If you are just finding it difficult to locate the potion you want from your inventory due to the rather haphazard naming scheme the game uses you may want to check out some mods that provide better item sorting. For example, go to Skyrim Nexus and search for the following (I can't post links yet):
Valdacils Item Sorting - Should be the only item in the search results.
Better Sorting - look at the last item on the last page of results.
These mods appear to both perform essentially the same job (renaming things so they sort better) but follow slightly different sorting philosophies. So you may want to read the descriptions of each to see if one of them meets your needs. Note that I have not tried either of these myself yet (too busy playing with the creation kit to actually play the game

) so I can't personally vouch for them but they look pretty interesting based on their descriptions.
