40 neodymium magnets which develop a power of 2400 Gauss each to promote healing and reduce swelling. Recommended for limited therapeutic sessions lasting no more than 4 hours! The magnets are distributed in correspondence to the flexor and extensor tendons, fetlock, and bulbs of the hoof. Boots are made of breathable micro-porous material to reduce heat. Made in Italy. Magnetic Therapy is a non-invasive drug free treatment of injuries. The magnetic fields stimulate blood flow and at the same time also help with cellular growth and ligament repair. Because of their polarity, magnets draw blood to the area that they are placed in. Please consult your veterinarian before beginning any magnetic therapy treatment.
