Grindelia Tincture & Alcohol-Free Extract

Grindelia (Grindelia robusta), the great valley gumweed, is a perennial of the daisy family, Asteraceae, native to California and the Pacific coast of North America. It grows 30-100 cm tall with stiff, toothed, resin-dotted leaves and yellow daisy-like flower heads whose buds are covered with a thick, white, sticky resin, which gives the common name gumweed. The whole plant has a balsamic smell and a bitter, resinous taste. We extract the dried herb.
