I'm pretty sure you guys read TONS of posts like this... sorry about that. But I have tried 3 extractions so far and all of them yielded nothing. So I'm trying to understand what happened.
I was able to get my hands on some, supposedly, MHRB in a market in Mexico. I even bought two different "presentations" from as many vendors. One gave me fully powdered bark and from the other I got regular un-powdered bark (pics below).
My first attempt was with Lazyman's tek using the powdered bark. Nothing. My second and third attempts using Norman's tek. Again, nothing.
Just a quick note from my last 2 extractions: I added less water (due to container capacity). Norman recommends 15ml of water per gram of bark, I used 10. I wasn't able to find VM&P naphtha so I used Zippo premium lighter fluid (I read in several posts that it could be used). Other than that I followed the tek to the letter.
So, as I have nothing to show for my efforts, I would like to to tell me if what I have is actually MHRB. Here are the pics:

The bark cut to smaller pieces:

My VM&P naphtha replacement:

If this is indeed mimosa hostilis then what did I do wrong? Perhaps the Zippo fluid is messing everything up?
Sorry to bother you guys with yet another "I got nothing from my extraction" post... but I could really use a hand

Thanks in advance to everyone!!!
