In early 1970, an odd and interesting phenomenon was noted at a century-old ceramic factory in a rural area in China. This factory had extremely poor working conditions. The workers  stood in mud for much of the work day and the new production manager recognized the health risk of these abject working conditions, becoming concerned that the workers would be troubled with arthritis and other ailments due to standing on the cold, sodden floor for long periods of time.

An ensuing investigation disclosed that the side effects of standing in the mud were the opposite of original concerns. They found that there was not a single case of arthritis among the workers, and that the general health of the workers was excellent.

After interviewing elderly and retired factory employees, the same findings were indicated: no residual effects of any kind were found among the people who had been employed at the factory.

Analysis of a metallic slag in the kiln, accumulated over years of buildup, showed it was made up of 33 minerals. These minerals happen to correspond with 33 essential minerals in the human body, and when heated sufficiently, radiate far-infrared energy exactly like the human body.

Scientists worked feverishly to reproduce the effect in a portable device, resulting in the FIM Energizer.  It has won many awards, e.g., the Gold Medal at the 1986 Zagreb International Fair, the Silver Medal at the 35th Brussels Eureka Worlds Fair for Inventions, and the Chinese Science and Technology Invention Award.
