Thanks Stush! It is good to have a remedy ready if one fails to avoid the sap, and for those who develop a sensitivity to things that didn't bother them before. I've gotten really weird about it, stopping to wash my hands several times while packing up a box for trade last week. (Then went camping and am scratching a ton of bug bites as we speak - seems I'm just destined to be scratching, one way or another, most of the things I enjoy cause itching!)
Kristi, I think that's why they call it rue? Its' reputation keeps me away, no doubt. There's a whole 'nother slew of plants outside that can make me itchy, even before my skin 'turned sensitive.' Juniper and nightshade vine come to mind first, though luckily the itching and (longevity of it) from those is not in the same league as a latex or Philodendron rash - personally. Others' experiences may vary.
It sounds like it may be best to avoid most contact with plants in the heat of the day (as if the heat itself wasn't enough of a factor.)
