toxicity

How poisonous is Helenalin? How can it is used as an anti-inflamatory and is toxic? —Preceding unsigned comment added by 72.174.52.160 (talk) 02:49, 15 November 2007 (UTC)[reply]

Here's the ld50 in mice: http://toxsci.oxfordjournals.org/cgi/content/abstract/10/2/302 I'm not sure what cutoff would make something "highly toxic," however. Regarding anti-inflammatory use, I know arnica derivatives historically have been applied topically, and there are some citations regarding topical treatments on the a. montana page.
