Gripe water is an over-the-counter liquid supplement of sodium bicarbonate and herbs, such as fennel, ginger, chamomile, dill, lemon balm, or peppermint, depending on the formula. It is marketed as a remedy for teething pain, hiccups, colic, and other common baby issues. The original gripe water contained alcohol, which is toxic to babies, but todays formulas are alcohol-free. Gripe water is thought to help soothe tummy troubles, but experts don't fully understand how it works. The herbs in gripe water, such as dill, fennel, and ginger, can help with gas relief and stomach discomfort by relieving gas buildup. Gripe water is considered an herbal remedy, and the FDA has not approved it. While many parents swear by it, there is no proof that it works to ease stomach discomfort in babies who may suffer from colic.
