Yuck. Someone posted about LP a few months ago and it sounds just dreadful.
You can find that thread by searching within the forum, but go ahead and enter "Lichen Planus" in the Curezone search window and click "search entire forum" for more experience and suggestions.
Here is Spirit's post from a few years ago which outlines some basic CZ strategies for cleaning up the body:
There's a post with many suggestions, from the
not very frequented lichen planus forum.
Basically you have to view it (as I understand) as an outcome of systemic fungal/yeast infection and clean from the inside out....
Good luck to you and I hope you will stay close to this forum -- it really helps to have support when doing all of this stuff, and people here at OP have a lot of collective cleansing experience -- the LP forum is just not active enough to provide the kind of support that will help you keep moving forward, so stick around OP to get the love and laughter here... !
