Even f the rash is old, swollen n leaking fluid, comfrey is probably the only medicinal herb that immediately stops the itching n starts the healing. Personal experience. It is truly better than the expensive otc junk, hot showers - which seems to aid in spreading the itchy oils systemically, and the other stuff I've tried which seem useless after the initial set in stage.
