Not only can you enjoy this flavorful berry all on its own, but it can also make a delicious addition to everything from baked goods to glazes and more. For even more added convenience, you can also pop a quick capsule of black currant oil to get an instant megadose of its many health benefits.

Whether you’re just hearing of black currants for the first time or they’ve been a longtime favorite in your household, these tart berries are high in health benefits and can be a nutritious addition to any diet.

Black Currant Benefits

1. Rich in Anthocyanins

The deep purple pigment of the black currant is attributed to its high anthocyanin content. Anthocyanins are plant pigments that produce a red, purple or blue hue depending on their pH.

Black currants contain a good variety of different anthocyanins, with some studies showing that they contain up to 15 unique types.

In addition to their role as a plant pigment, anthocyanins also possess many health-promoting properties. Research has shown that anthocyanins may play a role in cancer prevention, heart health, obesity and even diabetes.

They also act as antioxidants, which are compounds that neutralize harmful free radicals to prevent cell damage as well as chronic disease.

In addition to black currants, other anthocyanin-rich foods include berries, eggplant, red cabbage and grapes. Including a good amount of these foods in your diet can have a lasting impact on your health.

2. Helps Reduce Cancer Growth

One of the most impressive benefits of the black currant plant is its powerful effect on cancer. Thanks to its high anthocyanin content, some research has found that black currant extract may help slow the growth of cancer.

In one test-tube study conducted by Northeastern Ohio Universities Colleges of Medicine and Pharmacy, black currant extract was shown to help inhibit the growth of liver cancer cells. Another study out of Japan found that black currant extract blocked the spread of breast and endometrial cancer cells.

Other research published in the Journal of Medicinal Food has shown that black currant extract may also be effective in killing off stomach and esophageal cancer cells.

3. Promotes Eye Health

Glaucoma is a group of eye diseases that can cause blurred and distorted vision and may even lead to blindness. This is typically a result of damage to the optic nerve, the nerve that connects the brain to the eyes.

Some studies show that the compounds found in black currants could help prevent glaucoma and promote the health of your eyes.

In one study conducted by Sapporo Medical University School of Medicine’s Department of Ophthalmology in Japan and published in the Journal of Ocular Pharmacology and Therapeutics, supplementing glaucoma patients with black currant extract was shown to decrease levels of endothelin-1, a type of hormone that is thought to contribute to the development of glaucoma.

Another two-year, randomized, placebo-controlled study, again conducted at the Sapporo Medical University School of Medicine, found that black currant anthocyanins helped reduce vision loss and improved blood flow to the eyes in patients with glaucoma.

When used in combination with traditional treatments, black currant may be effective in promoting eye health and preventing vision loss.

4. Boosts Immunity

Black currant is bursting with vitamin C. In fact, just one cup of raw black currants can provide triple the amount you need for the entire day.

Vitamin C is well-known for its immune-enhancing properties. Studies show that vitamin C can shorten the duration of respiratory tract infections and protect against malaria, pneumonia and diarrhea infections, among others.

One review from the Department of Public Health at the University of Helsinki in Finland comprised 12 studies and found that vitamin C supplementation cut common cold incidence by up to 91 percent and slashed the incidence of pneumonia by 80 percent to 100 percent.

Vitamin C also acts as an antioxidant, which can help prevent damage to tissues caused by harmful free radicals and may even reduce the risk of cancer, heart disease and stroke.

For best results, pair black currant with other high vitamin C foods, such as fruits and vegetables, to keep your immune system strong.

5. Protects Against Pathogens

In addition to its powerful abilities as an antioxidant, black currant also contains antimicrobial properties that could help protect against harmful bacteria and viruses.

A 2012 study in Japan published in Microbiology and Immunology showed that black currant extract with a concentration of less than 1 percent was able to block the growth of several strains of viruses including those responsible for adenovirus and influenza by over 50 percent. An extract of 10 percent concentration was able to block 95 percent of these viruses from sticking to cell surfaces.

Another study from the Department of Microbiology at Asahikawa Medical College in Japan demonstrated that treating strains of influenza with a concentrated amount of black currant extract was able to completely suppress virus growth.

Other research has found that blackcurrant oil may be effective against H. pylori, a type of bacteria that can cause stomach ulcers, abdominal pain and nausea.

Black currant may also be helpful in treating other types of illnesses caused by bacterial infections, such as whooping cough.

6. May Prevent Herpes Outbreaks

Herpes is a common viral infection that affects millions of people worldwide. Symptoms can vary, causing fever blisters on or around the mouth in some people and painful, itchy genital sores in others.

Some studies show that the compounds found in black currant may help kill off the virus that causes both oral and genital herpes.

A study published in Phytotherapy Research showed that black currant extract stopped the herpes virus from adhering to cells and prevented the spread of the virus.

Coupled with traditional treatments and other natural remedies like L-lysine and zinc, black currant may be a useful addition to the diet to help prevent herpes outbreaks.

Black Currant History

Black currant has a rich history as a popular natural remedy and has been used for everything from treating gout to relieving PMS symptoms.

In the 1800s, black currant was extremely popular in the United States. In fact, in the 1920 census it was estimated that United States farmers were growing 7,400 acres of currants and gooseberries. However, many Americans today have never tried, let alone heard of, the black currant.

This is because it was later discovered that black currants were responsible for the spread of white pine blister rust, a type of fungus that began gradually killing off white pine trees. This became a major problem, as white pine trees were an essential component of the lumber industry.

By the 1920s, millions of white pine trees had been decimated by white pine blister rust, leading the federal government to ban and begin eradicating the black currant. 

Today, most white pine trees have been bred to resist the effects of white pine blister rust. Commercial growth of black currants is no longer banned at the federal level, although several states do still have regulations in place restricting growth.

In Europe, black currants have retained their popularity over the years. In fact, a black currant juice called Ribena was even given to children during World War II to prevent vitamin C deficiency after the import of citrus fruits like oranges, lemons and limes was blocked in the United Kingdom.

Black currant remains a popular ingredient for juices, jams and jellies in Europe. Recent statistics even show that a whopping 97.8 percent of currants grown worldwide are actually found in Europe.

In the United States, black currants are not as common as they once were, but they have begun to thrive again in areas like Connecticut, Oregon and New York.

Recent efforts have begun to breed improved black currant varieties that are less susceptible to disease, yield more fruit and are more resistant to pests.

Possible Side Effects/Caution

Although uncommon, black currant may cause an allergic reaction in some people, especially in those who have a sensitivity to salicylate, a compound that occurs naturally in some plants. If you experience symptoms like rashes, hives or swelling after eating black currant, you should discontinue use immediately.

Black currant seed oil may also cause side effects for some individuals, including gas, headaches and diarrhea.

Those who are taking phenothiazines, a type of anti-psychotic medication, should not take black currant as it may increase the risk of seizure.

Additionally, black currant may slow blood clotting. If you have a bleeding disorder or are taking a medication for blood clotting, such as Warfarin, you should consult with your doctor before taking black currant. You should also not take black currant prior to surgery as it may increase bleeding risk.
