Benefits of Milk Thistle: Liver and Digestion

Milk thistle (Silybum marianum),

also known as milk thistle, is a plant from the Asteraceae family, rich in silymarin. Among the best-known benefits of milk thistle are liver support and digestive comfort. Its seeds concentrate silymarin, the complex of active compounds at the heart of its properties.

During perimenopause,

the liver is put under strain by hormonal fluctuations, fatigue and a sometimes more unpredictable digestion. Milk thistle is one of the medicinal plants traditionally used to support this period of hormonal transition.

At Jolly Mama,

milk thistle is used in the form of a seed extract standardised to 80% silymarin, ensuring a consistent concentration of active compounds.

Origin and description

Milk thistle is a Mediterranean plant, found across Europe and North America, recognisable by its white-veined leaves.

In traditional lore, these white markings are said to come from the milk of the Virgin Mary — hence its name. It is the seeds, or fruits, that concentrate silymarin, a group of flavonolignans of which silybinin is the main compound. Its traditional use in herbal medicine is long-standing, and milk thistle continues to be studied today for its properties on the liver.

Form matters as much as the plant itself. Milk thistle products are available as mother tinctures, infusions or herbal teas, powders, capsules, or seed extracts, organic or not. To concentrate the benefits of milk thistle, the Silybum marianum seed extract is standardised to 80% silymarin, ensuring a consistent active content from batch to batch — a guarantee of consistency and traceability.

How does it work? (The science bit)

When you consume milk thistle, the silymarin from its seeds is absorbed in the digestive tract, then travels to the liver where it exerts most of its effect. This plant therefore acts right at the level of liver cells.

Its mechanism of action involves silymarin, a complex of flavonolignans studied for its role in supporting the membrane of liver cells and in the face of oxidative stress. Milk thistle is traditionally associated with liver function, the gallbladder and bile ducts, and digestive comfort. The European monograph recognises this traditional use to support liver function and relieve mild digestive complaints such as bloating. Several clinical studies have also measured the effect of silymarin on liver enzymes.

The effects are not immediate: milk thistle works over time, with a regular intake of 250 mg of extract per day. As with any plant, its benefits build up over several weeks, as part of a balanced diet and within your own routine. energy and vitality.

Key takeaway: milk thistle (extract standardised to 80% silymarin, 250 mg) supports the liver and digestive comfort. Its benefits build up over several weeks. It is not recommended during pregnancy or breastfeeding.

Our sources

Milk thistle is traditionally used for digestive comfort, particularly in cases of bloating or slow digestion. The effects vary from person to person and are not immediate, as the plant works gradually. Regular use over several weeks is generally needed to notice any benefit.

During perimenopause, the liver is put under greater demand and digestion may change. Milk thistle supports this transition by helping liver function and digestive comfort. It is used over the longer term, alongside a balanced diet, and integrates well into a perimenopause and menopause.

Milk thistle is generally well tolerated. Some mild digestive discomfort, such as looser stools, may occur at the start of use. People who are allergic to plants in the Asteraceae family, such as mugwort or ragweed, should exercise caution. As with any supplement, it is best to stick to the recommended dose.

Milk thistle is not recommended during pregnancy and breastfeeding, due to insufficient data. It may cause drug interactions, as silymarin influences liver metabolism. If you are currently on medication, have gallstones, or are in any doubt, seek advice from a healthcare professional before starting.
