A Board Certified Holistic Nurse is a registered nurse (RN) who has obtained certification in holistic nursing through a recognized certifying body, such as the American Holistic Nurses Credentialing Corporation (AHNCC). This certification demonstrates that the nurse has advanced knowledge and skills in integrating holistic principles into patient care. Holistic nursing emphasizes treating the whole person—mind, body, and spirit—rather than just focusing on specific symptoms or illnesses.
