The Ayurvedic Practice of Tongue Scraping: Benefits Backed by Science
By Lakshmi Harilela for AyurvedaHK
In the ancient science of Ayurveda, daily self-care rituals, or Dinacharya, play a crucial role in maintaining overall health. One such practice, Jihwa Prakshalana (tongue scraping), has been revered for centuries for its profound benefits on oral hygiene, digestion, and systemic detoxification. Modern research now validates many of these claims, making tongue scraping a simple yet powerful addition to your wellness routine.
Why Scrape Your Tongue? The Ayurvedic Perspective
According to Ayurveda, the tongue is a mirror of internal health, reflecting the state of digestion (Agni) and the accumulation of toxins (Ama). Overnight, the body eliminates metabolic waste, some of which deposits as a coating on the tongue. If not removed, these toxins can be reabsorbed, leading to imbalances such as bad breath, poor digestion, and weakened immunity 610.
Tongue scraping is traditionally performed using a U-shaped copper or stainless steel scraper, materials chosen for their antimicrobial properties. Copper, in particular, has been shown to inhibit harmful bacteria while supporting beneficial oral flora 410.
Scientific Benefits of Tongue Scraping
1. Improves Digestive Health
A 2018 randomized controlled trial published in Complementary Therapies in Medicine found that participants who practiced daily tongue scraping reported significant improvements in digestive symptoms, including reduced constipation (odds ratio: 2.80) and better stool quality. The study attributed this to the removal of toxins that interfere with taste perception and enzymatic signaling for digestion 25.
2. Enhances Oral Hygiene and Reduces Bad Breath
Research indicates that 85–90% of halitosis cases originate from bacterial buildup on the tongue. A systematic review found that tongue scraping is more effective than brushing alone in reducing volatile sulfur compounds (VSCs), the primary cause of bad breath 410. Another study noted a significant reduction in anaerobic bacteria linked to plaque and gum disease 9.
3. Boosts Immunity
The mouth is a gateway for pathogens, and an unclean tongue can harbor harmful bacteria. By removing this biofilm, tongue scraping supports the immune system’s first line of defense. Copper scrapers, in particular, have been shown to reduce bacterial load significantly 48.
4. Sharpens Taste Perception
A clean tongue allows taste buds to function optimally. A study highlighted that participants who scraped their tongues twice daily experienced improved taste sensitivity, which Ayurveda links to better digestion by triggering proper enzyme secretion 11.
5. Promotes Overall Well-Being
Ayurveda teaches that different sections of the tongue correspond to internal organs. Gentle scraping stimulates reflex points connected to the lungs, liver, and intestines, promoting detoxification and organ function 610.
How to Scrape Your Tongue Correctly
Timing: Perform this ritual upon waking, before eating or drinking.
Tool: Use a copper or stainless steel scraper (avoid plastic).
Technique:
Extend your tongue and place the scraper as far back as comfortable.
Gently pull forward 5–10 times, rinsing the scraper between strokes.
Follow with oil pulling or brushing for complete oral care 68.
Conclusion
Tongue scraping is a time-tested Ayurvedic practice with modern scientific validation. From enhancing digestion to boosting immunity, this simple habit offers profound benefits. As research continues to explore its mechanisms, one thing is clear: a clean tongue is a foundation for holistic health.
