The lingonberry is an evergreen creeping shrub which produces edible, red berries which ripen in August. Also known as the mountain cranberry, it grows in North America and Eurasia.
Lingonberries have numerous health benefits. They are a good source of vitamin A, vitamin C and magnesium. Studies have shown they contain large amounts of antioxidants, which can reduce inflammation and increase red blood cell count and liver enzymes. Native Americans have used lingonberries to help those suffering from both cardiovascular disease and diabetes. Even though they are not well known in the United States, lingonberries are sometimes available in health food stores or online in juice form, powder form, frozen or even in jams.
