This plant grows in Europe and North America. The flowering tops are used in botanical medicine. Another plant, white clover, grows in similar areas. Both have white arrow-shaped patterns on their leaves.
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

Traditional Chinese Medicine and Western folk medicine used this plant as a diuretic, a cough expectorant (an agent that promotes discharge of mucus from the respiratory passages), and an alterative. Alterative plants were considered beneficial for chronic conditions, particularly those afflicting the skin.
Red clover is known as an alterative agent—in other words, one that produces gradual beneficial changes in the body, usually by improving nutrition; also known as a “blood cleanser.” It is a traditional remedy for psoriasis and eczema. However, the mechanism of action and constituents responsible for red clover’s purported benefit in skin conditions are unknown.
Modern research has revealed that red clover also contains high amounts of isoflavones, such as biochanin A, formononetin, and genistein, which have weak estrogen-like properties. Modern research has focused on a red clover extract high in isoflavones as a possible treatment for symptoms associated with menopause and cardiovascular health in menopausal women. In a double-blind study, administration of 80 mg of isoflavones per day from red clover reduced the frequency of hot flashes in postmenopausal women. The benefit was noticeable after 4 weeks of treatment and became more pronounced after a total of 12 weeks. Another double-blind trial found that red clover improved cardiovascular function in menopausal women. Various laboratory studies suggest red clover isoflavones may help prevent prostate cancer. In a case study, use of red clover by a man with prostate cancer led to noticeable anticancer effects in his prostate after the cancer was surgically removed. Although the isoflavones in red clover may help prevent certain forms of cancer (for example, breast and prostate), further studies are needed before red clover is recommended for cancer patients.
Traditionally, red clover is taken as a tea, by adding 1 cup (250 ml) of boiling water to 2 to 3 teaspoons (10 to 15 grams) of dried flowers and steeping, covered, for ten to fifteen minutes. Three cups (750 ml) can be drunk each day. Red clover can also be used in capsule or tablet form, equivalent to 2 to 4 grams of the dried flowers. Also, 1/2 to 3/4 teaspoon (2 to 4 ml) of tincture three times per day may be taken. Standardized extracts providing 40 mg isoflavones per day are available as well.
