Can't Get Rash About Rashes

The last time I had a noticable rash was when I was backpacking between farms in 2007. I developed a large one on the back of my calf. So drank dandelion root tea to cleanse out my liver - and it totally did the trick.

Something has manifested on my right arm (oh the metaphorical implications) and perhaps I will never learn the cause. -> You probably can't see it that well in this pic.

But I want to clear it up as soon as possible. Herbalists say it's important to eliminate toxins from the liver. Ironically I'd made a decoction of dandelion root, burdock and oregon grape last night. Then today the rash appeared. Hmmm...

Homemade Medicine - contains a bunch herb recommendations that could be mixed into teas

Natural Herbal Healing (FreeWebs) - suggests making polstices of herbs I hadn't thought to use, such as oats (one of the most common ingredients for soap - of course). I sure wish I had a clean bathtub to soak in oats with!

Natural News - discusses a variety of treatments from food to ointments, with an emphasis on dealing with allergies

But really I just need a little time to pass...
