It depends on your doctor.  There are all kinds. 

Mrs. has one that's trained in Western Medicine who also uses holistic methods where reasonable.  The two are not opposites, neither are they completely incompatible.

Mine is more entrenched in Western Med, but accepts that his patients may choose other options.  He also outlines the details, known and unknown.  He doesn't judge.  He just provides the info and monitors the patient.
