The tongue scraper has been used in India since ancient times. Using a tongue scraper to clean the tongue first thing every morning is the most effective way to remove the bacteria that collects on top of the tongue each night causing bad breath. Regular tongue scraping not only leads to fresher breath, but also removes these toxins before they can get absorbed into the system. Tongue scraping also has some subtle healing actions that relate to the vital organs and digestive tract. The massaging of the tongue can stimulate these organs while promoting healthy elimination of bacteria and toxins. Ayurvedic literature recommend that tongue scrapers should be made from materials such as copper, silver, gold and brass.
