Hello, ulli, welcome to the forum.
Though I could not find text for the poem on the Internet, you may want to look into Black Venus by Charles Baudelaire, since the quotation sounds familiar, perhaps, from that work. Baudelaire seeming a relatively popular French poet, one should have little trouble finding his work in any library or bookstore.
I hope I have not made a mistake, but report back if this seems not the poem you search for, for your friend. Good luck!
