"I consider standardized Milk Thistle seed extract the most beneficial herbal product for liver detoxification, regeneration and protection, and, in general, one of the most universally necessary herbal products for the 1990s," says Schechter. He notes that the stress of toxins from chemical pollutants, pharmaceuticals, alcohol, tobacco smoke, drugs and different forms of radiation have cumulative side effects that need to be addressed.
More than 120 scientific studies have shown that it regenerates, regulates and strengthens liver functions. Because free radicals attack the liver, primarily the fat tissue in the liver, its antioxidant qualities are extremely beneficial. Milk thistle stimulates your body to produce superoxide dismutase, which is one of two primary antioxidants the body can manufacture. Antioxidants are the free radical fighters in your body.

It does have some side effects though and that's why some people ask if it is safe. Let's say you decide you want to use it for a liver cleanse. And let's also say that you've eaten a lot of fatty food and drunk a lot of alcohol in your life. If you're even just in your 40s, your liver is probably pretty toxic. Actually, even if you've kept a pretty clean diet, your liver can still be fairly toxic. After all, it is the organ in the body which filters out any impurities you take in. And in our imperfect world filled with many, many sources of toxicity, it can have a lot of filtering to do.
Now let's also say that you just jump into this liver cleanse without asking the advice of a competent herbalist. You take 3 or 4 capsules one night before you go to bed. The next morning, you wake up with a huge headache and are so nauseous you can hardly get out of bed.
Yep. You're having a cleansing reaction. This herb is a very powerful cleanser and wants to be approached carefully. The reaction you're having won't hurt you in the long run but in the short run it can make you feel awfully bad. So if you do something like this, just back off and start over again, slowly.
And, of course, if your physician has diagnosed you with any kind of liver dysfunction, you'll want to check with her before you do anything like this.
But for reasonably healthy people who want to stay that way, the use of milk thistle for a liver cleanse is a valuable tool to add to your box of preventive health remedies.
