Thousand years ago, we used to have aniseeds after any meal.Due to this magical aniseeds lacks of lactobacillus used to enter the abdomen.
This ‘pratha’ tradition was due to this that after every meal aniseeds were eaten, this was the scientific reason.
Do not/ avoid sugar coated, fancy ones and roasted ones do not work here.
Fact : the first culture for curds was made from aniseeds.
