Oh, if you go the transmute way, then you can as well do it while your follower chops some firewood. He chops, you cast. Two tedious things done simultaneously.

Also, Giant Toes + Blue Butterfly Wings + Blue Mountain Flowers gives potions that are worth SO much more than other potions. If you want to powerlevel Alchemy a bit, they're the way to go. But of course, 200 potions made of useless Purple Mountain Flowers and Thistle Branches or something like that are also worth a bit. It's just that the Giant Toes are the best ingredient for really valuable merchant fodder.
