Biofield is the term that refers to an energy field that many people believe to possess around the body. Biofield has been a widely used concept in alternative medicine practitioners, especially energy medicine, as a system that directly interferes with physical, mental and spiritual health. In addition, many still believe that a person's biofield can interfere with other people's health, coexistence, and spirituality.
Biofield can be compared to aura, however aura has more philosophical and spiritual concepts.
