Safety Overview
1.Queen's Delight — At a Glance
Stillingia sylvatica, commonly known as Queen's Delight or Queen's Root, is a remarkable perennial herb. It belongs to the diverse Euphorbiaceae family, which also includes the castor bean. The plant is native to the southeastern United States. It thrives in the region's sandy, well-drained soils. You will often find it in pine barrens and open woodlands. Its robust nature lets it develop a deep, woody taproot.
This taproot is the main part used in traditional and modern herbalism. The plant typically grows to about 2-3 feet in height. It bears alternate, sessile leaves that are usually smooth and entire. Its inflorescence consists of terminal spikes of small, greenish-yellow flowers. These flowers mature into small, three-lobed capsules that contain seeds. A characteristic milky latex marks Stillingia's botanical profile, a common feature of many Euphorbiaceae members.
The plant exudes this latex when injured. The latex holds concentrated acrid and resinous compounds, and these contribute greatly to its medicinal properties. Historically, indigenous Native American tribes recognized and used Stillingia for its powerful alterative properties, especially in the southeastern regions. They did so long before European and early American herbal traditions adopted it.
