Citrus bergamia, the bergamot orange (pronounced /ˈbɜːrɡəmɒt/), is a fragrant citrus fruit the size of an orange, with a yellow or green colour similar to a lime, depending on ripeness.
Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of lemon (itself a hybrid between bitter orange and citron[3][4]) and bitter orange.[5] Extracts have been used as an aromatic ingredient in food, tea, snus, perfumes, and cosmetics.[6][7] Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure.[6]
