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.
Used in a base cream or lotion, fennel oil can be helpful for general skin care and especially for dispersing bruises, livening a dull complexion, clearing an oily skin and fighting wrinkles in mature skins.
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.
