Hot flashes are nearly synonymous with perimenopause and menopause, and for that reason, many women experience anxiety over them. They are a “hot” topic, and so are discussions about how to relieve them. One natural remedy that has been studied and found to be helpful is Pycnogenol, also known as French maritime pine bark extract.

What is Pycnogenol?

Maritime pine trees (Pinus pinaster), which are native to southwest France, are the source of this remedy that is also known for relieving menopausal symptoms, including hot flashes, as well as symptoms of asthma, poor leg circulation, diabetes, high blood pressure, and prevention of heart conditions. The bark contains chemicals that have shown the ability to reduce swelling, prevent infections, stimulate immune function, and enhance blood flow. Pycnogenol is the trademarked name for the pine bark extract from Pinus pinaster.

Hot flashes and menopause

Hot flashes, also known as vasomotor symptoms, are experienced by approximately 80 percent of women in North America. Declining estrogen levels are behind the development of this uncomfortable and often irritating symptom. The hot flashes occur when the blood vessels near the skin’s surface expand, which causes you to break out in a sweat. Chills and a rapid heart rate can accompany hot flashes.

Can Pycnogenol relieve hot flashes?

Several research studies have demonstrated the ability of Pycnogenol to reduce the symptoms and frequency of hot flashes. Here are a few examples.

In a 2011 study, 38 women with menopausal symptoms were given 100 mg Pycnogenol daily over an eight-week period. Thirty-two women served as controls. Among the symptoms evaluated were hot flashes, night sweats, mood swings, loss of sex drive, irregular periods, and vaginal dryness. At the end of eight weeks, the women who took Pycnogenol had a significant decrease in symptoms while those in the control group didn’t show any changes. Oxidative stress also was significantly lower in the supplement group. (Elevated oxidative stress is associated with declining estrogen levels.) The authors concluded that “Pycnogenol improved the quality of life of most women and these benefits may be at least in part attributed to decreased oxidative stress levels.” 

In another study published several years later, 170 perimenopausal women participated in a double-blind, placebo-controlled trial that lasted three months. The women were randomly assigned to take either a placebo or 30 mg Pycnogenol twice a day. Use of Pycnogenol resulted in a significant improvement in menopausal symptoms, and especially hot flashes and insomnia/sleep problems, both of which were much better after just four weeks and through the end of the study 12 weeks later. 

Using Pycnogenol

Women taking Pycnogenol have had symptom relief with the supplement after doses of 60 mg and 100 mg daily. You should discuss your specific needs with your healthcare provider. 

The use of Pycnogenol has not been found to have an impact on hormone function. Mild side effects associated with Pycnogenol use may include dizziness, headache, and stomach problems.

Bottom line

A bark extract from a French tree may bring much-desired relief from hot flashes among women in perimenopause and menopause. Consult with your healthcare provider about the dose that is right for you.
