Ramzan is coming and you will find miswak being sold everywhere. Moreover, its use too will increase during the month of fast. From place to place one can find people selling miswak as it is regarded as a practice which Muhammad (PBUH) adopted.
A traditional and natural alternative to the modern toothbrush, it has a long, well-documented history and is reputed for its medicinal benefits. A Google search on miswak and its importance in Islam throws several findings.
A few of them are here:
