In this article we will find out everything you need to know about milk thistle, its health benefits, uses and recommended dosages.

What is milk thistle

Milk thistle is a plant belonging to the Asteraceae family, native to the Mediterranean basin.
It is a biennial or perennial herbaceous plant characterized by dark green leaves and showy whitish spines.
Its inflorescences consist of purplish flower heads. The active ingredients of milk thistle are mainly contained in its seeds.

The bioactive substances extracted from milk thistle seeds are called silymarin . Silymarin is a complex of flavonolignans and includes:

  • Silibina
  • Isosilybin
  • Silidianin
  • Silicristine

Silymarin is responsible for most of the health benefits attributed to milk thistle.

Health benefits of milk thistle

Numerous scientific researches have shown that milk thistle possesses several health-promoting properties, including:

  1. Liver protection:
    Silymarin has been shown to have hepatoprotective properties, helping to regenerate damaged liver cells and prevent fat accumulation in the liver.
  2. Antioxidant activity:
    Milk thistle acts as a powerful antioxidant, protecting cells from free radical damage and reducing oxidative stress.
  3. Immune system support:
    Silymarin can improve immune system function, helping to prevent and fight infection.

Some studies also suggest that milk thistle may have beneficial effects on other conditions, such as diabetes, dyslipidemia, and metabolic syndrome, but more research is needed to confirm these effects.

    Silymarin can help protect the skin from free radical damage and promote wound healing.
