According to Neurotherapy, a body suffers of an ailment because of the chemical imbalance of acid, alkaline, hormones and enzymes in the human system. The treatment developed by Dr. Mehra restores the chemical imbalance of the body. Pressure is applied to different parts of the body mainly with feet and occasionally with hands for a specific duration and a number of times to activate or deactivate the appropriate gland or organ.

According to Neurotherapy, the Immune system fights against many infections, bacteria and viruses. There is no need of medicines to kill the pathogens and suppress the immune system because every individual inherits one lakh genetic codes from the parents for one lakh type of protein markers on the cell surface to respond to antigens to produce antibodies which have evolved over all these years. Thus, there is an inbuilt immunity against the disease.
