Blueberry tea offers a number of excellent health benefits, including its potential ability to protect against cancer, strengthen heart health, increase bone density, and boost the immune system. It also helps prevent macular degeneration, improve cognitive function, lower the risk of diabetes, and improve kidney health.

What is Blueberry Tea?

Blueberry tea is made by steeping the dried leaves of the blueberry bush, as these leaves are packed with antioxidants and nutrients, just like the fruit that the bush bears. Blueberries have become one of the most sought-after fruits in recent decades, after the discovery that they had potent antioxidant potential, and can have a hugely positive effect on overall health. These fruit-bearing bushes are native to North America, but were introduced to Europe nearly a century ago, and can now be found in most parts of the world.

The most common species is Vaccinium cyanococcusand the majority of its health benefits are derived from the high concentrations of anthocyanins, polyphenolic compounds and other phytonutrients, as well as vitamin A, C, B and K, potassium, manganese, zinc, and iron.

Benefits of Blueberry Tea

Drinking blueberry tea is a wise choice for anyone experiencing the symptoms of cataracts, low immunity, dementia, Alzheimer’s, diabetes, kidney infections, high cholesterol, hypertension, osteoporosis, low metabolism, nutrient deficiencies, and anemia.

Heart Health

Blueberry tea can provide a boost to your cardiovascular system in a number of ways, beginning with its potassium content, which can act as a vasodilator to reduce blood pressure and lower your risk of atherosclerosis, stroke and heart attack. Secondly, the high concentration of proanthocyanidins, in blueberry tea, have been shown to reduce your risk of heart disease.


The antioxidants found in this powerful fruit tea can significantly affect your cognitive function by preventing oxidative stress and plaque deposition in the brain. This slowing down of your neural connections is what leads to Alzheimer’s, dementia and other neurodegenerative diseases, and the active compounds in blueberries may help protect you from that.


Gallic acid is a naturally occurring antioxidant in blueberries that can reduce inflammation throughout the body, including the stomach. By helping re-balance bacterial levels in the gut, it can optimize digestion, reduce discomfort, cramping and bloating, and ease symptoms of constipation and diarrhea.

Immune System

Our immune system can be bolstered by both the vitamin C and the anthocyanins found in blueberry tea. Vitamin C stimulates the production of white blood cells, and acts as an antioxidant, while the anthocyanins will seek out free radicals and neutralize them before they can cause cells to mutate or undergo apoptosis.


The vitamin A found in blueberry tea means that this herbal beverage can help protect and strengthen your vision. This vitamin is known to act as an antioxidant, specifically in defending against macular degeneration in the retina and slowing down the onset of cataracts.

Kidney Health

Two acids found in this tea, ellagic and hippuric acids, help detoxify the urinary bladder walls by increasing the acidity of the urine. Furthermore, these active components of blueberry tea can reduce the level of oxalates in the body, which can lead to kidney stones.


Blueberry tea is known to lower blood sugar levels by optimizing the function of the pancreas, increasing insulin secretion and improving insulin resistance within the body. For those suffering from diabetes or others at high risk of developing this condition, this delicious tea works as both a preventative measure and a regulatory treatment!

Bone Density

In some studies, consuming blueberry tea has been positively associated with increased bone density and a lower risk of developing osteoporosis. The mineral content in it gives your body a healthy boost, keeping your bones strong as you age.


Iron is present in blueberry tea, as is calcium, which can improve iron uptake by the digestive system. Iron is also a key component of red blood cells, which means more oxygenation to extremities of the body and tissues that require repair or regrowth. Improved circulation can also increase energy levels and prevent symptoms of anemia.

Anticancer Potential

Sarah A Johnson of Colorado University and Dr. Bahram H Arjmandi of Florida University, USA, have co-authored a research paper that highlights the superfood properties of blueberries and their apparent effect on cancer. The anthocyanins found in these berries (and the leaves that make this tea) have anti-cancer potential. By drinking blueberry tea on a regular basis, the gallic acid and other antioxidants in this tea can measurably lower your risk for colon, prostate, breast, lung, and cervical cancer.

How to Make Blueberry Tea?

Making blueberry tea at home is a simple and quick way to give your body a healthy boost, and only requires dried blueberry leaves, hot water and natural sweeteners, such as honey or sugar, if necessary.

Many people make blueberry tea with the berries themselves, but the leaves are also potent sources of nutrients, and even contain trace amounts of caffeine for an extra energetic boost. Dried blueberry leaves can be purchased at most natural health food stores, or they can be collected and dried from the wild. Before collecting and using wild blueberry leaves, be absolutely sure you are harvesting the right leaves, as other berry varieties (that look similar to blueberries) can be hazardous to your health.


  • 2-3 teaspoons of dried blueberry leaves
  • 2 cups of water (filtered)
  • 1 teaspoon of honey or sugar, to taste


  • Step 1: Bring the water to a boil, and then reduce to a simmer (boiling water neutralizes some antioxidants).
  • Step 2: Add the blueberry leaves to the mixture.
  • Step 3: Allow the leaves to steep for 10-15 minutes.
  • Step 4: Strain the tea and add honey or sugar, if desired.

Side Effects of Blueberry Tea

Blueberry tea has very few side effects, and they are limited almost exclusively to gastrointestinal issues and rare allergic reactions.

  • Stomach Issues: The side effects of blueberry tea include stomach upset, indigestion, diarrhea or nausea, but this is only when an excessive amount of this tea is consumed. When consumed in moderation, less than 3 cups per day, these side effects shouldn’t occur.
  • Allergic Reaction: While allergic reactions to blueberries are rare, they can happen, and typically manifest as swollen lips, tongue or gums, as well as skin irritation, redness, swelling, and itchiness. If any of these symptoms develop after drinking this tea, discontinue use immediately.
  • Pregnancy: If you are breastfeeding or pregnant, always speak to your doctor about your particular condition before adding blueberry tea to your diet.
