Researchers at Georgetown University Medical Center (GUMC) conducted the study on four groups of rats over a period of 10 days. The first group was stressed and received acupuncture at a spot known as 'Zusanli'.
The second group was stressed and received a sham acupuncture treatment near the tail, the third group was stressed but did not receive any acupuncture while the control group was not stressed or received acupuncture. The researchers found that that the group that received the real acupuncture treatment displayed clinical benefits of hormone related stress reduction.
"Many practitioners of acupuncture have observed that this ancient practice can reduce stress in their patients, but there is a lack of biological proof of how or why this happens. We're starting to understand what's going on at the molecular level that helps explain acupuncture's benefit", lead researcher Ladan Eshkevari said.
