Perhaps I haven't found the right things/places to harvest bulk ingredients for valuable potions. Most of the ones I end up making are 100-300 value. Only reason my Alchemy gets along as far as it does is because you can train at the Whiterun shop and then sell off the million potions you've made to get some of your cash back. And Smithing's still faster.
There have been couple of people on this board who have been on the Chaurus Egg + Luna Moth kick.
I get excited when I see blue mountain flowers, and salt, and deathbell.
Salt + Deathbell = Slow poison. good money.
Blue Mountain Flower + Blue Butterfly WIng = Damage Magicka Regen
I'm usually able to get to 100 just making these two potions.
I take potion strength perks as soon as I can get them. There are 8 of them. And I also get 3 Experimenter perks for convenience. 11 perks. I like alchemy. It makes you rich.
