I bought this product on the suggestion of my friend. Earlier I was using other brand such as colgate and some time closeup . But this is by far best product . It is a herbal based toothpaste by Patanjali Ayurveda which has to chemical involved. Love the freshness it gives to the mouth while using it. It keep me fresh a longer period of time as compered to other product which I was using earlier. The past is dark in colour. it has even reduced by gum problem.
