Maca root, a plant native to the Andean highlands, has lately garnered international attention. Scientists are not clear that the research supports the numerous claims that are made (Beharry & Heinrich, Journal of Ethnopharmacology, Jan. 30, 2018). Research in animals suggest that it may have effects on the reproductive system (Qureshi et al, Pakistani Journal of Pharmaceutical Sciences, Jan. 2017). However, there are few clinical trials in humans. One reader tried maca root for her hot flashes and found it helpful.
Maca Root for Hot Flashes:
Q. I started having hot flashes during the summer and they were awful. A friend suggested maca root and I decided to try it. It works for me. I take a tablet after breakfast and another at lunch every other day.
Now I can sleep through the night without having to throw the covers off. I am not sure how or why it works for me. I am just glad that it does.
A. Maca root is Lepidium meyenii, a plant that is native to the Andes. Although there is not much scientific research on its benefits for menopausal symptoms, the studies that have been conducted indicate that it may indeed be effective (Depypere & Cohaire, Maturitas, Feb. 2014).
Other Plants That Could Help Hot Flashes:
Black Cohosh:
There are a number of other products that originate in plants that may prove helpful. Black cohosh (sold as Remifemin, among other brands) has garnered support in some studies (Evidence-Based Complementary and Alternative Medicine, online Dec. 23, 2013), but others have called it into question (Gynecological Endocrinology, Sept. 2012; Cochrane Database of Systematic Reviews, Sept. 12, 2012). A recent comparison of black cohosh with evening primrose oil found that black cohosh subdued hot flashes more effectively (Mehrpooya et al, Journal of Education and Health Promotion, March 1, 2018).
Pycnogenol:
Pycnogenol, derived from French maritime pine bark, proved promising in a double-blind placebo-controlled study of 170 women (Journal of Reproductive Medicine, Jan-Feb, 2013). Other studies have also suggested benefits from Pycnogenol (Panminerva Medica, Sept., 2011; Acta Obstetricia et Gynecologica Scandinavica, 2007).
Rhapontic Rhubarb:
In addition, some women have reported benefit from rhapontic rhubarb (Estrovera). There are also some studies demonstrating benefit from this plant extract (Alternative Therapies in Health and Medicine, Nov-Dec, 2008). The extract of this plant, Rheum rhaponticum, appears to work by activating estrogen receptors (Vollmer et al, Chinese Medicine, Feb. 19, 2010).
