I have been given this drink as gift, but I don't know what it is? Can anyone please tell me what this drink is?
Oh-Bal-Ju is liquor from N.Korea. (of course you can buy in S.Korea)

It is made with 9 traditional Korean medicinal herb.

OH means crow, Bal means hair, Ju means liquor - If you drink this, you can live long as crow and white hair will change to black.

You can see a picture of it here North Korean DMZ store
