Auricular acupuncture (AA) can help improve vascular parameters in patients with diabetics’ feet, according to Brazilian researchers.  Forty-four individuals with type 2 diabetes were randomly assigned to two groups: an intervention group that received five sessions of auricular acupuncture, and a control group which did not receive any therapy.  Patients who received AA were observed to have significantly increased lower limb blood circulation and raised plantar temperature compared with those in the control group.
