Milk Thistle is an annual or biennial plant growing up to 1.5 metres in height. Its conspicuous glossy green leaves are white-veined, sinuate-lobed with thorny teeth at the edges. Tufts of red-violet tubular flowers sit on the apically branching stalks in bent-back, thorny husk leaves. The hard-shelled, light to dark brown, egg-shaped fruits bear silken, white, tufts of hair that fall off easily. Milk Thistle flowers from June to September. Milk Thistle was formerly classified in the family of the Dipsacacaea, genus Carduus. The more recent botanic system puts it in the Compositae family.
The herb itself and its dried seeds, released from the pappus, are used medicinally. The fruits are harvested in August or September, just before becoming fully ripe. Once ripened, the seeds are threshed. A.Vogel/Bioforce produces a maceration from the whole fruits. This method ensures that the silymarin contained in the shell of the fruit, is extracted without losing the fruit's fatty oil. Tea preparations from the whole fruits, which must infuse for at least 10 minutes, are rarely used. In France, the young leaves, unopened flower heads, and tap root are a very popular delicacy.
