How Does Milk Thistle Benefit You?

Milk thistle works by flushing out the toxins in the body, which can otherwise cause issues like liver cirrhosis, kidney stones, diabetes, ill effects of chemotherapy, etc.

The other important nutrients in milk thistle, like vitamin E, fight free radicals and can delay the signs of aging. These characteristics of milk thistle (along with a few others that we will discuss in a while) make it what it is – a simple herb bestowing us with its great benefits.

As per an Indian study, milk thistle has been used in traditional medicine to treat diseases of the liver and the biliary tract (1).

What Are The Health Benefits Of Milk Thistle?

1. Milk Thistle Boosts Liver Health

Milk thistle contains silymarin, an active ingredient that protects the liver. The ingredient is a group of flavonoids that repair the liver cells that are damaged by alcohol and other toxins. Silymarin also protects the new liver cells from getting destroyed. Throughout history, this herb has been used to treat liver diseases (2).

“Silymarin in milk thistle reduces liver injury in animals. Hence, it can possibly be a treatment option for alcoholic liver disease in humans.”
– Abenavoli L and Co., Department of Experimental and Clinical Medicine, University Magna Graecia, Catanzaro, Italy.

2. Protects The Kidneys And Gallbladder

As the kidneys work closely with the liver, and as milk thistle helps support liver health, it also promotes kidney functioning. The same goes for gallstones as well – studies have shown that this herb can help prevent gallstone formation. Milk thistle also protects the kidney cells, especially in the case of diabetic neuropathy (a condition in diabetes where kidney function is impaired) (3). It also supports the detoxification of the kidneys and gallbladder.

3. Aids Diabetes Treatment

Research suggests that when coupled with traditional treatment, milk thistle can improve diabetes. The herb can also improve insulin resistance and lower blood sugar levels. These effects of milk thistle can be attributed to silymarin (4).

Milk thistle also contains another compound called silibin, which was found to have positive effects on several diabetes complications (5). And another reason it could be good for diabetics is that it protects the liver – the liver also plays some role in releasing insulin into the bloodstream.

4. Milk Thistle Enhances Heart Health

Milk thistle may lower bad cholesterol and hence cut the risk of heart disease (6). It can also lower the cholesterol levels by lowering inflammation. It cleans the blood and prevents damage to the arteries due to oxidative stress. The herb also prevents glutathione depletion (we will discuss more of this in a bit), which is a master antioxidant that fights oxidative stress and prevents heart disease.

Other clinical studies have also proved that milk thistle has cardioprotective effects (7). A few other studies have shown how milk thistle can regulate blood pressure too.

5. Can Help In Cancer Treatment

The silybin in milk thistle can improve the functioning of certain chemotherapy drugs, especially in the case of ovarian cancer. The herb was also found to slow down the progression of prostate cancer cells. Some animal studies also found how milk thistle could reduce the side effects of chemotherapy (8).

Other studies state that milk thistle can induce cancer cell death in the case of colon and breast cancers. Though there is more research required in humans, this sure is an encouraging step (9).

6. Can Aid Weight Loss

There is some early research that shows how milk thistle can aid healthy weight loss. Mice fed with a high-fat diet lost weight after taking silymarin (10). And as milk thistle can regulate blood sugar, it may also help with weight loss – as research links steady blood sugar levels to improved weight loss.

7. Promotes Brain Health

Some early suggests that milk thistle can protect against multiple sclerosis and Parkinson’s disease. Silymarin was also found to suppress the formation of amyloid beta-protein, which is often linked to Alzheimer’s.

Several other studies also show how milk thistle can help prevent age-related brain ailments like Parkinson’s and Alzheimer’s. Some research also talks about the importance of milk thistle in treating anxiety and depression – but we need more information on this before we come to conclusions.

A study jointly conducted by research teams from India, Australia, and Iran states that silymarin can be a potential treatment for a variety of neurodegenerative disorders and forms of neuroinflammation (11).

8. Milk Thistle Strengthens Bones

Studies confirm that milk thistle can be used as a potential treatment for osteoporosis. The silymarin in milk thistle was found to be helpful in building bones and preventing bone loss (12).

Other studies talk about bone loss caused by estrogen, and how milk thistle might benefit in this aspect as well.

9. Delays Aging

The antioxidants in milk thistle fight free radical damage, and this eventually slows down the aging process. This is equally true with the signs of aging on the surface of your skin and within your internal organs.

Some research says that consuming milk thistle is one good way to reduce the signs of aging – which include wrinkles, dark spots, and fine lines (13). Internally, these antioxidants can delay aging by preventing joint pains and improving eye health.

10. Might Be Beneficial During Breastfeeding

Historically, milk thistle was used to increase the supply of breast milk. Some preliminary studies show that it can increase the levels of prolactin in the body, which eventually stimulates milk production.

However, we suggest you take your doctor’s advice before using the herb in this regard.

11. Boosts Immunity And Prevents Allergies

Studies have shown that milk thistle can have immunostimulatory effects. It can boost immunity and improve the body’s ability to ward off infections and diseases (14). And since milk thistle improves liver function, this also benefits the immune system – as the two are closely interlinked.

The antioxidants in milk thistle also boost immunity and counter allergies. Skin rashes are one of the allergies that milk thistle can counter. More importantly, the herb might fight acne as well. As acne is also caused due to bodily toxins, the detoxifying effect of milk thistle can have desirable effects on it.

12. Improves Digestive Health

Milk thistle boosts enzyme formation and the production of bile – and this contributes to digestive health. And given its anti-inflammatory properties, the herb also soothes the mucus membranes in the gut.

Studies also show how milk thistle has been used for centuries to treat upper gastrointestinal issues and other digestive ailments (15).

Those are the benefits of milk thistle. But there is another important aspect we need to know.

Milk Thistle And Glutathione (And Other Synergies)

We already discussed how milk thistle (silymarin) could protect against glutathione depletion. The herb, basically, preserves glutathione. This eventually strengthens the liver cell walls.

Glutathione is not the only compound milk thistle acts with in synergy. Other important ingredients like ashwagandha, curcumin, green tea extract, and gingko biloba extract powder also work in synergy with milk thistle and improve the antioxidant defense of the body.

There are other important compounds in milk thistle that are responsible for its wonderful benefits.

What Is The Nutritional Profile Of Milk Thistle?

Milk thistle contains a bio-flavanoid complex called silymarin. It is the primary ingredient of the plant. It is also the active compound that gives milk thistle its medicinal properties. Silymarin is made up of 3 flavanoids:

  • Silybin, which is also known as silibinin.
  • Silydianin, which is also known as silidianin.
  • Silychristin, also known as silicristin.

The main flavanoid in silymarin is silybin, which makes up about 50-70% of milk thistle’s most important extract. Silybin has been studied clinically, and researchers have found it to be the most beneficial and biologically-active component of silymarin.

Before extraction, milk thistle’s fruits contain:

  • Silymarin
  • Silyhermin
  • Neo-silyhermin A and B
  • Protein
  • Vitamin E
  • Sterols
  • Quercetin
  • Apigenin
  • Kaempferol
  • Eriodyctiol
  • Chrysoeriol
  • Naringin
  • Dihydroxychromone

The leaves contain:

  • Luteolin
  • Luteolin’s 7-0-Glucoside
  • Triterpene acetate
  • Fumaric acid

However, there are certain things about milk thistle that are not so good. Its overdose might lead to certain undesirable conditions.

What Are The Side Effects Of Milk Thistle?

  • Might Lower Blood Sugar Way Too Much

Since milk thistle helps lower blood sugar, it might lower the levels way too much in case someone is already on diabetes medications. Hence, consult your doctor before using it.

  • Allergies

Milk thistle can cause allergies in people who are sensitive to ragweed and other plants of the same family (Asteraceae).

  • Might Aggravate Hormone-Sensitive Conditions

Since milk thistle extracts might mimic estrogen, it might aggravate hormone-sensitive conditions like breast and uterine fibroids and uterine cancer. Hence, it is best to consult a doctor before using it.
