Milk Thistle for a Healthy Liver and More

Milk Thistle Liver Health Benefits

Milk thistle is an ancient plant that dates back to the first century and has been used to treat a variety of ailments, particularly those affecting the liver, kidney, and galbladder. It’s native to the Mediterranean region but can now be found growing throughout many parts of Canada, the US, and the world.

Milk thistle gets its name from the white sap that is produced when its wide leaves are crushed. The flowers are a reddish-purple, and the fruit (commonly referred to as the seed) is hard, brown, and shiny. The active ingredient, which is extracted from the seeds, is silymarin – a group of flavonoids with anti-inflammatory and antioxidant properties.

Although milk thistle as a healing plant became less common during the 20th century, it seems to be making a comeback as more people are looking for natural remedies for their ailments and health issues. The most common use of milk thistle is to promote liver health, but there are some other less known health benefits from this healing plant.

Health Benefits of Milk Thistle

Liver Health – During the 1980s, researchers found that silymarin helps liver cells regenerate through a bodily process known as protein synthesis. Silymarin has also been found to help repair liver cells damaged by toxic substances such as alcohol or poisons. It also keeps new liver cells from being destroyed by these same toxins, as well as preventing liver damage if taken before toxin exposure.

Cancer – Silymarin not only stops cancer cells from dividing and reproducing, it also shortens the life span of the cells and reduces the blood supply sent to the tumors. Silibinin (a flavonoid in milk thistle) has been specifically shown to inhibit prostate cancer cell growth and induce cell death in human colon cancer cells.

Hepatitis C – Silibinin has been shown to have antiviral effects and improve liver function in patients with Hepatitis C. This study concluded that orally-administered silibinin is a potent anti-viral agent in patients with chronic Hepatitis C who are otherwise no longer responding to traditional forms of therapy. Silymarin has also been found to improve symptoms of acute clinical hepatitis.

Osteoarthritis – Silymarin’s anti-inflammatory properties make it a great contender to replace conventional medications for osteoarthritis of the knee, as shown in this study. When compared with 2 major osteoarthritis drugs, silymarin significantly reduced serum levels and complement proteins when used alone.

In general, anyone with a liver-based health issue including cirrhosis, jaundice, hepatitis, damage from alcohol or drug abuse, or liver poisoning from other foreign chemicals can benefit from the healing effects of the milk thistle plant.

How to Take Milk Thistle

Milk thistle comes in a variety of forms, including capsules of dried herbs, liquid extracts, and tinctures. From Mother Earth Living:

For preventive care, take 420 mg of silymarin divided into three doses for six to eight weeks, after which the dose can be reduced to 280 mg per day for an indefinite period. Look for preparations that are standardized to 80 percent silymarin.

If you have a liver condition and are considering adding milk thistle to your health care regimen, please consult your doctor, as liver disease can be life threatening and should be managed under the care of a health care professional.

There are no studies showing whether it’s safe to give milk thistle to a child, so it’s best to speak with your child’s doctor before giving this or any herb to your child.

    • Hmm, I’ve never heard of that. In fact, milk thistle has traditionally been used as an emergency antidote to mushroom poisoning! I think what you may be referring to is milk weed, which is a different plant entirely, and can be toxic to humans if consumed in large quantities.

      Hope that helps!

  2. I take several medications for various ailments, many of which affect my liver. Where can I go to determine if Milk Thistle will react with any of my meds? My doctor knows nothing about herbals.

    • I think that’s something you’d have to speak to a medical professional about. If your doctor can’t help, you can try looking for a naturopath who should be able to help or at least point you in the right direction. Good luck!

    • Hi Meghan, although milk thistle is commonly found growing in gardens across the world, the actual cultivation, harvesting, and preparation into tinctures, capsules, etc is a whole other issue entirely and would require at least a few more articles to explain the process. That’s why we opt instead to share where it can be sourced at your local health food store.

      However, in light of your comment, I’ll go ahead and try to locate some helpful sources for those who may be interested in preparing it themselves at home, and I’ll add that info to this post. 🙂
