Avid listeners of this podcast may recall my past revelations that I have a super power. When I encounter poison ivy or poison oak, even in the tiniest amount, my body’s immune system explodes in a systemic reaction, creating a situation that requires fast treatment. It’s itchy, uncomfortable, and I’ve spent many sleepless weeks on steroids trying to keep the rash at bay. 

Well, stop rolling around in poison ivy, you might be thinking. I wish! Unfortunately, for me, it’s usually my dog that frolicks in the plant. Dogs do not react to the plant’s oils, so she carries on none the wiser but brings the oils to me.
