Red Clover (Trifolium pratense)
Parts used and where grown: 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 interesting white arrow-shaped patterns on their leaves.
In what conditions might red clover be supportive?
cancer risk reduction, cough, eczema, blood purifier
Historical or traditional use: Traditional Chinese medicine and western folk medicine used this plant for similar purposes. It was well regarded as a diuretic, to stop coughing, and as an alterative.1 Alterative plants were considered beneficial for all manner of chronic conditions, particularly those afflicting the skin.
Active constituents: Red clover contains isoflavone compounds, such as genistein, which have weak estrogen properties.2 Various laboratory studies show that these isoflavones may help prevent cancer.3 Although the isoflavones in red clover may help prevent certain forms of cancer (e.g., breast and prostate), more clinical studies must be completed before red clover is recommended for cancer patients. The mechanism of action and responsible constituents for its purported benefit in skin conditions is unknown.
How much should I take? Usually red clover is taken as a tea, by adding 250 ml (1 cup) of boiling water to 2-3 U.S. teaspoons (10-15 grams) of dried flowers and steeping, covered, for ten to fifteen minutes. Three cups can be drunk each day. Red clover can also be used in capsule or tablet form in the amount of 2-4 grams of the dried flowers or 2-4 ml of tincture three times per day. Dried red clover tops are also available in capsules, tablets, and tinctures.
Are there any side effects or interactions?
Non-fermented red clover is relatively safe. However, fermented red clover should be avoided altogether.
