how to determine if henna powder contains green dye?

Posted by Holly on April 5, 2004 at 17:05:25:

I've been looking around mehandi.com's '60x' section for the info on
various brands of henna powder that often contain green dye to make
them look fresher... Some brands aren't always consistent, and some
exporters aren't always honest about the exact contents of "natural
henna powder"...

That being said, I don't have a microscope handy. I hope that someone
here would know of way to do this by other means! I read somewhere
that coal tar dyes do not "rub off" of dampened paper/cloth like any
other kinds of dye might (but I can't find that info back). I have
scanned the the Forum archives (thank you elves!) but I might've
missed something.

Thanks in advance!!!
