Milk Thistle Seed Important For Hormonal Balance

Milk Thistle Seed Important For Hormonal Balance

Milk Thistle (Silybum marianum) supports hormonal balance. It is one of the best plants for liver health. Liver health is vital for hormonal balance. The liver helps to filter toxins from the body, including excess hormones. It is also commonly called Blessed Thistle, Marian Thistle, Holy Thistle. The name Milk Thistle comes from its milky sap. Traditionally it is associated with increasing breast milk production, which may be another reason for it’s name.

Liver Cleansing and Renewal
The plant part used is the seed. Milk Thistle Seed Extract is part of our Fertility Cleanse Kits for both women and men. It is part of these kits because Milk Thistle Seed’s stimulate the liver to cleanse itself, while also stimulating it to renew liver cells. Milk Thistle seeds also stimulate the liver and gallbladder to secrete bile, aiding in digestion. Milk Thistle is the most protective plant for liver health! In fact it is so protective of liver health, it is used to save people from Death Cap mushroom poisoning. It is also used to heal and protect the liver’s of people who have undergone chemotherapy.

The liver is our chemical processing plant. So you can imagine what must go on in there. The liver removes hormones, drugs, and other biologically active molecules from the blood. It then converts these by changing their structure or inactivating them, through different processes, and then excretes these to be passed through the kidneys. If there are too many excess toxins and hormones overwhelming the liver, they may be stored up, not only in the liver, but other parts of our body. Milk Thistle gives our liver the support and renewal it needs to function at its best!

Silymarin in Milk Thistle Protects the Liver
Silymarin is the main constituent in Milk Thistle that protects liver health. This is only one constituent (part, or chemical compound) found in Milk Thistle. Some people believe that your Milk Thistle product should have at least 420mg of Sylmarin to be effective. Unless your product has gone through a processing plant, that has scientific researchers testing each batch for chemical constituents in the plant, and then reporting that to the company to put on a label, there is no way to determine how much Silymarin is in each tablet. As an herbalist my personal opinion on this, is that Milk Thistle seeds are best taken in a tincture form (liquid extract), like the one we sell in our Natural Fertility Shop. Milk Thistle seeds are very hard, and hard to digest in capsule or tablet form. Grain Alcohol is the best way to extract the medicinal properties, including Silymarin in Milk Thistle.

There have been some studies on Silymarin in Milk Thistle. These were performed to see why Milk Thistle was helpful to the liver, they found that Silymarin was the main part of the plant that aids the liver in cleansing and regeneration. This popularized Silymarin and many products are now sold with this name, rather than by Milk Thistle. Personally, I feel that using a whole plant part ensures you are receiving the wide variety of medicinal benefits from the plant, rather than isolating one part of it.

Why Milk Thistle Seed Should Be a Part of Your Natural Fertility Plan

  • Stimulates liver regeneration and cleansing.
  • Flushes excess hormones from the liver.
  • Flushes toxins from the liver.
  • Heals the liver from toxin damage from alcohol, car exhaust, chemical pollution, ect.
  • A clean liver aids in hormonal balance.
  • Protects the liver from future toxin damage.
  • Some research shows it is helpful for people with insulin resistance, including PCOS and type 2 diabetes.

Milk Thistle Increases Breast Milk Production
Fast forward, you are now pregnant and looking forward to meeting your baby. Are you planning to breastfeed? If so (highly recommended), consider having some Milk Thistle Seed Extract on hand, to help support ample amounts of healthy breast milk for your baby! Milk Thistle has also been found to chase depression away. This makes it very helpful in preventing the baby blues, or postpartum depression.

General Suggested Dosage (for both women and men): 30 drops, 2-3 times a day in a little water.

Milk Thistle has been shown safe for use long-term. It can be made into a tea, but I find it works best as a liquid extract. To see Milk Thistle Extract click here…

*NOT recommended for pregnancy. If you are allergic to any plants in the Asteracea family (daisy) family, avoid this plant.

Additional Thoughts on Milk Thistle
Milk Thistle Seed Extract is one herb I like to have in my home at all times. We are constantly bombarded with toxins daily, our liver takes on a lot of stress. Milk Thistle Extract helps me to know that I am protecting my liver, which allows me to not have to worry as much about the damage being done to it.

If you love to grow plants like I do, you may be interested in growing your own Milk Thistle. Watch out though, this plant is a real pricker. Compared to the normal roadside thistles around, Milk Thistle’s spines are much stronger, longer and hurt a lot more to be pricked by. Wear thick gardening gloves when handling this plant. It is a beautiful thistle, with a bright purple flower, variegated white and green leaves and spines at the tip of the leaves and below the flower head. Young leaves are also nourishing and protective to the liver. The young flowering tops have a heart that can be eaten. It is said to taste much like an artichoke heart, though I cannot attest to this. At the end of summer as the plants seed are ready, be even more cautious of the spines. As the plant tops begin to dry and die off for the year, the spines become even harder and thinner. If you don’t handle it properly (I know) it feels like a thousand needles are stabbing into you. Literally, it is probably close to this, okay maybe more like hundreds, but still, it hurts!

  1. Hi,
    Thank you for sharing so interesting and useful information. Your site is like a natural fertility manual and I enter it on a daily basis. I’m 39 and I’m currently trying to conceive. A year ago I was diagnosed with a small fibroid ~13mm and I have some hormone imbalance(high estrogen levels). I take DIM each day and I place castor oil packs before ovulation, but additionally I would like to do some liver cleansing and to start taking Vitex. Is it ok for me to take both herbs having in mind that I’m trying to conceive and I would like to get pregnant asap? Shall I start first with Milk Thistle, or I can take both herbs at the same time?

    • Dear Katrin,

      Thank you for your praise!

      Fertilica Milk Thistle See Extract and Fertilica Vitex can be combined with DIM and Castor Oil Therapy all of which can be used while trying to conceive. Fertilica Milk Thistle and DIM are to be discontinued upon first determination of pregnancy. Fertilica Vitex can be weaned off of in the early pregnancy and Castor Oil Therapy is only to be done from after menstruation ends until ovulation during cycles when actively trying to conceive.

  2. I started taking milk thistle a couple weeks ago. I take birth control to regulate my periods. This week, I haven’t gotten my period. Can milk thistle stop women from menstruating? Thank you!

    • Dear Dominique,

      I have not heard of Milk Thistle Seed Extract delaying menstruation. This being said, in stimulating the liver to detoxify and cleanse, which is what Milk Thistle Seed does, there can be shifts in the menstrual cycle. We find any shifts temporary, to work themselves out and a sign the body is responding to the herb’s actions.

      I understand you are on birth control, but it is not 100% effective in preventing pregnancy. Is there a possibility you could be pregnant?

      It may be worth speaking with your healthcare provider about taking Milk Thistle Seed Extract with your birth control as well.

      I hope this is helpful!

  3. Hi
    I read this on “Since milk thistle may mimic the effects of estrogen, some women should avoid this herb. This includes women who have fibroid tumors or endometriosis. Additionally, women with breast, uterine, and ovarian cancers should not take milk thistle.”
    Is this true? I have included the link above.
    I would be grateful if you could let me know as
    I’m taking this regularly and I have endometriosis.

    • Elizabeth Willett, MA, CH

      Dear Rea,
      We don’t believe this to be true in most cases and if using the general suggested dose of (for both women and men) 30 drops of Milk Thistle Liquid Extract, 2-3 times a day in a little water. If you have great concern or are undergoing medical treatment for any condition mentioned, you should speak with your healthcare provider about using any herb.

      What I should share is that in order to promote healthy estrogen balance within our bodies, we have to consider how herbal phytoestrogens protect us from harmful xenoestrogens (toxins), which come from human-made chemicals (herbicides, pesticides and fertilizers to name a few) and are found in conventional foods, personal and body care products, paper products… a great many of the things many use in their daily lives. Xenoestrogens may cause estrogen dominance. Because of this we must consider liver supporting herbs for natural detoxification. The liver helps to filter toxins from the body, including excess hormones, and when the body has detoxified from toxins, our good, beneficial hormones are able to connect with hormone receptor sites and benefit various body systems.

      Because Milk Thistle is known as one of the most supportive herbs of liver health and healthy liver function is vital for hormone balance, we feel it valuable for many or our clients.

      Take Care!
