Red clover is a relatively controversial herb. It is botanically known as Trifolium pratense and more affectionately referred to as red clover, purple clover, wild clover, cleaver grass or marl grass.

It belongs to the Leguminosae plant family growing in meadows throughout Britain, Europe, Central and Northern Asia, from the Mediterranean the Arctic. Physically it is distinguishable by its smooth elegant leaves which taper to a point, and its clusters of reddish-purple flowers. These flower heads have been widely reported to hold the ingredients that have brought the plant medicinal fame – and these ingredients include four varieties of isoflavones.
These isoflavones have been reported to have mild oestrogenic activity, accounting for the herb’s reputation for relieving menopausal symptoms. It is important to note, however, that scientific evidence supporting the successful administration of red clover for this purpose is scarce, and a variety of other plants, like soy, are considered superior sources for such isoflavones.
In addition to these claimed benefits, red clover has also been used to treat jaundice, inflammation, coughs, cardiovascular disease and even cancer. It is also believed to purify the blood.
Numerous clinical studies are underway and promise to reveal the true medicinal qualities and benefits of this herb in the near future.
