Botanical description Arnica montana is a herbaceous perennial plant. The plant height ranges from 30-60 cm. One or two pairs of leaves form a flat rosette. They are entire, bright green, toothed and somewhat hairy on the upper surface. The lower leaves are clustered, ovate, ciliated and have rounded tips. The upper leaves are smaller, lance-shaped, opposite and attached directly to the stem. From the center of the rosette rises a round and hairy stalk that ends in 1-3 flower stalks bearing each one orange-yellow daisylike blossom. The fruits are bristly achenes. The rhizome is dark brown, cylindrical, usually curved, and bears brittle wiry rootlets on the under surface. …show more content…

In order to achieve anti-inflammatory efficacy, the active ingredients have to penetrate and subsequently permeate the skin. It has been demonstrated that the the SQLs of different of Arnica preparations show a comparable penetration in and permeation through the stratum corneum. The permeated concentration is sufficient for anti-inflammatory efficacy. It is interesting that isolated SQLs have a significantly poorer penetration performance than the SQLs of an arnica extract and dihydrohelenaline and its derivatives have a better penetration than helenalin derivatives. A gel preparation showed a decrease of the penetration rate over time, whereas the penetration rate of ointments remained constant over
