The Medicinal Herb Info site was created to help educate visitors about the often forgotten wisdom of the old ways of treating illnesses. Many of today's drugs and medicines were originally derived from natural ingredients, combinations of plants and other items found in nature.

We are not suggesting that you ignore the help of trained medical professionals, simply that you have additional options available for treating illnesses. Often the most effective treatment involves a responsible blend of both modern and traditional treatments.

We wish you peace and health!

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.
