Yezo Spruce
Picea jezoensis
This plant is kept in the atlas for identification and safety, not for use. Read the safety notes below before handling it, and keep it away from children, cats, and food.
Long before refrigerated ships and vitamin tablets, foresters and sailors across the northern Pacific rim chewed fresh spruce tips or brewed them into tea to fend off scurvy through the long, dark winters. In Hokkaido, the Ainu people knew the tree intimately, using its resin and boughs in daily life and prizing its wood for tools and dwellings. Across Sakhalin and the Russian Far East, the young spring shoots, tender and citrusy, were traditionally steeped as a warming tea to soothe winter coughs and colds. Its wood, prized for resonance, later found a second life as tonewood in pianos and violins made in Japan.
Safety.
Confirm identification before harvesting spruce tips, since spruce can be confused with yew, which is highly toxic. Spruce tip preparations are traditionally used lightly, but the essential oil is for aromatic use only, never internal, and conifer resin can trigger allergic reactions in sensitive people.
