Pure Henna (Lawsonia inermis): Has anyone ever used this on the skin medicinally?

I am aware it has some unique properties. I also read in an Islamic Medicine book that this was recommended for use by Prophet Muhammad (peace be upon him) for healing purposes, on leg ulcers for instance. Am just wondering if anyone has applied pure henna medicinally. Thanks.

Some great answers, very difficult to choose a best.

Well, I had henna done in Morocco for my engagement. My feet were all torn up from poor fitting sandals etc...(long story) and they did the designs on my hands and feet but for the bottom of my feet the woman just covered it in henna (no design) and she told my fiance that it would heal my feet and he translated for me. It worked! They felt 'cooler' and smoother they didn't get hurt as much as long as the henna was there (maybe 6 weeks). And that is even though the woman mixed gasoline with the henna to make it last longer!!!!!!!!!! (I'm not kidding! -- I was wondering what the odor came from--they told me later)

So, not really medical, but it still helped. I'll give you a star.

EDIT: I have a co-worker from Bangladesh who says that henna is supposed to help with hair thinning too. I forgot about that until I read Goldista's answer.
EDIT2: Wow, I just read Mack's answer. I knew about a lot of the essential oils (I've put henna one ppl b4) but didn't know about the terpinol/gasoline thing! Ya learn something new every day.
