Fennel Seed for Infantile Colic

A 2003 study found that fennel seed oil significantly improved infantile colic compared to placebo. Fennel seed oil eliminated colic in 65% of infants compared to 23.7% of infants in the placebo group. Fennel seed oil is thought to reduce intestinal spasms and increase motility of the small intestine. Fennel seed may cause digestive or other side effects.
