Milk Thistle (Silybum marianum)

Milk thistle is a major constituent of Denes Milk Thistle+ Powder


Milk thistle, which is known by several other names including St Mary’s thistle and Holy thistle, is a tall prickly plant which is native to the Mediterranean region but which now grows worldwide. Growing up to a maximum height of 10 feet, it has wide leaves which have white veins or blotches. The flowers are reddish-purple in colour and produce hard skinned fruits which contain seeds that look very similar to sunflower seeds. The seeds contain the medicinally active part of the plant and are frequently used to help both liver and gall bladder problems. In the past however, as its name might suggest, the plant was also used to promote the production of milk in breastfeeding mothers.


Sometimes Milk Thistle is referred to as Silymarin. This is actually a mixture of the herb’s active components, including Silybinin which is sometimes also called Silibinin or Silybin. The seeds contain other substances including flavones, a compound called silydianin, an essential oil, various bitter substances and mucilage.


Milk thistle acts primarily on the liver and the gall bladder. It can be used to help with hepatitis (inflammation of the liver), cirrhosis (fibrosis) of the liver and inflammation of the gallbladder (cholecystisis). It is also thought to protect the liver from the damaging effect of poisons and toxins as well as helping to regenerate damaged cells. Other research has shown that it may have some action in lowering cholesterol levels. It can help where there is a low tolerance of dietary fats and it may be of benefit in reducing the growth of cancer cells in certain types of cancers.
