"Battlemage's Brew": Regenerate Health and Regenerate Magicka. Ingredients - Juniper Berries, Garlic and salt pile. Namira's rot would work in a pinch if you don't have juniper.
"Crafter's Elixir": Fortify Enchanting and Smithing. Ingredients - Blisterwort, snowberries and spriggan sap (usually available in alchemy shops and is much easier to get.).
When you're a PC player, maybe the Alchemist Compendium mod is something for you.
