This is another plant listed for reproductive issues in my herbal studies, but when I researched, only A Modern Herbal mentioned it as one of the best herb for lactation. And The Way of Herbs says since abnormal periods are usually accompanied by liver issues, so it is typically added to reproductive formulas. Seems like one of the major use for this herb outside of lactation is as an appetite stimulant.
Also, other thistles, particularly milk thistle, have similar actions.
PS The actions listed are all the ones mentioned across my sources. There are a lot of them!
