How Acupuncture Regulates Blood Pressure
Acupuncture regulates blood pressure by exploiting a complex system known as the neuroendocrine system, which is composed of the endocrine system (primarily the hypothalamus, pituitary, and thyroid / adrenals), and the intricate working relationship it has with the nervous system. The endocrine system regulates hormones and metabolism. The autonomic nervous system (ANS) is divided into two arms, a sympathetic branch (fight or flight), which plays a role in helping regulate the vascular tone and blood volume of the heart; and a parasympathetic branch (rest and digest), that regulates body processes like blood pressure and breathing.
The central nervous system (CNS) is a two – way communication network consisting of the brain and spinal cord, which processes all the information from the body and external stimuli. Information is collected by the nervous system, relayed through the spinal cord to the brain, and then the brain sends signals to the body through the same mechanism.
In terms of research, there is an ongoing accumulation of data on the regulatory effect of acupuncture on the endocrine system, and how it can restore balance
ver the last decade, there has been an increase in neuroimaging studies on the effects of acupuncture on brain centers due to advancements in imaging technologies. In one study, electro acupuncture was used to activate specific parts of the brain eliciting a hypotensive effect via the (CNS).
Recent investigations have indicated that one of the major contributors to high blood pressure is an overactive sympathetic nervous system (SNS). When the (SNS) becomes over-stimulated or dominant, it can cause vasoconstriction of the arteries in the heart; thereby inducing a hypertensive state. The latest studies show that one of the mechanisms by which acupuncture lowers blood pressure is by down – regulating the (SNS). One such study found that electro acupuncture activates neurons in the brain, which inhibits (SNS) activity by stimulating the opioid system (endorphins,
There have also been studies showing that acupuncture outperforms Captopril, a commonly prescribed angiotensin – converting enzyme inhibitor (ACE – inhibitor) for high blood pressure. One of these studies that compared electro acupuncture to Captopril 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 ACE – inhibitors.
What are Acupoints?
When treating hypertension, we select a specific combination of acupoints, which vary depending on the particular clinical presentation of hypertension and any underlying causes. We have many options to choose from on either the front or back side of the body, distal points on the extremities, as well as, points on the ears. When we choose back points,
Jueyinshu – BL 14
- Regulates the heart
- Unbinds the chest
- Regulates & descends Qi
Xinshu – BL15
- Tones and nourishes the Heart
- Regulates Heart Qi
- Calms the spirit (spirit being the (SNS))
- Unbinds the chest and resolves blood stasis
- Clears Heart fire
Cure with Eastern Medicine
Eastern medicine is a dynamic system of medicine, which includes numerous forms and variations of treatments that the practitioner can choose from. For this reason, treatment protocols for blood pressure will vary from one practitioner to another depending on the disease presentation, and the style and perspective of the practitioner. Generally speaking, herbal therapy takes precedence in most treatment plans and acupuncture is used as an adjunct. This is because herbs
For any treatment to be truly effective, no matter what the cause of high blood pressure is, it requires great effort by the patient to make lifestyle modifications that will promote a heart healthy future. This includes:
- Changes in diet & nutrition
- Physical exercise (approved by your acupuncturist / physician)
- Light exercise (Tai Chi, Qigong, yoga, meditation)
- Quality sleep
