Acupuncture significantly reduces levels of a protein in rats linked to chronic stress, researchers at Georgetown University Medical Center (GUMC) have found. They say their animal study may help explain the sense of well-being that many people receive from this ancient Chinese therapy.

Published online in December in Experimental Biology and Medicine, the researchers say that if their findings are replicated in human studies, acupuncture would offer a proven therapy for stress, which is often difficult to treat.

“It has long been thought that acupuncture can reduce stress, but this is the first study to show molecular proof of this benefit,” says the study’s lead author, Ladan Eshkevari, Ph.D., an assistant professor at Georgetown’s School of Nursing & Health Studies, a part of GUMC.

She found NPY levels in the experimental group came down almost to the level of the control group, while the rats that were stressed and not treated with Zuslanli acupuncture had high levels of the protein.

In a second experiment, Eshkevari stopped acupuncture in the experimental group but continued to stress the rats for an additional four days, and found NPY levels remained low. “We were surprised to find what looks to be a protective effect against stress,” she says.
