Components such as phenolic acids, flavonoids, and flavonols, particularly anthocyanosides, present in blackberries work against the harmful oxygen-free molecules and counteract their action. This protective radical scavenging activity protects the body from a range of diseases caused as a consequence of oxidative damage which may be the underlying cause of many fatal conditions. Researcher Wang SY of Beltsville Agricultural Research Center in a study has concluded blackberries to have the third-highest ORAC – oxygen radical absorbance capacity (antioxidant capacity) fruit, following strawberries and black raspberries.

Anti-cancer Properties

Blackberry fruit is effective against the development of cancer including lung cancer, colon cancer, and esophageal cancer. The micro-nutrients present in blackberries exert a chemo-preventive effect and prevent the proliferation of malignant cells. Blackberry extracts inhibit carcinogenesis and associated cell signaling. It also possesses chemopreventive effects, according to a study published in Nutrition and Cancer by researchers of the National Institute for Occupational Safety and Health. A book named ‘Cancer Uncensored’ by Christopher C. Evans mentions that blackberries can initiate anti-cancer activity owing to the presence of anthocyanin in them.

Prevents Endothelial Dysfunction

Blackberries provide protection against endothelial dysfunction. Abnormal functioning of the inner lining of blood vessels chategorize it. As suggested by a study cited in Elsevier’s Life Science journal, they contain useful components such as cyanidin-3-O-glucoside. These fight the oxidative activity and help in normalizing multiple critical factors implicated in such conditions. It also helps in reducing DNA damage and guards against vascular failure.

Boosts Cognition

Blackberry also extends its beneficial effect in improving the cognitive functions of the body. A study conducted by Dr. Barbara Shukitt-Hale, et al., USDA-ARS Human Nutrition Research Center on Aging at Tufts University, Boston on aged rats in 2013 disclosed several things. The results suggest that the polyphenolic components present in blackberries help slow down the age-related decline in motor and cognitive activity attributing to their super antioxidant power. Regular consumption of blackberries may prove useful in enhancing memory performance and improving behavioral and neuronal functions.

Improves Digestion

The insoluble fiber in blackberries encourages easy and better absorption of water in the large intestine and adds bulk to the stools. This aids in regular bowel movements, freedom from constipation, and apt digestive health.

Use of Blackberry Leaves

Leaves of the blackberry plant have been found effective in curing diarrhea and dysentery since early times, and have also been a topic of interest for modern research. [1] This is attributed to the abundance of astringent tannins in the herb, which helps control such conditions in the digestive tract. Another benefit of astringent tannins in blackberry leaves is their healing effect on wounds.

The astringent qualities of blackberry leaf may also prove useful in soothing a sore throat and treating hemorrhoids.

Side Effects of Blackberry


If you are not allergic to berries, then blackberries are the fruit for you. However, some pieces of evidence have shown that the presence of tannins in blackberry may contribute to the development of tumors if consumed in high concentrations. The good news is that blackberry fruit has very small quantities of tannins which usually do show any detrimental effects.

  • Black tea leaf: Extra caution is advised regarding the intake of blackberry leaf tea or decoction. Consumption of large quantities of blackberry leaf tea elevates a number of tannins in the body tremendously and may cause stomach complications such as nausea and vomiting. Experts generally recommend the usage of milk in the preparation of blackberry leaf tea to neutralize the effect of tannins. People who are already suffering from cancer or have a previous history of such diseases should avoid the usage of tea made from blackberry leaves.
  • Blackberry root: Blackberry root is also a profuse source of tannins and is not recommended for individuals suffering from chronic gastrointestinal problems such as colitis.

Children under 24 months should not be given blackberry leaf tea. For older children and old people over the age of 65 years, it is recommended to consult a doctor for a correct prescription of blackberry leaf tea.

Blackberry leaf may result in allergic reactions ranging from mild to severe. An opinion from a medical expert is always recommended to discuss an individual’s existing symptoms, correct dosage, and the potential risks before considering blackberry leaf tea for therapeutic purposes so that any undesirable conditions are avoided. In case you notice any allergic reactions post the consumption of blackberry or blackberry leaf tea, consult a healthcare professional immediately.

Recipe for Blackberry freezer jam

Blackberry Jam



3 1/4 cups mashed blackberries

1/4 cup freshly squeezed lemon juice

1 box Sure-Jell Pectin

1 cup light corn syrup

4 1/2 cups granulated white sugar

Once all the pectin is mixed in, set a timer for 30 minutes, and give the fruit a stir every 7 to 10 minutes.

After the 30 minutes, stir in the corn syrup and then place the pot on the stove over medium heat. Stir in the sugar a little at a time and cook for about 5 minutes until the sugar is dissolved (it should be good to go when the jam reaches 100 degrees F or you can just rub it between your fingers to make sure you don’t feel any grains). If it is cooked longer it will be quite runny.
