sigh nope.. Or at least partially correct, but barking up the wrong tree..
"Pure" Absynthe is still made, minus the two herbs that make you fly. It's called "Pernod", after the brothers who trademarked the distillate.
It isn't all that different from Rakya or Ouzo, and if you can get your grubby paws on the real stuff... it's 80% alcohol... Which is why you water it down...
Trademarks having as much use as enforcing patents in China in those days, and absynthe being
really popular, people copied it while cutting corners selling it as "real" Absynth.
Except that they got the trademark green colour not from the proper method using a very specific and pretty expensive cultivar of wormwood, but ferrous chloride.
Which, indeed, is a neurotoxin. With a certain painter being the most post-humously famous victim.
The low-quality moonshine-type alcohol that was used by the copycats (actual Pernod uses expensive! double-distilled wine alcohol..) may well have contained methanol and the higher alcohols, giving a triple-whammy in the "how to drink yourself silly" department.
Not having a grip on the production on any of this, the french and spanish governments blamed the wormwood, and banned anything called "Absynthe", along with a host of other measures, like making it illegal to home-distill alcohol. And taxes... there must be taxes!!
The brothers Pernod simply took out the wormwood, rebranded the drink to their name, and got a license to produce, giving us the modern drink you get anywhere at a decent specialist in fine liquor.
As to how to Complete a bottle of Pernod... I suggest the Internet...
(or, if you live in the right countries... Pernod makes the stuff again. Not as strong, because Regulations!! but still...)
