What is Milk Thistle?

Milk thistle (Silybum marianum) is a tall, purple flowering plant with prickly spines. Originally from the Mediterranean region, milk thistle has a long history of use in medicine and healing. For thousands of years, milk thistle has treated health problems of the liver and gallbladder. It's also a well-known galactagogue that nursing women use to help increase their supply of breast milk.

Milk Thistle and Breastfeeding

Milk thistle has been linked to breastfeeding for a very long time. Also known as Saint Mary's Thistle and Our Lady's thistle, this herb is a plant of legend. Stories from long ago suggest that the leaves of the milk thistle plant have white veins running through them because milk from the breast of Mary, The Virgin Mother splashed onto the plant. To some, these white veins symbolize breast milk, and it's believed that when a breastfeeding mother uses this herb, it will lead to an increase in her breast milk supply.

Beyond the legends, milk thistle has been used with positive results by nursing women in India and Europe for generations. And, although there is no true scientific evidence that milk thistle can help a nursing mother to make more breast milk, it has been shown to increase the milk production in dairy cows. It is also believed that the plant estrogens found in milk thistle could be a reason some women report making more breast milk when they take this herb.

 

How to Use Milk Thistle to Make More Breast Milk

Milk Thistle Tea: You can make a tea from the seeds of the milk thistle plant and drink it two to three times a day. Just place one teaspoon of crushed, ground, or chopped milk thistle seeds into 8 ounces (240 ml) of boiling water. Let it sit or steep for 10 to 20 minutes, and then enjoy.

 

Milk Thistle Supplements: Milk Thistle capsules, soft gels, powder, and a liquid extract is available online and in health food or vitamin stores. If you choose to use an herbal supplement, be sure to buy it from a reputable source and follow all the directions for that particular herbal product. You should also talk to your doctor or a lactation consultant for the correct dosing information.

Milk Thistle as Food: Once you remove the spines, you can eat every part of the milk thistle plant. The seeds can be roasted or used to make tea, the leaves can be eaten raw or cooked, and the buds can be enjoyed similar to tiny artichokes.

Breastfeeding Teas and Supplements: Milk thistle is a common ingredient found in some of the already prepared nursing teas or lactation supplements that are commercially available. It is often used in combination with other breastfeeding herbs such as fenugreek, fennel, goat's rue, marshmallow root, and verbena.

Warnings and Side Effects of Milk Thistle

  • Always consult your doctor, a lactation consultant, or an herbal specialist before taking any herbs especially if you're pregnant or breastfeeding. Many herbs are just like medicine, and they can be harmful if you do not take them as directed. Herbs can also interfere with other medications that you may be taking.
     
  • Milk thistle should not be confused with blessed thistle; it is an entirely different plant.
     
  • Allergic reactions to milk thistle are rare. However, if you suffer from allergies to ragweed, daisies, marigolds, or chrysanthemums should not use milk thistle since it is a member of the same plant family.
     
  • Milk thistle is generally considered to be a safe herb. The most common side effects are mild and stomach related. When it's taken in excessive amounts, loose bowel movements, stomach upset, nausea and vomiting are possible. 
     
  • Milk thistle has been used to cleanse the liver and detoxify the body. During the process of cleansing, toxins from inside your body are released into your bloodstream so that they can be removed. When these toxins are in your blood, they can enter your breast milk and pass on to your baby. If you have toxins stored in your liver from heavy smoking, alcohol, or the use of drugs, you should not use milk thistle while you're breastfeeding.
     
  • Do not take milk thistle if you use the seizure medication Dilantin (phenytoin).
     
  • Milk thistle can interfere with birth control pills making them less effective. It can also cause problems if you're taking antipsychotic drugs, antianxiety drugs, certain cancer medications, or blood thinners. Make sure you talk to your doctor about any medications that you're taking before you use milk thistle.
