Bergamot Essential Oil (Citrus bergamia) The aroma is reminiscent to that of orange, but it is wonderfully more complex. It almost seems to possess an underlying floral characteristic to it. Drinkers of Earl Gray tea are especially familiar with the flavour and aroma of bergamot as the oil is used to flavour the tea. Bergamot Essential Oil may be helpful in use during periods of depression, sadness or grief, and it is known for its ability to help combat oily skin and acne.
