50 Arnica montana seeds, 'Mountain tobacco'
Arnica montana is usually propagated from seed. Generally, 20% of seeds do not germinate. Seeds sprout in 14–21 days. Arnica likes a mixture of loam, peat and sand. The leaves form a flat rosette, from the center of which rises a flower stalk, one to two feet high, bearing yellowish flowers. The rhizome is dark brown, cylindrical, usually curved, and bears brittle wiry rootlets on the under surface.
Arnica is a standard herb in homeopathy. Although Arnica montana's main pharmacologically active constituent (helenalin) is safe and beneficial in the very small quantities when used EXTERNALLY in herbal medicine (as an anti-inflammatory and analgesic), it is extremely toxic in large doses. Moderation, grasshopper. Never use internally.
