Inflammation from the organization of spinal cord, nerve radix, acetabulum and muscle.
2) To increase the intervertebral and vertebra hole clearance, alleviate or even release the stimulation and pressure that on the never radix.
3) To dispel muscle spasm, restore the balance of the neck spine; Reduce the inner pressure of intervertebral disk, buffer irradiation pressure from the intervertebral disk.
4) To tow out the clearance of the little joints, eliminate the pressure of the vertebral film, reconvert the nature rank and mutuality between the cervical vertebras.
5) To stretch the crooked vertebra artery which in the cervical vertebra, improve the arterial blood supplying.
6) To stench the cervical vertebra pipe crabwise; Extend the spinal cord, to flatten the wrinkles of the yellow ligament, increase the volume of the vertebra pipe relatively.
