Traditional Uses
In Korea, Synurus deltoides is cultivated and gathered both as a wild mountain vegetable and as a folk medicine used for inflammatory disorders. Its anti-inflammatory reputation is supported by pharmacological study: an ethanol extract of the plant suppressed LPS-induced pro-inflammatory cytokine production in RAW 264.7 macrophages and reduced acute inflammatory symptoms in vivo (Lee et al., 2014, BMC Complementary and Alternative Medicine). No Native American use is documented.

Botanical Description
Synurus deltoides is a robust, thistle-like perennial herb of the daisy family (Asteraceae), distributed through Korea, China, Japan and southern Siberia. It grows in mountain grassland, scrub and forest margins, sending up tall, branching, often cobwebby-woolly stems to around a metre or more. The large lower leaves are broadly deltoid to ovate with toothed margins, dark green above and densely white-felted beneath, the upper leaves becoming smaller and narrower up the stem. In late summer and autumn it bears solitary, nodding, globe-shaped flower heads with spreading involucral bracts and clusters of purplish tubular disc florets, somewhat resembling a knapweed or thistle. In Korea the tender young shoots and leaves are gathered or cultivated as a wild mountain vegetable, and the plant is also valued as a folk medicine.
