fruit as food cannot be equated with taking infusions, decoctions and tinctures. Caution is required for the medicinal use of leaves, stems and roots. The safety of such preparations and appropriate dosages have not been sufficiently studied.

**Allergies.**

If you have a known allergy to blackberries or other plants of the Rosaceae family, you must avoid the product that causes the reaction. Allergic manifestations can affect the skin and other body systems.

If an undesirable reaction occurs after consuming berries or an herbal preparation, stop using the remedy.

**Gastrointestinal tract diseases.**

Leaves and roots contain tannins. Concentrated preparations in sensitive people can cause nausea, vomiting, abdominal discomfort or constipation. If you have chronic digestive system diseases, consult a doctor before using such remedies.

**Pregnancy and breastfeeding.**

The safety of medicinal amounts of plant raw materials during pregnancy and breastfeeding has not been sufficiently studied.

Therefore, infusions, decoctions and concentrated extracts should not be used during this period without consulting a doctor. Ordinary dietary consumption of ripe berries is different from using herbal preparations in medicinal amounts.

**Childhood.**

There is insufficient data on the safety and dosages of medicinal uses of European dewberry leaves and roots. Children should not be given concentrated supplements, tinctures and strong herbal teas on their own. The possibility of using such remedies should be discussed with a pediatrician.

**Taking medications.**

There is insufficient reliable clinical data on the interaction of the European dewberry with medications.

Tannins can reduce the absorption of certain substances, including iron. Therefore, when using herbal preparations, it is necessary to take into account their possible impact on the assimilation of simultaneously taken remedies.

A separate warning applies to people taking warfarin, digoxin and chemotherapy drugs. This is not a specific established interaction with the European dewberry per se, but a general precaution when using herbal remedies alongside such therapy.

Before using infusions, decoctions and other herbal preparations, you must consult your doctor or pharmacist.

If you have diabetes, high blood pressure, heart disease, thyroid disorders and other chronic conditions, dietary consumption of berries should not be confused with treatment. If you are considering herbal preparations in addition to prescribed therapy, coordinate their use with a specialist beforehand. Do not stop taking prescribed medications on your own.

**What symptoms cannot be ignored?**

With persistent vomiting, severe abdominal pain, jaundice, rash, difficulty breathing or unusual bleeding, you must stop using the herbal preparation and seek medical help. Difficulty breathing and unusual bleeding require particularly urgent medical evaluation. Do not try to cope with such manifestations using home remedies.

## When you need a doctor

Even wild plants require a sensible attitude. Natural origin does not guarantee the absence of side effects. This is especially true for concentrated extracts, tinctures and decoctions. A medical consultation is necessary in the following situations:

- An allergic reaction appeared after consuming berries or an herbal preparation.
- Nausea, vomiting, abdominal pain or other persistent digestive disorders occurred.
- Jaundice, severe abdominal pain or unusual bleeding appeared.
- A rash or difficulty breathing occurred. Urgent medical care is necessary for difficulty breathing.
- You are pregnant or breastfeeding and are considering using dewberry in medicinal amounts.
- You want to use leaves or roots to prepare home medicines for a child.
- You are constantly taking medications or undergoing treatment for a chronic condition.
- You plan to combine herbal remedies with medications for which dosage accuracy is especially important.

You should not independently treat prolonged digestive disorders, joint pain and other symptoms requiring diagnosis with dewberry decoctions. First, you need to establish the cause of the ailment.

When harvesting wild plants yourself, there is also the risk of errors in species identification and contamination of plant material. Do not use raw materials of unknown origin to prepare home remedies.

## From the author

In my work, I always pay attention to an important distinction: it is one thing for a plant to be part of daily nutrition, and quite another to be an herbal preparation attributed with medicinal properties.

The European dewberry is a good example of this distinction. Its ripe berries contain vitamin C, have a pleasant taste and are suitable for a variety of homemade preserves. This is a clear and traditional food use.

The situation is different with leaves, stems and roots. Their use is described in old phytotherapeutic reference books, but a historical recipe does not yet mean that its exact dosage, effectiveness and safety are known.

I consider it important not to attribute extraordinary medicinal properties to wild plants, while at the same time not forgetting their nutritional value and place in folk tradition. A sensible approach begins with correct plant identification, understanding the purpose of its use, and respecting the limitations of plant raw materials.

## From the editorial staff
