Fennel Essential Oil

Fennel oil is a remedy for digestive complaints such as flatulence, constipation, colic, nausea, vomiting, anorexia, dyspepsia and hiccups. It is also used in cases of obesity, as it promotes that 'full feeling' and has a diuretic effect that helps to disperse cellulite. For the mind, it adds courage and strength in the face of adversity. 
Origin of Fennel Oil
The name is from the Latin word 'foenum' which means 'hay'. It grows up to 2 meters (6 feet) in height and is a biennial or perennial herb, with green feathery leaves and golden yellow flowers, that bees like. 
In Medieval times it was known as 'Fenkle' and was a very popular herb with the ancient Chinese, Egyptians and Romans, who believed it conveyed longevity, courage and strength, as well as warding of spirits. Not only did they use it to strengthen eyesight, but they also used it for snakebites, colic and to rid dogs of fleas.
Uses

For the mind, it adds courage and strength in the face of adversity. It has a cleansing and toning effect on the skin, helping with bruises, sorting out overly oily skin and to fight wrinkles in more mature complexions (possibly due to the estrogenic properties of the oil).
It has a toning effect on the spleen and liver, that helps with the results of excess drink and food. It is also used for increasing insufficient milk in nursing mothers - but for boosting breast milk, rather use the fresh herb, since the oil contains very high concentrations of trans-anethole.
