"Manna of St. Nicholas?"

We're not talking Sanny Claus here, but St. Nicholas of Myra, on whom he was based:

Today he is buried in the Italian city of Bari where his tomb is visited by thousands every year.

An annual ceremony since 1980 goes so far as to extract a clear liquid from his bones called the ‘manna of Saint Nicholas.’ According to the Catholic Church, the extract is said to hold healing properties.

Gah. Wonder how you use it? I ain't gone drink no bone juice.
