Does anyone know what is on Jagermeister?

I forget all the different herbs in Jager, but every bottle does have a few drops of reindeer blood in it. Jagermeister in German means "Master Hunter". Traditionally, hunters drink the blood of their first kill. Also, the writing around the logo is a hunter's poem:

"This is the hunter’s badge of glory,

That he protect and tend his quarry,

Hunt with honour, as is due,

And through the beast to God is true."

And yes, any alcohol will mess up your liver if you drink heavily on a regular basis. Drinking in moderation (at a pace that your liver can process) will decrease the harm done.

Liquid fun.
