A method for intranasal stem cell therapy provides a non-invasive procedure to inject mesenchymal stem cells directly through the nostrils for stem cell deposition in nerve endings, for the uptake of large number of stem cells directly into the central nervous system, and bypassing the blood-brain barrier. The method involves steps: preparing the patient psychologically and physically prior to receiving the stem cell specimen； intravenously introducing a solution of sodium chloride or Ringer's lactate containing mannitol, and glutathione. The method also includes: clearing and illuminating the inferior turbinate of the nostrils； urging a pair of absorbent fiber soaked with lidocaine and epinephrine into the nostrils； inserting, through one of the nostrils, a 27G 1¼″； needle at a midpoint of the inferior turbinate at a 30° angle relative to the facial plane, and at an angle between 5° to 10° relative to a lateral reference point； and performing post-procedure maintenance.
