Effects of Black Cohosh on Menopausal Hot Flashes
A Phase 2 study testing Black Cohosh in people with Postmenopause and Hot Flashes, run by National Center for Complementary and Integrative Health (NCCIH) at 1 site in United States.
Trial summary
This study will assess whether treatment with black cohosh is effective in reducing the frequency and intensity of menopausal hot flashes. In addition, this study will determine whether or not black cohosh reduces the frequency of other menopausal symptoms and improves quality of life. Read more about this study

About this study
This study will assess whether treatment with black cohosh is effective in reducing the frequency and intensity of menopausal hot flashes. In addition, this study will determine whether or not black cohosh reduces the frequency of other menopausal symptoms and improves quality of life.
Read the detailed description
Most American women will spend the last third of their lives post-menopause. During this time, chronically low levels of steroidal estrogens may lead to a number of short and long-term medical sequelae such as hot flashes, vaginal dryness, heart disease, and osteoporosis. While some physicians believe that demonstrated beneficial effects of estrogen, particularly on the cardiovascular and skeletal systems, warrant the taking of hormone therapy from menopause on, many women choose not to take estrogen replacement therapy (ERT) and are increasingly exploring alternative approaches to ERT.
For centuries, black cohosh (Cimicifuga racemosa) has been used worldwide for women's health. Despite its long-standing use, studies of black cohosh have yielded conflicting data, in part because of lack in study design rigor and the short duration of studies to date. The primary aim of this study is to correct past shortcomings in study design to determine whether treatment with black cohosh is effective in treating menopausal symptoms.
Participants in this study will be given black cohosh for a 12-month period. Potential mechanisms of action of black cohosh will be examined by quantifying the levels of sex hormones, including estradiol, estrone, FSH, and LH. Because black cohosh may act as an estrogenic agent, the effect on endometrium will be evaluated by sonogram and by monitoring the incidence of adverse events and compliance with the study.

Where is the study taking place?
The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Aug 2006.
