Probably a bit late in the season for a post, but maybe someone will see it....we are still trying to figure out what plant found on the GR20 can cause severe blisters on the skin.

We first noticed them on the legs of a women who was walking the GR20 at the same time as us, back in late July. She had huge fluid-filled blisters on her legs. One of the gardiens said he knew that it was from a plant found only on Corsica.

A couple of days later, my wife developed similar blisters on both wrists. They were tense, slightly bloody-fluid-filled blisters. When we got to Vizavona, she asked a local doctor who was staying in our hotel; he had never seen anythign like it but gave her some steroids to settle it down.

Now, a few months later, they are still not properly healed. We cannot find any onformation on the internet about such a thing. Does anyone know if this is casued by a plant and, if so, what it is called?
