What is Allium nigrum or black garlic?

Allium nigrum, commonly referred to as black garlic, broad-leaved leek or ornamental onion, is a Middle Eastern species of wild onion with no aroma typically associated with its relatives. Native to Turkey, Cyprus, Syria, Lebanon and Israel, it’s also a popular choice for decorative planting in many other regions.

Despite its name, Allium nigrum displays creamy-white or pale lilac flat clusters of starry silvery florets with a green center. Blooming in late spring to early summer, this hardy bulb adds beauty to the perennial garden and functions well as a cut flower. The clusters are roughly 8-10 cm in diameter.

Allium nigrum contains an exceptional blend of nutrients – it’s often referred to as a “Natural Antibiotic.” Boasting more than 200 chemical compounds, it has impressive health benefits. This can be attributed to its range of vitamins, minerals, and antioxidants. Vitamin C, B-complex vitamins (B1, B2, B3, B6, B9), and vitamin D are among the vitamins found in Allium nigrum. Iron, zinc, folate, calcium, silicon, sodium, potassium, selenium, manganese and magnesium are some of the minerals present. Furthermore, its antioxidant content is at least double that of fresh garlic.

Uses of Allium nigrum or black garlic: Increased antioxidants compared to raw garlic and support for respiratory, weight control, blood sugar management, liver, cholesterol health and heart. Additionally, some cancer fighting properties have been noted as well as an anti-inflammatory effect and neural protection. Finally, it bolsters the immune system and displays antimicrobial characteristics that may even benefit brain function and memory.
