In the United States, black currant (Ribes nigrum) have long been called the forbidden fruit. Farmers claimed the tart berries from Europe and Asia helped spread a fungus that destroyed pine trees.
Black currant has a high concentration of:
- vitamin C
- gamma-linolenic acid (GLA)
- polyphenolic substances
They use these berries in many healthy foods and beverages in the UK. Their tartness also lends itself to mixing with other fruits, especially in juices and jams.
In addition, people use all the plant from the leaves to the seeds for several purposes. The most popular form is its seed oil, but you can also make fresh or dried infusions and teas from the leaves of the plant.
However, people take black currant to help their blood flow, immune system, eye health, gut health, and kidney health. The extracts have shown to reduce the risk factors for metabolic disorders such as type 1 and type 2 diabetes.

Black currants have plenty of antioxidants and anthocyanins, besides vitamin C. These can help enhance your immune system, soothe the sore throats, and ease the symptoms of flu.
Black currant leaves also have a variety of qualities, such as antimicrobial, anti-inflammatory, antiviral, antitoxic, antiseptic, and anticancer properties. One study showed that black currant supplements enhanced immune response in people who were exercising regularly.
The supplements also helped them to train longer and harder. Another study in healthy older adults showed that the black currant seed oil boosted their immune system.

Black currants have a direct effect on the inflammatory response in your body. Its seed oil contains gamma-linolenic acid (GLA), an omega-6 fatty acid said to help relieve body inflammation.
The high content of GLA and anthocyanin may help to lower joint or muscle pain, stiffness, soreness, and damage. GLA supplements have been so effective in some studies that participants with rheumatoid arthritis might reduce their usual pain medication.

The GLA also helps the cells in your heart withstand damage and slows the clumping of platelets in your blood vessels. Furthermore, one study found that black currant powder increased heart blood flow and decreased the peripheral resistance.
Can Improve Eye Health

Studies have found that black currant may improve these eye functions such as visual field deterioration, visual fatigue, ability to adapt to the dark, and blood flow to the eyes.
