Safety Considerations

Fennel has a long history of traditional use, however care should always be taken when using herbal plants.

However:

Fennel is generally well tolerated, but concentrated fennel preparations may cause digestive discomfort in some individuals.
Because fennel contains naturally occurring aromatic compounds with mild estrogen-like activity, concentrated use may not suit everyone.
Individuals sensitive to celery, carrot, mugwort, or other related plants should use caution.
Fennel essential oil is much more concentrated than tea or culinary use and requires greater care.
Pregnant or breastfeeding individuals should consult a qualified healthcare professional before using concentrated fennel preparations.
Always consult a qualified healthcare professional before using fennel alongside prescription medications.
