Bergamotto

Citrus bergamia, the bergamot orange , 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 and bitter orange. Extracts have been used as an aromatic ingredient in food, tea, snus, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure.
