How it is classified

Herbal actions
Carminative, Antispasmodic, Galactagogue. Energy: warming.

How people take it

Food, tea and essential oil.

Where to get it

Grown in Europe, India, Egypt and China. Buy whole seeds in spice shops and bulbs in produce sections. Choose oils only from makers who list dose and safety information.

Be careful

Food amounts are safe. Fennel essential oil is strong and can cause seizures in small children. Anethole, a compound in fennel, may act like estrogen, so avoid medicine amounts if you are pregnant or have hormone-sensitive cancer.

Avoid if: pregnancy; hormone-sensitive cancer; epilepsy; children under 12.

The honest take
