The ultrasonic pulse frequency of buffalo horn plate is 20-2000 kHz, while that of buffalo horn plate is only 200KHZ, which has no biophysical characteristics such as trace elements and far infrared rays. In different clinical uses, the scraping effect of buffalo horn tends to be cold, and its main function is to dredge meridians and qi and blood. Bian Shi is warm in nature, and its function is mainly to help Yang Qi, warm meridians and dredge veins. Bian Shi's therapy not only relies on the mechanical force of massage, but more importantly, it relies on its warming meridians to supplement the "power" needed for the operation of qi and blood, and further promotes the operation of qi and blood along the meridians. Bian Shi has a good clinical effect on cold syndrome, especially deficiency cold and cold coagulation and blood stasis caused by yang deficiency. Enhance and clear functions are different. The direct function of buffalo horn scraping is "purging", which leads the pathogenic factors or qi and blood stasis in the body out of the body from acupoints or some parts, thus achieving the purpose of eliminating pathogenic factors and strengthening the body resistance. The "catharsis" effect of lithotomy therapy is much smaller. After a period of manipulation, local reddish skin will appear, but there will be no purple scraping spots, and patients will feel comfortable and warm.
