One can obtain many different credentials to practice "holistic" medicine without becoming an RN. I have looked into credentials in naturopathy, homeopathy, irridology, kinesiology, accupunture, herbology, ayurveda, etc. They all cost quite a bit and require that patients pay out of pocket for services. It is not always possible to become licenced in these areas, (allowing you to practice independently and become board certified). The practices which are licenceable (ND and LaC) are only so in a few states. I agree with the other contributors that holism is the recognition of a patient's mental and spiritual status as an essential component in the healing process. Though these factors have been scientifically validated, they are not typically understood well by most instutions of western medicine. Almost any holistic type of credential is based upon the theory that all things are uniquely designed to accept and reject specific frequencies. The main differnce between western medicine and traditional medicine is that traditional medicine is based upon the notion that the frequency causes materilization whereas western medicine believes that matter causes frequency to manifest. Western credentials are more likely to be accecped unilaterally and also to provide you with a lucrative return on your educational investiment. However, if you are already on a level of consiousness where you understand how frequencies affect the healing process. You will not be taught how to identify the imbalances in the individual constitution which lead to traditional therapies through an RN degree. That will require additional training and money. I am sorry for the lenghty responce. I hope that you found this helpful
