What is it

Joe-Pye weed (Eutrochium purpureum, also Eupatorium purpureum), called gravel root or queen of the meadow, is a tall North American perennial. It was traditionally used by Indigenous and early American settlers for kidney and urinary support.

How it works

Eutrochium purpureum contains volatile oils, flavonoids, and trace amounts of pyrrolizidine alkaloids. Traditional use focused on diuretic and urinary-stone effects. Modern pharmacological mechanisms are not well characterized in peer-reviewed literature. The presence of pyrrolizidine alkaloids is a modern safety concern, since some pyrrolizidine alkaloids are hepatotoxic. Levels in Eutrochium are generally low but variable.

Dosage

Traditional decoction doses use 5 to 15 g of dried root per day. Short-term use only, given safety considerations.

When and how to take it

Traditional use is typically between meals, short-term only. Drink ample water with use.

Frequently asked questions

Is gravel root safe?⌄

Pyrrolizidine alkaloid content is a concern for chronic use. Short-term use of tested products may be acceptable, but long-term use is discouraged.
