Dwarf Birch

Betula glandulosa

Dwarf birch is a small, hardy shrub of the far north, so low and wind-pruned across the tundra that caribou and moose graze it like grass. Northern Indigenous peoples across Alaska and Canada have long relied on it for practical, everyday needs, its resinous, glandular twigs catching a spark quickly as tinder, and its wiry branches bundled into brooms and snowshoe lashings. Like its taller birch cousins across the boreal world, its leaves have also been steeped into a simple tea in some northern communities, part of a much wider birch-leaf tradition of gentle, everyday tonic teas used to support the kidneys and ease stiff joints after a hard season of work. It is a plant defined less by grand medicinal fame and more by quiet, constant usefulness.

Safety.

No significant toxicity is documented, but those with birch pollen allergy may notice oral itching from raw plant parts. Birch leaf has a diuretic effect, so it is best avoided with kidney disease, diuretic medication, or pregnancy without medical guidance.
