I searched for "medicine absinthe" and got an article from
a medical school in Miami. Here is the concluding paragraph:

"Prolonged drinking of absinthe causes convulsions, blindness, hallucinations, and mental deterioration. Absinthe has been banned but something of its taste of absinthe is still available in such drinks as ouzo in Greece and in France, pastis, long considered "the mother's milk of Provence."

P.S. Thanks for all those kind words.
