Anise tea has long been a homeopathic remedy for infants struggling with symptoms of digestive gas. For the majority of newborns the first three months of life involve gas pains. Their digestive tracks simply take time to acclimate to life outside the womb. In many cultures tea made by adding boiling water to crushed Anise seeds, and letting it steep, brings relief.
There are many suggestions on line for how to manage this. There are also differing opinions on the topic. Using anise tea once a day for a few days should not be a problem. This is not something you would continually use over time. You could occasionally add it to baby’s bottle to avoid possible gas pains. I would only use it to relieve gas symptoms as they are occurring. The ratio I am aware of is 1/2 teaspoon crushed anise seeds to 2 cups boiling water. Prepare the tea, store it in the refrigerator. Add 2 teaspoons tea to two ounces of formula or breastmilk.
Please read the following articles to answer your questions. This information was passed on to me from a new mom whose mother used this remedy for her and her siblings. Grandma said to use this once a day, sparingly. Do not overmedicate your baby!! JUDY
