Gripe water has been used for more than 150 years as a treatment for teething, colic and digestive complaints in babies. No large-scale studies have evaluated the safety or efficacy of gripe water, so it is generally regarded as a form of folk medicine. While gripe water might have some benefits, it might not be worth the potential risks for all babies. Concerned parents should consult a qualified health care provider before administering gripe water to special-needs or preterm babies, or children with a history of allergies.
Pain Relief
According to a 2000 report published in the Journal of the Royal Society of Medicine, gripe water appears to effectively relieve pain in infants. The journal attributes most of this effect to gripe water's sweet flavor, which can ease pain and temporarily distract the baby.
Gas Reduction
Dill weed and fennel, two closely related herbs, might help to reduce gastrointestinal upsets and the symptoms of gas in babies. This use is supported by centuries of folk use, but no studies have evaluated their efficacy. Some gripe water formulas also contain ginger, which is reputed to ease gas and reflux.
Hormonal Effects
Fennel in gripe water might influence a baby's developing endocrine system. Fennel contains anethole, a natural compound structurally similar to estrogen. In November 2008, the "Journal of Pediatric Surgery" advised parents to limit a baby's intake of fennel products. Large doses have been linked to premature thelarche (breast development) in newborns.
Sedative Reactions
Many gripe water formulas contain low doses of chamomile, an herb known for its weakly sedative properties. Chamomile might help to ease pain and restlessness, but the National Institutes of Health warn that it can cause drowsiness.
Allergic Reactions
Almost all herbs and medicines can cause allergic reactions. Herbs such as ginger, fennel, dill and chamomile have been linked to allergic reactions in babies. Symptoms of an allergic reaction can include rash, hives, diarrhea, wheezing and throat swelling.
