Bianstone is a type of stone with therapeutic effect, which is recorded in the literature of every dynasty. However, as time goes on, Bianstone has passed into oblivion. Owing to its rarity and the lack of methods in obtaining it, Bianstone Therapeutics has disappeared from history books as early as the Eastern Han Dynasty.
The Sibin pumice was discovered by a famous musician in China by the name of Professor Yang as a result of finding and replacing for the 2 damaged stone muscials out of 13 stone musicals unearthed in Shandong. After much hard work, Mr Yang managed to find the stone used to make the unearthed stone musicals used in Imperial court music and ritual and revive the lost music. Mr Yang's discovery of the Si Bin Stone led to a re-discovery of the ancient traditional Chinese musical instruments - the scared Chimes Bell. News of this discovery hit the media in Asia as well as Europe.
In the early 1980s, thanks to scientific research and petrophysical test of different types of stones found in China by Professor Geng from Beijing, a type of stone called Sibin pumice discovered by Mr Yang dating from the ancient times was found to be the most suitable for making Bianstone tools. Professor Geng from Beijing conducted several tests on this mysterious Si Bin Stone and concluded very strongly that the stone has the quality for the long-lost Bian Stone Healing. Also, the sibin pumice stone site also tally with the historical record of bian stones found in historical record books. But this Sibin pumice stone is still considered very rare as it can only be found in Sibin Area in China. As a result, a green therapy that has been lost for thousands of years reemerged as early as 1990. After years of development and clinical application, it was found that Bianstone has a remarkable and toxicity-free therapeutic effect. And a series of Bianstone tools and accessories has been developed consequently. These Bianstone products not only undergo rigorous tests but also obtain the security certifications of EU and China.
