Dr. Duke's Phytochemical and Ethnobotanical Databases

Blueberries have been considered beneficial for centuries in Native American, First Nations and other cultures around the world -- anywhere they are grown.  
Check out the following USDA Agricultural Research Service (ARS) searchable database titled: "Dr. Duke's Phytochemical and Ethnobotanical Database."  Dr. Duke was a pioneer researcher at North Carolina State University and was taking "Nutraceuticals" long before there was a term for it.    Note this database includes all plant parts including leaves, blossoms, roots as well as fruit.
