Common Barberry: Beneficial Properties and Uses

Dr. Boris Wydoff

Common barberry (*Berberis vulgaris*) is a thorny shrub with bright red, sour berries. In herbal medicine, the fruits, leaves, bark and roots of the plant are used. The berries contain vitamin C, organic acids and pectins, while the roots and bark are rich in berberine. Barberry has traditionally been used to improve appetite and bile secretion. However, preparations made from different parts of the plant have different properties and limitations.

What kind of plant is it?

Common barberry belongs to the Barberry family. It is a perennial, highly branched shrub that usually grows up to 1.5–2 meters. It can be easily recognized by its three-part thorns, small leaves and clusters of yellow flowers.

The leaves grow in bunches. They are dark green, sometimes with a reddish tint and a waxy coating. The edges of the leaf blades are finely serrated. The flowers are small, light yellow and bell-shaped. They are gathered in drooping clusters. The shrub blooms in May and June.

By autumn, elongated red berries appear on the branches. They ripen in September and October. The fruits taste sour, sometimes with a noticeable astringency. Depending on growing conditions, the berries may remain on the bush even in winter.

In nature, barberry grows in steppe and forest-steppe regions, on hillsides, along ravines and at forest edges. It is widespread in the European part of Russia, the Caucasus and Transcaucasia. The shrub is also cultivated in gardens and parks.

Barberry is valued not only for its fruits. It is used in ornamental gardening, including for creating hedges. During flowering, the plant attracts pollinating insects.

What substances are found in its fruits?

The chemical composition of barberry depends on the part of the plant. The berries differ from the roots and bark both in composition and in the content of biologically active substances.

The fruits contain:

• vitamin C (ascorbic acid);
• organic acids, including malic, citric and tartaric acids;
• sugars;
• pectin substances;
• carotene and carotenoids;
• rutin and other flavonoids;
• tannins;
• anthocyanins.

The sugar content in berries is approximately 4–12%, while organic acids account for 3–7%. The fruits also contain vitamin C. One botanical reference book gives a value of about 150 mg per 100 g of raw material. The actual content depends on ripeness and growing conditions.

Leaves contain vitamin C, vitamin E, rutin, carotene, organic acids, tannins and resinous substances. They also contain essential oil and carotenoids.

Roots and bark are distinguished by their high alkaloid content. The main one is berberine. In addition to it, the roots contain palmatine, columbamine, jatrorrhizine, berberrubine and other compounds. Root bark is especially rich in alkaloids.

Berberine has pronounced biological activity. It affects bile secretion, uterine contractions and blood pressure. This is why preparations made from roots and bark require special caution. It is important to understand that the presence of beneficial substances in a plant does not by itself mean that a homemade infusion or decoction has proven therapeutic effectiveness.

What are the benefits of this plant and where is it used?

In herbal medicine, different parts of barberry are used for different purposes. The fruits are mainly considered food and vitamin raw material. Leaves, bark and roots are used to make medicinal preparations.

For digestion and appetite

Sour barberry berries have traditionally been used to stimulate appetite. Their taste is associated with the presence of organic acids. The fruits are also used as food to help quench thirst.

European herbal books describe the use of berries to support digestive activity. In traditional practice, they were used when appetite was reduced and for some digestive complaints. However, sour fruits are not suitable for everyone. With increased stomach acidity, consuming barberry may be undesirable.

For the bile system

One of the best-known areas of medical use of barberry is related to bile secretion. According to herbal medicine references, berberine stimulates bile production. Plant preparations have traditionally been used for certain disorders of the bile ducts.

Barberry tincture has antispasmodic properties affecting the gallbladder. Experimental studies have noted a decrease in its tone and changes in contraction rhythm. These effects are associated with improved bile flow.

In medical practice, barberry preparations are described as choleretic agents for some diseases of the liver and biliary system. However, their use depends on the diagnosis and nature of the condition. With gallstone disease, independent use of herbal remedies may be unsafe.

For metabolism and general nutrition

Barberry fruits contain vitamin C, carotene and other biologically active substances. They contain pectins and organic acids. In traditional herbal practice, berries were considered vitamin-rich food material. They were included in the diet to diversify nutrition and to prepare drinks and desserts. However, barberry cannot be considered a replacement for a balanced diet or prescribed vitamin preparations. The vitamin content of fruits changes depending on the variety, ripeness and storage method.

For the urinary system

Older herbal books describe the diuretic effect of barberry. In particular, its influence on urine production is mentioned.

However, information about traditional use does not mean that berries or decoctions are suitable for self-treatment of kidney diseases. If there are problems with urination, pain or changes in urine color, the cause of symptoms should be determined.

For women’s health

Medical references describe the use of barberry leaf tincture in obstetric and gynecological practice. Traditionally, it was used as a supportive remedy for some types of uterine bleeding.

At the same time, berberine can increase uterine contractions. This property is important for safety. Barberry preparations should not be used independently for bleeding, menstrual disorders or other gynecological problems.

During pregnancy, medicinal use of barberry is contraindicated.

How is it used in everyday life?

Barberry is best known for its berries. They are used in cooking, while the leaves and other parts of the plant have a history of medicinal use.

Berries for drinks and dishes

Ripe fruits have a characteristic sour taste. They are suitable for making:

• jam and marmalade;
• jelly and syrups;
• fruit jelly drinks;
• compotes and fruit drinks;
• sauces and seasonings for meat;
• confectionery products.

Dried berries are used as a seasoning. In Caucasian and Central Asian cuisine, they are added to meat dishes and pilaf. The acidity of the fruits gives dishes a special flavor. Berries are also used to make juices and other food products. Due to their strong taste, they are sometimes used instead of lemon in cooking.

How to brew barberry correctly?

In traditional culinary practice, berries are added to tea to give it a slightly sour taste. They are also used together with other food ingredients to prepare hot drinks.

However, medicinal dosages and exact proportions for preparing a medicinal berry infusion at home are not universal. They depend on the raw material and the intended purpose. Dosages of pharmaceutical berberine preparations should not be transferred to homemade decoctions. The concentration of active substances in them is unpredictable.

Medicinal preparations

In pharmaceutical practice, barberry is used to obtain berberine-based preparations. References mention berberine bisulfate and leaf tincture. Certain preparations from bark and roots have historically been used as part of medicines for the biliary system. Such forms differ in composition and concentration of active substances. Therefore, their use should follow the instructions for the specific preparation and recommendations of a doctor.

How to collect and store its fruits?

Different parts of the shrub are collected for preparation. The harvesting period depends on which raw material is needed.

Berries are collected in autumn after ripening. This is usually September and October. The fruits should have developed their characteristic red color. They can be used fresh, dried or frozen.

When collecting, it is important to select whole berries without signs of rot or mold. Unripe green fruits are not suitable for eating: they contain berberine and may be toxic.

Leaves are collected during the growing season. Healthy leaves without signs of pests or disease are used as medicinal raw material.

Bark and young branches are traditionally collected in autumn. Roots containing significant amounts of alkaloids are also mentioned for medicinal purposes.

Independent harvesting of roots and bark for preparing medicinal products is undesirable. The berberine content in such raw material can vary significantly.

Berries can be dried in a well-ventilated room or in a suitable dryer. Finished raw material should be stored in a dry place protected from moisture and direct sunlight. Clean containers with tightly closing lids are suitable for storage.

Dried fruits should be checked periodically. If mold, unusual odor or signs of moisture appear, they should not be used.

How to distinguish edible berries from unripe ones?

When collecting barberry, it is important to consider the degree of fruit ripeness.

Ripe common barberry berries have an elongated shape and red color. Their taste is sour, sometimes astringent. Depending on growing conditions, they may remain on the bush until winter.

Green fruits have an unripe color. They contain berberine and are not suitable for consumption. Do not taste unknown berries only because they look similar to barberry.

Special care should be taken when collecting wild plants. Some other barberry species may have different fruit colors. Therefore, the plant should be identified by a combination of characteristics, not only by the color of the berries.

How to find common barberry abroad

If you are looking for common barberry in the USA or Europe, it is important to know its names in local languages and pay attention to which part of the plant is being sold.

How barberry is called in different countries:

• USA: common barberry or European barberry.
• Germany: Berberitze or Sauerdorn.
• France: épine-vinette.
• Latin name: *Berberis vulgaris*.

Forms in which it is sold:

• Dried berries (fruits) — usually sold by weight as a food product or for fruit tea.
• Root and root bark — sold by weight, as liquid tinctures and extracts, as well as in capsules.
• Tea bags — available for sale, but the composition should be checked. The name “barberry tea” does not indicate which part of the plant was used.

Where to look:

• In the USA — in herbal and health food stores, as well as online stores.
• In Germany — in pharmacies (Apotheken), natural product stores (Reformhäuser), tea shops and online.
• In France — in herbal medicine stores (herboristeries), pharmacies, organic stores and online.

The range depends on the store.

What to check on the package:

• The Latin name *Berberis vulgaris*, not just barberry or berberine.
• The exact plant part: fruits, root or root bark.
• The purpose of the tea: food product or medicinal product.
• The presence of an organic certificate, if this is important to you. The word “organic” alone does not confirm either the plant part or the medicinal status of the product.

Consider the regulations of your country. In the USA, dietary supplements are regulated but do not receive FDA approval before sale for safety and effectiveness. In Germany, if you need medicinal tea, ask a pharmacy about the availability of Arzneitee: ordinary food tea and medicinal tea belong to different categories.

Contraindications and precautions when using it

Barberry contains biologically active substances that may affect the work of different organs. Special attention is required for preparations from roots and bark, which are rich in berberine.

Main contraindications and limitations:

• Pregnancy and breastfeeding. Medicinal use of barberry and berberine should be avoided. The plant may stimulate uterine contractions. Berberine exposure is also associated with the risk of increased bilirubin levels in infants.
• Allergy. If there is a known allergic reaction to barberry, it should not be used.
• Low blood pressure. Berberine may lower blood pressure, so plant preparations require prior consultation.
• Heart rhythm disorders. Medicinal use should be discussed with a doctor in cases of arrhythmia.
• Increased blood clotting and circulation disorders. Older references do not recommend barberry fruits and preparations for increased blood clotting and thrombophlebitis.
• Increased stomach acidity. Sour berries may not be suitable for people with such disorders.
• Taking medications. Berberine may affect the concentration of certain medicines in the blood.

Drug interactions require special attention. Berberine may increase the concentration of cyclosporine and tacrolimus. It also affects the activity of enzymes involved in drug metabolism, particularly CYP2D6, CYP2C9 and CYP3A4.

Caution is needed when combining barberry with blood sugar-lowering medications, warfarin and immunosuppressants. Possible interactions depend on the specific medicine and its dose.

When taking medicinal barberry preparations, nausea, abdominal discomfort, diarrhea, constipation and vomiting may occur. Sometimes dizziness, skin rash and fainting episodes are noted. With significant overdose, severe lowering of blood pressure, slowed heart rate and breathing problems are possible.

Eating ripe berries as food should not be equated with taking concentrated extracts. However, even food products should be consumed according to individual tolerance.

When a doctor is needed

Barberry does not replace diagnosis or prescribed treatment. If abdominal pain, nausea, changes in urine color, yellowing of the skin or digestive problems appear, consult a doctor.

It is especially important to seek medical advice with chronic diseases of the liver, gallbladder, kidneys and cardiovascular system. Herbal preparations should not be selected independently in such cases.

Before using medicinal products based on barberry, discuss their compatibility with your current medications. This is especially important when using medicines that affect blood clotting, blood sugar levels and immune system function.

Children should not be given berberine preparations without specialist advice. For infants, especially premature babies and newborns with jaundice, such preparations pose a particular risk.

If severe weakness, repeated vomiting, severe diarrhea, dizziness or fainting occurs after consuming barberry, medical help is required. If an overdose is suspected, seek medical advice immediately.
