It's absinthe. It's legal in other countries, but has been banned in the US since the early 1900s. Apparently the government thought it was addictive. It's based on a liquor called Pernod, which is legal, and blue, and being flavored with anise, it tastes like liquorice. Basically absinthe is Pernod with woodwood added. I've never tried it, or tried to make it. I do know woodwood is supposed to be good for getting rid of internal parasites, and is available in just about any healthfood store. I do know absinthe is green, unlike the blue of Pernod. I guess that's what the woodwood does to it. I've heard the stuff tastes pretty awful. Personally, I'll stay with mead, which is honeywine.
