If the early game, health potions are pretty cost prohibitive. You might want to save them for emergencies or boss fights. As suggested above, collecting red and blue orchids helps, so does farming the first orc dungeon for health potions, better gear (plus gold and XP).
If you're really struggling, you might want to double check your build, your trait spread and your equipment. Keep in mind that 2-H, 1-H and Light weapons all get damage bonus from a different mix of traits (see the Wiki for more details).
