What is the effectiveness difference between the amethyst and jade bio mats?
At first Jade was the obvious choice for the Koreans, it has been used for thousands of years as a healing stone.Then they decided to do actual tests and studies with hundreds of different stones, crystals, glasses, plastics…to see if any made significant differences in the human bio-compatibility of the infrared. They discovered that Amethyst made a huge difference and the body used the light 200% more effectively and combined with 10hz infrared, the healing response and testimonials from remissions was unheard of. So they did test batches, some with and some without, the Amethyst ones had huge numbers of remissions and responses, and the non-amethyst ones had some cases, but not nearly as frequent.
