An editorial reports that with regard to specific supplements, the analysis found that individual phytoestrogens such as dietary and supplemental soy isoflavone were associated with improvements in daily hot flushes, and vaginal dryness score. In contrast to this, black cohosh (a popular herbal remedy) was not associated with changes in the number of hot flushes according to data from four trials. Only one study assessed the association of black cohosh with the number of night sweats, but this also reported no difference. Similarly, no association was found between the red clover herb and the number of hot flushes in 24 hours. Although, one study found a decrease in the frequency of night sweats with red clover. The study also looked at Chinese herbs and found results of RCTs inconsistent, although in general these showed no beneficial effect on menopausal symptoms. Newer herbal remedies such as Err731 (an extract isolated from the “false rhubarb” plant, Rheum rhaponticum) and pycnogenol (an extract from pine bark), reported improvements in the number of hot flushes in 24 hours. The researchers said that more research is needed on these products because the evidence remains limited.
