It is very improbable that any doctor will ever use IPT for all the diseases listed in this section. Most doctors will choose their own specialties, although a few may choose to be general IPT practitioners. The apparent wide applicability of IPT has been a blessing for many patients. But, ironically, it has also been a hurdle for IPT's credibility to overcome. IPT is reported to work for just too many things.
Many people are very wary and skeptical of apparent panaceas.
The general feeling is that panaceas do not and could not exist. These things could be considered panaceas, although they usually are not called such. It could be that IPT synergistically taps into a number of fundamental mechanisms of the human body, including metabolism, blood chemistry, immune function, detoxification, and membrane transport. If this is so, then it would not be so hard to accept that IPT, like good diet and rest, helps in the treatment of such a wide variety of diseases. Perez Garcia do not claim that IPT is a panacea.
