Fennel has been a popular remedy for stomach issues. It is referred to as a Stomachic: is a historic term for a medicine that serves to tone the stomach, improving its function and increase appetite.. Fennel oil helps keep the stomach healthy and functioning properly, and maintains the normal function of all the secretions of digestive acids and bile. Furthermore, it protects the stomach from infections and ulcers, thus ensuring the all around health and wellness of the stomach. I feel pretty good so far. :)
Use of fennel essential oil is contraindicated during pregnancy, for breast-feeding mothers, and in cases of epilepsy and estrogen-linked cancers. Please note that this is personal entry of my experience with essential oils and I am not recommending or suggesting anyone to consider ingestion. You need to do your own research and be responsible for your own decisions when using essential oils.
