A double-blind, placebo-controlled clinical trial in colicky infants found that a supplement containing chamomile, melissa, and fennel significantly reduce infant crying time after one week.5
A study in rats reported that fennel essential oil was effective in protecting against chemically induced liver damage.6

Non-toxic, non-irritant and non-sensitising. Always test a small amount first for sensitivity or allergic reaction.

Fennel essential oil is a narcotic when ingested in larger doses and therefore it is recommended to use in very low concentrations. For internal use, we recommend consulting a physician.

DO NOT USE if you are pregnant or epileptic.

Fennel essential oil may stimulate estrogen production and increase lactation, as well as act as a stimulant to the lymphatic, circulatory and digestive systems. It may also act to break up and flush out toxins, cleansing the tissues. Therefore, it is CONTRAINDICATED FOR ESTROGEN-MEDIATED CANCERS.

Note that there is a Bitter fennel oil which causes sensitization and should not be used on the skin at all.
