China is the first country in the world to discover and apply magnetic fields to cure diseases. Magnetic field treatment can be traced back to more than 2000 years ago. According to the Historical Records，in the early Western Han Dynasty， people had used magnets to cure the disease, but because of the limitation of historical conditions, it was limited to magnetic field treatment. Hence, the development went slow. In the past ten years, magnetotherapy has developed rapidly in China, and has achieved good accomplishments in clinical application, experimental research and mechanism exploration.
It is reported that permanent magnetic NdFeB magnetic steel N40, D12X2mm can be used for human's acupoint therapy. Its magnetic induction intensity is about 1800-2000 Gauss which ranks mediem in the field of magnetic therapy. The application method is very simple, just to directly attach it to the skin of acupoint.
The main effects of magnetic therapy are as follows:
1 Easing pain
2 Reducing inflammation swelling and detumescence
3 lowering blood pressure and lipid
4 Surpressing tumor in some degree
Warning: Do it under the doctor's guidance.
