Ninety-eight individuals took part in a double-blind randomized study comparing the
effects of a freeze-dried preparation of Urtica dioica (stinging nettles) with placebo on allergic rhinitis. Sixty-nine individuals completed
the study. Assessment was based on daily symptom diaries, and global response recorded
at the follow-up visit after one week of therapy. Urtica dioica was rated higher than placebo in the global assessments. Comparing the diary data
Urtica dioica was rated only slightly higher.
