Homoeopathy is about restoring health to the whole person. Therefore in a consultation all aspects of the person are addressed, not just the physical symptoms. The homeopath will encourage you to talk about your life situation and medical history.
Disease labels are not always helpful in homoeopathy; it is the underlying disease process that is going on within the patient that is most important. Thus people, who are not suffering from any recognised illness, can be helped with homoeopathy.
