Recently I have worked with quite a few Harmala Manske extractions after obtaining 5 kilo Peganum Harmala seeds only 20 dollar, from a visit to Turkey.
They use it as incense to fight of bad energy and when they get a new born to make sure they will be healty as they grow up.
I love this extraction with the coulour changes and easy purifications.
The only thing that is a bit pain is the filtration.
So I tried to put the grinded seeds in a linen cloth bag and did the 3x boils in that. It worked wonders, Filtration is a lot easyer after and the loss in yield is almost nothing.
Tried the same boil in bag technique with an A/B MHRB with Vinegar,NaOH and heptane, yielded 1.54% (didnt have enough Bark to do a side by side without bag).
Best of luck
