What if you make it up yourself? I studied a bit about arnica and plan to do more, and have ordered the herb in pure leaf/root form, however it comes, and want to test out making my own ointment based on it along with some lavender, tea-tree and perhaps frankinsence essential oils. You could also mix it with other herbs to make capsules, or you could make a tincture out of it, both for internal consumption if needed.
