DO THESE WORK OR SHOULD I JUST BUY A INFARED LAMP??? FOR FRIBROMYALGIA AND ARTHRITIS???? The Only UL Approved TDP in the world What is a TDP Lamp? Early in 1970, The Chinese government decided to send an investigation team headed up by Dr. Gou Wenbin, to a century-old ceramic factory located in a rural area of central China. The team's goal was to investigate phenomenon that was reported by the production leader of the factory. The production leader recognized that there were no single complaints related to arthritis and other working related pains despite the intense physical working environment. After interviewing many elderly employers, the investigation team confirmed the production leader's observation: there were no complaints related to pain and arthritis among the factory workers. The conclusion of the research suggested that the clay was the reason for such few pain symptoms. After an intense study by research institutes, hospitals, and schools, the TDP Lamp was invented to mimic the properties of the clay. The key part of this lamp is its heat-treated black clay, which contains 33 different essential mineral elements for the human body. This ceramic plate emits a unique spectrum-electromagnetic waves in the infrared range of 2 to 25 microns-which is compatible with the BIO-spectrum waves released by the human body. This allows for maximum absorption. The absorbed energy promotes microcirculation, metabolism and strengthens immune system as well as tranquilized pain on the body In China, the TDP Lamp is called 'Miracle Lamp'
