Blueberries are a plant known above all for their fruit and their antioxidant properties. However, its benefits also extend to other parts of the plants, namely the leaves. Bilberry leaf has a long history of use in traditional practices, and more recent studies are beginning to reveal its therapeutic value.
Rich in Antioxidants
Like the fruits, blueberry leaves contain a high concentration of antioxidants, including flavonoids and phenolic compounds. These compounds are essential for neutralizing free radicals in the body, helping to prevent premature aging and combat oxidative stress, which is associated with several chronic diseases, such as cancer and heart problems.
Controlling blood sugar levels
Scientific studies have highlighted the effectiveness of blueberry leaf in regulating blood sugar levels. According to research published in the Journal of Nutrition, blueberry leaf extract can improve insulin sensitivity and help maintain glucose levels longer. This could be particularly beneficial for people with type 2 diabetes or at risk of developing the disease.
Cardiovascular System
Blueberry leaves are rich in anthocyanins, which contribute to helping reduce inflammation and LDL cholesterol ("bad" cholesterol). A 2017 study showed that these components can help improve the function of the cells that make up the walls of blood vessels, helping to regulate blood pressure and prevent heart disease.
Digestive System
Blueberry leaf has anti-inflammatory properties that can promote digestive health. Its infusions are traditionally used to alleviate symptoms of gastrointestinal problems, such as diarrhea, thanks to the tannins present, which have an astringent effect.
Antimicrobial Properties
Studies indicate that blueberry leaf extract has antimicrobial effects and may help inhibit the growth of certain pathogenic bacteria, such as Escherichia coli, associated with urinary tract infections, and Helicobacter pylori, known to cause gastric ulcers.
Eye Health Support
Consumption of antioxidants present in blueberry leaves, such as flavonoids, has been associated with improved eye health. They help protect against macular degeneration and other age-related vision problems by reducing oxidative damage to eye tissue.
How to Consume Blueberry Leaf?
Blueberry leaf can be consumed in the form of an infusion and can be enjoyed hot or cold, and combined with other plants. Our suggestion is to try our combination with Hibiscus, Blueberries and rose petals.
Including blueberry leaf in our daily routine can provide a series of benefits to our health, from blood sugar regulation to cardiovascular and digestive protection. Additionally, as it is a rich source of antioxidants, this leaf is an excellent option for those looking for a natural approach to supporting overall well-being.
