Which milk thistle tea is best?

Although it may look like a common weed to the untrained eye, the milk thistle plant has been used in traditional medicine for thousands of years. Studies have shown that this flowering plant can be used to promote healthy liver function, so many people have begun ingesting milk thistle in the form of herbal tea.

You can buy the seeds of the milk thistle in bulk or blended with other herbs in conventional tea bags. The Starwest Botanicals Organic Milk Thistle Seeds are the top pick because they’re certified kosher and organic by reputable third-party organizations.

What to know before you buy milk thistle tea


The purported health benefits of milk thistle tea are thought to come from a chemical compound called silymarin. As with other herbal teas, steeping the plant material in hot water is a great way to receive the potential benefits of silymarin without ingesting the whole seeds.


  • Milk thistle is primarily used to protect the liver from damage caused by hepatitis, alcoholic liver disease and even liver cancer. Studies have shown that the plant might fight off free radicals that could harm the liver, making it a useful addition to conventional medical treatments.
  • The plant has anti-inflammatory properties and is loaded with antioxidants, which means it also has potential as a treatment for certain ailments related to mental decline.

Side effects

Milk thistle tea is considered safe to consume, even on a regular basis, but there are a few side effects to think about before introducing it into your daily routine. A small percentage of people could experience an upset stomach or nausea, and those with a sensitivity to milk thistle or any other plants in the daisy family should avoid drinking the tea. Milk thistle could lower your blood sugar levels, so people with diabetes should talk with their doctor before ingesting the plant. Lastly, there haven’t been very many human-based studies done on the plant, so people shouldn’t drink milk thistle tea as a replacement for any conventional medical treatments.

What to look for in a quality milk thistle tea


Most people buy milk thistle in the form of tea bags or seeds by weight, but you can find the plant in capsules or a concentrated liquid extract. Making tea from the seeds is perhaps the most natural way to consume the beverage, but the process typically requires crushing the plant material with a blender or mortar and pestle.


For a high-quality tea, look for milk thistle that has been certified organic by a third-party organization or the United States Department of Agriculture. You can also find products that are certified kosher, vegan and free of genetically modified organisms.

How much you can expect to spend on milk thistle tea

While exact costs can vary, if you’re buying milk thistle in bulk, expect to spend around $10-$20 per pound of seeds. A box of tea bags is usually cheaper at around $0.50 per bag.
