🌿 Milk Thistle – The Guardian of the Liver

Milk Thistle – A Spiny Plant with a Long-Trusted Seed
Latin Name: Silybum marianum
Also Known As: Holy Thistle, Mary Thistle, St. Mary’s Thistle

🌱 Botanical Source

Milk Thistle is a biennial plant native to the Mediterranean but now naturalized throughout Europe, North America, and Australia. With its striking spiny leaves, upright growth, and brilliant purple flower heads, it’s both eye-catching and hardy.

The seeds—technically the plant’s fruits called achenes—are the prized part, harvested once the flowers dry out. These contain the active complex silymarin, and are commonly sold whole or milled.

At Foothills Naturals, we offer whole milk thistle seeds and a fine powder for those who prefer ease of blending or brewing.

📖 History & Traditional Uses

Milk Thistle has been used in herbal traditions for over 2,000 years, dating back to ancient Greece and Rome.

• In classical Europe, it was valued for supporting digestion and liver function.

• The Doctrine of Signatures, a medieval concept, suggested that the white veining on its leaves symbolized its use in protecting and nourishing internal systems.

• German Commission E officially recognized milk thistle for liver and gallbladder support in herbal monographs.
