Kansa - the Hindi/Sankrit term for bronze - is derived primarily from copper, a metal very celebrated in Ayurveda for detox, and kapha-alleviating properties. Metals are traditionally used in Ayurveda as healers to negate toxicity within organs. Copper is revered in Ayurvedic medicine for helping restore better lymphatic function and drainage (a better working lymphatic system can help the body naturally detox, preventing many ailments and disease) - and you see it used in a wide variety of ways: as a vessel for water storage to enhance the healing abilities of drinking water, to wands for better circulation. The history of the metal dates back to the origins of Ayurveda itself - 5000 years or longer.
