Arctic sweet coltsfoot is a perennial plant and grows to a height of 10 to 20 cm. Butterbur flowers appear in February to March, before the larger leaves that grow in late spring. The flowers have a sweet scent and are often the first blooms of the new year in the cold, damp areas of the north. A cluster of white to purplish-pink flower heads appears at the tip of a fleshy stem covered with bracts. The flowers develop into silvery-white seed heads, and the large, rhubarb-like leaves grow near the flower stalk directly from an underground rhizome. The basal leaves are palmately divided and have woolly white hairs on the underside.

🛑 Only the mature leaves of Arctic butterbur should be collected, as the young leaves contain small amounts of pyrrolizidine alkaloids, which are hepatotoxic.

Arctic butterbur should not be used for liver problems, during pregnancy and breastfeeding and for children under 7 years of age. Adverse reactions may include gastrointestinal symptoms, nausea, bloating and abdominal distension. Allergies are possible.
