Furthermore, blackberry contains a variety of minerals such as potassium, copper, calcium, magnesium and zinc. The sweet taste of this fruit is due to the presence of natural sugars in it such as fructose, glucose and sucrose.

Rich in Phenolic Acids & Flavonoids

Phenolic acids are plant metabolites that fight against oxidative stress and reduces the risk of diseases associated with it. Various phenolic acids have been identified in blackberry, these include:


Flavonoids present in blackberry include:


These flavonoids protect against various diseases such as cardiovascular disease, diabetes, high cholesterol levels and so on. The presence of so many health-promoting compounds in blackberry makes is a therapeutic fruit.

Rich in Carotenoids

Carotenoids are natural pigments that occur in blackberries. These carotenoids possess immune-boosting properties and thus, they keep infections at bay. Carotenoids present in blackberries include:


Research observed that the content of these carotenoids decreased in over-ripened blackberries. In order to reap the health benefits of these carotenoids, one should consume fully ripe blackberries.

Rich in Antioxidants

Blackberries are a great source of antioxidants. These antioxidant have strong radical scavenging property, thus it protects against a number of diseases. Blackberry contains high concentration of anthocyanins, carotenoids, phenolic compounds and ascorbic acid that possess antioxidant property. However, it is noted that the concentration of some antioxidants such as vitamin C decreases in over-ripe blackberries. Therefore, it is very important to consume blackberries in their ripe stage.

Therapeutic Advantages

Blackberry has a huge name in the clinical setting and many scientific observations have found positive effect of blackberry on overall health. Here is detailed information about therapeutic benefits of blackberry:

Type 2 Diabetes Mellitus

It has been claimed by many researches that blackberry is an anti-diabetic agent that helps in lowering plasma glucose level in individuals with type 2 diabetes mellitus. Individuals with diabetes usually have high levels of oxidative stress. Research has found that blackberry is extremely rich in antioxidants that scavenge free radicals and reduce the levels of oxidative stress. This further helps to prevent sudden spike in the plasma glucose levels and keeps it under control.

Several scientific observations even found that blackberry extracts play a beneficial role in delaying the onset of diabetic complications, especially diabetic neuropathy (damage to the nerves). Such a plasma glucose lowering effect of blackberry is attributed to the presence of ANTHOCYANINS, ELLAGIC ACID, ELLAGITANNINS and FLAVONOLS. These bioactive compounds inhibit the accumulation of SORBITOL and are able to relieve diabetic complications. Therefore, eating fresh blackberries may help in the management of type 2 diabetes mellitus.

Antioxidants Properties

A very interesting research published in 2008 observed the effects of blackberry on antioxidant status of the body. Research showed that drinking blackberry juice prepared with water or defatted milk increased the level of ascorbic acid in the body, which is a potent antioxidant. Individuals who consumed such a juice had a higher antioxidant capacity. Such an effect was attributed to the presence of anthocyanins in blackberries. Blackberry juice further increased the level of antioxidant enzyme in the body such as catalase. All these properties make blackberry juice an excellent immune-boosting beverage.

Anxiety Disorders

Blackberry extracts works like an anti-anxiety agent that helps one to relax and calm down and thus, fights anxiety. A research showed that as the dose of blackberry extract increased, its anti-anxiety effect also increased and vice versa. Thus, consuming blackberries can help individuals to overcome anxiety disorders and depression. Furthermore, blackberries also increased mental alertness to some extent. Besides this, blackberry extract did not have any sedative effect and was not able to induce sleep. As compared to anti-anxiety medications, the best part about blackberries is that it comes without any side effects. Anti-anxiety medications may lead to addiction and side effects but blackberry is completely safe

Prevents Food Borne Infections

Research examined an effective role of blackberry against the inhibition of food borne bacterial pathogens such as E. coli, Salmonella Typhimurium and L. monocytogenes. Furthermore, blackberry also improved the growth of beneficial bacteria in the gut. A study observed that a small amount of blackberry juice can inhibit the growth of foodborne pathogens and stimulate the growth of gut-healthy bacteria. Such an inhibitory effect of blackberry is due to the presence of polyphenolic components in them. Out of all the polyphenolic compounds, ellagitannins had the strongest inhibitory activity against foodborne pathogens. These polyphenolic components bind to the outer membrane of bacteria and inactivate their harmful mechanism. In addition to this, blackberry juice also stimulates the growth of probiotic bacteria and creates a healthy environment in the gut.

Prevents Gastric Inflammation

Gastric inflammation may increase the risk of gastric ulcers and gastritis. Ellagitannins and ellagic acid conjugates are two powerful polyphenols that help in reducing gastric inflammation and are present in very few fruits and vegetables. Blackberry is one such fruit that contains significant amount of ellagitannins and ellagic acid. These polyphenols have great anti-inflammatory properties.

Research has showed that blackberries are capable of protecting the stomach against gastric lesions. As compared to raspberry, the anti-ulcer effect of blackberry was higher. Consuming blackberry also increases the level of antioxidant enzymes present in the body such as superoxide dismutase and catalase. These antioxidant enzymes further protected the inner lining of the stomach and reduced inflammation.

In other words, it can be said that blackberry inhibits the action of Helicobacter pylori (causes gastric ulcer) and reactive oxygen species in inflammatory conditions. Such an immunomodulatory effect of blackberry can protect against peptic ulcer.


Research has found that blackberry is a very effective remedy in the treatment of diarrhea. The anti-diarrheal effects of blackberry are attributed to the presence of volatile oils, tannins, organic acid and ascorbic acids. All these health-promoting components soothe the inflamed mucosa and help in quick healing.

Relaxant Properties

Several scientific studies have found that blackberry has medicinal properties that help to relieve abdominal pain and treats gut infections effectively. Research found that blackberry expels parasitic worms out of the body and thus, protects the body against infection (anthelminitic activity). Such an activity in blackberry is attributed to the presence of phytochemicals such as flavonoids, tannins, saponins and sesquiterpenes. These phytochemicals have properties similar to anthelminitic drugs, which help in the treatment of gut problems caused by parasites. It has also shown to relieve pain and it works similar to an anti-spasmodic drug. Blackberry helps to relax spontaneous contractions and thus, has a relaxing effect on the gut. It also throws out all the toxins from the body and thus, protects the gut.


Blackberry is an abundant source of polyphenols, flavonoids and antioxidants that prevents oxidative stress by scavenging the harmful free radicals.  Such a property of blackberry helps to kill the cancer cells and prevents their spread to other healthy cells of the body. It also reduces the pro-inflammatory markers and overall inflammation.

Research has showed that individuals with cancer who consumed anthocyanin rich fruits had reduced oxidative damage to the DNA and improved the status of natural antioxidant enzyme system in the body. In addition to this, blackberries contain approximately 80% moisture. Removal of this moisture that is seen in case of dried blackberries may lead to loss of some important phytochemicals. Therefore, individuals with cancer should consume whole and fresh berries in order to reap its benefits.

Visual appearance and color of blackberry is an important parameter, which you must keep in mind while purchasing. Darker the color, higher is the concentration of bioactive compounds such as anthocyanins.

On ripening, the content of anthocyanins increases tremendously. Such an increase also causes the color of blackberries to change from green to purplish-black. In addition to this, unripe berries have a lower potential to scavenge free radicals and their antioxidative potential is poor.
