I don't understand - the contact dermatitis was to the tincture? And you got it in the winter?!!! oh that is awful. Just when you think you are safe...
This protocol seems to have worked for me - today is the fourth day.
I know a forager who smears his hands and arms with fresh jewelweed prophylactically whenever he goes to the woods. It releases its juice in a nice gush after ten seconds or so. Maybe try it fresh instead of tincture? I think immediately is important too.
I don't seem to ever get it from my animals, who walk through the stuff all the time. I've seen my dog roll in it. But if I get the tiniest bit anywhere on my body without knowing, a few days later it is all over me, so I am super careful now. If I'm going out to remove PI, I cover myself 100% in clothes that I will dispose of afterwards, shower immediately after using an oil based soap and take rhus tox. It's been years since I've gotten it bad.
Have you tried lavender EO? Helps me a lot with the itch.
thank you for stopping in! come again for coffee sometime.
