Not sure who all is still interested in this thread or any of the continuing research I am doing, but what I have found includes tariff reports from Japan, where I. verum is not native, shipping out star anise; botanical differentiation did not occur until 1881, but star anise was still referred to as I. anisatum in the literature for years to follow; aniseed oil was actually mostly made from star anise (a paper from 1903); another 19th century paper stating that of all the essential oils that go into absinthe, aniseed oil is the one that causes symptoms most closely resembling absinthism. Also, I am tracking down a source that states that during distillation of absinthe a scent like cinnamon or cloves wafts thought the air (distillers, feel free to chime in) which might seem irrelevant but one way to theoretically differentiate between I. verum and I. anisatum is that I. anisatum smells faintly of cloves.
All together it is enough for me to go into the lab and distill some absinthe for science! But before I do that, I need the appropriate verification materials so that if I publish a paper it holds up to scrutiny. Also, I need a good source for Illicium anisatum, but that's a different can of worms. Therefore, if anyone can help, or knows someone who can help, please pass this along: www.gofundme.com/olqivk
Thank you all!
