The Ayurvedic use of copper vessels dates back many centuries and is a long-standing and proven way of maintaining health.
The fact is that copper is a natural "antibiotic", it is the only metal that can kill harmful bacteria such as Staphylococcus aureus, Salmonella, Campylobacter and many others. In the army, soldiers even have copper tokens, which they put in a glass of questionable quality drinking water in order to avoid intestinal infection.
To maintain optimal water balance, we recommend drinking 2 - 3 bottles of water per day (bottle capacity - 900 ml).
