Scotch Thistle
Onopordum acanthium
Long before it became a stubborn roadside weed to modern eyes, cotton thistle held a real place in the European herbal cabinet. Old herbalists like Culpeper wrote of the root and leaf being boiled or bruised into applications for sores and skin complaints, and country folk drank the bitter leaf as a tonic to wake up a tired appetite before meals. Its silvery, cobweb-soft leaves and towering purple crowns also made it a familiar sight in cottage gardens grown simply for their dramatic, architectural beauty. Most famously, this thistle (or one very like it) is the plant behind Scotland's national emblem, carried into legend as a humble weed that once saved a sleeping clan.

Traditional preparations.
Traditionally taken as a mild bitter tonic before meals to encourage a sluggish appetite and ease heavy digestion.
Steep 1 teaspoon of the dried leaf in 250 ml of just-boiled water for 8 to 10 minutes, then strain. Traditionally sipped in small cups shortly before eating.
An old folk preparation, simmered and cooled, traditionally dabbed on minor skin irritations.
Simmer 1 tablespoon of chopped dried root in 500 ml of water for 15 minutes, then cool completely and strain before applying to the skin with a clean cloth.
Safety.
This plant is covered in sharp spines, so handle it with gloves. As a daisy-family plant it may cause a reaction in people sensitive to ragweed or chrysanthemums.
