Medicinal Uses

Blessed thistle is used in folk remedies as a galactagogue with other herbs to increase breast milk supply, although there is no scientific evidence that such use is effective. Although the leaves are unpalatable with a bitter taste, blessed thistle is used as a flavoring in alcoholic beverages, and is considered a safe ingredient for food uses. As a member of the ragweed family, blessed thistle may cause allergic reactions in susceptible people, and use of large amounts may cause stomach cramps, nausea and vomiting.
