Silymarin is a unique flavonoid complex—containing silybin, silydianin, and silychrisin—that is derived from the milk thistle plant. These unique phytochemicals from the milk thistle have been the subject of decades of research into their beneficial properties.
Milk thistle is a common name for Silybum marianum, a flowering plant in the Asteraceae family. It also has many other common names, including Marian thistle, Mary thistle, Saint Mary's thistle and Scotch thistle. Milk thistle originates from Southern Europe, although it is now found in temperate regions throughout the world.
Milk thistle typically grows as a shrub with a conical shape, exceeding six feet in height and five feet in diameter under ideal conditions. The stems are grooved and become hollow as the plant matures. The leaves are shiny green with milky-white veins, which is how milk thistle gets its name. The flowers are reddish-purple and bloom during the summer.
