The tongue scraper is recommended to be used first thing in the morning. Take the curved edge as far back as comfortable on the tongue and scrape forward. Work the middle and each side of the tongue, using approximately 7 strokes. If you find this induces the gag reflex, try being more gentle and starting further forward on the tongue.
The tongue scraper helps remove coating on the tongue which contributes to bad breath and accumulation of bacteria. According to Ayurveda the coating of the tongue is a build up of excess toxins.
