What is black cohosh?
Grown in the eastern United States and Canada, black cohosh is a perennial plant with white and feathery flowers belonging to the buttercup family and grows up to 8 feet tall. The roots of this tall woodland plant are popular as a natural herbal remedy.
Several centuries ago, Native Americans used the roots of black cohosh to relieve several female maladies such as menstrual cramps, menopausal symptoms, mood swings, irritability, sleep disturbances, hot flashes, sore throat, cough, arthritis, muscle pain and indigestion. In this regard, the black cohosh plant is regarded as the “woman’s remedy.” Even today, black cohosh is called upon to treat these conditions. The juice of this plant is extracted for making insect repellent and treating snake bites.
Black cohosh and cancer
As it’s being widely used as a woman’s remedy, researchers are having a look on what black cohosh could do for treating cancer, especially as a possible cure for breast cancer.
Based on a systematic review, researchers studied the safety and efficacy of the black cohosh plant among breast cancer patients. The review consisted of 5 clinical and 21 preclinical studies. Generally, the research was determining the effectivity of black cohosh in the associated hot flashes of menopausal women with breast cancer. 1 Hot flashes are the most common symptoms of menopause. They are defined as sudden feelings of warmth which you can feel over your face, neck and chest.
The results were still vague since black cohosh did not seem to have a protective role in cancer prevention. However, in laboratory evidences, the black cohosh showed anti-proliferative properties. Anti-proliferative means the ability to inhibit cancer cell growth. The systematic review also concluded that black cohosh also has potential anti-proliferative effects on prostate cancer cells. But this positive effect on prostate cancer may not be directly related to the estrogenic activity, but more on the apoptotic activity of the black cohosh plant. 1 Apoptotic activity is defined as the ability to induce programmed cancer cell death.
On the other hand, based on a clinical trial among women with breast cancer, the black cohosh plant may have an effect on the estrogen receptors of individual cells which makes it possible to lower breast cancer risk. High levels of estrogen hormone in the body can worsen one’s breast cancer. Though the black cohosh plant seem to have an effect on estrogen receptors, it is not still definite whether it can cure breast cancer. 2
Another study was conducted to investigate the effects of black cohosh in reducing the breast cancer risk of about 2,500 women. Results revealed that black cohosh has such effect. This may be considered as the first known study showing the positive effects of black cohosh against breast cancer. 2
But until more studies are done about the role of black cohosh against breast cancer, breast cancer patients should not use black cohosh as one of their alternative cancer treatments without consulting their health care provider first.
