WASHINGTON (Reuters) - A specialized acupuncture treatment that
uses low levels of electrical stimulation can lower blood pressure dramatically
in rats, U.S. researchers reported on Monday.
"This study suggests that acupuncture can be an excellent
complement to other medical treatments, especially for those treating the
cardiac system," said Dr. John Longhurst of the University of California,
Irvine, who led the study.
"The Western world is waiting for a
clear scientific basis for using acupuncture, and we hope that this research
ultimately will lead to the integration of ancient healing practices into modern
medical treatment."
Writing in the March issue of the
Journal of Applied Physiology, Longhurst and colleagues said they inserted
acupuncture needles at specific points on the front legs of rats with
artificially elevated blood pressure rates.
This is equivalent to the inside of
the forearms, slightly above the wrists in people.
Acupuncture alone had no effect on
blood pressure in the rats, Longhurst's team found. But adding electrical
stimulation at low frequencies lowered the blood pressure, although it did not
bring it to normal.
The effects lasted for up to two hours.
"This type of electroacupuncture is only effective on elevated blood pressure
levels, such as those present in hypertension, and the treatment has no impact
on standing blood pressure rates," said Longhurst, a cardiologist .
"Our goal is to help establish a standard of acupuncture treatment that can
benefit everyone who has hypertension and other cardiac ailments."
