It has worked for me. I've done the Manske twice and used whole seed both times. It worked fine.
I had read that paper and the statement therein, stating that the harmala alkaloids are found 'wholly within the husks'. It seemed to me it would work....and it did.
I don't have notes from those extractions, so I can't give you any numbers, but I remember the yields being good.
Try it.
