Tamra Jal, or water stored overnight in a copper bottle, is a centuries‑old Ayurvedic practice returning to popularity—celebrated for its antimicrobial effects, antioxidant potency, and wellness benefits. When water sits in pure copper for 6–8 hours, trace copper ions infuse the liquid , helping eliminate waterborne bacteria and balancing the doshas: Vata, Pitta, and Kapha.

Potential Benefits : 

1. Aids digestion by stimulating peristalsis and soothing the gastric lining.
2. Supports immunity and skin health thanks to anti-inflammatory and antioxidant effects.
3. May improve heart function and metabolic balance, with hints of weight and thyroid support.

Safety Precautions : 

1. Limit intake to once or twice a day—excess copper poses toxicity risks including nausea, abdominal pain, diarrhea, liver and kidney damage. Vulnerable groups include people with Wilson’s disease, infants, and pregnant women.
2. Use only plain, filtered water—never acidic liquids like lemon water, juice, tea, or coffee, which can react with copper and elevate toxicity risk.
3. Clean bottles every 2–3 days using natural cleaners (lemon + salt or vinegar + salt); avoid abrasive detergents that damage the surface.

How to Use Safely : 

1. Choose certified pure copper bottles with no harmful alloys.
2. Store daily fresh and give bottles breaks to prevent copper overload.
