Association of Auricular Reflective Points and Status of Type 2 Diabetes Mellitus: A Matched Case-Control Study

The reflexive property of the ear can cause various physical attributes to appear on the auricle in the presence of bodily disorders. The association of auricular signals (presence or absence of discoloration, marks after pressing, tenderness, and electrical resistance) and diabetes mellitus (DM) should be further investigated because auricular diagnosis is an objective, painless, and noninvasive method that provides rapid access to information. A matched case-control study on 282 subjects was conducted. Cases (n=141) were defined as those diagnosed with type 2 DM (T2DM). Every subject in the case group was matched with the control by age and gender. Ear diagnosis was conducted in three aspects: inspection, electrical detection, and tenderness testing. Results suggest that the tenderness and electrical conductivity of some auricular points, including “pancreas and gallbladder,” “endocrine,” “kidney,” “lower tragus,” “heart,” and “eyes,” were associated with T2DM status in Chinese population. In the subgroup analyses, certain auricular signals were also associated with glycemic control, disease duration, and related complications. Auricular diagnosis could be considered as a screening method for vulnerable populations with T2DM risk. Thus, appropriate interventions can be implemented to prevent or delay the progression of T2DM.

Auricular Diagnosis and Therapy for Alopecia: Patient Data Analysis

It has been reported that tenderness at a specific point on the ear indicates pathology at a corresponding area of the body. The author has used this relationship to investigate patients with alopecia and to provide a rapid indication for the cause of their hair loss. Where possible this diagnosis was confirmed by conventional investigation. It was found that out of 521 patients examined, almost every one had a different combination of tender ear points, but that different specific groups of ear points were found routinely in the majority of patients in each of three categories of alopecia. The author suggests that when auricular acupuncture is used to treat alopecia, points should be selected from the tender spots found, rather than from a standard list of recommended points.
