Women approaching menopause know about hot flashes.

Hot flashes are one of 11 menopausal symptoms that can last for years.1-3

While menopause occurs at age 51 on average,4 a recent study found many women aged 60 to 65 are still experiencing moderate to severe menopausal symptoms.5

Another study found that only about 10% of women suffering menopausal symptoms are receiving treatment.6

Some women think nothing can be done. Others are concerned about the potential side effects of conventional hormone replacement therapy, including a possible increased risk of breast cancer, stroke, and clotting.7

But there is no need for women to suffer in silence anymore. Scientific evidence shows that menopausal women can safely benefit from an extract of Siberian rhubarb, a readily available plant extract that does not require a prescription.

Multiple clinical studies have demonstrated that Siberian rhubarb extract alleviates all 11 recognized menopausal symptoms by as much as 83%, often within just four weeks.8-12

For women who prefer to avoid hormone-based treatments, these findings point to a natural, safe, and effective way to restore well-being during menopausal years and beyond.

The 11 Menopause Symptoms

While hot flashes and night sweats are the most well-known menopause symptoms, many women suffer from an array of others.

The Menopause Rating Scale, or MRS, was developed in 2004 as a way of evaluating all of these symptoms.

It allows women to rate 11 separate symptoms, graded in severity from 0 (the symptom is not present) to 4 or to 5 (“very severe”) on the revised MRS II scale.2,3,9

The 11 potential menopause symptoms are:

  • Hot flashes/sweating,
  • Heart discomfort,
  • Sleep problems,
  • Depressive mood,
  • Irritability,
  • Anxiety,
  • Physical and mental exhaustion,
  • Sexual problems,
  • Vaginal dryness,
  • Bladder problems, and
  • Joint and muscle discomfort.

Having even one of these symptoms can lead to a significantly lower quality of life.

What You Need to Know

Menopause Relief

  • Multiple, controlled, clinical studies have demonstrated that Siberian rhubarb extract substantially reduces the 11 most important menopausal symptoms, including hot flashes and sleep problems, without any significant safety issues.
  • Siberian rhubarb extract has been used in Germany since 1993 to safely treat menopause symptoms.
  • Women taking Siberian rhubarb extract can expect broad improvements in mood-related menopause symptoms, including depression and irritability, that are not well-treated by conventional therapies.

How Siberian Rhubarb Works

Most symptoms of menopause are caused by a sharp drop in levels of the hormone estrogen.

That’s where Siberian rhubarb comes in. The root of this plant is rich in compounds that bind to cell receptors that normally bind to estrogen.9,10,13

By doing this, they trigger beneficial estrogen-like effects throughout the body, helping to relieve menopause symptoms.

Siberian rhubarb extract has been successfully used in Germany since 1993 for treating menopause symptoms.10 To further validate its benefits, scientists conducted a series of controlled, clinical trials to determine the extract’s effectiveness.

Easing All 11 Menopause Symptoms

First, a research team enlisted 109 women who were suffering from multiple symptoms of perimenopause, a stage just before menopause when the ovaries gradually begin to make less estrogen. In this study, women received either a daily placebo or 4 mg of Siberian rhubarb extract.9,11

After 12 weeks, scientists evaluated the women by using the MRS II, a respected scale which rates menopause symptoms. The researchers documented a 54% decrease in total symptom scores and significant improvements in all 11 symptom categories. There were no significant changes among the subjects receiving a placebo, who continued to experience all the same menopause symptoms.9

A similar study of 112 perimenopausal and symptomatic women found virtually identical results. After 12 weeks, patients receiving a placebo had no significant changes. But women getting 4 mg of Siberian rhubarb extract daily showed:12

  • A decrease of 54% in overall MRS scores,
  • Significant improvements in all MRS symptom categories, and
  • An 83% reduction in the median number of daily hot flashes.

By comparison, conventional hormone therapy was found, in a review of 24 placebo-controlled trials, to reduce the frequency of hot flashes by about 75%.14 In other words, Siberian rhubarb extract improved hot flashes as much as, or even more than, conventional treatment.

Studies Confirm Long-Term Benefits

Next, investigators set out to validate these results with a larger group over a longer period.

A total of 252 women took part in a study that lasted six months. Notably, this group included women ranging from perimenopausal to postmenopausal, all of whom had concerning symptoms.10

Each of the women took 4 mg of Siberian rhubarb extract daily, and at the end of the study, each of the 11 MRS symptoms was significantly reduced. There was also a 52% decrease in overall MRS (Menopause Rating Scale) scores.10

The study team found that women with the most severe symptoms achieved the greatest overall improvements. In general, the most commonly improved symptoms were:10

  • Hot flashes/sweating,
  • Sleep problems,
  • Irritability, and
  • Depressed mood.

But menopause symptoms can last for years. So researchers set out to study whether this extract would be effective over a significantly longer term.

For a period of 96 weeks scientists conducted a follow-up study.8 Women who had been taking the Siberian rhubarb in a previous, double-blind clinical trial were asked to continue supplementing, while the previous placebo group was asked to now start taking the Siberian rhubarb extract.

After switching to the Siberian rhubarb, the former placebo group rapidly caught up to the supplementing test group. At the end of 96 weeks, they demonstrated identical results of a median 83% decrease in total MRS II scores. What’s more, hot flashes decreased from about 15 a day to an average of less than 1.4 a day.8

Improving Mood

Some of the most troubling menopause symptoms are mood-related: depression, anxiety, and irritability.

Although conventional hormone treatments address hot flashes and night sweats, they have not proven effective for improving mood symptoms. In fact, some evidence suggests they may even aggravate them.7,15

Not Siberian rhubarb.9,12 In a randomized, controlled clinical trial, the extract led to a resolution of or improvement in depressed mood in more than 90% of those taking it.11

The group receiving the extract in this study also achieved a 66% reduction in total scores on the Hamilton Anxiety Scale.11

Why It’s Safe

No relevant safety issues arose in any of the above studies of Siberian rhubarb extract, which involved more than 400 women in total.

No changes were seen in vital signs, or in breast, vaginal, or endometrial tissues.8-10,12 And from 1993-2014, an average of 6.7 million doses of this extract were sold in Germany every year.16

The remarkable safety record of Siberian rhubarb appears to be rooted in the fact that this unique extract preferentially binds to beneficial receptors (ER-beta) while binding only weakly to undesirable receptors (ER-alpha).13,17

Within the body, there are two types of cell receptors to which estrogen normally binds:

Estrogen receptor-alpha (ER-alpha)

and

Estrogen receptor-beta (ER-beta).

When estrogen lost during menopause is replaced by non-selective hormone drugs, both ER-alpha and ER-beta receptors are activated.18

The problem is that these two receptor types tend to be concentrated in different body tissues, and activating them leads to very different results.

Activating ER-beta receptors promotes beneficial estrogenic effects on skin, brain, bone, cardiovascular, and other tissues.

But activating ER-alpha receptors can produce undesirable growth in reproductive tissues, including initiating and promoting cancer. In fact, increased activity of the ER-alpha receptor is believed to cause the ill effects of conventional hormone therapy.18

When scientists performed lab studies with Siberian rhubarb, though, they discovered that its desirable activation of ER-beta receptors is 13.5-fold greater than its undesirable activation of ER-alpha receptors.13,17

When compared to other known natural compounds or even to natural estrogen itself, this standardized extract has the highest selectivity for ER-beta over ER-alpha.13,17

Summary

Siberian rhubarb extract is a unique approach to controlling menopausal symptoms, and provides an alternative to hormone replacement therapy.

In clinical studies, including large, long-term trials, a daily dose of just 4 mg of Siberian rhubarb extract significantly relieved the 11 most important menopausal symptoms, including hot flashes, exhaustion, bladder problems, and more.

Bioidentical hormone-replacement therapy can be effective for many women for hot flashes. But rhubarb extract provides an effective option for those interested in broad, non-hormonal relief of all known menopausal symptoms.

These clinical trials with Siberian rhubarb extract show a notable improvement in mood symptoms like depression, a benefit conventional hormone therapy does not provide. And this plant extract has been demonstrated to be safe.
