I found this receipe - chuinese herbs or something - for insomnia:

Fillet of a fenny snake,        
In the cauldron boil and bake;        
Eye of newt and toe of frog,        
Wool of bat and tongue of dog,        
Adder's fork and blind-worm's sting,        
Lizard's leg and owlet's wing,        
For a charm of powerful trouble,        
Like a hell-broth boil and bubble.        
Scale of dragon, tooth of wolf,        
Witches' mummy, maw and gulf        
Of the ravin'd salt-sea shark,        
Root of hemlock digg'd i' the dark,        
Liver of blaspheming Jew,        
Gall of goat, and slips of yew        
Silver'd in the moon's eclipse,        
Nose of Turk and Tartar's lips,        
Finger of birth-strangled babe        
Ditch-deliver'd by a drab,        
Make the gruel thick and slab:        
Cool it with a baboon's blood,        
Then the charm is firm and good.

I've been assured it works..
