Milk thistle (Silybum marianum) is a member of the Asteraceae family, which also includes plants like daises and thistles.
Silybum marianum is likely native to southern Europe but is now commonly found throughout the continent. European settlers brought milk thistle to North America and it is now dispersed through North and South America.
The plant can reach 5 feet in height and grows large, purple flowers, which are sometimes eaten like artichokes. It has spiky leaves with white veins, which is likely where it received its common name, milk thistle.
It was historically referred to as Mary thistle because historical European literature said the white in the leaves was the milk of the Virgin Mary. The first recorded use of milk thistle dates back to Ancient Greece when it was administered to patients who had been bitten by poisonous snakes.
Since then, it has been used by physicians and herbalists to treat disorders of the gallbladder and liver. Contemporary scientific investigation has focused on the use of milk thistle to treat liver disease, including fatty liver disease, alcoholic and non-alcoholic cirrhosis and toxic hepatitis.
Most investigation focuses on an extract of the milk thistle plant known as silymarin, which is thought to be the active constituent. Scientific reviews of Milk Thistle Extract typically attribute the majority of beneficial properties from this plant to the silymarin concentration.
Health Benefits of Silymarin and Milk Thistle
Silymarin is comprised of a group of flavonolignans and flavonoids, including silydianin, silychristin, silibinin and sylibin. Because of its therapeutic importance in the plant, the names silymarin and milk thistle are often used interchangeably, especially in the supplement marketplace.
Silymarin has been observed to have antioxidant, anti-inflammatory, anti-lipid-peroxidative and immunomodulating effects, which is what researchers suspect helps aid in the treatment of some liver disorders.
Milk thistle is also taken orally for dyspepsia, diabetes, hangover, diseases of the spleen and to help relieve the symptoms of allergic rhinitis. It is also sometimes used to treat skin conditions such as acne and psoriasis and to help relieve pain in arthritis and rheumatism.
It is also used to mitigate symptoms of menopause, such as hot flashes and night sweats. Milk thistle may be a key ingredient in some detox and liver cleanse formulas.
This herbal extract can be found in many forms and supplemental combinations on the market. These formulas may be marketed for a variety of therapeutic purposes. Milk thistle reviews can be helpful in determining what combinations have worked and for what condition.
Milk Thistle Supplements
The most common form of milk thistle supplements is an oral capsule that contains a powdered extract from the plant. Capsules will typically be denoted with a standardized concentration of silymarin extract in the form of a percentage (i.e. 80% silymarin) or in the form of a ratio (i.e. 30:1 extract). Capsules will typically contain between 100 – 500 mg of Milk Thistle (Silybum marianum extract).
Due to the differences in how the extract concentrations are calculated, it is recommended to follow dosage guidelines as directed by the manufacturer. Milk thistle reviews generally recommend taking one capsule three times a day with meals to prevent stomach discomfort.
