Some people brush gently with a paste of activated charcoal and a tiny bit of lemon juice to remove surface stains.
Caution: Lemon’s acidity can erode enamel, and charcoal is abrasive. Overuse can damage teeth permanently.
Digestive or Detox Drink (Oral Use)
Activated charcoal is sometimes taken in water for temporary relief from bloating or gas.
Caution: Lemon may make the water acidic, and charcoal can interfere with nutrient and medication absorption. Never use daily without medical advice.
Risks & Safety
Dental damage: Acid + abrasive charcoal = enamel erosion.
Medication interference: Activated charcoal can bind medications and reduce effectiveness.
Digestive upset: Can cause constipation or nausea if taken in excess.
Bottom Line
While the lemon-charcoal combo is widely shared online as a cheap “market-free” remedy, it carries real risks. It is not a safe long-term substitute for proper nutrition, dental care, or medical treatments.
