I'm having a lot of trouble with this one.

Be careful with that stuff.....

... According to Snape, if you did combine Powdered Root of Asphodel and an infusion of Wormwood, you'd brew a sleeping potion 'so powerful it is known as the Draught of Living Death.

 

What would I get if I get if I added powdered root of asphodel to an infusion of wormwood?

 

a sleeping potion "so powerful it is known as the Draught of Living Death"

 

Next time try  

 

Eye of newt and toe of frog,  

Wool of bat and tongue of dog

according to what I found with google, it will create a powerful sleeping potion.   I gave a more complete answer the first time, and it was removed, presumably by a moderator.  I don't know why, they never give you a reason.
