Treating Hypertension with Acupuncture and Chinese Medicine
Posted by davidscrimgeour on September 1st, 2015
Elevated blood pressure is a major health problem affecting as many as a third of the US population over 60. Studies estimate that 62% of stroke, 49% of ischemic heart disease and 14% of other cardiovascular diseases can be attributed to hypertension. The problem with high blood pressure is that too much force is exerted on the arteries as blood is pumped through the body. This results not only in eventual damage to the blood vessels themselves but to other organs as well.
To assess blood pressure, both systolic and diastolic pressures are measured. Systolic represents the maximum pressure exerted in the arteries as the heart contracts, and diastolic is the minimum pressure in those vessels between cardiac contractions. Although blood pressure will often rise slightly as a person ages, blood pressure is considered normal if the top number (systolic pressure) is between 90 and 120 and the bottom number (diastolic) is between 60 and 80 mm Hg.
Although there are several causes of hypertension including aging, recent studies have shown that an overactive sympathetic nervous system is one of the major causes of high blood pressure. When the sympathetic nervous system becomes over-stimulated, it causes vasoconstriction of the arteries of the heart. And long-term vasoconstriction can lead to blood vessel damage, stroke and damage to the vital organs of the body.
High blood pressure is managed in Western medicine with several types of anti-hypertensive drugs. Diuretics help the kidneys remove salt and water which lowers the volume of blood in the vessels. Beta-Blockers make the heartbeat more slowly so blood passes though the vessels with less force. ACE Inhibitors prevent the body from making angiotension II which tightens blood vessels so that blood vessels remain relaxed, lowering overall pressure. Calcium Channel Blockers or CCBs, prevent calcium from entering the muscle cells in the heart and blood vessels which slows the heart rate and keeps the vessels from tightening. Vasodilators relax muscles in blood vessel walls and blood flows more easily. While effective at lowering blood pressure, all of these drugs have side effects that range from a chronic dry cough to headaches, dizziness, fainting, weight gain, insulin resistance, depression, and erectile dysfunction.
So what are the best natural ways to lower blood pressure?
Boulder acupuncturist, David Scrimgeour, L.Ac. maintains that many cases of hypertension can be treated successfully with acupuncture and Chinese medicine. “Acupuncture can lower blood pressure by down-regulating the sympathetic nervous system and by bringingthe body back into homeostasis,” says Scrimgeour.“Many of my patients are able to have normal blood pressure using acupuncture, Chinese herbal formulas and by making dietary and lifestyle changes. And with these changes, patients see remarkable improvement in their overall health and vitality as well.”
A recent study conducted at the University of California at Irvine in August 2015 concluded that acupuncture combined with electro-stimulation can lower blood pressure rates by as much as 50%. According to Dr. John C. Longhurst, director of the Samueli Center, "This study suggests that acupuncture can be an excellent complement to other medical treatments, especially for those treating the cardiac system.”There have also been studies showing that acupuncture outperforms Captopril, a commonly prescribed ACE inhibitor for high blood pressure. One of these studies concluded that electro-acupuncture was significantly more effective than the Western medication at controlling blood pressure. A German study comparing true acupuncture to antihypertensive medications concluded that blood pressure reductions with acupuncture are comparable to monotherapies with ACEinhibitors.
Scrimgeour explains that one of the mechanisms by which acupuncture lowers blood pressure is by down-regulating the sympathetic nervous system. Electro-acupuncture activates neurons in the brain which inhibit SNS activity by stimulating the opioid system which includes endorphins and encephalin. It also inhibits nociception which involves the encoding and processing of harmful stimuli in the nervous system. By inhibiting nociception and increasing the release of endorphins, the parasympathetic nervous system takes over which relaxes the body and lowers blood pressure.
In addition to acupuncture, David Scrimgeour also uses several Chinese herbal formulas such as Bupleurum&Dragonbone and Gambirto help control hypertension.“These formulas work by calming an up-regulated sympathetic nervous system which is often a contributor to hypertension,” says Scrimgeour. He also recommends the following dietary and lifestyle changes with his patients: 1) engaging in regular exercise including some cardiovascular exercise; 2) reducing grains and carbs in one’s diet and increasing fresh organic vegetables and fruits; and 3) supplementing with Vitamin C and Omega 3s. Finally, he recommends reducing stress levels with meditation, yoga or Tai Chi.
