Metals are traditionally used in Ayurveda which help to restore and re-balance the Doshas (Vata, Pitta, and Kapha) for the better function of the body system and to help the body naturally detox, preventing many ailments and diseases. Kansa Vatki is a special metal foot massager made with a blend of copper, Zinc, and tin which has been used for centuries as a part of Ayurveda massage treatment that stimulates the vital nerves and pressure points and helps to relax and rejuvenate tired feet. This foot massage tool is best for those who spend long hours standing on their feet.
