Fennel seed, an herbal remedy used as a galactagogue, diuretic, expectorant and digestive aid, is generally recognized as safe. Lactation consultant Kelly Bonyata recommends the short-term use of fennel seed tea to treat low breast milk supply in lactating mothers; she also notes its popularity as an ingredient in "gripe water" and other herbal colic formulas for infants. Nevertheless, experts warn against the long-term or high-dose use of fennel seeds. When taken for an extended period, this herbal supplement may cause serious side effects.
Thelarche
According to a 2008 report in the "Journal of Pediatric Surgery," fennel tea is one of the leading causes of thelarche, or premature breast development, in newborns. The authors of the report suggested that caregivers limit the use of fennel seed products in children.
Drug Interactions
The medical information website Drugs.com notes that fennel seed may interact with anti-epileptic drugs, including phenytoin and gabapentin. Fennel seed supplements may increase the risk of seizures in people being treated for epilepsy.
Allergic Reaction
Like most botanical medicines, fennel may cause an allergic reaction in susceptible individuals. An allergy is most likely to occur in people with pre-existing allergies to other members of the fennel family, including carrot and dill. Symptoms of an allergic reaction include rash, hives, wheezing and abdominal cramps.
Decreased Breast Milk Supply
While fennel has been used for centuries to stimulate lactation, large doses may be counterproductive. Fennel contains anethole, a natural compound chemically similar to estrogen. Bonyata notes that phytoestrogens may decrease breast milk supply if used in large quantities.
