but in the traditional preparation of ayahuasca, they boil the plant matter for a long time, in order to reduce the liquid to small volume, so i doubt that boiling the solution for long time could destroy the spice.
maybe boiling down could cause the precipitation of tannins, which can form
some water insoluble gunk that capture some parts of alcaloids... but i'm guessing.
and just for washing the extract you could use odourless turpentine, that wouldn't be difficult to obtain wherever you live, (always guessing)
...oh, i forgot, this is my first post here
, i'd like to just say hello to all nice buzzing bees out there
