" allopathic medicine is very good at managing trauma, acute bacterial infections, medical and surgical emergencies, and other crises. It is very bad at managing viral infections, chronic degenerative disease, allergy and autoimmunity, many of the serious kinds of cancer, mental illness, “functional” illness (disturbances of function in the absence of major physical or chemical changes), and all those conditions in which the mind plays an active role in creating susceptibility to disease.
