It is usually taken in capsules or as a tea. It is said to work by stimulating the flow of blood to the mammary glands, and thereby enriching the milk flow.
Blessed thistle was historically reputed to be a heal-all, and was even said to heal the plague. It is recommended for birthing and nursing mothers because of its hemostatic properties, which reduce the likelihood of postpartum hemorrhage, and because of its antidepressant effects." from lowmilksupply.com
