Legends, Myths and Stories

Blessed thistle has been used medicinally for centuries. Once considered a rank weed and an obscure food plant (young leaves with spines removed are edible), in recent years this thistle has gained prominence as a medicinal plant, especially in Europe. Clinical trials have found it useful in the treatment of Amanita mushroom poisoning; it is credited with saving a number of lives in Europe.

For menstrual problems, it is taken in combination with other herbs such as ginger, cramp bark, and blue cohosh root. This herb is often included in commercial herbal preparations designed specifically for women. Blessed thistle is sometimes cultivated, but mostly it has escaped from garden areas.

Uses

Folk tradition historically regarded this plant as a remedy for amenorrhea and suppressed menstruation. Herbalists administered it with the belief that it stimulated appetite, stomach secretions, memory, and bile production, while also supporting milk flow in nursing mothers. Traditional practitioners utilized the herb in efforts to address poor circulation, blood clots, pneumonitis, heart weakness, and dropsy, as well as to purify the blood.

Brewed as a tea, it was traditionally employed for digestive complaints such as intestinal gas, constipation, and liver disorders, including jaundice. Historical records also document its use for colds, fevers, headaches, migraines, gout, boils, chilblains, deafness, and ringworm.

Warning

Handle carefully to avoid toxic skin effects. Large doses may cause irritation, vomiting. Should not be taken during pregnancy; it stimulates onset of menses.
