I used to live in Germany, and there was a product called "Kinder Tea". It was for upset stomachs in infants. It came in a blue can. It was a dry brown mix and you put some in a bottle of cold water.
It worked great. It was kind of licorice like stuff.
OH I remember Kinder Tea!!! I lived in Germany for a year when my oldest was a baby and he loved the stuff and it seemed to be Great at soothing a cranky little one I have tried to find it here at International Grocery stores but no such luck.
