Hello Nexus!
I have a quick question.  I brewed some ayahuasca (vine only) the other day, and since I've never done a harmala extraction, I decided to use my leftovers for it.  After I finished my nine hour brew, I used Gibran2's tek to extract the alkaloids.  I used a total of 450g caapi in my brew, and my harmala yield is about 12.5-13g.  This seems strangely high to me, especially after brewing the same vine that I then extracted from.  
Although I did use a lot of vine, this amount just makes me curious.  I also use lime instead of lye, so I'm wondering if that has something to do with my awesomely huge yield.
Thanks for any replies!  FWIW, the harmalas I have are white and very "chalky" in texture.
