Fruits and vegetables are beneficial for your body for many reasons, including the fact that they’re packed with bioflavonoids. What are bioflavonoids? Bioflavonoids are powerful phytochemicals with antiviral, anti-allergy, anti-inflammatory and anti-tumor abilities. Benefits of bioflavonoids include the ability to improve cardiovascular health, heal bruises, fight allergies and more.

What Are Bioflavonoids?

So, what are bioflavonoids exactly? Bioflavonoids are a class of phytochemicals that occur naturally in most fruits, vegetables and herbs. You can also find them in tea, wine and chocolate, as well as some beans and seeds. As a general rule, the more colorful a fruit or vegetable is, the more flavonoids it contains. Benefits of bioflavonoids include the ability to regulate cell signaling, which has powerful effects on the human body.

Benefits of Bioflavonoids

1. Improve Cardiovascular Health

So what are bioflavonoids good for? For starters, they can improve cardiovascular health. Researchers in both Europe and the United States examined the relationship between dietary flavonoid intake and cardiovascular disease. They found that higher intakes of each flavonoid subclass were associated with a lower risk of cardiovascular problems.

2. Reduce Varicose Veins

Benefits of bioflavonoids include the ability to reduce varicose veins. Up to 60% of women, as well as men, suffer from varicose veins. One type of flavonoid in particular, called rutin, works to support the walls of the veins. Studies have shown that rutin can help relieve swelling and pain caused by varicose veins. To get your daily dose of rutin, add citrus fruits, buckwheat and asparagus to your diet.

3. Treat Hemorrhoids

Benefits of bioflavonoids include the ability to naturally treat hemorrhoids. Hemorrhoids can cause severe discomfort and pain. Research has shown that bioflavonoids can help prevent and heal hemorrhoids. Benefits of bioflavonoids include the ability to improve mircocirculation, vascular tone and capillary flow, all of which can help treat hemorrhoids. (1)

4. Treat Hepatitis

Studies have shown that the benefits of bioflavonoids include the ability to treat hepatitis, characterized by an inflamed liver. Catechin, a flavonoid found in matcha green tea, has been shown to help patients suffering from acute viral hepatitis and chronic hepatitis.

5. Heal Bruises

For people who bruise easily, bioflavonoids may be especially beneficial. Benefits of bioflavonoids include the ability to strengthen the capillaries, which can help with healing bruises. Citrus flavonoids can also help increase the effectiveness of Vitamin C in the body, which works to strengthen the immune system. (2)

6. Heal Cold Sores

Studies have shown that bioflavonoids, combined with Vitamin C, can help speed the healing of cold sores. In a study published in Oral Surgery, Oral Medicine, and Oral Pathology, researchers found that patients with herpes infections who received Vitamin C and flavonoids saw a 57% reduction in cold sore symptoms, compared to those taking a placebo.

7. Fight Allergies

Quercetin is a bioflavonoid found in onions, citrus fruits, pineapple and buckwheat. It work as a natural antihistamine and an anti-inflammatory. When it comes to quercetin, benefits of bioflavonoids include the ability to naturally treat symptoms of both food allergies and seasonal allergies. According to research published in the Iran Journal of Allergy, Asthma and Immunology, quercetin can help fight allergy symptoms just as well as some prescription medications, with little to no side effects. Quercetin can help fight allergy symptoms including a cough, runny nose, watery eyes, hives and indigestion. (4)
