Milk thistle, with its distinctive purple flowers and long, thorny leaves, has long been touted for its liver health benefits and detoxing prowess.
Milk thistle and its healing properties were first described by the Greek physician Dioscorides in 40 A.D. Dioscorides was a physician, pharmacologist, botanist, and the author of De Materia Medica, a five-volume Greek encyclopedia describing herbal medicines that was the leading pharmacological text for 16 centuries. He was employed as a physician and surgeon in the armies of Roman emperor Nero, which gave him the opportunity to travel extensively, studying the features, distribution, and medicinal properties of many plants and minerals.
Also known as silybum marianum, milk thistle is native to the Mediterranean region and is part of the daisy, or Asteraceae family. Milk thistle is found in the Eastern United States and California, South America, Africa, Australia, and Asia.
Milk thistle plants are able to grow up to 10 feet, with broad leaves with distinctive milky white veins. Some cultures believe the veins originated from a falling drop of the milk of the Virgin Mary, which is why it’s sometimes referred to as Our Lady’s thistle, blessed milk thistle, St. Mary’s Thistle, Holy thistle, Virgin thistle, and Christ’s crown.
Milk Thistle’s Medicinal Properties
For more than 2,000 years, milk thistle has been used as a liver tonic and to treat other liver diseases, such as jaundice, cirrhosis, hepatitis, and poisoning, as well as to cleanse the liver from alcohol and drug addiction. Milk thistle also stimulates the appetite, treats psoriasis, and is used by nursing mothers to increase milk production and lactation.Liver Health and Detox
“Silybum marianum or milk thistle (MT) is the most well-researched plant in the treatment of liver disease,” reads a research review published in Phytotherapy Research in 2010.Milk thistle cleanses the liver of toxins, is used for overeating or overindulging in recreational drugs or alcohol, treats jaundice and cirrhosis, and has a protective effect on the liver, helping it to regenerate healthy liver cells after damage.
“Silymarin has been used to treat alcoholic liver disease, acute and chronic viral hepatitis, and toxin-induced liver diseases,” the review reads.
An Antidote to Poisoning
Milk thistle has been used to counteract many poisons for as long as 2,000 years, when early physicians used it to treat snake bites and other poisonings. In modern times, milk thistle has been used successfully against poisoning from death-cap mushrooms, an increasing problem in the United States since their accidental introduction from Europe.Cancer Protection
Milk thistle is also showing promise in the fight against cancer. A study in the World Journal of Gastroenterology shows that the primary bioactive compound found in milk thistle, silibinin, could suppress the growth of cancerous liver cells. The study shows that silibinin significantly reduced the development of several human hepatoma cell lines. They were also able to demonstrate that silibinin mediates anti-cancer liver effects by:- reducing cancer cell proliferation and cell cycle progression.
- enhancing programmed death of cancer cells.
- altering the chromatin structure of the cancer cells.
Boosts Milk Production for Breastfeeding Mothers
As a galactagogue (lactation inducer), milk thistle has long been known to help nursing mothers produce more milk for their babies. Galactagogues increase the flow of mother’s milk. A study shows that women treated orally with milk thistle’s famed bioflavonoid complex—silymarin—saw an 85.94 percent increase in daily milk production. No negative effects were reported, and it was very well tolerated by all the participants.Helps Diabetes
According to the Centers for Disease Control and Prevention (CDC), approximately 37 million people in the United States have diabetes, which is more than 11 percent of the population. Thankfully, milk thistle has been shown to stabilize blood sugar levels and help with Type 2 diabetes, and it may offer a more natural solution for those struggling with the disease.Milk Thistle in Chinese Medicine
In Chinese medicine, milk thistle is known as the herb da ji or shui fei ji (milk thistle seeds). Milk thistle works specifically on the liver, heart, and spleen and is considered bitter, cooling, and drying. Its actions are to remove stagnation (blockages), stop bleeding, stimulate qi (energy), benefit the skin, heal wounds, reduce swelling, promote urination, and strengthen the liver.Risks and Side Effects
Milk thistle is generally considered very safe to use and has very few cases of reported side effects. That said, always use caution if you have any health conditions, are on medications, or have seasonal allergies, especially to any plants in the daisy or Asteraceae family. If you would like to begin taking milk thistle—or any other supplement—always start with smaller doses to see how you tolerate it, then increase the dosage slowly, paying close attention to any reactions. If any occur, discontinue use and consult with a health care practitioner.Possible Drug Interactions
Certain medications have been known to interact with milk thistle, including allergy medications, blood thinners, and anti-anxiety drugs. Silymarin has also been shown to lower blood sugar. Although it has been proven helpful for diabetic patients, always consult your physician before taking milk thistle if you have diabetes or are on diabetes medications. As a general rule, you should consult with a health care practitioner before taking supplements if you’re on any medication.Final Thoughts
In recent years, the popularity of milk thistle has increased, perhaps because of the public’s desire for more natural approaches to chronic diseases and the popularity of liver detoxing. In fact, a report has projected that the 10-year forecast for milk thistle supplements is estimated to be worth $204 million by 2032.With milk thistle’s massive list of medicinal benefits and the public’s growing mistrust of Western drugs and treatments, it seems prudent to look to nature—where a large percentage of pharmaceutical drugs originate—to fulfill as many of our health needs as possible. Milk thistle is easily grown in most locations with ample sunlight, and harvesting its seeds can help with many health problems we now face in the modern world.
