Bilberry is found in areas that are acidic in nature, and their soils contain inferior nutrients. They can be seen in temperate regions and subarctic regions of the world.

They noticed that all things are going well in favor of human health, and their cardiac health is improving day by day.

Another study of 12 weeks with the people taking 320 mg of anthocyanin daily basis suffered a rise of 12% HDL cholesterol in their body that is good for health. Not only this, but they also reported that their LDL drop 14% during this duration.

Gingivitis is the inflammation of gums. To find out the reality, Researchers researched three groups of people suffering from gingivitis. They gave 500mg of bilberry extract to the first group, 250mg to the second group, and the third group left for medication only.

They noticed that people of the group who consumed 500mg of bilberry extract recovered a lot as compared to the other two groups. To support this theory, they passed a statement that anthocyanin is responsible for this activity. It acts as a marker at the site of inflammation due to which recovering agent with phagocytes immediately reaches the place of infection leading to a quick recovery.
