Traditional uses

Purplestem angelica was carried in the medicine bags of many Native American nations, including the Iroquois and Meskwaki, who dug its stout root for teas and tonics used against colds, coughs, and sluggish digestion. Some communities also chewed the root or burned it as a protective smoke, believing it warded off illness and bad influences. When European settlers arrived and found their familiar Angelica archangelica absent, they turned to this native cousin, candying its stalks and steeping its root much the same way herbalists across the Atlantic had for centuries. Its old-world name is said to honor the Archangel Michael, whose feast day fell near the plant's traditional blooming time, and settlers long regarded it as a guardian herb kept near the hearth.

Growing guide

Sun
Full sun to partial shade; in hot climates, afternoon shade helps it thrive
Soil
Rich, humus-heavy soil that stays consistently moist to wet
Water
Keep evenly moist at all times; this is a plant of streambanks and wet meadows and does not tolerate drought
Planting
Sow fresh seed in fall, as it needs a period of cold to germinate well; being biennial or monocarpic, it typically grows foliage the first year, flowers and sets seed the second, then dies back, so let a few plants go to seed to keep a patch going

Fresh to dried

Harvest
Dig the root in autumn of the first year or early spring of the second, before the flowering stalk rises, when the root is considered at its most potent
Drying
Wash and slice the root into thin rounds, then dry on screens in a warm, shaded, well-ventilated spot out of direct sun until firm and brittle
Storage
Keep dried root in a well-sealed glass jar away from light and heat, and use within about a year for the best strength
Best forms
Dried, sliced root for teas and decoctions

Did you know?

The species name atropurpurea means dark purple, describing the striking wine colored stems that set this native plant apart from its pale green European cousin, Angelica archangelica.

Safety

Angelica atropurpurea belongs to the carrot family, which includes deadly look-alikes such as water hemlock and poison hemlock, so never harvest it from the wild without expert identification, since misidentification has caused fatal poisonings. Its sap and fresh leaves can cause photosensitivity in sunlight, and it has traditionally been avoided in pregnancy and by people taking blood thinners.
