Horses are electrically charged. So are people. Sound a bit bizarre? Because of this electrical presence, the use of magnets has been a part of the therapeutical approach to treatment of injuries and other maladies since the 18th century.
All of the cells in a horse–the same is true for humans–have a natural, resting electric current flowing through them. This is known as resting electrical potential, and it is regulated and maintained by the membrane of each cell. This electrical potential is not something that just happens to be present for no good reason. It is necessary for normal cell function and metabolism. Without it, a cell ceases to function and is dead.
Blood is an electrical conductor, and electrolytes are compounds that can carry electric current within the body via the movement of ions such as sodium, potassium, calcium, and magnesium. When these ions with their positive and negative charges pass by a magnetic field, a separation of ions occurs. More later about what the separation of ions means in the way of healing.
The electrical potential of a cell is measured in millivolts (MV). Normal for most resting cells is 90 millivolts of potential. When a cell suffers traumatic injury, the potential might increase to about 120 MV. On the other hand, a cell with a long-standing injury might have only a potential of 30 MV.
This is where magnetic therapy comes in.
Magnetic therapy is said to have a positive effect on the ion exchange and regulation, thus working to get the cell back to its potential with a normal number of millivolts.
Magnetic therapy is not new. It has been around for about 2,000 years. Some scholars believe that the term “magnet” was derived from Magnes, a Turkish shepherd who discovered iron deposits that were attracted to the nails in his sandals. These deposits, now called magnetite (a form of iron), were known to the ancients as lodestones.
