What is Blessed Thistle?

Blessed Thistle is a small annual thistle native to Mediterranean and Western Asian regions. The plant was cultivated extensively in medieval European monastery gardens and gained a reputation as a near-panacea, with documentation in herbals from the 14th century onward.

How to Use Blessed Thistle

For tea: steep 1 teaspoon of dried herb per 8 oz cup in hot water for 10 minutes, then strain. Blessed Thistle is extremely bitter; sweetening or blending with milder herbs is common. Also widely used in tincture form for measured dosing.
