This helpful, unassuming tool is the low-hanging fruit of an Ayurvedic routine. 5-7 gentle scrapes on your tongue first thing in the AM will help remove toxins that have accumulated during the night, freshen your breath, remove the stubborn coating on your tongue (it won't come off all at once but you'll see a difference after a week) and stimulate proper digestion. Stainless steel. Wash with soap and water between uses.
