From flowerheads of Arnica angustifolia ssp. attenuata nine helenanolides, two 1,5- trans-guaianolides, and a mixture of inositol-tetraesters were isolated. Five of the helenanolides are described for the first time. One of them, 4- O-tigloylarnicalpin, is the first 7(12),6-trans-lactonized pseudoguaianolide isolated from a natural source. The occurrence of inositol esters within the genus Arnica has

The present disclosure relates to the use of the sequiterpene lactones and Helenalin (H. tox) or its derivatives to treat viral infection and virally induced lesions, such as warts or wart-associated skin or mucosal lesion. A topical application, optionally using a skin covering such as gauze, a bandage, or a patch, can substantially reduce and even eliminate persistent, recurrent and/or treatment-resistant warts.
