I just bought Hyland's Poison Ivy/Oak remedy with Rhus Tox. I take 3 pellets every 2 hours (this is day 2) and it doesn't seem to do anything. Also, I did get it in my mouth (my tongue/gums/sides of mouth moderately itchy) and into my system. I know this because I started getting a weird headache and stomachache. Is the homeopathic remedy advisable in my case and if so, how long does it take to obtain relief? Any help would be appreciated.
