To maintain and promote health by vulcanization molding of the raw material prepared by incorporating a specific amount of metallic powder, such as titanium oxide, which is mainly composed of succinite and has an effect of stimulating the human body by radiating slight radiations into rubber to a ring for fingers, etc., and wearing the molding.

The powder mixture which is mainly composed of the succinite powder containing succinic acid activating all the enzymes of organisms and is compounded with plural kinds of metals, such as titanium oxide, radiating radioactive materials is incorporated at 50 to 150% by weight into the raw material for forming rubber and the mixture is subjected to vulcanization molding, by which the annular ring 1 or arm ring 2 is manufactured. The succinite to be compounded with the rubber raw material is the product resulted from the fossilization of the resins of pine and oak tree plants in the ground and is an amorphous organic compound containing the resin acid, such as succinic acid. The succinic acid regulates the physiological functions of the organisms. The titanium oxide radiates far IR rays to the skin and has an effect of relieving the pain of the muscles and accelerating blood circulation. Silver oxide, tungsten oxide, etc., are usable as the metallic powder.
