Traditional uses

High in the meadows of the Alps, Pyrenees, and Carpathians, shepherds and mountain villagers have reached for arnica's sunny flowers for centuries, rubbing infused oils and salves into the aches and bruises that came with a hard day on steep ground. It became so tied to the tumbles of alpine life that old herbals sometimes called it fallkraut, the fall herb. By the nineteenth century it had traveled into European household medicine chests and eventually into homeopathic practice, always applied to the outside of the body rather than taken in, since arnica has long been understood as a topical friend rather than an internal one.

Growing guide

Sun
Full sun, as it would find on an open alpine slope.
Soil
Lean, acidic, well-drained soil, sandy or rocky rather than rich.
Water
Evenly moist but never waterlogged. It resents heavy, wet clay.
Planting
Best started from stratified seed or nursery divisions in early spring. It germinates slowly and can take a couple of seasons to settle in, so patience is part of growing it well.

Fresh to dried

Harvest
Flower heads are snipped just below the base once fully open on a dry summer morning, when their essential oils are richest.
Drying
Spread in a single layer in a warm, shaded, airy spot, out of direct sun, until the petals feel papery and the centers are firm.
Storage
Keep dried flowers in a dark, airtight jar away from heat and light, where they hold their color and potency for about a year.
Best forms
Dried flowers infused into oils, salves, and liniments meant for the skin, never for the teacup.

For the bruise that blooms after a hard fall on a mountain trail.

Did you know?

Alpine shepherds once dried and smoked arnica leaves as a rustic tobacco substitute, which is how the plant picked up its old country name, mountain tobacco.

Safety

Arnica is toxic if swallowed and should only be used on unbroken skin, never on wounds, near the eyes, or internally. It can cause allergic skin reactions in people sensitive to ragweed, chrysanthemums, or other daisy family plants, and it may interact with blood thinners and is best avoided during pregnancy and breastfeeding.
