I add a touch of fresh mullein before lighting it up, that takes away any harshness or bad taste.

Its defiantly excess Harmala, bearing in mind the vine is full of the stuff but my thoughts at the moment are that the Vine is revered more than the spice, so get it in yu, she is the Mother of all plants after all.

I'm gonna bong some minus the Mullein today, so I'll see how harsh it is on its own.
