Arnica

Reasonable topical option for bumps and mild soreness, but it should not be used orally or on broken skin.

A rough internal score reflecting quantity, quality, and consistency of human evidence. Not a clinical recommendation.

Trials of gels and creams show mixed but generally plausible benefit for bruising, swelling, and post-exercise soreness. Oral arnica is not considered safe.

• May reduce bruising and local swelling
• Useful for short-term topical soreness support
• Has anti-inflammatory sesquiterpene lactones

Use only as a topical gel, cream, or ointment according to the product directions.

• Skin rash
• Contact dermatitis
• Toxic if swallowed

Do not ingest. Avoid broken skin because systemic absorption can increase toxicity risk. People sensitive to ragweed-family plants may react.

Evidence is stronger for topical use than for oral use, and results vary a lot by preparation.
