The Bergamot tree was originally from Asia, but now grows prolifically in Itally where a small town is believed to be the inspiration of its name. The town of Bergamo. The essential oil is obtained by expressing the peel of the fruit (like a miniature orange) of the tree.
Bergamot acts as an anti-depressant. It has powerful cleansing properties which also help to generate movement in the subtle energy system. This movement of stuck energy helps to lighten ones mood and brings with it a feeling of hope. It is known as the oil of self-acceptance and can be used in a room spray or in a 2% mix with a carrier oil to make an uplifting massage oil (2% or less prevents it from having a photosensitising affect on ones skin. Higher percentages can cause the skin to burn in the presence of sunlight). Bergamot lifts the spirits while relaxing the the mind.
In treating cystitis, Bergamot essential oil is most useful at the beginning of the infection. It helps prevent the infection from spreading upwards, and is usually added to ones bath water. As a wash it can also be used to treat mild vaginal itching and discharges (although the source of discharges should be investigated).
Bergamot has excellent antiseptic properties which make it ideal for treating acne, infected skin conditions and oily skin. It can be used in a face massage oil, or added to creams and washes. (Again the 2% rule would apply)
There are many other uses for Bergamot essential oil, but these three are what it is most well known for and where it is most efficient as a healing essential oil.
