Copper Water Cup: Benefits & Safety – Is it Safe?

For centuries, Ayurveda, a traditional Indian system of medicine, has advocated for the use of copper in various health practices. Copper, a naturally occurring element, possesses inherent antimicrobial properties. Toxicity from excessive copper intake, however, represents a potential health risk. The copper water cup, employed as a vessel for drinking water, therefore presents a confluence of potential benefits and hazards that warrant careful examination.
