Silybum marianum (L.) Gaertn. Asteraceae Milk thistle. Carduus Mariae. Distribution: Europe. Gerard (1633) calls it Carduus Mariae, Carduus Lectus, or Ladies Thistle, and Carduus leucographus [meaning 'white writing', in reference to the white markings on the leaves] because Pliny wrote about a plant he called Leucographis although Gerard notes that it would be 'hard to assume this to be the same [plant].' He also queries if it is the same as the Alba spina of Galen. Of the latter he reports that Galen recommended it for all manner of bleeding, toothache and the seeds for cramp. Gerard writes that Dioscorides recommends that a drink of the seeds helps infants whose sinews are 'drawne together'
