You can select multiple effects and see the ingredients that are needed for such a potion or posion. Additionally you can also simply select ingredients and see which ones match. Here also multiple selects are possible.
The http://skyrim.melian.cc/?cmd=cmdSkyrimAlchemyWizard really lets you delve into potion and poison creation, letting you create potions and poison easily with 3, maybe even 4 effects!
Go have a look. I already found some nifty poisons with 3 negative effects



Thank you too
