Maqui Berry (Aristotelia chilensis), is a small dark purple berry native to temperate rainforests in Chile and Argentina. Its fruit has a diameter of about 4-6 millimeters, resembling a blueberry, and is mostly grown in the humid areas of the southern Andes Mountains. Maqui berry is known for its extremely high antioxidant capacity, rich in anthocyanins, polyphenols, and vitamin C. Its ORAC value (antioxidant capacity index) far exceeds that of most common super fruits. Traditionally, it has been used by Mapuche people in South America for anti-inflammatory, healing, and immune enhancement purposes. Modern research suggests that it may help regulate blood sugar, maintain cardiovascular health, and delay skin aging, hence it is made into fruit juice, dietary supplements, and anti-aging skincare products. Although its health benefits are highly praised by the international health food market, some claims still require more scientific verification. Compared with similar berries such as Brazilian berry, maqui berry has a higher concentration of antioxidant components and has become one of the representatives of characteristic functional plants in South America.
