Stop hot flashes and night sweats with this natural remedy.
Clinical studies have confirmed the effectiveness and safety of a special herbal extract of the plant Rheum rhaponticum L, called ERr 731, for the relief of menopausal symptoms, particularly hot flashes.
Research on herbs and the use of herbal remedies is far more accepted in Europe than in the United States. In Germany, research on herbal remedies for relief of menopausal symptoms has been ongoing since the 1940's.
Health practitioners in Germany have been using a special extract of Siberian Rhubarb (called ERr 731) to provide relief for the symptoms of menopause since 1993.
What is ERr 731?
Several clinical studies have demonstrated the benefits and safety of ERr 731 for relief of menopausal symptoms. The extract contains no estrogen.
It is composed of phytoestrogens, which are plant chemicals that generally have very mild estrogenic activity, in the range of 1/1000 that of estrogen. The phytoestrogens that are extracted from Siberian Rhubarb in ERr 731 are unique to the plant.
The phytoestrogens in Siberian Rhubarb root are in a class called hydroxystilbenes. These phytoestrogens are chemically different from other classes of phytoestrogens such as those found in soybeans, red clover, flax and hops.
The hydroxystilbene phytoestrogens in this extract are similar in structure to resveratrol which has received a lot of recognition for its health benefits.
Relief of hot flashes and other perimenopausal and menopauseal symptoms...
Several clinical studies have documented the benefit ERr 731 extract for relief of menopausal symptoms.
Siberian Rhubarb root extract (ERr 731) Clinical Study:
In this study of 109 perimenopausal women, 54 women were given Siberian Rhubarb extract (ERr 731) and 55 women were given a placebo.(3,5) The group of women receiving ERr 731 experienced significant relief of 11 menopausal related symptoms compared to the group of women who received none.
The women who took Siberian Rhubarb extract experienced significant decrease in the severity and number of hot flashes by the end of 4 weeks.
At the end of 12 weeks the women taking Siberian Rhubarb root extract reported relief of 11 common menopausal complaints including
- hot flashes and sweating heart complaints
- sleep disturbances
- depressive mood
- irritability
- anxiety
- physical and emotional exhaustion
- sexual problems
- urinary tract complaints
- vaginal dryness
- joint and muscle complaints
The above study reported by Herger, et al. in the medical journal Menopause (2006) showed that Siberian Rhubarb root extract reduced hot flashes by 72% in just 12 weeks.
Based on the results of this and three additional clinical studies of rhubarb root extract, on average women reported 11 fewer hot flashes per day after 12 weeks.
Safety of Siberian rhubarb root extract...
Studies of Siberian Rhubarb extract have shown it to be safe and non-toxic. When very high doses of the extract (14,000 X the weight adjusted recommended dose for humans) were given to dogs and rats in two clinical studies, no adverse effects were found.
Four different clinical studies have observed the benefits of the ERr 731 extract as well as its safety. These clinical studies showed that the ERr 731 extract was tolerated well by over 400 women for up to two years.
Women in these studies had no negative side effects from the extract. They did not have any relevant changes in endometrial biopsies (biopsies of the lining of the uterus), no bleeding, no changes in weight, no changes in blood pressure or pulse rate, or in lab tests.
