Frequently Asked Questions
What is French fennel seed?
French fennel seed comes from Foeniculum vulgare, an aromatic herb in the carrot family native to the Mediterranean. The seeds contain anethole, a bioactive compound responsible for their distinctive licorice-like flavor and most of their medicinal properties, including digestive support, anti-inflammatory effects, and antimicrobial activity.
How much fennel seed should I take and is it safe?
For digestive support, 1-2 teaspoons of crushed seeds steeped as tea 2-3 times daily is a common and safe dose. Fennel is generally well-tolerated at culinary doses. However, concentrated essential oil should be used cautiously and not exceed 0.6 mL/day. People with estrogen-sensitive conditions or allergies to the carrot family should avoid therapeutic doses.
Does fennel seed really help with bloating and digestion?
Yes, fennel has demonstrated carminative (gas-relieving) and antispasmodic effects in both traditional use and clinical studies. Anethole relaxes smooth muscle in the digestive tract, reducing bloating and cramping. Clinical trials have also shown fennel effective for infantile colic and menstrual pain, though more large-scale studies are needed.
