I am a medical doctor, author, board certified anesthesiologist, clinically certified aromatherapist, professional speaker and the oilMD. Dr Geiger promotes wellness through nature on the web and in the hospital because there are many integrative medical and natural solutions to health care issues. That is one reason why I have introduced the clinical uses of aromatherapy and essential oil therapy into hospitals, surgery centers, as well as operating and recovery rooms. For example, the essential oil of ginger prevents and treats post-operation nausea (PONV) and increases patient satisfaction. Ginger works for all forms of nausea.
