He should be near the fence of the chieftains house.
But if my surprisingly daft short term memory serves me right, you have to speak to the alchemist once you have all the ingredients. After that, the alchemist should lead you to the shamans basement through a secret tunnel.
Remember you need all 3 ingredients, and if you do have all of them, you'll get a speech option for the alchemist asking him for the cure.
EDIT: Blast! Too late... again... hate when that happens...
