Firstly, sassafras oil, although watched can be fairly easily extracted and so far as I know sassafrass is not endangered. The File in gumbo, I believe, is all you need to start. Getting the safrol from the sassafras is a bit more difficult but then again, you may be making this stuff yourself now and I am not telling you anything that you don't already know.
Secondly, one of the reasons I occasionaly post the way I do is to get people to visit my grow journal. There are ocasional disparities between who I seem to be when I post and what we are accomplishing in my grow.
