Stillingia sylvatica, or Queen's Root, grows in the southeastern United States. Native American and Eclectic medicine traditions used the root. You can find it today as a liquid extract or tincture.
Historically, people turned to this plant for coughs, sore throats, and various skin complaints. Some older systems used it to address what they called lymphatic health. These traditional applications lack strong proof from modern clinical studies.
Use stillingia only in small, carefully measured doses under guidance from a qualified practitioner. The plant contains compounds that can irritate your system. Too much can trigger nausea, vomiting, or diarrhea. Do not use it long term or without supervision.
Avoid stillingia if you are pregnant or breastfeeding. Data on safety is thin, so anyone taking prescription medicines or managing a chronic condition should talk to a healthcare professional first.
