A tongue scraper is a long, thin, flat piece of metal ( or plastic ) shaped like a” U” to remove bacteria, food debris, and dead cells from the surface of the tongue. ” You ostensibly reach back as far as you can on the lips, stick your tongue out, and carry this forward a few times along your tongue”, Burhenne explains. It’s a tradition practiced for centuries in Ayurveda, known as Jihwa Prakshalana.
