Acupunc­ture is a prac­tice that uses very thin nee­dles to stim­u­late cer­tain points on the body, known as acupunc­ture points. These points are locat­ed along merid­i­ans on the sur­face of the body. The nee­dles stim­u­late nerves, con­nec­tive tis­sue and mus­cles. In turn, your body releas­es hor­mones to fight pain nat­u­ral­ly. Some­times, acupunc­ture is used with elec­tri­cal stim­u­la­tion to enhance the effects.
