Thanks Pete. Nice website. Sadly I am zone 6 and could not deal with a big container plant that I would have to shelter in the winter.

Potential Health Benefits of Blueberry Tea
"Although many people drink tea for the taste alone, blueberry tea offers a number of health benefits. Add a cup to your morning meal or pair a glass with dinner to supplement your diet and enjoy several rich health benefits such as:
Improved heart health. High levels of potassium make blueberry tea a heart-healthy beverage. Studies show that enough potassium in your diet can help prevent heart disease. Drinking blueberry tea is an easy way to add potassium to your diet without adding fats, carbohydrates, or sugars found in other potassium-rich foods.
A stronger immune system. That can make you sick less often and speed up your recovery process when you do get sick. Blueberry tea is rich in Vitamin C, which has been shown to help make your immune system work better. Anthocyanins in blueberry tea further strengthen your body's immune system.
Better brain function. Blueberry tea can help your brain work better. This applies also to people with cognitive brain disorders like Alzheimer's or Dementia. For instance, blueberry tea helps prevent plaque from building up in the brain."
Note "If you drink a lot of blueberry tea at once (more than 3 cups), you could feel nauseous or have diarrhea. Make sure to enjoy your blueberry tea in moderation."
