The formulation now varies according to brand and the country of manufacture. In most countries alcohol is no longer in the product. Sugar may or may not be in the product. Sodium bicarbonate, dill seed oil, fennel oil and sometimes ginger extract are the ingredients claimed to be effective. Evidence of<unk> 's effectiveness has been limited to anecdotal accounts. Its commercial success has led to imitation brands of varying formulas.<unk>  is recommended by some pediatricians and alternative practitioners as a 'natural' option. It is available in the United States as an over-the-counter dietary supplement. A 2000 review in the Journal of the Royal Society of Medicine found that most of the ingredients in Woodward's<unk>  are of little value in relieving infantile discomfort and that any benefit may be no more complicated than the baby receiving some sweet-tasting liquid. A 2012 review also came out against the use of these products. Yet, commercial attention has continued to grow as companies have produced product options claiming to provide various digestive benefits, like Wellements who introduced a probiotic<unk>  in 2016. In a 2015 study of 350 infants conducted in Puducherry, India, two-thirds of mothers of infants ages 1 to 6 months admitted to administering<unk>  to their children at least once a day. The mothers believed that<unk>  helps in digestion and prevents stomach ache. However, infant colic, vomiting and constipation were significantly more common in<unk>  administered infants compared to those who were exclusively breast fed. The study did not indicate the rate of constipation or vomiting prior to the use of<unk>  to compare with during use. Constipation was reported for 19.5% of the infants who were given<unk>  compared to 5.8% for those who were not. In Canada,<unk>  comes in both original formulation and alcohol-free versions. Since there is a ban in the United States, the original formulation is usually not able to be shipped outside of Canada.
