Arnica tincture diluted with water (1:5 to 1:10), applied as a compress for insect bites and superficial skin irritations (not on open wounds). Apply compress with a clean cloth to the affected area, leave for 15-20 minutes. Kommission E explicitly lists insect bites as an indication for external arnica preparations. Only on intact skin — use on open wounds is contraindicated (local mucosal irritation, contact dermatitis risk).

Standardised arnica gel (50 g arnica flower tincture per 100 g, equivalent to ~15 % mother tincture) clinically studied for osteoarthritis of finger joints and knee: In randomised controlled trials (e.g. Knuesel et al. 2002, Wiesenauer 2004), arnica gel showed comparable efficacy to ibuprofen gel in pain reduction and improvement of joint function. Apply 3 times daily to affected joints for at least 3-6 weeks to assess benefit. Use only as adjunct, not as replacement for physician-prescribed osteoarthritis therapy.
