Citrus bergamia, the bergamot orange (pronounced /ˈbɜːrɡəˌmɒt/), is a fragrant fruit the size of an orange, with a yellow color similar to a lemon. Genetic research into the ancestral origins of extant citrus cultivars found bergamot orange to be a probable hybrid of Citrus limetta and Citrus aurantium. Extracts have been used to scent food, perfumes, and cosmetics. Use on the skin can increase photosensitivity, resulting in greater damage from sun exposure; excessive consumption can be toxic.
