Intuition is one source of common sense. It can also help in induction to gain empirical knowledge. Sources of intuition are feeling, experiences and knowledge.

In alternative medicine, a medical intuitive is a person who alleges to have learned to apply their intuition to the field of medical diagnosis. There are numerous medical professionals, health care workers, scientists and others who are skeptical of the claims of such abilities.

Medical intuition as a field was initiated primarily by Caroline Myss a Ph.D. in “intuition and energy medicine”. Medical intuitives claim to be able to view many physical problems in a person’s aura before any physical signs of illness can be detected. Areas of illness are said to frequently appear to medical intuitives as dark, grainy, or sticky energy.
