I suggest you search an article in Google: "Does Bian Shi really have magical effects?" Liu Ying, deputy director of the Department of Acupuncture and Moxibustion, Dongzhimen Hospital, Beijing University of Chinese Medicine, said: "Bian Shi refers to those needles and pieces of stone that are used for treatment. As long as they have sharp edges and corners, they can stimulate acupoints, not any kind of stone. In recent years, some people have really studied bian stone in pursuit of ancient meaning, such as making it into a therapeutic tool such as scraping board. However, if it is made into a bracelet or necklace, it can't play the role of' purely in shape, because it lacks stimulation to acupuncture points and skin. (2) Dr. Gao, a health care product counter on the third floor of a Tong Ren Tang in Beijing: "It will not obviously improve the human body, nor can it be used to treat diseases. Bian Shi is indeed a tool used by the ancients to treat diseases. Now Bian Shi is only a tool for treating diseases by Chinese medicine. Ordinary people simply wear a so-called stone jewelry, which can't achieve therapeutic effect.

He Liangzhi, director of rehabilitation department of Xiyuan Hospital of Chinese Academy of Traditional Chinese Medicine, said: "Traditional Chinese medicine in China has long been lost, and a large part of the reason for its loss is that it has been replaced by more advanced medical instruments. Bian Shi is just an obsolete tool, which is also a stimulus to acupoints. Acupuncture is more exciting than Bian Shi. In this way, traditional calligraphy gradually lost its value of existence and eventually lost. At present, the new surgical treatment carried out by some Chinese medicine hospitals has not played a very good role. "Therefore, there are so many health centers in Bian Shi.
