Jennifer McGrath, L.Ac., Dipl.OM shared in a recent newsletter that Raynaud’s syndrome, also known as Raynaud’s disease, causes a sudden constriction of the vessels supplying blood to the skin, largely affecting the fingers and toes. The symptoms, commonly known as an attack, may be triggered by cold temperatures or emotional stress. Most cases are mild and can be treated with lifestyle changes such as wearing warm gloves and socks, and avoiding rapid temperature changes. While not life-threatening, in rare cases, when left untreated, the affected tissue may become necrotic and gangrenous.
According to a small 1997 study published in the Journal of Internal Medicine, acupuncture is effective in treating primary Raynaud’s syndrome. The patients that received acupuncture experienced a statistically significant decrease in the frequency, severity and duration of their vasospastic attacks. The patients in the control group showed no improvements. Researchers concluded acupuncture was safe and effective for treating the symptoms of primary Raynaud’s syndrome.
As a cold environment or object is often responsible for triggering an attack, this may indicate a Yang deficiency. When Yang energy is low, blood circulation may slow down as a result. Symptoms of Yang deficiency include feelings of cold, lower back or knee pain and a weak pulse. Treatment in this case would focus on boosting Yang energy, circulation and the immune system.
