Ancient Ayurvedic texts claim that drinking water from a copper vessel cures the three doshas of the body, namely Vata, Pitha and Kapha, by positively charging the water. Eating the food and digesting it releases toxins and creates heat in the body.
You can find copious amounts of copper in foods such as shellfish, nuts, seeds, potatoes, dark chocolate and organ meat.
Copper improves brain and heart health and also has an antibacterial effect.
According to Healthline, copper is an important nutrient and plays a key role in various essential body functions, such as the production of energy and your brain's chemical messaging system.
Filling water in copper cups/vessels for over 48 hours can also kill harmful bacteria in the water.
According to the expert, the most suitable time would be early morning, on an empty stomach for availing all the health benefits.
