Traditional Use: Used for centuries in European folk and homeopathic medicine as a topical remedy for bruises, sprains, muscle soreness, joint pain, and minor wounds; traditionally applied after physical trauma and surgery to reduce swelling, pain, and discolouration.
Potential Benefits: Sesquiterpene lactones (helenalin) and flavonoids deliver well-documented anti-inflammatory, analgesic, and antimicrobial effects topically; clinical trials support significant reduction in bruising, post-surgical swelling, osteoarthritis pain, and muscle soreness with quality topical preparations.
Warnings: Strictly for external use only — internal use is toxic, causing severe gastric irritation, cardiac arrhythmias, and organ damage; never apply to broken or open skin; may cause allergic contact dermatitis in those sensitive to Asteraceae plants; homeopathic oral preparations are highly diluted and considered safe by different mechanisms.
