Hi Sophie:
	I have a small tissue culture lab in my house, used right now for 
establishing local medicinal and rare herbs. In my folklore end of info 
searching, I have come across a few mentions of horse chestnut being used 
as a sun block by Native North Americans. I believe it was a paste made 
of the ground leaves and nuts. I have done a UV absorption scan on a 
clarified extract of some leaves, and found a trough in the UV region. 
Just mentioning this in case this is a general phenomenon in trees or 
whatever. Good luck.
