In a double-blind study of infants, supplementation of a standard milk-based formula with probiotic organisms (Bifidobacterium lactis and Streptococcus thermophilus) significantly reduced the frequency of colic, compared with the same formula without the probiotics.¹ Another double-blind study found that the probiotic preparation, Lactobacillus reuteri DSM 17938, was an effective treatment for colic in exclusively breast-fed infants.² In another study, L.reuteri DSM 17938 taken once a day was significantly more effective than simethicone, a drug frequently used to treat colic.³ Other double-blind research has confirmed the benefit of probiotics (particularly L.reuteri DSM 17938) in infants with colic.⁴⁵⁶

Carminatives are a class of herbs commonly used for infants with colic. These herbs tend to relax intestinal spasms.

Chamomile is a carminative with long history of use as a calming herb and may be used to ease intestinal cramping in colicky infants. A soothing tea made from chamomile, vervain, licorice, fennel, and lemon balm has been shown to relieve colic more effectively than placebo.⁷ In this study, approximately 1/2 cup (150 ml) of tea was given during each colic episode up to a maximum of three times per day.

In a double-blind study of infants with colic, supplementation with an emulsion of fennel seed oil relieved colic in 65% of cases, compared with 24% of infants receiving a placebo, a statistically significant difference.⁹ The amount used was 1 to 4 teaspoons, up to four times per day, of a water emulsion of 0.1% fennel seed oil.

Caraway relieves intestinal cramping and, in this way, may ease symptoms of colic. One tablespoon (15 grams) of caraway seed is mixed with 8 oz (240 ml) of just-boiled water and steeped in a closed container for at least 10 minutes. Three ounces of vegetable glycerin is added, and the resulting mixture is stored in a bottle in the refrigerator. Up to 1/2 teaspoon (2.5 ml) of the liquid may be given every 30 minutes to a colicky infant or given 15 minutes before feeding.¹⁰

Several gas-relieving herbs used in traditional medicine for colic are approved in Germany for intestinal spasms.¹¹ These include yarrow, garden angelica (Angelica archangelica),peppermint, cinnamon, and fumitory (Fumaria officinalis). These herbs are generally given by healthcare professionals as teas or decoctions to the infant. Peppermint tea should be used with caution in infants and young children, as they may choke in reaction to the strong menthol.

Hyssop has mild sedative properties and may also be helpful in relieving colic, but research is lacking. Though no definitive information on hyssop supplementation is available, 1 teaspoon of hyssop herb steeped in 1 cup of just-boiled water in a closed container for 15 to 20 minutes, then given in sips from a bottle over a period of 2 to 3 hours may help calm colic.
